About coding epididymis cyst
The ICD-10-CM code for epididymis cyst is N50.3 (Cyst of epididymis).
Within N50 (other and unspecified disorders of male genital organs), N50.3 is specifically for cyst of epididymis. Related codes cover atrophy of testis (N50.0), vascular disorders of male genital organs (N50.1), other specified disorders of male genital organs (N50.8) and disorder of male genital organs, unspecified (N50.9).
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.
