RxHCCHCC 133 — Personality Disorders, Anxiety, and Other Specified Mental Disorders
0.000What This Code Means
An eating disorder that is present but cannot be classified into a specific type, often used when insufficient information is available to determine the exact diagnosis.
Coding Tips
- •This is a default code; attempt to obtain more specific diagnostic information from the provider before assigning this code
- •Query the clinician if any eating disorder symptoms are documented but not formally diagnosed to allow for more specific coding
Clinical Significance
This unspecified code indicates the presence of an eating disorder without sufficient documentation to classify the specific type. It represents a significant missed opportunity for clinical accuracy and potentially for risk adjustment. Coders should query providers to determine the specific eating disorder type, as some types (anorexia nervosa, bulimia nervosa) carry substantially higher HCC values.
Documentation Requirements
- ✓Documentation of disordered eating behavior causing clinical concern
- ✓Evidence that symptoms represent a psychiatric eating disorder, not a medical appetite condition
- ✓Provider acknowledgment of an eating disorder diagnosis
- ✓Any available detail on the type of disordered eating to enable specificity
- ✓Recommendation for psychiatric or eating disorder specialist evaluation if type is undetermined
