The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Other female pelvic inflammatory diseases

Non-specific codes like N73 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for other female pelvic inflammatory diseases:

  • Use N73.0 for Acute parametritis and pelvic cellulitis - BILLABLE CODE

  • Use N73.1 for Chronic parametritis and pelvic cellulitis - BILLABLE CODE

  • Use N73.2 for Unspecified parametritis and pelvic cellulitis - BILLABLE CODE

  • Use N73.3 for Female acute pelvic peritonitis - BILLABLE CODE

  • Use N73.4 for Female chronic pelvic peritonitis - BILLABLE CODE

  • Use N73.5 for Female pelvic peritonitis, unspecified - BILLABLE CODE

  • Use N73.6 for Female pelvic peritoneal adhesions (postinfective) - BILLABLE CODE

  • Use N73.8 for Other specified female pelvic inflammatory diseases - BILLABLE CODE

  • Use N73.9 for Female pelvic inflammatory disease, unspecified - BILLABLE CODE

Patient Education


Pelvic Inflammatory Disease

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

Gonorrhea and chlamydia, two sexually transmitted diseases, are the most common causes of PID. Other bacteria can also cause it. You are at greater risk if you:

  • Are sexually active and younger than 25
  • Have more than one sex partner
  • Douche

Some women have no symptoms. Others have pain in the lower abdomen, fever, smelly vaginal discharge, irregular bleeding, and pain during intercourse or urination. Doctors diagnose PID with a physical exam, lab tests, and imaging tests. Antibiotics can cure PID. Early treatment is important. Waiting too long increases the risk of infertility.
