Physical Therapy Billing Services
Physical therapy billing services cover benefit verification, timed-code unit calculation, modifiers, plan-of-care tracking, claim submission and denial work for outpatient PT clinics and rehab groups. ClaimCarePro provides physical therapy billing services with payer credentialing included.
The rule every PT claim is paid by
The 8-minute rule, applied correctly to each payer
Medicare pays timed codes on total treatment minutes. Many commercial plans count each code separately. We apply the method each payer actually uses, so units are neither inflated nor given away.
1 unit
8–22 min
2 units
23–37 min
3 units
38–52 min
4 units
53–67 min
Total timed minutes across all timed codes in the visit, Medicare method. Untimed codes are billed once regardless of minutes. The annual KX threshold dollar amount is published by CMS each January; we update it the day it changes.
PT billing cheat sheet
The codes and modifiers we bill every day
This is the working set for an outpatient PT claim. Which combinations pay, and at what rate, differs by payer — that is the work.
Evaluations
97161 · 97162 · 97163 (low / moderate / high complexity) · 97164 re-evaluation
Timed treatment codes (15-min units)
97110 therapeutic exercise · 97112 neuromuscular re-education · 97140 manual therapy · 97530 therapeutic activities · 97535 self-care training · 97116 gait training
Untimed codes (once per visit)
97012 mechanical traction · 97014 unattended e-stim (G0283 for Medicare) · 97035 ultrasound · 97010 hot/cold packs (bundled by most payers)
Modifiers
GP plan of care · KX above the annual threshold · CQ for PTA-delivered services · 59 / X-modifiers only for genuinely distinct services
What our physical therapy billing services include
Timed-code unit calculation
Units for 97110, 97112, 97140, 97530 and 97535 computed from total timed minutes under the 8-minute rule, with untimed codes (97012, 97014 / G0283, 97035) billed once per session, so no unit is over- or under-billed.
Evaluations and plan-of-care compliance
Complexity-tiered evaluations (97161 / 97162 / 97163) and re-evaluations (97164) coded to the documentation; Medicare plan-of-care certification and progress-note cadence tracked so claims are not denied on paperwork.
Modifiers: GP, KX, CQ and 59
GP on every PT plan-of-care service, KX once the annual threshold is crossed with medical necessity documented, CQ when a PTA delivers the service, and 59 only where NCCI genuinely allows a distinct service.
Authorizations and visit limits
Commercial visit caps, Medicaid prior authorizations and workers' compensation approvals tracked per patient, with remaining visits visible to the front desk before the next appointment is booked.
Denials, MPPR and underpayments
Multiple-procedure payment reductions reconciled line by line, bundling denials appealed with the note, and workers' comp and auto-injury fee-schedule underpayments pursued.
Reporting by therapist and payer
Units billed vs paid, average reimbursement per visit, denial reasons and days in A/R by therapist, location and payer.
Where PT revenue leaks — and how we stop it
The 8-minute rule
Medicare pays timed codes by total treatment minutes: 8–22 minutes is one unit, 23–37 two, 38–52 three, 53–67 four. Commercial payers may count each code separately instead. Billing the wrong method on the wrong payer is the most common PT overpayment and underpayment at once.
KX threshold and medical necessity
Once a patient's PT and speech-therapy spend passes the annual threshold CMS publishes each January, every claim needs the KX modifier and documentation that continued care is medically necessary. Claims without it deny; claims with it and thin notes get audited.
PTA services and the CQ modifier
Services furnished in whole or in part by a physical therapist assistant are billed with CQ and paid at a reduced rate by Medicare. Missing the modifier is a compliance problem; applying it when the PT did the work gives revenue away.
NCCI edits and the 59 modifier
97140 with 97530, or an evaluation with treatment on the same day, hit bundling edits. Modifier 59 unlocks payment only when the services were distinct and the note proves it.
Plan-of-care certification
Medicare requires the plan of care to be certified by the referring physician within 30 days and recertified when it changes or expires. A signature that never came back turns a month of visits into a write-off.
Workers' comp and auto-injury schedules
Workers' compensation and personal-injury payers use their own fee schedules and authorization rules. In Florida, PIP claims are priced against the §627.736 schedule and a $10,000 benefit that exhausts fast.

Billing and credentialing together
A new therapist should bill from week one
Medicare enrollment, commercial panels and Medicaid applications are handled by the same team that bills the visits — so nothing is delivered before the effective date without a plan for it.
- Published pricing — flat per-provider fees on our credentialing services page; no quotes, no surprises.
- Weekly payer follow-up — every application chased until the effective date is in writing.
- Claims held, not lost — visits before the effective date are held and released the day enrollment lands.
