About coding gender dysphoria
The ICD-10-CM code for gender dysphoria is F64.9 (Gender identity disorder, unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F64.9.
Within F64, choose F64.9 (Gender identity disorder, unspecified) only when documentation doesn't support a more specific option: Transsexualism (F64.0), dual role transvestism (F64.1), gender identity disorder of childhood (F64.2), other gender identity disorders (F64.8) and gender identity disorder, in remission (F64.A).
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.
