Medical Billing for Physical Therapy
Our physical therapy billing services treat PT billing as what it is: arithmetic under audit. Timed codes, the 8-minute rule, multiple-procedure reductions, and Medicare's therapy threshold with KX modifier requirements mean every visit's unit math has to be right, and every plan of care has to be certified on time or the payer takes the visit back. We run the unit calculations, track certifications and thresholds per patient, and keep the modifiers straight, so your clinic's front desk can stop doing billing between patients and your denials stop eating visits you already delivered.
8-minute rule unit calculation across timed codes (97110, 97112, 97140) done correctly on every date of service
Medicare therapy threshold tracking with KX modifier application and documentation to support continued care
Plan-of-care certification and recertification tracking so claims aren't denied for missing physician signatures
CCI edit and modifier 59/X handling on common PT code pairs, applied only when documentation supports it
GP therapy modifier and payer-specific rules applied automatically at claim scrubbing
Key CPT Codes in Physical Therapy Billing
The codes that drive most of the revenue in this specialty, and what has to be right on each one.
| Code | Service | Billing Note |
|---|---|---|
| 97161-97163 | PT evaluation (low / moderate / high complexity) | Untimed. Complexity level must match documented clinical presentation; payers watch for habitual high-complexity coding. |
| 97110 | Therapeutic exercise | Timed. The most-billed PT code; units follow the 8-minute rule across the visit's total timed minutes. |
| 97112 | Neuromuscular re-education | Timed. Document the specific deficit (balance, proprioception, coordination) being retrained. |
| 97140 | Manual therapy | Timed. Hits CCI edits with evaluation codes on the same visit; needs modifier 59/X and separate documentation when appropriate. |
| 97530 | Therapeutic activities | Timed. Functional, dynamic activities; notes must distinguish it from 97110 or payers recode the claim downward. |
| 97014 / G0283 | Electrical stimulation (unattended) | Untimed modality. Medicare requires G0283 instead of 97014; billing the wrong one is an automatic rejection. |
| KX modifier | Medicare therapy threshold attestation | Required once a patient's annual therapy spend passes the threshold. Applied with supporting documentation, never blanket-applied. |
| GP modifier | Services under a PT plan of care | Required on every Medicare PT claim line. Missing GP is one of the most common and most preventable PT rejections. |
Top Physical Therapy Denials We Prevent
Unit count doesn't match the 8-minute rule
How we prevent it: We recalculate billable units from documented timed minutes on every date of service before submission, so claims are never over- or under-unitized.
Plan of care not certified or recertification lapsed
How we prevent it: Certification dates are tracked per patient with alerts before the 90-day recert window closes, so no visit falls in an uncertified gap.
Therapy threshold exceeded without KX modifier
How we prevent it: Each Medicare patient's accrual toward the annual threshold is tracked, and KX is applied with documentation exactly when it becomes required.
CCI edit pair billed without a valid modifier
How we prevent it: Common PT pairs (like 97140 with an evaluation) are checked against current CCI edits, and modifier 59/X is applied only when the documentation supports distinct services.
Missing GP modifier on Medicare claims
How we prevent it: The GP modifier is enforced at claim scrubbing on every Medicare PT line, so this rejection simply doesn't occur.
Physical Therapy Billing FAQs
For Medicare, total timed-code minutes across the visit determine billable units (8 to 22 minutes is 1 unit, 23 to 37 is 2, and so on), then units are distributed to the services with the most minutes. Getting it wrong in either direction is a problem: under-billing loses revenue, over-billing is an audit finding.
Beyond the annual threshold, claims need the KX modifier attesting medical necessity, with documentation to back it. Above the higher targeted-review threshold, records may be pulled. We track each Medicare patient's accrual so KX is applied when, and only when, it's appropriate.
Medicare requires the physician-certified plan of care within 30 days and recertification at least every 90 days. If certifications lapse, every visit in the gap is denialable. It's purely administrative revenue loss, exactly the kind a disciplined billing workflow eliminates.
PT billing is typically priced at 4% to 8% of collections, reflecting the specialty's smaller average claim size and higher per-visit billing workload. Most clinics find the fee pays for itself in recovered units alone: correct 8-minute rule math and clean modifier use routinely lift collections more than the service costs.
Yes. Hybrid clinics need clean separation between insurance claims and cash services, correct use of ABNs for non-covered Medicare care, and self-pay pricing that doesn't conflict with payer contracts. We run the insurance side and keep the cash side compliant.
Yes. Aged PT claims usually fail for documentation-fixable reasons: missing certifications, unit corrections, or modifier issues that can be corrected and resubmitted before timely-filing deadlines pass. We triage old AR by dollar value and deadline, recover what's winnable, and tell you plainly what isn't.
