Present on Admission (POA)
Q45.8 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

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
