Chiropractic Billing Services
Chiropractic billing requires specialized knowledge of spinal manipulation coding, AT modifier requirements for Medicare, and the distinction between active treatment and maintenance care. Payers frequently deny chiropractic claims for lack of medical necessity or exceeding visit limits, making documentation and coding accuracy critical. Our chiropractic billing experts help practices maintain healthy cash flow while navigating payer-specific requirements.

Common Billing Friction in Chiropractic
AT Modifier and Medicare Compliance
Medicare requires the AT modifier on chiropractic manipulation claims to indicate active treatment versus maintenance care. Omitting the AT modifier results in automatic denial, while improper use triggers audit scrutiny for maintenance therapy billing.
Medical Necessity Documentation for Ongoing Care
Payers frequently challenge the medical necessity of ongoing chiropractic treatment, requiring objective functional improvement documentation at regular intervals to justify continued care beyond initial visit allowances.
Ancillary Service Bundling Rules
Chiropractic offices often provide adjunctive therapies (electrical stimulation, ultrasound, therapeutic exercise) that payers may bundle with manipulation codes, requiring proper modifier usage and separate documentation.
Visit Limit Management
Many commercial plans impose annual visit limits for chiropractic services, and exceeding these limits without authorization results in patient balance billing complications and denied claims.
Chiropractic-Specific Payer Issues We Watch For
Medicare
Issue: Only covers manual spinal manipulation (98940-98943) with AT modifier — all other chiropractic services including exams, X-rays, and adjunctive therapies are excluded from coverage
Our approach: We ensure every Medicare claim includes only covered CMT codes with the AT modifier and route non-covered services to patient responsibility or secondary insurance
UnitedHealthcare
Issue: Imposes visit limits as low as 20 visits per year on many plans and denies claims without explicit notification when the limit is reached
Our approach: We track visit utilization against plan limits in real time and alert providers when patients approach their annual maximum to discuss continued care options
BCBS
Issue: Frequently bundles 97140 (manual therapy) with 98941 (CMT) when performed on the same date, denying manual therapy as inclusive of the manipulation
Our approach: We document manual therapy techniques as distinct from CMT with separate body regions, apply modifier 59, and include specific treatment time documentation
Cigna
Issue: Requires functional outcome measures (FOTO or equivalent) at specified intervals to continue authorizing chiropractic treatment beyond initial visit allowance
Our approach: We integrate functional outcome tracking into the documentation workflow and submit outcome data with re-authorization requests at the required intervals
What We Handle
Spinal Manipulation Coding
Accurate coding of CMT services (98940-98943) based on the number of spinal regions treated per visit.
AT Modifier Compliance
Proper application of the AT modifier for Medicare claims to distinguish active treatment from maintenance care.
Ancillary Service Billing
Separate billing of adjunctive therapies with correct modifiers to prevent bundling with manipulation codes.
Visit Limit Tracking
Monitoring annual visit utilization against plan limits and alerting providers before limits are reached.
Auto Accident and PI Billing
Managing personal injury and auto accident claim billing with proper lien documentation and attorney coordination.

Real Results
The Challenge
A 4-provider chiropractic practice was experiencing 35% denial rates on Medicare claims due to AT modifier issues and losing ancillary therapy revenue to bundling with manipulation codes
Our Approach
We implemented AT modifier compliance protocols for every Medicare claim, restructured ancillary service documentation to support separate billing, and appealed 6 months of incorrectly denied claims
Key Outcomes
- check_circle Medicare denial rate dropped from 35% to 4%
- check_circle Ancillary service revenue increased by $3,200 per month
- check_circle Recovered $28,400 in previously denied claims through appeals
- check_circle Average reimbursement per visit increased by $18
“Our Medicare denials were out of control before MedPrecision. They fixed the AT modifier problem and we saw the impact in our very first month.”
Why General Billing Teams Miss Chiropractic Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for chiropractic 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 chiropractic.
Under-coding high-complexity visits
Chiropractic 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 chiropractic procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn chiropractic denials quickly.
“The AT modifier is not optional on Medicare chiropractic claims — it is the difference between getting paid and getting denied. But the bigger issue is the ancillary revenue that chiropractors leave behind because they assume everything gets bundled.”

Chiropractic Billing Terms
- AT Modifier
- A Medicare-required modifier appended to chiropractic manipulation codes (98940-98943) to indicate the service is active treatment for a documented subluxation, not maintenance care. Claims without the AT modifier are automatically denied.
- Subluxation Documentation
- Medicare requires documentation of spinal subluxation by X-ray or physical examination findings including asymmetry, range of motion abnormality, tissue/tone changes, or misalignment (PART criteria). This documentation is the basis for chiropractic medical necessity.
- Maintenance Therapy
- Chiropractic treatment that maintains or prevents deterioration of a chronic condition rather than actively treating an acute episode. Medicare does not cover maintenance care, and commercial payers may have limited or no coverage.
- CMT (Chiropractic Manipulative Treatment)
- Manual therapy applied to the spine to correct subluxations. Coded based on the number of spinal regions treated: 98940 (1-2 regions), 98941 (3-4 regions), 98942 (5 regions). The most commonly billed chiropractic procedure.
- Modifier 25
- Used to indicate a significant, separately identifiable E/M service performed on the same day as a procedure. In chiropractic, allows billing an office visit in addition to manipulation when documentation supports a separate evaluation.
- Functional Outcome Measures
- Standardized tools (Oswestry, NDI, FOTO) used to document objective patient improvement. Many payers require periodic outcome measurements to justify continued chiropractic treatment authorization.

Request Review arrow_forwardDoes Medicare cover chiropractic services?
Medicare covers manual spinal manipulation (CMT) for documented subluxation when the AT modifier confirms active treatment. Medicare does not cover X-rays, exams, or adjunctive therapies provided by chiropractors. We ensure every Medicare claim includes the AT modifier and proper subluxation documentation.
How do you handle denied chiropractic claims for medical necessity?
We appeal medical necessity denials with objective documentation including functional outcome measures, pain scales, and range-of-motion improvements. We also work with providers to strengthen clinical notes that demonstrate ongoing improvement and treatment necessity.
Can you bill for chiropractic exams and manipulation on the same day?
Yes, with most commercial payers. The exam (99201-99215) and manipulation (98940-98943) are separate services when properly documented. We apply modifier 25 to the E/M code to indicate a separately identifiable service and ensure documentation supports both components.
