What is the Activity Prescription Form (APF)?

Providers complete APFs to communicate the worker’s:

  • Ability to work
  • Functional capacities
  • Physical restrictions
  • Treatment plan

APFs are also used to help:

  • Employers develop modified work plans while their worker is recovering.
  • L&I claim managers understand the worker’s ongoing treatment and medical progress, and to authorize time-loss benefits.
  • Health Services Coordinators (HSCs) collaborate with attending providers, employers, and workers to coordinate treatment and return to work.
  • Vocational rehabilitation counselors (VRCs) build appropriate return to work plans.
  • Workers understand what they can do. It can be used as a motivator in their healing process.

Who may ask the provider to complete an APF?

  • The Claim Manager
  • The worker’s Vocational Rehabilitation Counselor (VRC)
    • A VRC may request an APF to clarify or update information about the worker’s physical capacity or condition.
  • Self-Insured Employers (SIEs) or their 3rd party administrators
    • May request, but the APF is paid for by the employer

NOTE: L&I does not pay for APFs completed at the request of:

  • Attorneys, or
  • Employers covered by L&I

  • APFs
