About coding prostate infarct
The ICD-10-CM code for prostate infarct is N42.89 (Other specified disorders of prostate).
Within N42.8, choose N42.89 (Other specified disorders of prostate) only when documentation doesn't support a more specific option: Prostatodynia syndrome (N42.81), Prostatosis syndrome (N42.82) and cyst of prostate (N42.83).
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.
