Title 26 › Subtitle Subtitle K— Group Health Plan Requirements › Chapter 100— GROUP HEALTH PLAN REQUIREMENTS › Subchapter B— Other Requirements › § 9820
Starting with plan years beginning on or after January 1, 2022, your employer health plan must keep an accurate, public online directory of the doctors and facilities in its network. The plan has to verify and update that directory at least every 90 days, remove providers it can't verify, and post updates within 2 business days of getting new information from a provider. If you call to ask whether a doctor is in network, the plan must answer in writing within 1 business day and keep a copy of that answer in your file for at least 2 years. Printed directories must warn you that they were accurate only as of their publication date and point you to the online database. There's a real protection behind this: if the plan's directory or its phone response told you a provider was in network, but the provider was actually out of network, the plan can only charge you the in-network cost-sharing amount, and the visit counts toward your regular deductible and out-of-pocket maximum. Plans must also publish plain-language information about the rules against surprise balance billing and tell you which state and federal agencies to contact if a provider breaks those rules.
