Infection oth prt genitl trct in pregnancy, third trimester

This code signifies an infection affecting any part of the female genital tract, excluding the uterus, cervix, or vagina, occurring during the third trimester of pregnancy. Examples include infections of the vulva, perineum, or Bartholin's gland. The infection is considered a complication of the pregnancy.

Apply this code when documentation specifies a genital tract infection, such as vulvitis, perineal cellulitis, or Bartholin's abscess, in a pregnant patient who is in her third trimester. The physician's notes should clearly link the infection to the pregnancy.

• Always sequence this code as a primary diagnosis when the infection is the reason for the encounter.
• Do not use this code for infections of the uterus (O23.0-), cervix (O23.1-), or vagina (O23.3-); specific codes exist for those sites.
• Ensure the documentation explicitly states "third trimester" or provides gestational age indicating the third trimester (e.g., 28 weeks 0 days to 40 weeks 6 days).
