A clinic that sees dozens of patients a day can lose real revenue to small, repeated unit errors and expired authorizations.
Why specialized physical therapy billing matters
PT billing services must understand timed vs untimed codes, therapy modifiers, plan-of-care requirements and visit tracking — details general billers often miss.

Physical Therapy coding and claims management
Examples of the codes and rules our team works with every day:
97161–97163
PT evaluations by complexity (low, moderate, high); 97164 for re-evaluation.
97110 / 97112 / 97140 / 97530
Common timed treatment codes billed in 15-minute units.
8-minute rule
Medicare totals timed minutes to determine units; many commercial payers use different rules.
GP / KX / CQ
GP identifies PT services; KX attests medical necessity above the Medicare threshold; CQ marks services by PTAs, which may be paid at a reduced rate.
Codes are examples, not coding advice. We apply current CPT®, ICD-10-CM, HCPCS and payer policy to each claim.
Common physical therapy billing challenges and claim denials
Unit miscalculation
Applying the wrong unit rule for a payer leads to underbilling or overbilling.
Visit caps and authorizations
Treatment past an authorized visit count is a common denial.
Plan of care certification
Medicare requires a certified plan of care; missing signatures cause denials.
Medicare threshold
Services above the annual KX threshold need documented medical necessity.
How our RCM services help physical therapy practices
Our physical therapy revenue cycle management tracks authorizations and visit counts per patient so treatment never outruns approval.
Insurance eligibility and benefits verification
We verify PT benefits, visit limits, copays and authorization rules before the initial evaluation. Learn about verification.
Payment posting and accounts receivable
We post payments per unit and catch underpayments on timed codes. Unpaid claims are followed up through our A/R management process.
Denial management and appeals
We correct modifier, unit and authorization denials quickly to protect weekly visit revenue. See our denial management services.
Credentialing and enrollment
We credential PTs and enroll PTAs where payers allow, plus group enrollments for multi-location clinics. Insurance credentialing is $150 per payer.
