Mental Health Billing Services
Mental health practices lose money on the clock, on the place of service, and on who actually holds the behavioral health benefit. The line between the 38-to-52-minute psychotherapy code and the 53-minute-and-over one is the specialty's highest-yield audit target: the longer code pays more, payers reserve the right to ask for the record behind it, and a contested session survives on explicit start and stop times rather than narrative duration. Around it sit psychiatry visits that need medication-management and therapy minutes timed as two separate clocks, testing and TMS work that turns on the prior-authorization packet, the telehealth place-of-service split, parity obligations under MHPAEA, Medicare Part B's January 2024 opening to LMFTs and mental health counselors, and the carve-outs where Carelon, Optum Behavioral Health or Magellan adjudicates on rules the medical plan never mentions. We bill against all of it. We verify the behavioral health benefit at eligibility instead of trusting the medical-side response, scrub session times and telehealth coding before submission, route add-on therapy codes only to the provider types each plan recognises, and file the parity-grounded appeal when a concurrent review denies instead of writing the sessions off. It is built for therapy groups, psychiatry practices, and behavioral health organisations across commercial, Medicare and carve-out books.

What do mental health billing services cover, and what do they cost?
Mental health billing is where session time, place of service, provider type and the behavioral health carve-out decide what a claim pays, and we bill practices across all four. We code psychotherapy to the documented start and stop times rather than to rounded duration, keep medication-management minutes and therapy minutes documented as two separate clocks, route add-on therapy codes only to the provider types a plan recognises, and verify at eligibility whether the benefit sits with the medical plan or with a carve-out vendor before the claim goes out. We charge 7.0% of monthly collections for a solo practice and 6.0% for a group of 2 to 15 providers, and enterprise engagements are scoped individually. The percentage is charged on collections received, not on charges submitted, and it is the whole price: no setup fee, no per-claim charge, no software fee, and third-party clearinghouse, postage and payer application fees passed through at cost with no markup, and a 12-month initial term that then runs month-to-month on 60 days' notice with no early-termination penalty. The solo tier carries a monthly minimum, set in your quote rather than published. Worked examples are on the pricing page.
- Published rate: 7.0% of collections solo, 6.0% for 2-15 providers
- Telehealth: POS 10 (patient at home) pays the non-facility rate, POS 02 the facility rate
- MHPAEA parity (29 CFR 2590.712) is the stated basis for appealing concurrent-review denials
- Carve-out routing: Optum, Carelon, Magellan use separate fee schedules

Common Billing Friction in Mental Health
90837 review exposure and the start-stop-time defense
CPT 90837 (53+ minutes) pays more than 90834 (38-52 minutes) — $53 more on the CY2026 Medicare amounts in the code table below — and that gap is why session-length coding draws review. Neither Aetna nor Cigna publishes a session-mix percentage that triggers one, and we do not quote a number. What is published is the mechanism: Cigna's behavioral health provider manual states that the record-keeping practices of selected high-volume practitioners are audited, that those practitioners are identified as they near recredentialing, and that each is asked for blinded copies of three clinical records and scored against an 80 percent performance goal (Cigna Behavioral Health provider manual, read 17 September 2026). A practice whose session mix skews toward the longer code should expect that question sooner than one that does not. So the defense is documentation discipline, not coding strategy: the note must show explicit start time, stop time, and clinical justification for a session that ran past 53 minutes. A note recording only narrative duration ('about an hour') leaves the practice nothing to produce when a 90837 is contested.
E/M plus add-on therapy: why 99214 + 90836 is not 90838
Psychiatrists and psychiatric NPs bill medication-management visits as E/M (99213, 99214, 99215) with the psychotherapy add-ons +90833, +90836, or +90838 layered on. Aetna will not pay add-on therapy codes when the rendering provider is an LCSW, LPC, or LMFT — those codes route to the prescriber only. Two clocks have to be documented separately: the E/M time is medical decision-making and history; the add-on time is psychotherapy time, exclusive of the E/M minutes. Conflating them collapses the claim under NCCI logic and the add-on denies as duplicative service.
MHPAEA non-quantitative treatment limits and concurrent review denials
The Mental Health Parity and Addiction Equity Act of 2008 prohibits payers from applying non-quantitative treatment limitations to mental health benefits more restrictively than to medical/surgical benefits. In practice, payers still impose concurrent-review thresholds at session 8, 12, or 20, and whether a given threshold has a medical/surgical analogue is exactly the question the parity rule makes answerable. So we ask it: the appeal cites 29 CFR 2590.712 and requests the plan's own NQTL comparative analysis for the limitation being applied. We do not publish an overturn rate for those appeals, and you should be skeptical of any billing company that does — what we commit to is that the appeal gets filed instead of the sessions getting written off.
Telehealth after the PHE: POS 02 versus POS 10 and the audio-only carve-out
Post-public-health-emergency rules split telehealth into POS 10 (patient at home, pays at the non-facility rate for behavioral health) and POS 02 (patient at any other location, pays at the facility rate, which is the lower of the two by whatever the practice-expense RVUs for that code differ by). Modifier 95 attaches for synchronous audio-video; modifier 93 attaches for audio-only, which most commercial payers reimburse for established-patient psychotherapy but not for the diagnostic evaluation 90791 or 90792. Submitting 90791 with modifier 93 denies under CARC 4 every time. The legacy GT modifier no longer applies to commercial behavioral health claims.
Behavioral health carve-outs: when Optum, Carelon, or Magellan adjudicates instead of the medical plan
An employer's medical claims may route to UnitedHealthcare while behavioral health claims carve out to Optum Behavioral Health under a separate fee schedule, separate authorization rules, and a separate provider directory. Cigna typically retains behavioral health in-house; Anthem carves out to Carelon (the rebrand of Beacon Health Options). Submitting a behavioral health claim to the medical-plan payer ID returns CARC 109 'not the responsible payer' with no path to redirect — the claim has to be reworked from scratch against the carve-out vendor. Eligibility verification at the 270/271 level must request behavioral health coverage explicitly, because the medical-side response often shows full coverage with no carve-out flag.
Mental Health-Specific Payer Issues We Watch For
UnitedHealthcare
Issue: Sets start and stop time in the service note as a record-review standard for behavioral health, not total session duration alone
Our approach: We build the note template around explicit start and stop times and check for them before the claim goes out, so the record answers the question a review asks
Aetna
Issue: Does not recognize the psychotherapy add-on codes (+90833, +90836, +90838) when billed by non-MD providers (LCSWs, LPCs), limiting add-on billing to psychiatrists and psychologists
Our approach: We verify add-on code eligibility by provider type for each Aetna plan and route add-on claims only for eligible provider categories
Medicare
Issue: Pays telehealth on the place of service, not the modifier: POS 10 (patient at home) pays the non-facility rate for behavioral health while POS 02 (patient anywhere else) pays the facility rate, so a home session coded POS 02 out of habit pays the lower of the two — by whatever the practice-expense RVUs for that code differ by
Our approach: We set the place of service from where the patient actually was and check it on every telehealth claim before submission, and we show practices the per-code difference between the facility and non-facility amounts so the decision is made on real numbers
Cigna
Issue: Limits family therapy (90847) to 20 sessions per year on many plans and does not count couples therapy as a distinct benefit from individual therapy
Our approach: We track family therapy session utilization against plan limits and flag patients approaching their annual maximum to prevent unexpected denials
What We Handle
Psychotherapy time-coding — 90832, 90834, 90837 with audit-survivable notes
CPT 90832 (16-37 min), 90834 (38-52 min), and 90837 (53+ min) coded against documented start-stop times rather than rounded duration. Includes tracking of 90837 frequency across your own book, so the mix is known before a payer asks about it, and note templates built to what a records request calls for: start time, stop time, and the clinical reason the session ran long. Aligned with AMA CPT time-rule guidance (midpoint rule, not the 8-minute rule).
Psychiatry medication management — E/M plus add-on therapy
E/M leveling under the 2021 AMA guidelines (99213, 99214, 99215) paired with add-on psychotherapy codes +90833, +90836, +90838. Separate time documentation for medical decision-making and therapy minutes. Provider-type routing so add-on codes flow only through prescribers (MD, DO, NP, PA), with LCSW/LPC/LMFT visits routed to standalone 90832/90834/90837.
Psychological and neuropsychological testing — 96130 through 96139
Testing-evaluation codes 96130/96131 (psychological) and 96132/96133 (neuropsychological) plus test-administration codes 96136-96139, billed against APA testing guidance and payer-specific medical policies. Covers prior-authorization packets including DSM-5 diagnosis, referral question, and instrument list — assembled to what each plan's own testing policy asks for, before the request goes out.
TMS billing — 90867, 90868, 90869
Repetitive transcranial magnetic stimulation coding for initial treatment with cortical mapping (90867), subsequent delivery (90868), and re-evaluation with cortical remapping (90869). Includes prior-authorization packets demonstrating treatment-resistant depression failure of two or more antidepressants per the FDA-cleared indication and major commercial payer medical policies.
ABA and group therapy — 97151-97155 and 90853
Applied Behavior Analysis coding for assessment (97151), 1:1 treatment by technician (97153), and protocol modification by BCBA (97155), against state Medicaid and commercial autism-mandate policies. Group psychotherapy (90853) and family therapy with patient present (90847) versus without patient (90846), with payer-specific session-limit tracking.
Behavioral health crisis services and same-day billing
Psychiatric crisis codes 90839 (first 60 min) and 90840 (each additional 30 min) billed against same-day admission encounter codes when crisis intervention precedes inpatient admission. Includes same-day E/M plus crisis-code pairing rules that diverge from standard incident-to logic, since most psychiatric services do not qualify for incident-to billing under CMS guidance.

Amounts are CY2026 Medicare national unadjusted non-facility amounts — total non-facility RVUs times the 33.4009 conversion factor in the CMS relative value file — before locality adjustment. Four rows are add-on codes with a ZZZ global indicator: the two psychotherapy add-ons and the two each-additional-unit testing codes, which are paid on top of the base service rather than instead of it. None of these is what a commercial payer pays, and behavioral health carve-outs adjudicate on their own contracted schedules — that is usually where the gap between these figures and a practice's actual collections sits.
Why General Billing Teams Miss Mental Health Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for mental health coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in mental health.
Under-coding high-complexity visits
Mental Health encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for mental health procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn mental health denials quickly.
“Mental health practices lose the most revenue not on denied claims but on sessions billed at the wrong time code and missed E/M add-on opportunities. The line is 53 minutes: a 55-minute session billed as 90834 instead of 90837 gives away the $53 differential every single time. A 45-minute session is 90834 — it was never a 90837, and coding it as one is the mirror-image error.”

Mental Health Billing Terms
- Time-Based Psychotherapy Codes
- CPT codes for individual psychotherapy selected based on session duration: 90832 (16-37 min), 90834 (38-52 min), 90837 (53+ min). Accurate time documentation is essential as coding the wrong time range directly impacts reimbursement.
- Psychotherapy Add-On Codes
- Codes (+90833, +90836, +90838) billed in addition to an E/M service when psychotherapy is provided during the same visit. Common when a psychiatrist provides medication management and therapy in the same session.
- Place of Service (POS) Code
- A two-digit code indicating where the service was provided. POS 11 (office) and POS 10 (telehealth in the patient's home) both pay the Medicare non-facility rate; POS 02 (telehealth anywhere other than the home) pays the lower facility rate.
- Modifier 95 (Synchronous Telehealth)
- Applied to psychotherapy claims delivered via real-time audio-video telehealth to indicate the service was provided remotely. Some payers require this modifier while others use place-of-service codes alone.
- Incident-To Billing
- A billing arrangement where services provided by non-physician providers (LCSWs, LPCs) under physician supervision can be billed under the physician's NPI at the physician rate. Requires specific supervision and documentation criteria.
- Diagnostic Evaluation (90791)
- A full psychiatric evaluation including history, mental status examination, and treatment recommendations. Typically performed at intake and billed once per treatment episode. Does not include psychological testing.

Request ReviewHow much do mental health billers charge?
MedPrecision charges 7.0% of monthly collections for a solo mental health practice and 6.0% for a group of 2 to 15 providers, with enterprise engagements scoped individually. The percentage is charged on collections received, not on charges submitted, so above the solo tier's monthly minimum an unpaid claim costs you nothing in fees. A practice collecting $40,000 a month pays $2,800 at the solo rate and $2,400 at the group rate. That percentage is the whole price: no setup or implementation fee, no per-claim charge, no software fee, and third-party clearinghouse, postage and payer application fees passed through at cost with no markup. The agreement runs a 12-month initial term and then month-to-month, with 60 days' written notice either way and no early-termination penalty, and EMR/EHR integration included. The solo tier's monthly minimum is set in your quote and Service Agreement rather than published here, because it is scoped to the practice — ask for it in writing before you sign and read it alongside the percentage. On a mental health book the rate covers eligibility checks that ask for the behavioral health benefit specifically instead of accepting the medical-side response, session-time and telehealth scrubbing before submission, add-on code routing by provider type, prior-authorization packets for testing and TMS, parity-grounded appeals on concurrent-review denials, and monthly reporting. Most billing companies publish no rate at all, so compare on what a percentage includes rather than on the percentage alone. Full terms, worked examples and the flat-fee packages are on the pricing page.
How do you handle billing for different psychotherapy session lengths?
Time-based psychotherapy CPT codes follow strict AMA CPT-defined duration ranges, and the billed code must match the documented face-to-face time spent with the patient. The three primary individual psychotherapy codes are: CPT 90832 for 16-37 minutes (Medicare reimbursement approximately $86), CPT 90834 for 38-52 minutes (approximately $114), and CPT 90837 for 53+ minutes (approximately $167). The CMS 8-minute rule for timed therapy codes does not apply to psychotherapy. The code is selected from the total face-to-face psychotherapy time, and the published ranges are 16-37 minutes for 90832, 38-52 minutes for 90834 and 53 minutes or more for 90837 (American Psychological Association Services, psychotherapy coding guidance, verified September 17, 2026). A 45-minute session therefore falls inside 90834; it does not become a 90837 by rounding up. We document to the stricter standard on every psychotherapy claim — explicit start and stop times rather than a narrative duration — because that is what makes the 53-minute floor verifiable if the 90834 versus 90837 differential is ever questioned. The arithmetic is worth doing once: a practice that bills 90834 on five sessions a week that actually ran 53 minutes or longer gives up $53 x 5 x 52 = $13,780 a year in reimbursement its own documentation supports. That is a multiplication on the CY2026 Medicare amounts above, not a benchmark — we have not seen a published figure for how often it happens and do not quote one. The threshold arithmetic, the 2026 CMS PFS rates and the documentation that survives an audit are worked through in 90834 vs 90837: the 38–52 vs 53+ minute rule.
Can you manage billing for both in-person and telehealth mental health sessions?
Mental health telehealth billing requires three distinct elements aligned with each payer's policy: place-of-service (POS) codes, modifiers, and parity-rate verification. Per CMS guidance effective 2024, POS 10 indicates telehealth in the patient's home and POS 02 indicates telehealth provided in any other location, with the two codes triggering different reimbursement rates. Modifier 95 (synchronous telemedicine via real-time audio-video) is required by most commercial payers, while Medicare retains modifier GT for some scenarios under transitional rules. Audio-only telehealth uses modifier 93. State telehealth laws differ on whether they require coverage parity, payment parity, or neither, so the governing statute has to be read for each state a practice bills in rather than assumed from a neighbouring one. Medicare is a separate question again: for most settings post-public-health-emergency it pays telehealth at the facility rate rather than the non-facility rate, and how much lower that is depends on the practice-expense RVUs for the code. We code from each payer's own telehealth policy rather than from a general rule, because the POS and modifier combination a payer accepts is the one written in its policy.
What mental health services require prior authorization?
Mental health services requiring prior authorization vary by payer but consistently include four categories per the major commercial payer medical policies (UnitedHealthcare, Aetna, Cigna, BCBS): (1) psychological and neuropsychological testing using CPT codes 96130-96139 (test administration and interpretation), which typically require pre-auth with diagnostic justification; (2) intensive outpatient programs (IOP) and partial hospitalization programs (PHP) under HCPCS H0015 and H0035, requiring concurrent authorization based on Level of Care Utilization System (LOCUS) or American Society of Addiction Medicine (ASAM) criteria; (3) applied behavior analysis (ABA) services under CPT 97151-97158 for autism spectrum disorders, which require diagnostic confirmation and a treatment plan; and (4) extended psychotherapy beyond plan-defined session limits, with many plans authorizing 8-12 initial sessions before requiring concurrent review. The Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) prohibits more restrictive prior authorization standards for mental health than for medical/surgical benefits, but enforcement gaps persist. We assemble the authorization packet — DSM-5 diagnosis, treatment goals and progress measures — before the request goes out, and track it to a decision rather than reworking it after a denial.
How do you reduce claim denials for mental health practices?
Four denial drivers do most of the damage on a behavioral health book. We do not publish a share for them: MGMA's benchmark values are licensed rather than public, and we have found no free primary source that cuts denial causes by specialty. The four are: (1) eligibility and benefit denials (CARC 27, 31), prevented through real-time 270/271 eligibility verification before each session including verification of mental health benefit limits, copay, and behavioral health carve-out vendors such as Optum Behavioral Health or Magellan; (2) time-based coding mismatches between documented session duration and billed CPT 90832/90834/90837, prevented by claim scrubbing rules that flag discrepancies before submission; (3) telehealth POS and modifier errors, which is why telehealth claims get a place-of-service and modifier check of their own before submission rather than riding the general scrub; and (4) authorization-related denials (CARC 197) for psychological testing and IOP/PHP. When a mental health practice's denial rate is elevated, those four are where we look first, and the work sits at the front of the claim rather than in appeals at the back of it. We report the denial rate we measure on your own book monthly; we do not publish a target for it.
