About coding communicating hydrocele
The ICD-10-CM code for communicating hydrocele is N43.2 (Other hydrocele). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N43.2.
Within N43, choose N43.2 (Other hydrocele) only when documentation doesn't support a more specific option: Encysted hydrocele (N43.0), infected hydrocele (N43.1), hydrocele, unspecified (N43.3) and spermatocele of epididymis (N43.4).
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.
