ICD-10 code for testis and scrotum malformation

The ICD-10-CM code for testis and scrotum malformation is Q55.20 (Unspecified congenital malformations of testis and scrotum). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q55.20.

Within Q55.2, choose Q55.20 (Unspecified congenital malformations of testis and scrotum) only when documentation doesn't support a more specific option: Polyorchism (Q55.21), Retractile testis (Q55.22), scrotal transposition (Q55.23) and other congenital malformations of testis and scrotum (Q55.29).

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.
