About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Pelvic Inflammatory Disease

Pelvic inflammatory disease (PID) is an infection of the uterus, ovaries, and other female reproductive organs. PID causes scarring in these organs. This can lead to infertility, ectopic pregnancy, pelvic pain, abscesses (a collection of pus), and other serious problems. PID is the most common preventable cause of infertility in the United States.
