About coding testicular endocrine dysfunction
The ICD-10-CM code for testicular endocrine dysfunction is E29.9 (Testicular dysfunction, 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 E29.9.
Within E29, choose E29.9 (unspecified) only when documentation doesn't support a more specific option: testicular hyperfunction (E29.0), testicular hypofunction (E29.1) and other testicular dysfunction (E29.8).
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.
