About coding priapism
The ICD-10-CM code for priapism is N48.30 (Priapism, 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 N48.30.
Within N48.3, choose N48.30 (unspecified) only when documentation doesn't support a more specific option: due to trauma (N48.31), due to disease classified elsewhere (N48.32), drug-induced (N48.33) and other priapism (N48.39).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
