ICD-10 Code A54.85 – Gonococcal peritonitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A54.85 – Gonococcal peritonitis
What it is
A54.85 identifies peritonitis caused by Neisseria gonorrhoeae. Use it when the peritoneum is documented as infected by gonococcal disease.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include abdominal pain, tenderness, fever, and signs of peritoneal irritation when gonococcal infection involves the peritoneal cavity.
When to use this code
Use this code when the provider specifically documents gonococcal peritonitis or confirms peritonitis due to gonorrhea. It may apply in disseminated gonococcal infection with peritoneal involvement. If the record only says peritonitis without a gonococcal cause, check documentation.
Do not use for
Do not use A54.85 for nonspecific peritonitis, pelvic inflammatory disease, or other gonococcal infections without peritoneal involvement. If the etiology is not stated, code the documented condition instead.
Coding tip
Confirm that both the gonococcal cause and peritonitis are documented before assigning A54.85.
