A51.42
BillableSecondary syphilitic female pelvic disease
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This is a sexually transmitted infection (syphilis) that has progressed to the secondary stage and is affecting the female reproductive organs and pelvis. It occurs when untreated early syphilis spreads throughout the body and causes inflammation in the pelvic region.
Coding Tips
- •Verify that the documentation specifically indicates secondary syphilis with pelvic involvement in females; do not use this code for male patients or other stages of syphilis
- •Ensure the medical record documents the pelvic manifestation (such as salpingitis, oophoritis, or endometritis) and confirm this is secondary syphilis rather than latent or tertiary stages
