ICD-10 code for testis ectopic

The ICD-10-CM code for testis ectopic is Q53.00 (Ectopic testis, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q53.00.

Within Q53.0, choose Q53.00 (unspecified) only when documentation doesn't support a more specific option: unilateral (Q53.01) and testes, bilateral (Q53.02).

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), DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597) and DRG 795 (Normal Newborn, relative weight 0.2022), in MDC 12 (Diseases and Disorders of the Male Reproductive System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
