To do the test:
Occult blood in the stool may indicate colon cancer or polyps in the colon or rectum - though not all cancers or polyps bleed. Typically, occult blood is passed in such small amounts that it can be detected only through the chemicals used in a fecal occult blood test.
What Does the Blood in the Stool Look Like?
K92. 1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM K92.
K92. 1 - Melena | ICD-10-CM.
R19. 5 - Other fecal abnormalities. ICD-10-CM.
A fecal occult blood test (FOBT) looks at a sample of your stool (poop) to check for blood. Occult blood means that you can't see it with the naked eye. And fecal means that it is in your stool. Blood in your stool means there is bleeding in the digestive tract.
Melena refers to black stools that occur as a result of gastrointestinal bleeding. This bleeding typically originates from the upper gastrointestinal (GI) tract, which includes the mouth, esophagus, stomach, and the first part of the small intestine.

The fecal occult blood test (FOBT) is a lab test used to check stool samples for hidden (occult) blood. Occult blood in the stool may indicate colon cancer or polyps in the colon or rectum — though not all cancers or polyps bleed.
Occult: Hidden. For example, occult blood in the stool is hidden from the eye but can be detected by chemical tests.
If your FOBT results are positive, this means blood has been detected in your sample. About one in 14 people will have a positive FOBT result. Bleeding may be caused by a number of conditions, including polyps, haemorrhoids or inflammation, and may not necessarily be cancer related.
A stool test may also be referred to as a “stool sample,” a “stool culture” or “fecal sample.” This type of test looks at fecal matter for evidence of a medical condition. The test may look for evidence of infection, allergy, blood or digestive problems.
In patients who are taking non-steroidal anti-inflammatory drugs and have a history of gastrointestinal bleeding but no other signs, symptoms, or complaints associated with gastrointestinal blood loss, testing for occult blood may generally be appropriate no more than once every three months.
The guaiac-based test is the most widely used.
There are extra gastrointestinal causes such as hemoptysis, epistaxis, and oropharyngeal bleeding. Artifactual causes include hematuria, and menstrual bleeding. In addition, there may be other causes such as coagulopathies, gastrostomy tubes or other appliances, factitial causes, and long distance running.
Similarly, this test's sensitiv ity may result in a false positive if the patient has recently ingested meat.
