Physical therapy billing software is judged on three things a PT clinic bills that most specialties do not: timed units counted under the 8-minute rule from the minutes across the visit, a plan of care that has to be certified and recertified for the claim to stand, and a progress note cadence the payer expects the documentation to show. A one-to-five-therapist clinic bills many small claims to a few payers, so the unit count and the denial rate decide the month. This page sets out what the software has to carry for a PT claim, the two places PT claims fail, what a clinic asks a vendor to show on its own claims, and what the claims register keeps beside the software.
What the software has to carry for a PT claim
The timed codes with their minutes and the units the 8-minute rule produces from the total, which the free billing units worksheet on this site works; the untimed codes as one unit each; the modifiers the payer requires on therapy codes; the referring provider and the plan of care dates; the place of service; and the claim as an 837 through a clearinghouse. Medicare's claims processing manual sets the unit rule and its benefit policy manual sets the plan of care and documentation the claim rests on; the software has to hold both.
Where PT claims fail: the unit count and the plan of care
Units billed per code instead of on the total, or an untimed code's minutes added to the timed total, come back as denials or, worse, are paid and recovered in an audit. A plan of care not certified for the date of service, or a recertification missed, comes back as a denial for the whole episode. Software that counts units from the minutes and flags the plan-of-care dates prevents both; software that takes the units as typed prevents neither.
What to ask a vendor to show on your own claims
Take last month's claims and denials. Ask the vendor to enter three visits' minutes and show the units. Ask it to show the plan-of-care dates and what happens when a visit falls outside them. Ask it to show the denial queue with last month's reason codes on it, and the posting of one EOB line by line, which the EOB reconciliation worksheet here works so you know what the right answer looks like. A vendor that can do those on your claims is selling PT billing software; one that cannot is selling a claim form.
What the register keeps beside the software
The claims register: every visit's claim with its units and minutes, the plan of care it fell under, the posted EOB per line, the denial and the corrected claim, and the patient's balance. Eobify Pro keeps that register in a form the clinic owns and can export when the software contract ends; the billing software carries the claim to the payer. The 42 CFR conditions for outpatient physical therapy are what the plan-of-care fields on both are there to satisfy.
The threshold, the KX modifier and the targeted review
Medicare sets an annual threshold for a beneficiary's combined physical therapy and speech-language pathology spend, and a separate one for occupational therapy, above which each claim line must carry the KX modifier attesting that the services remain medically necessary and are documented. Above a higher amount, claims may be selected for targeted medical review. Software that tracks each patient's spend against the year's threshold and prompts the modifier before the claim goes prevents the denial; software that does not leaves the biller to keep the running total on paper. The register keeps the spend to date against the patient with the dates, which is what the prompt and the review both rest on.
Questions people ask about physical therapy billing software
What is the most important feature of physical therapy billing software?
Unit counting from the minutes under the 8-minute rule, on the total across timed codes. Everything else is shared with other specialties; the unit count is the PT clinic's own.
Does PT billing software need to track the plan of care?
Yes. The certification and recertification dates decide whether a visit's claim stands, and software that flags a visit outside them prevents an episode-wide denial.
How is physical therapy billing software different from a PT EMR?
The EMR holds the notes and the plan of care; the billing software builds the claim, sends it and posts the remittance. Many products do both; the billing questions to ask are the same either way.
Where are the PT billing rules published?
The unit rule in the Medicare Claims Processing Manual, chapter 5; the plan of care and documentation in the Benefit Policy Manual, chapter 15; the coverage conditions in 42 CFR 410.60.
What does a PT clinic need for the progress report?
The note has to show a progress report at least once every ten treatment days under Medicare's benefit policy manual, written by the therapist, with the objective measures against the plan's goals. The billing software does not write it, but it should show the treatment-day count so the report is due before the eleventh visit rather than discovered at the audit.
Can the same software bill occupational therapy and speech?
It should, with the GO and GN modifiers per discipline, separate plans of care per discipline for the same patient, and the timed-unit count applied to the OT codes and not to the mostly untimed speech codes. Ask the vendor to show a patient with two disciplines and two plans.
