About coding male infertility
The ICD-10-CM code for male infertility is N46.9 (Male infertility, unspecified). The official index lists 17 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N46.9.
Within N46, choose N46.9 (unspecified) only when documentation doesn't support a more specific option: azoospermia (N46.0), oligospermia (N46.1) and other male infertility (N46.8).
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.
