Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Type 1 Excludes
Type 1 ExcludesA 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.
- necrotizing enterocolitis of newborn P77
Type 2 Excludes
Type 2 ExcludesA 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.
- angioectasia angiodysplasia duodenum K31.81
Patient Education
Digestive Diseases
When you eat, your body breaks food down to a form it can use to build and nourish cells and provide energy. This process is called digestion.
Your digestive system is a series of hollow organs joined in a long, twisting tube. It runs from your mouth to your anus and includes your esophagus, stomach, and small and large intestines. Your liver, gallbladder and pancreas are also involved. They produce juices to help digestion.
There are many types of digestive disorders. The symptoms vary widely depending on the problem. In general, you should see your doctor if you have:
- Blood in your stool
- Changes in bowel habits
- Severe abdominal pain
- Unintentional weight loss
- Heartburn not relieved by antacids
