What proctitis ICD codes can I use?

If you're looking for proctitis ICD codes to use, there are a lot, so we'll list only six examples. The majority of them are for ulcerative proctitis. Here they are:

  • K62.7 - Radiation proctitis

This ICD-10 code is meant to be used on a patient confirmed to have radiation proctitis, a type of proctitis that emerged due to radiation therapy.

  • K51.20 - Ulcerative (chronic) proctitis without complications

This ICD-10 code is used on patients confirmed to have ulcerative proctitis, a type of proctitis resulting from ulcerative colitis. The proctitis also doesn't have any complications.

  • K51.211 - Ulcerative (chronic) proctitis with rectal bleeding

This is the same as Item 2, but this time, there is a complication: rectal bleeding.

  • K51.212 - Ulcerative (chronic) proctitis with intestinal obstruction

This is the same as Item 2, but this time, there is a complication: intestinal obstruction.

  • K51.213 - Ulcerative (chronic) proctitis with fistula

This is the same as Item 2, but this time, there is a complication: fistula, an abnormal passageway between organs.

  • K51.214 - Ulcerative (chronic) proctitis with abscess

This is the same as Item 2, but this time, there is a complication: an abscess emerged alongside the proctitis (or emerged because of the proctitis).

Sexually-transmitted diseases can also cause proctitis, so it's best to look for ICD-10 codes tied to those diseases.

Please note that proctitis is not the same as regional enteritis (Crohn's disease), even though they are similar problems affecting the digestive system tract.

Are these proctitis ICD codes billable?

Yes. All of the aforementioned proctitis-related ICD-10 codes are valid and billable.

Clinical information about proctitis

Proctitis is the term used to refer to an inflammation in the rectum, which is located at the lower end of the large intestine right before the anus.

How do inflammations emerge in the rectum? They can form if the rectum's inner linings, bacteria, and/or chemicals irritate it, or as a result of inflammatory bowel disease.

There are three types of proctitis, two of which have ICD-10 codes in the list we provided earlier. There's radiation proctitis, which results from radiation therapy. There's ulcerative proctitis, which can emerge from ulcerative colitis. And there is a proctitis caused by sexually-transmitted diseases, and we refer to this type of proctitis as infectious proctitis.

A person with proctitis will likely have the following symptoms:

  • The inflammations can make mucus and blood appear on poop
  • They will feel pain in the rectum, and the rectum might become swollen
  • They will have difficult bowel movement
  • They might have diarrhea or become constipated
  • They will also feel like they need to poop frequently

Synonyms include

  • Acute proctitis
  • Acute radiation proctitis
  • Chronic radiation proctitis
  • Perforating radiation proctitis
  • Chronic ulcerative proctitis
  • Nonspecific ulcerative proctitis
  • Ulcerative proctocolitis
  • Proctitis with unspecified complications
  • Proctitis with complications (ulcerative)
  • Inflammatory polyps due to proctitis

Commonly asked questions

Yes, but we don’t recommend using those because they are likely to be invalid for use as well.

Healthcare professionals will conduct blood tests, stool tests, and/or a proctoscopy, to mention a few.

Antibiotics, immunosuppressants (if it’s an autoimmune proctitis), and sulfasalazine (if it’s an ulcerative proctitis), to name a few.
