Salpingo-oophoritis in pregnancy, first trimester

This code signifies an inflammation of the fallopian tubes (salpingitis) and ovaries (oophoritis) occurring during the first trimester of a pregnancy. This condition is typically caused by an infection and can present with pelvic pain, fever, and vaginal discharge.

Apply this code when documentation clearly indicates a diagnosis of salpingo-oophoritis in a pregnant patient who is specifically in her first trimester (up to the end of the 13th week of gestation). Supporting documentation should include physician's notes detailing the diagnosis, the patient's gestational age, and clinical findings consistent with the infection.

• Ensure the documentation explicitly states "first trimester" for accurate trimester assignment.
• Do not confuse this with other pelvic inflammatory conditions not involving both the fallopian tubes and ovaries, or those occurring in different trimesters.
• Code any associated infectious organism (e.g., N74.3 for gonococcal salpingitis) as an additional diagnosis.
