ICD-10-CM N48.32
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

N48.32 is a billable ICD-10-CM diagnosis code for priapism due to disease classified elsewhere. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 729 through 730. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 31 closely related codes. The code is a manifestation code that cannot be reported as the principal diagnosis. Coders also document this condition as priapism. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified male genital disorders.

The ICD-10-CM code for priapism due to disease classified elsewhere is N48.32 (sometimes written as N4832). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is N48.32 (Priapism) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report priapism due to disease classified elsewhere on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does N48.32 group to?

On inpatient claims, priapism due to disease classified elsewhere maps to MS-DRG 729, 730, with relative weights from 0.6595 to 1.0553 depending on complications. Higher weights mean higher Medicare reimbursement.

CMS lists N48.32 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 31 closely related codes in its exclusion list.

Can N48.32 be a principal diagnosis?

No. This is a manifestation code: priapism due to disease classified elsewhere describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
