Physical Therapy Credentialing and Payer Enrollment

Physical therapy credentialing is the process of enrolling a physical therapist, and the practice they bill under, with each insurer that pays for their visits: Medicare as a physical therapist in private practice (PTPP) through PECOS or the CMS-855I, commercial plans through their own network application or the therapy network they delegate to, such as Optum Physical Health or American Specialty Health, and Florida Medicaid through AHCA. Each payer verifies the therapist, contracts with the practice and sets its own effective date. Until then, visits are out of network.

PT enrollment has rules other specialties do not: Medicare inspects the office before it grants billing privileges, physical therapist assistants cannot enroll at all, physical therapists cannot opt out, and several large plans hand therapy to a separate network. This page covers those. If you need the general sequence first, start with what provider credentialing is.

A physical therapist who treats Medicare patients outside a hospital or facility enrolls as a physical therapist in private practice, on PECOS or the paper CMS-855I. Under 42 CFR 410.60(c), as CMS restates it in section 10.2.3.10 of its enrollment manual, the therapist must:

1. Hold a state license and practice only within its scope.
2. Practice regularly in a solo practice, partnership or group practice, or as an employee of one.
3. Bill Medicare only for services in the practice's own office space or the patient's home. The office space must be owned, leased or rented by the practice and used only for the practice; a hospital, critical access hospital or skilled nursing facility is not a patient's home.
4. Treat the practice's own patients, for whom the practice collects the fees.

Every PTPP answers Section 2J of the 855I, unless the therapist is joining an established PT group, a physician-directed group or a non-professional corporation and reassigning benefits to it. First Coast, the Florida Medicare contractor, also asks for a signed certification statement (no stamped signatures) and the CMS-588 for electronic payment (First Coast PTPP enrollment).

The site visit. For a PT or PT group in private practice, the contractor orders a site visit on the initial application, again on revalidation, and again when a location is added or moved. CMS tells contractors not to grant billing privileges until the visit is done and reviewed. Revalidation comes every five years. The full PECOS walkthrough is on Medicare provider enrollment and what PECOS is.

Qualified therapist. Medicare's definition requires graduation from an accredited program (CAPTE) and a state-approved exam. Internationally educated therapists qualify through a credentials evaluation such as FSBPT's or the Foreign Credentialing Commission on Physical Therapy's (FCCPT), which CMS names in the same section.

A PT group in private practice enrolls on the CMS-855B, and each therapist who bills through it enrolls individually and reassigns benefits to the group on the 855I. The separate CMS-855R reassignment form was retired into the 855I. CMS draws a line between that and outpatient physical therapy providers that enroll on the CMS-855A: those are facility-type providers on a different track, not PT groups. Knowing which you are decides the form, the survey and the timeline.

The group and the individual need different numbers in different boxes: the group's Type 2 NPI and tax ID, the therapist's Type 1 NPI. Our page on NPI Type 1 vs Type 2 shows which goes where.

Florida Medicaid pays for physical therapy “provided by licensed, Medicaid-participating physical therapists” and by supervised physical therapy assistants, according to AHCA's therapy services page. Coverage is narrow for adults: AHCA's physical therapy coverage page covers recipients 20 and younger under the coverage policy, recipients 18 and older in a Long-Term Care plan, and only limited wheelchair evaluation and fitting for recipients 21 and older otherwise.

Physical therapy is a minimum covered service for every Managed Medical Assistance and Long-Term Care plan, so a pediatric or long-term-care practice enrolls with AHCA and then with the plans its patients carry. Fee-for-service therapy authorizations go through AHCA's utilization management contractor, eQHealth Solutions; managed care patients get authorization through their plan. The Medicaid enrollment sequence itself is on Medicaid provider enrollment.

1. Settle the entity. Solo PTPP, PT group, or facility on the 855A. That choice sets every form after it.
2. NPIs and tax ID. A Type 1 NPI for each therapist, a Type 2 for the group, with the legal name and address written identically everywhere.
3. Lease and space. Have the lease (or deed) for space used only by the practice ready before the Medicare site visit.
4. CAQH. Build, upload, authorize and attest each therapist's profile.
5. Medicare. Group on the 855B, therapists on the 855I with reassignment, CMS-588, CMS-460 if participating. Expect the site visit.
6. Commercial plans. Apply through the door each plan uses for therapy, not the generic route.
7. Medicaid, if the patient mix justifies it.
8. Follow up weekly until each contract and effective date is in writing, then load them before billing.

Everything those steps ask for is on one list: what we need to start credentialing. The longer walk-through for any specialty is how to get in network with insurance companies.
