What N465 means

Physical therapy claims often come under review because they involve repeated visits and time-based units. When a payer wants to check what happened in those visits, it asks for the therapy documentation. N465 says that documentation, the notes or report, was not received.

The remark usually shows up with CARC 252 or CARC 226 on the therapy lines.

What a therapy records packet typically contains

  • Initial evaluation: findings, functional limitations, and goals.
  • Plan of care: treatment types, frequency, and duration.
  • Daily treatment notes: interventions performed on each billed date, with minutes for timed services.
  • Progress reports: measurable progress toward goals at intervals.
  • Discharge summary if therapy has ended.

A payer may ask for all of these or only some. The request letter usually says which.

Steps to take

  1. Find the payer’s request and note the dates of service in question.
  2. Pull the notes for those dates, plus the evaluation and plan of care they depend on.
  3. Check that each note is signed by the treating therapist and dated.
  4. Organize the packet by date with a cover sheet listing the claim number and dates included.
  5. Submit and track receipt, then request reprocessing.

How to prevent it

Therapy practices benefit from a standing “records-ready” process: notes finalized within a short window after each visit, and a template packet that can be exported quickly. Late or unsigned notes are the main reason practices miss documentation deadlines.

Codes that may appear with N465

  • CO-252 (An attachment/other documentation is required to adjudicate this claim/service.): Documentation is required; N465 specifies physical therapy notes or a report.
  • CO-226 (Information requested from the Billing/Rendering Provider was not provided or not provided timely or was insufficient/incomplete.): Information requested from the provider was not provided.
  • CO-B12 (Services not documented in patient's medical records.): Services not documented in the patient's medical records.
  • N466 (Incomplete/invalid Physical Therapy Notes/Report.): Physical therapy notes or report were received but were incomplete or invalid.
  • N485 (Missing Physical Therapy Certification.): The physical therapy certification, the signed plan of care, is missing.
  • N393 (Missing progress notes/report.): Progress notes or report are missing.

N465 FAQ

Which therapy documents should I send?

Send what the payer requests. Commonly that includes the initial evaluation, the plan of care, daily treatment notes for the billed dates, and any progress reports.

Is N465 the same as a missing plan of care certification?

No. A missing certification is usually flagged with N485. N465 is about the therapy notes or report that show what was done.

Do daily notes need treatment minutes?

For timed services, yes. Minutes support the units billed, and payers look for them.
