What This Code Means
A54.02 is the ICD-10-CM diagnosis code for gonococcal vulvovaginitis, unspecified. This code describes a sexually transmitted infection caused by gonorrhea bacteria affecting the vulva and vagina in females, without specification of which structures are primarily involved. It represents inflammation and infection of the female external and internal genital tissues due to gonococcal infection. A54.02 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering infections with a predominantly sexual mode of transmission (a50-a64).
A54.02 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Verify documentation specifies gonococcal infection of the vulva and/or vagina; if other sites are involved (cervix, urethra, bartholin glands), use more specific codes from the A54.0x series.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A54.02 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies gonococcal infection of the vulva and/or vagina; if other sites are involved (cervix, urethra, bartholin glands), use more specific codes from the A54.0x series
- •This code is unspecified, so if the medical record provides more detail about which anatomical structures are affected, consider using a more specific code (A54.01 for cervicitis, A54.03 for bartholin gland abscess, etc.)
