What This Code Means
R46.81 is the ICD-10-CM diagnosis code for obsessive-compulsive behavior. Repetitive behaviors or thought patterns that the person feels compelled to perform, such as excessive checking, arranging, or cleaning. R46.81 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering symptoms and signs involving cognition, perception, emotional state and behavior (r40-r46).
R46.81 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code when OCD behaviors are observed but a formal OCD diagnosis hasn't been established.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R46.81 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code when OCD behaviors are observed but a formal OCD diagnosis hasn't been established
