Documenting Functional Impairment

Module 5: Admissions, Eligibility, and Medical Necessity · Lesson 2 of 3

13 min Back to module

Story opener

Thursday, 4:40 p.m. A participant is sitting across from you, your supervisor wants three notes before you leave, and the answer you need is not in any binder on the shelf. This lesson is the part of the job nobody handed you in orientation.

Learning objectives

  • Be able to behavior plus frequency plus consequence equals usable evidence
  • Be able to attribute every impairment statement to a source

Lesson

Impairment must be described in behavior and frequency, not adjectives.

Replace 'poor hygiene' with 'showers once every 10-14 days; reports being asked to leave a job interview due to appearance.' Replace 'isolative' with 'leaves apartment once weekly for groceries; no contact with peers in six months.'

Gather evidence from multiple sources: participant self-report, observation, collateral, and prior records. Note the source for each statement.

Maryland guidance & authority labels

Every statement below is labeled so you know what is binding regulation, what is only proposed, what is professional guidance, and what is our house standard.

  • COMAR — current

    Admission requires a qualifying diagnosis, documented functional impairment, and a statement of why the service is medically necessary and what the risk is without it.

  • Internal best practice

    Write medical necessity as four linked sentences: diagnosis, functional impairment, the service, the risk without it.

Common mistakes

  • Describing what you did without describing what the participant did.

    Do this instead — Record the intervention and the participant's observable response to it.

  • Treating regulation as a filing chore separate from practice.

    Do this instead — Let the required elements shape the session itself, so documentation writes itself.

Practical examples

Practical example

Instead of 'met with participant to discuss goals,' write: 'Reviewed the transportation objective; participant identified the #22 route unassisted and named one back-up plan. Verbal prompt needed once. Next session: practice the transfer at Mondawmin.'

Key takeaways

  • Behavior plus frequency plus consequence equals usable evidence
  • Attribute every impairment statement to a source
