Acute parametritis and pelvic cellulitis

This code signifies an acute inflammatory condition affecting the parametrium (connective tissue surrounding the uterus) and/or the pelvic cellular tissue. It represents a severe infection within the pelvic cavity, often a complication of gynecological procedures, childbirth, or ascending infections.

Assign this code when documentation clearly indicates an acute infection of the parametrial or pelvic cellular tissue. This typically presents with fever, pelvic pain, and signs of systemic inflammation, often following recent gynecological surgery, abortion, or postpartum.

• Differentiate from other pelvic inflammatory diseases (PID) which may have different anatomical involvements.
• Look for documentation specifying "acute" to ensure appropriate code selection over chronic conditions.
• Consider sequencing with an underlying cause (e.g., obstetric complication, post-procedural infection) if applicable.
