About coding Rete cell adenoma
The ICD-10-CM code for Rete cell adenoma is D29.20 (Benign neoplasm of unspecified testis).
Within D29.2, choose D29.20 (unspecified testis) only when documentation doesn't support a more specific option: right testis (D29.21) and left testis (D29.22).
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.
