Use AdditionalUse Additional Help
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.
Type 1 ExcludesType 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as K51. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Clinical Information
- An inflammatory bowel disease involving the mucosal surface of the large intestine and rectum. It may present with an acute or slow onset and follows an intermittent or continuous course. Signs and symptoms include abdominal pain, diarrhea, fever, weight loss, and intestinal hemorrhage.
- Chronic inflammation of the colon that produces ulcers in its lining. This condition is marked by abdominal pain, cramps, and loose discharges of pus, blood, and mucus from the bowel.
- Chronic, recurrent ulceration of the colon mucosa and submucosa.
- Inflammation of the colon that is predominantly confined to the mucosa. Its major symptoms include diarrhea, rectal bleeding, the passage of mucus, and abdominal pain.
- Ulcerative colitis is a disease that causes ulcers in the lining of the rectum and colon. It is one of a group of diseases called inflammatory bowel disease. Ulcers form where inflammation has killed the cells that usually line the colon. Ulcerative colitis can happen at any age, but it usually starts between the ages of 15 and 30. It tends to run in families. The most common symptoms are pain in the abdomen and bloody diarrhea. Other symptoms may include anemia, severe tiredness, weight loss, loss of appetite, bleeding from the rectum, sores on the skin and joint pain. Children with the disease may have growth problems. About half of people with ulcerative colitis have mild symptoms. Several types of drugs can help control ulcerative colitis. Some people have long periods of remission, when they are free of symptoms. In severe cases, doctors must remove the colon.
