- Diseases of the digestive system
- K51 (Ulcerative colitis) > K51.8 (Other ulcerative colitis) > K51.818 (Other ulcerative colitis with other complication)
In simple words: This code is used when someone has ulcerative colitis (a type of inflammatory bowel disease) along with other problems that aren't specifically mentioned in other codes. The doctor will also use another code to specify the extra problem.
This code signifies other forms of ulcerative colitis accompanied by complications not specifically listed elsewhere.It is crucial to utilize supplementary codes to pinpoint any accompanying manifestations, for example, pyoderma gangrenosum (L88).
Example 1: A 45-year-old female patient presents with a history of ulcerative colitis experiencing a severe exacerbation along with the development of toxic megacolon.K51.818 is used to code the ulcerative colitis and additional codes are used to specify the toxic megacolon., A 30-year-old male patient with a known diagnosis of ulcerative colitis develops severe anemia secondary to chronic blood loss from the rectum. K51.818 is utilized, along with codes for anemia and rectal bleeding., A 60-year-old patient with ulcerative colitis presents with a perianal abscess requiring surgical intervention. K51.818 is used, accompanied by codes for the abscess and the surgical procedure.
Complete medical history, physical examination findings, results of laboratory tests (e.g., complete blood count, inflammatory markers, stool studies), imaging studies (e.g., colonoscopy, CT enterography, MRI enterography), and any other relevant diagnostic procedures.Documentation must clearly link the ulcerative colitis to the reported complication.
** This code is used for cases of ulcerative colitis where the complications are not specifically listed.Accurate coding relies on thorough documentation to clarify the specific complications.
