What to document for medical necessity

Payers look for a record that supports the diagnosis and the level of care. For adjustment disorders that usually means:

  • The identifiable stressor and when it started
  • The predominant symptoms, which decide the sixth character
  • Why the reaction is out of proportion to the stressor or impairs functioning
  • A review date - adjustment disorders are expected to be time-limited, so revisit the code if symptoms persist
  • Treatment plan goals tied to the stressor and the symptoms
