Source-verified VASRD criteria
How VA rates this diagnostic code
These percentages summarize the regulatory criteria already mapped to this diagnostic code. They do not predict a Veteran's individual evaluation or establish service connection.
Severe inflammatory bowel disease that is unresponsive to treatment; and requires hospitalization at least once per year; and results in either an inability to work or is characterized by recurrent abdominal pain associated with at least two of the following: (1) six or more episodes per day of diarrhea, (2) six or more episodes per day of rectal bleeding, (3) recurrent episodes of rectal incontinence, or (4) recurrent abdominal distension
Moderate inflammatory bowel disease that is managed on an outpatient basis with immunosuppressants or other biologic agents; and is characterized by recurrent abdominal pain, four to five daily episodes of diarrhea; and intermittent signs of toxicity such as fever, tachycardia, or anemia
Mild to moderate inflammatory bowel disease that is managed with oral and topical agents (other than immunosuppressants or other biologic agents); and is characterized by recurrent abdominal pain with three or less daily episodes of diarrhea and minimal signs of toxicity such as fever, tachycardia, or anemia
Minimal to mild symptomatic inflammatory bowel disease that is managed with oral or topical agents (other than immunosuppressants or other biologic agents); and is characterized by recurrent abdominal pain with three or less daily episodes of diarrhea and no signs of systemic toxicity

Evidence information
When reviewing the criteria, useful evidence categories can include diagnosis and treatment records, objective testing identified by the schedule, documented frequency/duration/severity when the criteria use those concepts, and functional effects described in medical or lay evidence. The relevant evidence depends on the actual claim and medical facts.
VMC does not diagnose conditions, guarantee a percentage, or advise anyone to exaggerate symptoms.
