About N47.4

N47.4 is the ICD-10-CM diagnosis code for benign cyst of prepuce. It belongs to category N47 (disorders of prepuce), block N40-N53 (diseases of male genital organs) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N47 (disorders of prepuce), N47.4 is specifically for benign cyst of prepuce. Related codes cover adherent prepuce, newborn (N47.0), phimosis (N47.1), Paraphimosis (N47.2), Deficient foreskin (N47.3), adhesions of prepuce and glans penis (N47.5), Balanoposthitis (N47.6), other inflammatory diseases of prepuce (N47.7) and other disorders of prepuce (N47.8).

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 727 (Inflammation of the Male Reproductive System with MCC, relative weight 1.37), DRG 728 (Inflammation of the Male Reproductive System without MCC, relative weight 0.8224) and DRG 795 (Normal Newborn, relative weight 0.2022), in MDC 12 (Diseases and Disorders of the Male Reproductive System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 605 (redundant prepuce and phimosis).
