Abdominal actinomycotic infection

This code represents an infection of the abdominal cavity caused by bacteria of the Actinomyces genus. This chronic, suppurative infection typically manifests with abscess formation, fibrosis, and draining sinuses within the abdomen, often involving the bowel or peritoneum.

Use this code when documentation confirms an actinomycotic infection specifically located within the abdominal region. This diagnosis is often supported by microbiological culture results identifying Actinomyces species from abdominal tissue or fluid, or characteristic imaging findings (e.g., CT scan showing an abdominal mass with central attenuation and peripheral enhancement) in conjunction with clinical signs.

• Ensure the documentation clearly specifies the abdominal location of the actinomycosis to differentiate from other sites.
• Code any associated complications, such as abscesses (e.g., 567.29 for other peritoneal abscess) or fistulas, separately.
• Review pathology reports and microbiology cultures for definitive identification of Actinomyces and anatomical site.
