About coding penis chronic ulcer
The ICD-10-CM code for penis chronic ulcer is N48.5 (Ulcer of penis).
Within N48 (other disorders of penis), N48.5 is specifically for ulcer of penis. Related codes cover leukoplakia of penis (N48.0), balanitis (N48.1), other inflammatory disorders of penis (N48.2), priapism (N48.3), Induration penis plastica (N48.6), other specified disorders of penis (N48.8) and disorder of penis, unspecified (N48.9).
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.
