Physical therapy billing is arithmetic with consequences. Timed and untimed codes appear in the same visit, units are calculated from documented treatment minutes, therapy modifiers have to be applied under payer-specific rules, plan-of-care certification has to be current, and benefit limits run down visit by visit.
Physical therapy billing turns on arithmetic: units calculated from documented treatment time, visits that mix timed and untimed codes, therapy modifiers applied under payer policy, plan-of-care certification kept current, and benefit limits tracked as visits are delivered.
One wrong unit calculation is a small error. The same wrong calculation repeated across a busy clinic for a quarter is a systematic problem that shows up as a denial pattern nobody can explain.
Rev Cura builds unit checking and certification tracking into the daily workflow, so the arithmetic is verified at claim creation rather than reconstructed during an appeal.
Units are calculated from documented treatment time under the rules the payer applies, including the minute-counting convention Medicare uses for timed codes. Visits that mix timed and untimed services are checked specifically, because that is where the arithmetic usually goes wrong.
Physical therapy evaluations are tiered by complexity, and the tier billed has to match what the evaluation documents. We check the tier against the note rather than defaulting to the middle.
Certification and recertification dates are tracked so claims are not submitted against a plan of care that has lapsed — a denial reason that is entirely administrative and entirely avoidable.
Discipline modifiers and the modifiers signalling distinct services or continued medical necessity are applied under current payer policy rather than by habit, and reviewed when they start attracting denials.
Visit limits are established at verification and tracked as visits are delivered. Where a payer applies an annual threshold above which additional documentation or a modifier is required, that point is flagged before it is crossed.
Where progress notes or daily notes are not evidencing skilled therapy for the units billed, the pattern goes back to the treating therapist as specific feedback rather than a general reminder.
A visit combining timed exercise with an untimed modality is the single most common place PT units are billed incorrectly, in both directions.
Certification lapses quietly. The therapy continues, the claims go out, and the denials arrive in a batch weeks later covering treatment that has already been delivered.
Because modifier use tends to be applied consistently by a clinic, a modifier error is rarely isolated — it affects every claim of that type until someone traces it.
Visit caps run down silently. Without tracking, the practice finds out at the denial, by which point the patient has already been treated.
Payers look for evidence that the service required the skills of a therapist. Notes that read as supervised exercise invite denial and, on review, recoupment.
The metrics that matter in this specialty, agreed at the start and reported on a fixed rhythm.
What we need from your therapists is treatment time recorded clearly and notes that describe the skilled component of the service. Both are things good clinical documentation already does; the billing simply depends on them being consistent.
Unit rules are payer-specific. The convention one payer applies to timed codes is not automatically the convention another applies, so we configure the check per payer rather than applying one national rule to everything.
We do not tell therapists how much treatment to provide, and we do not adjust units to reach a target. Where the documented time and the billed units do not agree, the answer is a query, not a rounded number.
Yes. Unit calculation is checked at claim creation against the rules the relevant payer applies, rather than trusted to whatever was entered at the front end.
Yes. Certification and recertification dates are tracked so claims are not filed against a lapsed plan of care.
Yes, where those services sit alongside physical therapy in the same practice. Each discipline has its own modifier and documentation expectations.
It is flagged before the limit is reached so the practice can have the conversation with the patient in advance — about continued coverage, self-pay, or whether additional documentation supports continued care.
We review it for billing sufficiency, not clinical quality. Where the note does not evidence what is being billed, we query it and feed the pattern back to the therapist.
Yes, and it is usually one of the clearest early wins. Inconsistency between sites makes every denial pattern harder to diagnose than it needs to be.
