Denver is the largest healthcare hub in the Rocky Mountain region. Denver Health and National Jewish Health sit in Denver, while Children’s Hospital Colorado and the University of Colorado Anschutz Medical Campus anchor neighboring Aurora, alongside large systems such as UCHealth and HealthONE and a growing base of independent primary care, orthopedic, and behavioral health groups. Commercial payers are led by Anthem Blue Cross Blue Shield, Kaiser Permanente Colorado, UnitedHealthcare, and Cigna, each with its own prior authorization rules, modifier policies, and contract rates. Getting those wrong is how Denver practices quietly lose revenue.

Colorado’s payer landscape also differs from many states. Health First Colorado, the state’s Medicaid program, runs through Regional Accountable Entities (RAEs) under the Accountable Care Collaborative, which affects attribution, care coordination, and how Medicaid claims are routed. State law also sets deadlines for insurers to pay clean claims. Our AR follow-up team tracks aging claims against those rules and escalates early, so Denver practices spend less time chasing payers and more time with patients.
