Why was my physical therapy denied?
Short answer: therapy is usually approved to start — the denials come later, around continued visits. Plans cap the number of visits, then require proof that you're still making functional progress. If the notes read like you're "maintaining" rather than improving, or there's no current plan of care, additional visits get denied — even when you clearly still benefit. The same pattern applies to occupational and speech therapy.
If your PT, OT, or speech therapy was cut off, it's rarely because the insurer decided you never needed it. It's almost always one of a few documentation-and-timing reasons — and most are fixable.
The most common reasons therapy gets denied
- You hit the visit cap. Most plans cover a set number of therapy visits per year (commonly 20–60). Past that, every additional visit needs prior authorization — and without it, claims are denied automatically.
- The notes don't show functional progress. This is the big one. Insurers cover skilled therapy aimed at measurable improvement — strength, range of motion, walking distance, independence in daily tasks, speech clarity. If progress notes are vague or flat, the insurer concludes therapy is no longer "medically necessary."
- It looks like "maintenance." Therapy whose goal is simply holding steady is generally treated as non-covered maintenance. The exception: when a skilled therapist is needed to prevent decline (under Medicare, this is the Jimmo standard) — but that has to be documented explicitly.
- No current plan of care. Coverage requires an active plan of care with measurable goals, reviewed (and often signed) by your provider. A lapsed or missing plan is an easy denial.
- Prior authorization wasn't obtained. When the plan requires authorization for therapy (or for visits beyond the initial set), skipping it is one of the most common denial reasons of all.
What keeps therapy covered
- A current plan of care with specific, measurable functional goals.
- Objective progress documented at each re-evaluation — numbers, not just "tolerating well."
- A clear reason skilled therapy is still needed — why a licensed therapist, not an independent home program, is required to reach the goals.
- Authorization once you near the cap, submitted with that documentation rather than after a denial.
- If you're mainly maintaining, an explicit note on what would decline without skilled therapy — that's what can keep maintenance-phase care covered or win it on appeal.

Frequently asked questions
Can I get more physical therapy visits after I hit the limit?
Often yes. Visits beyond the cap require prior authorization supported by documentation — a current plan of care, objective progress, and why skilled therapy is still needed. When that's submitted up front, additional visits are frequently approved; when it's missing, they're denied.
Why does my insurer say my therapy is "maintenance"?
Insurers cover skilled therapy aimed at improvement. If the documented goal is sustaining current function rather than improving it, they classify it as maintenance, which is generally not covered — unless a skilled therapist is needed to prevent decline, which must be documented.
Does Medicare cover physical therapy long-term?
Medicare covers medically necessary outpatient therapy with no hard dollar cap, but above the 2026 KX-modifier threshold of $2,480 (PT and speech combined; a separate $2,480 for OT) your therapist must attest and document that continued skilled therapy is necessary. Medicare also covers skilled maintenance therapy under the Jimmo standard when needed to prevent decline.
Can I appeal a therapy denial?
Yes, and therapy denials are commonly overturned — especially when the original notes didn't clearly document functional progress or skilled need that actually existed. Adding that documentation, or appealing with it, often reverses the denial.
Does this apply to occupational and speech therapy too?
Yes. OT and speech-language therapy follow the same structure — visit limits, a plan of care, and documented functional progress (in daily-living tasks for OT; in communication or swallowing for speech). Some plans also exclude purely developmental speech delay.
