The digestive diseases schedule of ratings is being updated because the current one is subjective and leads to inconsistent ratings. They say it's due for final ruling in May 2023. You will want to read the current schedule of ratings and compare it to the new one to see if you should try to drag your MEB out until they're published.
Here's the new proposed ratings:
According to the Truelove and Witts criteria, mild symptomatology involves fewer than four bowel movements per day with infrequent rectal bleeding; severe symptomatology involves six or more bowel movements per day with frequent rectal bleeding. VA therefore proposes to assign a 10-percent evaluation for minimal or mild symptomatic disease that is managed with oral or topical agents (other than immunosuppressants or other biologic agents) and is characterized by recurrent abdominal pain with 3 or less daily episodes of diarrhea and no signs of systemic toxicity.
VA proposes a 30-percent evaluation for mild to moderate disease, with recurrent abdominal pain, with 3 or less episodes of diarrhea per day, minimal signs of toxicity (fever, tachycardia, or anemia), and symptoms managed with topical or oral agents.
VA proposes to assign a 60-percent evaluation for moderate disease with recurrent abdominal pain, 4 to 5 daily episodes of diarrhea, and intermittent signs of toxicity (such as fever, tachycardia, or anemia), and requiring immunosuppressants or other biologic agents on an outpatient basis.
