ICD-10 code for testis hypertrophy

The ICD-10-CM code for testis hypertrophy is N44.8 (Other noninflammatory disorders of the testis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N44.8.

Within N44, choose N44.8 (Other noninflammatory disorders of the testis) only when documentation doesn't support a more specific option: torsion of testis (N44.0), cyst of tunica albuginea testis (N44.1) and benign cyst of testis (N44.2).

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 729 (Other Male Reproductive System Diagnoses with CC/MCC, relative weight 1.0544) and DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), in MDC 12 (Diseases and Disorders of the Male Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
