Fissure and fistula of anal and rectal regions (K60)

The ICD-10 code for fissure and fistula of anal and rectal regions (K60) categorizes conditions involving tears (fissures) and abnormal connections (fistulas) in the anal and rectal areas. These codes help specify whether the condition is acute or chronic, simple or complex, and which precise region is affected.

This section includes codes like K60.0 and K60.1, which cover acute and chronic anal fissures, commonly known as anorectal fissures or simply anal fissures. The general K60.2 code is used when the fissure is unspecified. For fistulas, a range of codes detail whether the anal fistula is simple or complex, such as K60.31 for a simple anal fistula or K60.32 for a complex one. The codes also differentiate anorectal fistulas and rectal fistulas with emphasis on whether they are initial, persistent, or recurrent. Synonyms like perianal fistula and suprasphincteric anal fistula align with specific codes such as K60.30. Accurate use of these K60 codes guides proper diagnosis, treatment planning, and documentation for conditions affecting the anal and rectal regions.

Instructional Notations

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.

  • fissure and fistula of anal and rectal regions with abscess or cellulitis K61

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • abscess or cellulitis of anal and rectal regions K61
  • anal sphincter tear healed nontraumatic old K62.81

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.

Rectal Fistula

An abnormal anatomical passage connecting the RECTUM to the outside, with an orifice at the site of drainage.

Rectum

The distal segment of the LARGE INTESTINE, between the SIGMOID COLON and the ANAL CANAL.
