455.5
ICD-9-CMThis code signifies the presence of external hemorrhoids that have developed a complication beyond simple inflammation or bleeding. Such complications can include ulceration, necrosis, gangrene, or infection, indicating a more severe presentation requiring specific medical attention. It differentiates from uncomplicated external hemorrhoids by the presence of these additional pathological changes.
Use this code when documentation clearly indicates external hemorrhoids accompanied by a specified complication such as thrombosis, ulceration, or infection. This code is appropriate when the physician's notes describe findings like a thrombosed external hemorrhoid, an ulcerated external hemorrhoid, or an external hemorrhoid with evidence of gangrene. The presence of a specific "other complication" must be explicitly stated or clearly implied by the clinical findings.
