About coding penis inflammation
The ICD-10-CM code for penis inflammation is N48.29 (Other inflammatory disorders of penis).
Within N48.2, choose N48.29 (Other inflammatory disorders of penis) only when documentation doesn't support a more specific option: abscess of corpus cavernosum and penis (N48.21) and cellulitis of corpus cavernosum and penis (N48.22).
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 727 (Inflammation of the Male Reproductive System with MCC, relative weight 1.37) and DRG 728 (Inflammation of the Male Reproductive System without MCC, relative weight 0.8224), 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.
