About coding nonsuicidal self-mutilation
The ICD-10-CM code for nonsuicidal self-mutilation is R45.88 (Nonsuicidal self-harm).
Within R45.8 (other symptoms and signs involving emotional state), R45.88 is specifically for nonsuicidal self-harm. Related codes cover low self-esteem (R45.81), Worries (R45.82), excessive crying of child, adolescent or adult (R45.83), Anhedonia (R45.84), Homicidal and suicidal ideations (R45.85), emotional lability (R45.86), Impulsiveness (R45.87) 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 883 (Disorders of Personality and Impulse Control, relative weight 1.7697), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
