ICD-10 code for Anhedonia

The ICD-10-CM code for Anhedonia is R45.84 (Anhedonia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R45.84.

Within R45.8 (other symptoms and signs involving emotional state), R45.84 is specifically for Anhedonia. Related codes cover low self-esteem (R45.81), Worries (R45.82), excessive crying of child, adolescent or adult (R45.83), Homicidal and suicidal ideations (R45.85), emotional lability (R45.86), Impulsiveness (R45.87), nonsuicidal self-harm (R45.88) and other symptoms and signs involving emotional state (R45.89).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
