About coding Virilism
The ICD-10-CM code for Virilism is E25.9 (Adrenogenital disorder, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on E25.9.
Within E25, choose E25.9 (Adrenogenital disorder, unspecified) only when documentation doesn't support a more specific option: congenital adrenogenital disorders associated with enzyme deficiency (E25.0) and other adrenogenital disorders (E25.8).
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 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044) and DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), in MDC 10 (Endocrine, Nutritional and Metabolic 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.
