F15.99

HCC Category Mapping

What This Code Means

A condition where stimulant drug use causes an unspecified mental or physical health problem in someone with unspecified use pattern.

Coding Tips

• •This is the least specific code; use only when the exact stimulant-induced disorder cannot be determined
• •Attempt to identify the specific disorder for more accurate coding when possible

Clinical Significance

Stimulant use, unspecified with unspecified stimulant-induced disorder is the most nonspecific code in the stimulant use category, with both the use pattern and the induced disorder left uncharacterized. This code should only be used when documentation is truly minimal and represents the greatest opportunity for improvement through provider queries. It still captures HCC value but is the most vulnerable to audit challenge.

Documentation Requirements

• ✓Documentation of stimulant use with some evidence of an induced disorder
• ✓Query to provider to specify both the use pattern (abuse vs. dependence) and the induced disorder
• ✓Any clinical evidence supporting the presence of a substance-related complication
• ✓Documentation of attempts to obtain more specific information
• ✓Follow-up plan to clarify the clinical picture
