Specialty - Chiropractic
Chiropractic billing is audit-prone by default. Generic AI makes it worse.
Chiropractic is one of the highest-risk billing specialties in healthcare: CMS-restricted coverage, region-counted CMT codes, an unforgiving AT / maintenance line, ABN workflows, and a patient mix that spans Medicare, commercial, workers' comp, and auto liability. Linx is built for clinics that need every one of those rules applied on every visit, not just the easy ones.
Why Chiropractic Coding Resists Generic AI
Six rule systems run at the same time on every chiropractic claim: region counting, PART documentation, AT vs. maintenance, ABN state, dual-diagnosis pairing, and payer sequencing. A generic coder that misses any one silently converts clean visits into denials or audit exposure.
Spinal region miscounting on 98940 / 98941 / 98942
CMS recognizes five spinal regions (cervical, thoracic, lumbar, sacral, pelvic). 98940 covers 1 to 2 regions, 98941 covers 3 to 4, 98942 covers all 5. Region counting is the single most audited element in chiropractic CMT coding. Generic AI that reads the note without an anatomy map either upcodes (audit and repayment) or undercodes (silent revenue loss).
Medicare PART documentation gaps
Medicare requires subluxation documented via the PART system: Pain/tenderness, Asymmetry/misalignment, Range of motion abnormality, Tissue/tone changes. Missing any of the four turns a clinically legitimate visit into a denied claim. Linx parses PART findings from the note and blocks submission when they are incomplete.
AT modifier: active vs. maintenance therapy
Medicare only pays chiropractic when treatment is corrective. AT is required on 98940 to 98942 for active care. Missing AT means automatic denial as maintenance. Applying AT to a patient in maintenance care is a fraud exposure. Linx keys AT off the treatment plan and progress, not off a fixed template.
Medicare's narrow coverage envelope and ABN / GA workflow
Medicare covers only manual spinal manipulation for subluxation. Modalities, therapy codes, and E/M visits billed to Medicare are non-covered by statute. Providers must obtain a signed ABN, apply GA (or GY for statutory), and keep the ABN on file. Linx enforces the ABN check before a non-covered line ever leaves the system.
Multi-payer sequencing: WC, MVA / PIP, MedPay, PPO, commercial
Chiropractic patient mix routinely spans workers' comp, auto liability, MedPay, attorney liens, and commercial insurance. Each has different billing priority, different forms, and different balance-billing rules. Linx routes each claim through the right payer sequence instead of dropping every visit into one billing queue.
Dual diagnosis and payer-specific timely filing
Medicare requires subluxation as the primary ICD-10 and the neuromusculoskeletal condition as secondary, with date of initial treatment on file. Filing windows vary dramatically: Medicare 12 months, many BCBS plans 90 to 180 days, Medicaid by state. Linx enforces the dx pair and tracks per-payer filing clocks on every open claim.
Real Chiropractic Visits, Coded Correctly
The scenarios that quietly cost chiropractic practices revenue and trigger the majority of audits.
98942-AT, M99.01 (primary subluxation) + M54.5 (secondary)Linx counts regions from the exam and treatment note, applies AT because the plan of care is corrective, and pairs subluxation as the primary diagnosis with the neuromusculoskeletal secondary Medicare requires.
98941-GA (ABN on file)Linx flags the visit as maintenance based on progress trend, requires an ABN before submission, applies GA, and posts the expected patient responsibility instead of routing to Medicare as active care.
98941-AT, 99213-25Linx confirms the E/M note documents a distinct problem beyond the pre-adjustment assessment, attaches modifier 25 to the E/M, and prevents the common denial pattern of unsupported same-day E/M with CMT.
Claim routed to auto carrier first, health plan queued for balanceLinx reads the accident date and liability data, sequences billing to the auto carrier with the claim number, and holds the commercial submission until the primary EOB posts to avoid duplicate filing and lien conflicts.
Chiropractic Modifier Reference
Linx applies each of these based on plan of care status, ABN state, NCCI edits, and the payer on file.
Built for the Chiropractic Workflow
From signed SOAP note to clean claim, with PART enforcement, region-based CMT selection, and payer-aware routing baked in.
SOAP note, PART findings, and regions ingested
Linx pulls the daily SOAP note, PART exam findings, spinal regions treated, treatment plan status, and payer/liability data from ChiroTouch, Jane, ChiroFusion, Genesis, or your EHR.
AI applies chiropractic-specific logic
Region count drives CMT code (98940 / 98941 / 98942). AT / GA / GY / 25 / 59 modifier stack applied from plan status, ABN state, and NCCI edits. Dual dx paired. Payer sequencing resolved.
Clean claim to the right payer, in the right order
Each claim is routed through the correct payer path (Medicare, commercial, workers' comp, auto / PIP / MedPay) with a full audit trail back to the SOAP note and PART findings.
Calculate Your Chiropractic Coding ROI
High-volume chiropractic practices typically recover a full biller's worth of capacity within the first quarter, plus a measurable revenue lift from correct region counting, AT enforcement, and payer sequencing.

Chiropractic Coding FAQ
How does Linx choose between 98940, 98941, and 98942?
Linx maps the spinal regions treated in the SOAP note against CMS's five-region model (cervical, thoracic, lumbar, sacral, pelvic) and selects 98940 for 1 to 2 regions, 98941 for 3 to 4, and 98942 for all 5. Coverage of each region must be supported by exam findings and treatment detail in the note before the code is assigned.
How does Linx enforce the AT vs. maintenance distinction on Medicare?
Linx tracks each patient's treatment plan status, progress trend, and functional outcome measures over time. When care is corrective and progress is documented, AT is applied. When the record shows plateaued progress or the plan of care shifts to maintenance, AT is removed and the workflow routes to ABN / GA instead of billing Medicare as active care.
Does Linx handle the ABN and GA / GY workflow for non-covered services?
Yes. Before a non-covered service is submitted for a Medicare patient, Linx checks for a signed ABN in the record. If present, GA is applied. If the service is statutorily excluded, GY is applied so the denial EOB can move to a secondary payer. If no ABN is on file, the claim is held and a task is opened at the front desk.
How does Linx sequence claims for MVA / PIP and workers' comp patients?
Linx reads the accident date, injury type, employer/carrier data, and any attorney lien on the account. Workers' comp is routed with the employer claim number and separate WC forms. MVA visits are sequenced to auto liability, PIP, or MedPay first per state rules, with commercial insurance queued to receive the balance after the primary EOB posts.
