A physical therapist assistant (PTA) or occupational therapy assistant (OTA) cannot sign a Medicare progress note in a skilled nursing facility (SNF). Under Medicare Part A, only the treating physical therapist (PT), occupational therapist (OT), or speech-language pathologist (SLP) can complete and sign that note.
The assistant can document what happened in a session. Only the therapist can judge what it means.
Most guidance on this question comes from outpatient Part B billing rules built around specific reimbursement codes. A covered SNF Part A stay runs on a different rail entirely.
Therapy sits inside the facility’s per diem payment, not a separately billed service. That one difference decides who can sign a note, when a reevaluation is actually required, and what makes a therapy goal defensible in a review.
Quick Summary
Only the treating PT, OT, or SLP can sign a Medicare SNF progress note. Assistants can contribute documentation but not clinical judgment. Reevaluation in a SNF is a documentation question, not a separate billable event the way it is in outpatient therapy. Goals must be individualized to the resident and updated when the condition changes. Missing any of these three things does not make the paperwork incomplete. It makes it indefensible.

Why Most Therapy Documentation Guides Get the SNF Signing Rules Wrong
Search for SNF therapy documentation rules and most results describe outpatient Part B billing: CPT (Current Procedural Terminology) code 97164 for a physical therapy re-evaluation, a GP modifier, an eight-minute rule. None of it applies inside a covered Part A stay.
According to the Centres for Medicare & Medicaid Services (CMS) SNF Billing Reference, Medicare pays SNFs a per diem rate under a prospective payment system (PPS) (Source: CMS.gov, SNF Billing Reference MLN006846). The facility’s per diem payment bundles therapy in. It is not billed as a standalone service the way outpatient re-evaluation codes are.
An outpatient clinic bills each visit and each re-evaluation as its own claim line. A SNF bills one per diem rate for the whole day of care, therapy included, the same bundling logic behind the five-day therapy threshold for Part A coverage.
A reviewer auditing a SNF stay checks whether the record supports that entire day of skilled care. They are not verifying a CPT line item for a re-evaluation that was never submitted.
This is the detail most PT-clinic-focused guides miss. Outpatient re-evaluation rules exist because a re-eval is a separately payable event that has to be justified to a payer. Inside a Part A stay, there is no separate payment decision to justify. The only question a reviewer asks is whether the resident still needs skilled care, which means the signing, re-evaluation, and goal rules built for outpatient billing do not transfer cleanly to a SNF chart.
Who Can Sign a SNF Therapy Progress Note
What the Treating Therapist Signs
Medicare requires the treating PT, OT, or SLP to complete and sign the progress note at least once every ten treatment days. The ten-day timing requirement and the day-one evaluation standard are covered in everything else Medicare checks in your therapy chart; this post focuses on who is allowed to sign, not when.
What a Therapy Assistant Can Document
A PTA or OTA can record what happened in a treatment session: techniques used, resident response, and progress toward established goals. An assistant cannot make the clinical judgment about whether that progress justifies continuing, modifying, or ending skilled care. That judgment belongs to the therapist alone.
A PTA might record that a resident completed ten minutes of gait training with a rolling walker and tolerated it well. Only the PT decides whether that tolerance means the resident is ready for a cane, should stay at the current device, or needs a different approach.
General Supervision in the SNF Setting
Assistants in a SNF work under general supervision, not direct supervision. That standard requires initial direction and periodic inspection of the activity (Source: CMS, Medicare Benefit Policy Manual, Chapter 8, Section 30.3).
The supervising therapist does not need to be physically present for every treatment session.
One narrower point is worth separating out. A CMS transmittal corrected Chapter 8 Section 30.4.1.1 after it wrongly stated that a maintenance therapy program in a SNF must be performed by a therapist, not an assistant. CMS clarified that federal regulation 42 CFR 409.32 does not draw that distinction for the SNF setting, unlike the home health and outpatient rules (Source: CMS.gov, Transmittal 179, Pub. 100-02, Chapter 8).
That correction covers who can perform a maintenance program. It does not change who signs the progress note. That responsibility still sits with the therapist alone.
What Actually Triggers a SNF Re-evaluation
Outpatient therapy bills a re-evaluation using CPT 97164 or 97168 when a resident shows a significant, unanticipated improvement or decline. Continuous assessment of ordinary progress does not qualify. CMS guidance treats that as routine progress tracking, not a billable re-evaluation.
A covered Part A stay has no such billing trigger. The re-evaluation question in a SNF is not “can I bill for this.” It is “does my documentation show I noticed the change and responded to it.”
Consider a resident recovering from a hip fracture who progressed steadily for three weeks, then plateaus for five straight sessions. That plateau calls for a documented reassessment, not a note that keeps repeating the same plan without acknowledging why progress stopped.
A therapist who keeps treating a plateaued resident without documenting a reassessment is not protected by the absence of a billing code. The lack of a billing trigger does not remove the documentation expectation. It just moves where that expectation shows up. Instead of a coded claim line, it lives in the ongoing progress note itself.
What Makes a Therapy Goal Defensible in a Medicare Review
Medicare requires an individualized assessment showing that a resident’s condition demands the specialized judgment, knowledge, and skill of a qualified therapist (Source: CMS, Medicare Benefit Policy Manual, Chapter 8, Section 30.4). A goal that could describe any resident with a similar diagnosis does not meet that standard.
A goal copied forward from the prior week’s note is not a goal. It is a placeholder that tells a reviewer the therapist stopped individualizing care days ago.
A goal that reads “resident will improve mobility” fits any resident on any unit. A goal that reads “resident will ambulate 50 feet with a front-wheeled walker and contact guard assist, reduced from moderate assist, within two weeks” is individualized, measurable, and gives a reviewer something specific to verify against the chart.
Therapists must routinely assess and document beneficiary goals, and the record must avoid vague or subjective descriptions of care (Source: FCSO Medicare, Inpatient SNF Services Common Denials and How to Avoid Them). A goal set once at admission and never revisited fails that standard by week two.
Boilerplate goals do not usually fail because the therapist lacks clinical judgment. They fail because the documentation habit was built for speed, not defense, and nobody revisits a goal after it is typed the first time.
Why Complete Notes Still Get Denied
A chart can have every required note present and still fail review. Presence is not the same as defensibility.
A signed note from the wrong person, a reevaluation that never shows what changed, or a goal that reads the same in week one and week six are not missing documentation. They are documentation that actively works against the facility.
The fix is not more paperwork. It means confirming the person signing has the authority to sign, the re-evaluation actually names what changed, and the goal reads like it belongs to this resident and no one else. These three checks are part of how documentation ties together across your SNF’s compliance program.
Frequently Asked Questions
No. Medicare requires the treating PT, OT, or SLP to sign the progress note. A PTA or OTA can document session details, but the clinical judgment and signature belong to the therapist.
No. Therapy inside a covered Part A stay is paid through the facility's per diem rate, not billed by CPT re-evaluation code. The re-evaluation still needs to be documented; it is not a separate billing event.
At least once every ten treatment days, by the treating therapist, not the assistant.
A significant, unanticipated improvement or decline in a resident's functional status, or a failure to respond to the current treatment plan. The re-evaluation should document what changed and how the plan responded.
Because a complete chart is not automatically a defensible one. A note signed by the wrong person, a re-evaluation that never names what changed, or a goal that never varies over several weeks can still trigger a denial.
A goal that is individualized to the resident, measurable, and updated when the resident's condition changes. Generic or copied-forward goals do not meet Medicare's individualized-assessment standard.
