Female chronic pelvic peritonitis

This code represents a persistent inflammation of the peritoneum lining the female pelvic organs, excluding cases caused by tuberculosis. It signifies a long-standing or recurrent inflammatory process within the pelvic cavity, often leading to adhesions and chronic pain.

Use this code for female patients diagnosed with chronic pelvic peritonitis where the infectious agent is not identified as tuberculous. Documentation should clearly state "chronic pelvic peritonitis" and rule out a tuberculous etiology. This code is appropriate when the condition is ongoing or recurrent, rather than an acute episode.

• Ensure documentation explicitly states "chronic" to differentiate from acute pelvic peritonitis.
• Verify that tuberculosis has been ruled out; if present, use A18.17.
• Consider sequencing with codes for underlying causes of the chronic peritonitis, if known and documented.
