Why Chiropractic Practices Choose Atlas Billers

Chiropractic billing is uniquely challenging because Medicare and many commercial payers impose strict limitations on covered services. Medicare only covers spinal manipulation (98940–98942) for documented subluxation, requires the AT modifier to distinguish active treatment from maintenance care, and demands specific subluxation documentation including the PART criteria (Pain, Asymmetry, Range of motion, Tissue/tone changes). General billing companies rarely understand these nuances, leading to high denial rates.

Atlas Billers provides chiropractic-specialized coders who know the difference between active and maintenance treatment phases, understand payer-specific policies on adjunctive therapies like electrical stimulation and therapeutic exercise, and ensure every manipulation claim includes the documentation elements required for payment. We help your practice bill confidently while staying fully compliant.

Common Chiropractic Billing Challenges

Medicare AT Modifier Requirements and Active Treatment Documentation

Medicare requires the AT modifier on every chiropractic manipulation claim to indicate active treatment. Claims submitted without this modifier, or with insufficient documentation to support active treatment goals, are automatically denied.

Spinal Manipulation Coding with Proper Subluxation Documentation

Codes 98940 (1-2 spinal regions), 98941 (3-4 regions), and 98942 (5 regions) require documented subluxation findings. The initial visit must include a subluxation statement with specific spinal level identification, or Medicare will deny the entire treatment episode.

Maintenance Therapy vs. Active Treatment Distinction

One of the most contentious areas in chiropractic billing is determining when a patient transitions from active corrective care to maintenance therapy. Medicare does not cover maintenance care, and improper billing of maintenance visits as active treatment creates significant audit liability.

X-Ray Medical Necessity and Frequency Limitations

While chiropractic X-rays (72020, 72040–72114) can support subluxation documentation, many payers limit frequency and require clear medical necessity beyond routine use. Over-ordering imaging leads to denials and potential audit exposure.
