A54.1 is a billable ICD-10-CM diagnosis code for gonococcal infection of lower genitourinary tract with periurethral and accessory gland abscess. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 727 through 728, 742 through 743, 757 through 759. 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 32 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Sexually transmitted infections (excluding HIV and hepatitis).

Questions About A54.1Overview

Is A54.1 (Gonococcal infection) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report gonococcal infection of lower genitourinary tract with periurethral and accessory gland abscess on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does A54.1 group to?

When gonococcal infection of lower genitourinary tract with periurethral and accessory gland abscess is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 759, 727, 743, 728, 758, 757, with relative weights from 0.7687 to 1.8448 depending on complications. Higher weights mean higher Medicare reimbursement.

Is A54.1 a CC or MCC?

CMS lists A54.1 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 32 closely related codes in its exclusion list.

Can A54.1 be reported with N34.1?

Not as a rule. The Excludes1 note at block A50-A64, which applies to A54.1, lists "nonspecific and nongonococcal urethritis (N34.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of A54.1?

Under the General Equivalence Mappings, gonococcal infection of lower genitourinary tract with periurethral and accessory gland abscess converts to ICD-9-CM 098.0 (acute gc infect lower gu). The mapping is approximate, so confirm the match fits the documentation.
