Hemorrhoids and perianal venous thrombosis (K64)

The ICD-10 code section K64 covers hemorrhoids and perianal venous thrombosis, which are conditions involving swollen veins in and around the anus causing discomfort and bleeding. These codes are used to classify varying severity and types of hemorrhoids as well as related complications.

This code section includes detailed subcodes identifying the degree of internal hemorrhoids, from K64.0 (first degree, or mild bleeding internal hemorrhoids) to K64.3 (fourth degree, involving irreducible prolapsed and strangulated hemorrhoids). Terms like "bleeding internal hemorrhoids" and "prolapsed internal hemorrhoids" correspond directly to these codes, helping coders select the precise diagnosis. Additionally, K64.4 refers to residual hemorrhoidal skin tags, known as anal or sentinel tags, while K64.5 codes for perianal venous thrombosis, also called thrombosed external hemorrhoids. Other less common hemorrhoids are covered under K64.8, and unspecified hemorrhoids fall under K64.9. Understanding these subcodes ensures accurate coding for conditions such as bleeding, prolapse, thrombosis, or skin tags related to hemorrhoids.

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Hemorrhoids

Swollen veins in the lower part of the RECTUM or ANUS. Hemorrhoids can be inside the anus (internal), under the skin around the anus (external), or protruding from inside to outside of the anus. People with hemorrhoids may or may not exhibit symptoms which include bleeding, itching, and pain.
