Medical Billing for Physical Therapy Clinics
Physical therapy claims depend on units, minutes, and limits. A single mis-set unit total can turn a clean claim into a denial, and a missed visit limit can turn a finished plan of care into a write-off. Guardian helps therapy clinics keep those counts accurate.

Minutes, units, and the eight-minute rule
Timed codes are the most frequent source of therapy denials and the easiest to fix systematically. When treatment time is recorded accurately and units are calculated consistently, most of these denials stop before they start.
The second layer is plan-of-care and certification timing. Claims submitted after a certification expires are denied regardless of clinical need, so the tracker needs to surface expiring certifications before the visit, not after the claim.
- Timed-code unit calculation and total-time documentation
- Visit limits and remaining-benefit tracking per payer
- Plan-of-care certification and recertification dates
- Modifier use for assistant-provided services
Keeping the schedule full and the ledger current
Therapy clinics feel billing pain twice: unpaid claims and uncollected patient responsibility. Deductibles and coinsurance are predictable in January and easy to forget in March.
We combine claim follow-up with a simple view of patient balances, so front-desk conversations can happen while the patient is still in the building rather than through a series of statements.
Measures worth reviewing
Numbers only help if they are defined the same way each month. These are the four we would look at first for a physical therapy practice.
- Denied units tied to documentation or timing
- Authorization and certification expirations ahead of service
- Average days in A/R by payer
- Patient responsibility collected at the time of service
