Chlamydial vulvovaginitis

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A sexually transmitted infection caused by chlamydia bacteria that causes inflammation and irritation of the vulva and vagina in women. Symptoms typically include abnormal vaginal discharge, pain during urination, and vaginal discomfort.

Coding Tips

  • •Verify documentation specifies chlamydial infection of the vulvovaginitis (not other sites like cervix or urethra) to ensure correct code selection within the A56 category
  • •Confirm whether this is an initial diagnosis or follow-up visit, as this may affect documentation requirements and whether additional codes for sexual partner notification or treatment compliance are needed
