Ulcerative colitis follows a bimodal age distribution, with peak incidence in young adults and a second peak between 50 and 70 years. That second peak matters. Elderly-onset UC carries all-cause mortality seven times higher than younger-onset disease, along with substantially elevated rates of C. difficile infection, colorectal cancer, and VTE. It is a different clinical challenge — harder to distinguish from mimics, more dangerous when undertreated, and more sensitive to immunosuppression risks. Nearly a million Americans are living with UC, and a growing share of them are in the Medicare population.
AAVBC's Ulcerative Colitis Quick Reference Guide gives primary care clinicians a structured reference for managing UC across the full disease course. It covers disease extent classification, ICD-10 subsite and complication coding, therapy escalation, steroid-sparing strategies, VTE and colorectal cancer surveillance, extraintestinal manifestation documentation, and MEAT documentation standards — grounded in current ACG and AGA 2025 Living Guideline evidence.
AAVBC’s Deep-Dive series offers a comprehensive, structured analysis of ulcerative colitis — moving far beyond quick-reference essentials. These guides provide an integrated review of epidemiology, diagnostic strategy, staging, coding logic, MEAT-aligned documentation examples, treatment guidelines, review vulnerabilities, and cost-utilization considerations. The Deep-Dive combines evidence-informed clinical guidance with practical operational tools to support a deeper understanding of disease complexity and provide multidisciplinary teams with strategies to thrive within value-based frameworks.
