ICD-10 code for corpus cavernosum disease

The ICD-10-CM code for corpus cavernosum disease is N48.9 (Disorder of penis, 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 N48.9.

Within N48, choose N48.9 (Disorder of penis, unspecified) only when documentation doesn't support a more specific option: leukoplakia of penis (N48.0), balanitis (N48.1), other inflammatory disorders of penis (N48.2), priapism (N48.3), ulcer of penis (N48.5), Induration penis plastica (N48.6) and other specified disorders of penis (N48.8).

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 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.
