Should I Pay Percentage of Collections or Per-Claim for Medical Billing?
Percentage of collections (typically 4-9%, median 6%) wins when your average payment per claim is high (over $150), your denial rate is elevated (over 6%), or you need the vendor strongly incentivized to work denials and aged A/R because their revenue scales with what you actually collect. Per-claim pricing (typically $4-$8 per claim) wins when your average payment per claim is low (under $80), your claim volume is high relative to revenue (high-volume primary care, urgent care, lab, behavioral health on flat-rate session codes), and you have stable denial performance you do not need the vendor to materially improve. The hidden cost in per-claim pricing is misaligned incentives on denial recovery; the hidden cost in percentage-of-collections is paying more on high-dollar claims that did not require commensurate work.
- Percentage of collections range: 4-9% (HBMA member surveys, median ~6%)
- Per-claim pricing range: $4-$8 per claim (industry standard)
- % model aligns vendor with collected revenue (incentive: work denials)
- Per-claim model aligns vendor with submission volume (incentive: throughput)
- Average claim value of ~$120-$150 is the rough breakeven
- % model favors specialty + denial-heavy practices
- Per-claim favors high-volume + low-dollar practices
Percentage of Collections vs Per-Claim Pricing
Last updated
Medical billing vendors price under two dominant models: a percentage of net collections (typically 4-9% per HBMA member surveys) or a flat fee per claim submitted (typically $4-$8 per claim per industry vendor pricing). A small minority of vendors offer hybrid or per-FTE pricing, but the % vs per-claim choice covers the overwhelming majority of contracts. The choice is not arbitrary. The two models embed different incentives, allocate financial risk differently, and produce materially different total cost outcomes depending on a practice's payer mix, average claim value, and denial rate. A percentage-of-collections model aligns the vendor's revenue with the practice's revenue — when the practice gets paid more, the vendor earns more, which incentivizes denial work and A/R follow-up. A per-claim model aligns the vendor's revenue with claim volume — when more claims are submitted, the vendor earns more, regardless of whether those claims actually pay. The right answer depends on three variables: average net payment per claim, denial-rate baseline, and how much the practice trusts the vendor to actually work denials. This guide walks through the math behind each model, the incentive structure each creates, the practice profiles for which each model wins, and the contract clauses that protect the practice in either case. The reference data is HBMA member-survey pricing, MGMA cost-to-collect benchmarks, and standard industry vendor-pricing structures.

How Each Pricing Model Actually Works
Percentage-of-collections pricing means the vendor invoices a stated percent of your net collections each month. 'Net collections' is a critical defined term: it should mean dollars actually received from payers and patients in the billing period, after refunds and write-offs, but excluding refunds of overpayments and excluding patient credits. The percentage is typically applied to all collected dollars, not just collections from claims the vendor submitted, which means the vendor is paid on aged A/R recoveries from before the relationship started — read your contract on this, because it varies. HBMA member surveys put the typical range at 4-9% with median around 6%; specialty-billing services (mental health, anesthesia, pain management) often quote 7-9% because of higher per-claim complexity. The invoice is monthly, calculated on the prior month's actual receipts. Per-claim pricing means the vendor invoices a flat fee for each claim submitted, regardless of whether the claim is paid, denied, or partially paid. Industry-standard rates run $4-$8 per claim, with cleaner-volume vendors at the lower end and specialty/complex-claim vendors at the higher end. Some per-claim vendors charge a separate fee for resubmissions (so a denied-and-resubmitted claim becomes two billable submissions), which materially changes the economics. Some per-claim vendors offer a denial-recovery add-on (a separate per-denial-worked fee) but most do not, which is the structural incentive problem covered below. Hybrid models exist: a base monthly fee plus a small percentage, a per-claim fee plus a percentage of denial recoveries on a contingency basis, or per-FTE pricing where you essentially rent a dedicated biller. These are minority structures; the % vs per-claim choice covers most contracts.
The Math: When Each Model Costs Less
The breakeven point between the two models depends on average payment per claim and denial rate. Walk through the example math to see why. Example 1, primary-care practice: average payment per claim is $115, monthly claim volume is 1,200, monthly net collections are $138,000. At 6% of collections, the vendor invoice is $8,280 per month. At $5 per claim, the invoice is $6,000 per month. Per-claim wins by $2,280 per month, or roughly 27%. Example 2, mental health practice: average payment per claim is $135 (90837 hourly psychotherapy), monthly claim volume is 800, monthly net collections are $108,000. At 7% (specialty rate), the vendor invoice is $7,560. At $6 per claim, the invoice is $4,800. Per-claim wins by $2,760, or 36%. Example 3, orthopedic surgery practice: average payment per claim is $620 (mix of E&M and surgical procedures with high RVUs), monthly claim volume is 400, monthly net collections are $248,000. At 6%, the vendor invoice is $14,880. At $6 per claim, the invoice is $2,400. Per-claim wins by $12,480, or 84%. Example 4, pediatric practice with 12% denial rate: average payment per claim is $95, monthly submitted claim volume is 1,500 (but only 1,320 actually pay due to denials), monthly net collections are $125,400. At 6%, the vendor invoice is $7,524. At $5 per claim on 1,500 submissions plus $5 per resubmission on 180 denials, the invoice is $8,400. Percentage wins. The pattern: per-claim pricing arithmetically beats % of collections when average claim value is moderate-to-high; % of collections wins when claim volume is high relative to revenue or when denials require substantial rework. The breakeven on average claim value (at 6% vs $6 per claim) is exactly $100 per claim; below $100, per-claim is more expensive, above $100, % of collections is more expensive.
Incentive Alignment: The Hidden Cost in Per-Claim
The arithmetic favors per-claim in many practice profiles, but the incentive structure does not. This is the most underappreciated factor in pricing-model selection. Under percentage-of-collections pricing, the vendor's revenue is a direct function of what you actually collect. A denial that does not get worked is the vendor's lost revenue too. An aged A/R balance that goes unrecovered is the vendor's loss too. This creates strong, mechanical incentive to work denials, follow up on aged A/R, appeal underpayments, and recover patient responsibility — because every dollar collected is some cents to the vendor. Under per-claim pricing, the vendor is paid on submission, not on collection. A clean claim that pays first-pass and a claim that denies and goes unworked produce identical revenue to the vendor. The vendor's incentive is throughput: submit as many claims as quickly as possible. Denial work, A/R follow-up, and appeals are pure cost to the vendor without offsetting revenue. Some per-claim vendors offset this with internal SLAs and quality controls, but many do not, and the result is what HFMA and HBMA both note in their member literature: per-claim billing relationships often produce higher submission volume but lower net collections than percentage relationships, particularly in practices with elevated denial rates. The practical implication: per-claim pricing is structurally appropriate only for practices with already-strong denial rates (under 4%) and stable A/R, where there is no material denial-work upside the vendor would need to be incentivized to capture. For practices with elevated denial rates, the apparent per-claim savings are often illusory because the vendor leaves recoverable revenue on the table. A 3-percentage-point net-collection-rate gap on $1.5M of annual revenue is $45,000 — easily exceeding any per-claim pricing savings.
Risk Allocation: Who Bears the Downside
Pricing models also allocate financial risk between practice and vendor differently. Practice owners often miss this dimension entirely. Under percentage-of-collections, the vendor shares downside risk with the practice. A bad payer-mix month (high commercial-payer denials, slow Medicare adjudication, etc.) reduces the vendor's invoice along with the practice's revenue. A practice that loses a major payer contract sees its vendor invoice fall proportionally. The vendor is a partner in revenue performance; their cash flow tracks yours. Under per-claim pricing, the vendor is insulated from collection risk. The vendor invoices the same per-claim fee whether collections boom or collapse. A bad month for the practice is the same revenue month for the vendor. A practice that loses a payer contract continues paying per-claim fees on whatever residual volume exists. The vendor's cash flow is decoupled from yours. For practices with stable, predictable payer mixes and revenue, this risk-decoupling does not matter much. For practices with volatile revenue (new practice ramping up, practice in a major payer renegotiation, practice in an acquired or merging market), the % model's downside-sharing is materially valuable. For very large stable practices that view billing as pure operations, the per-claim model's predictability has real planning value. This is also why hybrid models (small base fee + small percentage) exist: they distribute risk in a way that pure-% or pure-per-claim does not. A small base ensures the vendor cannot lose money on a slow month; a small percentage keeps incentive alignment on collections.
Contract Clauses That Matter More Than Headline Rate
Once you choose a pricing model, the contract clauses around it determine whether the headline rate is the actual cost. The following are the highest-leverage clauses to negotiate. For percentage-of-collections contracts: define net collections explicitly (which payer adjustments and patient credits are included or excluded), specify whether the percentage applies to aged-A/R recoveries from before the contract started (some vendors charge full % on legacy A/R they barely worked), specify a floor (a minimum monthly invoice that protects the vendor) only if you want to share that risk, specify a ceiling on invoice as % of revenue (rare but worth requesting on high-revenue practices), and specify how refunds and recoupments affect prior invoices (clawback or no clawback). For per-claim contracts: define what counts as a 'submitted claim' (corrected claims and resubmissions are the most common dispute), specify whether secondary and tertiary claims count as separate submissions or are bundled with the primary, specify whether denial-rework triggers an additional fee, specify whether eligibility verification and prior authorization carry separate fees, and specify the volume tier breakpoints if pricing is volume-discounted. For both: contract a 60-90 day termination clause without auto-renew penalty, contract data-portability (return of all PM-system credentials and historical data on termination), contract a no-poach of patients/referrers, and contract KPI-tied performance SLAs (denial rate, days-in-A/R, net collection rate) with right to renegotiate or terminate on SLA failure. The headline rate is rarely the largest cost variable; the contract architecture usually is.
Practice Profiles: Who Should Choose Which Model
Distill the cost math, incentive structure, risk allocation, and contract considerations into clear practice profiles. Choose percentage-of-collections if: your specialty has high denial complexity (mental health, oncology, cardiology, pain management); your average payment per claim is under $150 and you have moderate-to-high claim volume; your current denial rate is over 6% and you need the vendor incentivized to drive it down; your practice is in growth mode and you want vendor cost to scale with revenue rather than as a fixed line; you have meaningful aged A/R that needs recovery (over 20% of A/R aged 90+ days); or you are a new practice ramping up and unable to predict claim volume. Choose per-claim if: your average payment per claim is over $200 (high-RVU specialty surgery, ortho, cardiology procedures, certain dental codes); your current denial rate is under 4% and stable; your claim volume is predictable and you want fixed-cost predictability for budget planning; you are a high-volume low-dollar practice (urgent care, primary care, lab, urgent care) where the % math punishes you; or you are a very large practice (20+ providers) where per-claim economies-of-scale make the math decisive. Consider hybrid if: you want strong denial-work incentive but are uncomfortable with pure-% on a high-revenue/high-claim-value mix. A small base + small % can capture the right incentives without paying full percentage on every collected dollar.
When to Choose Each Option
Percentage of Collections Pricing
Choose percentage of collections if your specialty has elevated denial complexity, your average claim value is under $150, your denial rate is above 6%, you need vendor incentive aligned with collections rather than submissions, you have meaningful aged A/R needing recovery, or you are a growing or volatile-revenue practice that benefits from variable rather than fixed billing cost. The model's strength is incentive alignment: the vendor only earns when you collect, which drives denial work and A/R follow-up.
Per-Claim (Flat Fee) Pricing
Choose per-claim pricing if your average payment per claim is over $200 (high-RVU surgical or procedural specialties), your current denial rate is under 4% and stable, your claim volume is predictable, or you are a very high-volume practice where the % model's economics punish you on each high-dollar claim. The model's strength is cost predictability and arithmetic savings on high-dollar claims, but the incentive trade-off is real: the contract must explicitly require denial-work and A/R-recovery SLAs because the pricing structure does not naturally incentivize them.
Percentage-of-collections is the right default for most physician practices because of incentive alignment: the vendor's revenue scales with what you actually collect, which drives denial work, A/R follow-up, and recovery on aged balances. Per-claim is appropriate for high-volume low-dollar settings, very large practices with stable strong denial performance, and surgical-specialty practices where average claim value makes the % math punitive. The headline rate matters less than the contract architecture: defined-term clarity, KPI-tied SLAs, no auto-renew penalty, data portability, and explicit denial-work standards (especially under per-claim pricing) determine whether the headline rate is the actual cost. Choose the pricing model that aligns vendor incentives with the practice's primary revenue-cycle weakness; negotiate the contract clauses that make the headline rate the real rate.

HBMA (Healthcare Business Management Association) member-pricing surveys consistently place the typical range at 4-9% of net collections, with the industry median around 6%. The variance within that range is driven primarily by specialty complexity and practice volume. High-volume primary-care practices with simple payer mixes and clean claims often pay 4-5%. Mid-complexity multispecialty practices and standard specialty practices typically pay 5-7%. High-complexity specialty billing (mental health with extensive prior-authorization rules, anesthesia with time-unit billing, oncology with infusion and 340B drug tracking, pain management with compliance-heavy procedures) often pays 7-9%. Vendors quoting outside this range warrant investigation: below 4% may reflect a per-claim or hybrid model in disguise, above 9% may reflect a niche specialty premium that should be priced explicitly.
What is the average per-claim cost for medical billing?
Industry-standard per-claim pricing runs $4-$8 per submitted claim, with $5-$6 being the most common quote for general practices on standard CMS-1500 work. The variance reflects volume tier and complexity. High-volume vendors (over 100,000 claims per month under one contract) sometimes quote $3.50-$4.50 per claim. Standard mid-volume contracts (10,000-50,000 claims per month) typically quote $5-$6. Specialty or low-volume vendors quote $6-$8 because of fixed-cost amortization on smaller volume. Per-claim contracts may charge separately for resubmissions ($2-$5 per resubmission), eligibility verification ($1-$3 per verification), prior authorization ($15-$50 per authorization, sometimes contingency-based), patient statement processing ($0.75-$1.50 per statement), and patient-pay collections (typically a percentage). The total cost-per-claim including these add-ons often runs higher than the headline rate, so the apples-to-apples comparison must include them.
Which pricing model is more common in the industry?
Percentage of collections is the dominant model, used by approximately 70-80% of professional-billing vendors based on HBMA member-survey data, particularly for small and mid-sized physician practices. Per-claim pricing is more common for very large practices, hospital outpatient departments, ASC and surgical-specialty contracts, and high-volume low-dollar settings (lab billing, certain durable-medical-equipment contracts). The reason for the % model's dominance is incentive alignment: practice owners generally trust a vendor whose revenue scales with theirs more than a vendor paid on submission volume. The % model also handles new-practice ramp-up cleanly (the vendor invoices grow with collections rather than imposing a fixed cost on a not-yet-cash-flowing practice). Per-claim is dominant in settings where claim volume is the operational unit and average claim value is either very low (lab) or very high (surgical specialty).
Are there hidden fees in percentage-of-collections contracts?
Yes, and they cluster around four areas. First, definitional ambiguity in 'net collections' — some contracts apply the percentage to gross collections (before refunds and reversals), which is materially more expensive; require the contract to define net collections as 'cash receipts less refunds and reversals.' Second, charges on aged-A/R recoveries from before the contract started — some vendors apply full percentage on legacy A/R they barely worked; negotiate a lower rate (1-3%) or exclusion for legacy A/R. Third, separate fees for ancillary services (prior authorization, eligibility verification, patient statement printing, credentialing) that may not be in the headline rate. Fourth, implementation/setup fees ($2,000-$15,000) that some vendors invoice separately. Fifth, early-termination penalties tied to multi-year auto-renew clauses; require a 60-90 day termination clause without renewal penalty. Reviewing the contract for these specific areas usually reveals 0.5-1.5 percentage points of effective rate hidden beyond the headline.
Are there hidden fees in per-claim pricing contracts?
Yes, and they tend to be more numerous than in percentage contracts because per-claim vendors unbundle more line items. The most common hidden fees are: resubmission fees on denied claims ($2-$5 per resubmission, which compounds quickly on a high-denial practice); secondary and tertiary claim fees billed separately from the primary submission; eligibility verification fees ($1-$3 per verification, often $50-$300 per month for a small practice); prior authorization fees ($15-$50 per authorization, sometimes priced as a contingent percentage of approved authorization value); patient statement printing and mailing fees ($0.75-$1.50 per statement); patient-pay collection fees (typically 8-15% of collected patient responsibility); and credentialing and enrollment fees ($150-$500 per provider per payer enrollment). Adding these to the headline per-claim rate often produces an effective cost roughly equivalent to a 5-7% of collections rate — but with worse incentive alignment.
Can I negotiate a hybrid pricing model?
Yes, and it is increasingly common for mid-sized practices that want predictability plus incentive alignment. The most common hybrid is a small monthly base fee (typically $1,500-$3,000) plus a smaller percentage of collections (typically 2.5-4%). The base fee covers the vendor's fixed staffing cost, allowing the vendor to accept a lower variable rate. Total cost typically lands close to a pure 5-6% rate but with smoother monthly cash flow on the practice side and bottom-floor revenue protection on the vendor side. Other hybrid structures include: per-claim base plus contingent denial-recovery percentage (vendor charges $4 per submission plus 25-30% of recovered denial dollars, which directly buys denial-work incentive); per-FTE pricing where you essentially rent a dedicated biller for $4,000-$7,000 per month; and tiered % rates that step down at revenue thresholds (6% on first $X, 5% on next $X, 4% above). Hybrids are most useful when standard models do not fit unusual practice economics.
How does pricing model affect denial-rate performance?
The empirical evidence is consistent: percentage-of-collections relationships produce lower denial rates and higher net collection rates than per-claim relationships at comparable practice sizes, primarily because of incentive alignment. Under % pricing, every denial that goes unworked is the vendor's lost revenue too; under per-claim pricing, denials are pure cost to the vendor with no offsetting revenue (unless the contract explicitly compensates denial work). HFMA member literature notes this pattern, and HBMA member surveys document a typical 1.5-3 percentage point net-collection-rate spread between the two models for practices in the under-15-provider range. The implication is not that per-claim pricing is structurally inferior — it is appropriate for practices with already-strong denial performance and predictable volume — but that practices with elevated denial rates should not select per-claim pricing without explicit contractual denial-work SLAs, because the pricing structure does not naturally drive the vendor to capture recoverable revenue.
What KPIs should I tie to the pricing contract regardless of model?
Tie at minimum these five KPIs to contractual SLAs with right-to-renegotiate or terminate on failure: first-pass acceptance rate (target above 95%, MGMA top-quartile benchmark); overall denial rate (target under 5% per HFMA top-quartile); days-in-A/R (target under 35 for primary care, under 45 for specialty); net collection rate (target 95-99% per MGMA top-quartile); and aged-A/R-over-90-days as a percentage of total A/R (target under 15%). The contract should specify reporting cadence (monthly minimum), measurement methodology (which exclusions are allowed; what benchmark source applies), and remediation timing (typically 60-90 days to cure SLA breach before termination right). These KPI clauses turn the pricing model from a pure cost item into a performance contract; without them, even the best-priced contract can underperform without consequence. KPI accountability matters more than headline rate selection.
Does the pricing model affect patient experience?
Indirectly but real, primarily through the patient-statement and patient-collection workflow. Under % of collections, the vendor is incentivized to maximize patient-responsibility collections because patient payments count as collections that earn the vendor's percentage. Vendors typically invest in soft-touch statement workflows, patient-portal payment integrations, and structured payment-plan offerings to maximize patient-pay capture. Under per-claim pricing, patient collections are often a separate line item priced at a contingency percentage (8-15% of collected) or an additional flat fee, which sometimes leads vendors to under-invest in patient-collection workflow because it is a separate revenue line and may not justify the operational investment. The practical effect on patients is usually small but can manifest as more aggressive collection notices in % models (vendor wants the dollars) or less proactive statement engagement in per-claim models without a strong patient-pay add-on. A practice that values patient experience should negotiate explicit patient-collection-workflow standards regardless of pricing model.
Can pricing be renegotiated mid-contract if the model is not working?
Most well-written billing contracts include an annual rate-review clause, often pegged to KPI performance and renewable-with-mutual-consent. Mid-contract pricing changes typically require contract amendment with vendor agreement, but vendors are usually willing to negotiate at the annual review or earlier if the pricing model is materially misaligned with practice economics. Common mid-contract changes include: rate reduction in exchange for contract-term extension, switch from per-claim to % (or vice versa) based on observed claim value and denial-rate data, addition of hybrid base-plus-percentage structure to smooth cash flow, and unbundling or rebundling of ancillary services (prior auth, eligibility, statements). The leverage point is usually the practice's option to not renew or to terminate per the termination clause; a vendor who values the relationship will accept reasonable rate adjustments at review. Practices that do not exercise this leverage tend to overpay in legacy contracts; an annual pricing review against current market rates is a worthwhile operational discipline.
