About A54.02

A54.02 is the ICD-10-CM diagnosis code for gonococcal vulvovaginitis, unspecified. It belongs to category A54 (gonococcal infection), block A50-A64 (infections with a predominantly sexual mode of transmission) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within A54.0, choose A54.02 (Gonococcal vulvovaginitis, unspecified) only when documentation doesn't support a more specific option: gonococcal infection of lower genitourinary tract, unspecified (A54.00), gonococcal cystitis and urethritis, unspecified (A54.01), gonococcal cervicitis, unspecified (A54.03) and other gonococcal infection of lower genitourinary tract (A54.09).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 757 (Infections, Female Reproductive System with MCC, relative weight 1.4649), DRG 758 (Infections, Female Reproductive System with CC, relative weight 0.9908) and DRG 759 (Infections, Female Reproductive System without CC/MCC, relative weight 0.7691), in MDC 13 (Diseases and Disorders of the Female 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.

It is on the CMS list of diagnoses consistent only with female 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 098.0 (gonococcal infection (acute) of lower genitourinary tract).
