K64: Haemorrhoids and perianal venous thrombosis

K64.8: Other specified haemorrhoids

"Other specified haemorrhoids" (K64.8) refers to conditions where the blood vessels in the rectal or anal region develop problems but don't fit the typical characteristics of the most common types of haemorrhoids. These could include haemorrhoids that come with unique symptoms or complications, or haemorrhoids that are located in unusual regions. Symptoms are generally similar to typical haemorrhoids and may involve discomfort, itching, or pain in the rectal area, and occasionally, bleeding during bowel movements. The causes for these specific haemorrhoids can vary but are frequently linked to increased pressure in the lower rectum, such as from straining during bowel movements or pregnancy. The progression and severity of these specified haemorrhoids depend on several factors, including underlying cause and individual health condition.
