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
