Specialties

Billing rules change with the specialty

For each specialty, we write down its billing rules, turn them into checks and test them before it goes live. Physical therapy is live. Tell us your specialty if you bill something else.

By requestTell us your specialty, and your billing plan sets out how we will bill it.

How we add a specialty

A physical therapy claim depends on minutes, units and a signed plan of care. A psychotherapy claim depends on session length. A dermatology claim depends on the procedure. A biller who knows physical therapy well can still get dermatology wrong. So every specialty goes through the same steps before it goes live.

  1. We write down the rules

    We collect the specialty's billing rules from public sources: Medicare's manuals and code edits, the CPT code descriptions, and the written policies of the insurance companies your practice bills. Each rule gets a plain description, its source and the date we checked it.

  2. We turn each rule into a check

    Every claim has to pass every check before it goes out. A failed check stops the claim and sends it to one of our billing specialists, not to the insurance company.

  3. We test the checks

    We build test claims that should pass and test claims that should fail, and run every check against them. What fails gets fixed and tested again.

We build and test the billing checks for each specialty before we bill it. Physical therapy is live.

The same scope in every specialty

The parts of billing we run, check or track are the same for every practice. What changes by specialty is the rules each claim is checked against.

Questions about specialties

Billing rules differ by specialty, so we build and test the checks for each one before we bill it. Physical therapy is live.

Specialty focus is common: in Tebra's surveys of billing companies, the share highly focused on specific specialties rose from 43% in 2023 to 57% in 2025.16

Both are by request. Tell us about your practice, and your billing plan sets out how we will bill them.
