About coding masochism
The ICD-10-CM code for masochism is F65.51 (Sexual masochism).
Within F65.5 (Sadomasochism), F65.51 is specifically for sexual masochism. Related codes cover unspecified (F65.50) and sexual sadism (F65.52).
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 887 (Other Mental Disorder Diagnoses, relative weight 1.1139), 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.
