HMO / DHMO / Capitation Plan

A dental health maintenance organization, commonly referred to as a DHMO or capitation plan, is a managed care insurance model that requires enrolled members to select a primary dentist who provides all covered services. The insurance carrier pays the assigned dentist a fixed monthly fee per enrolled patient, known as the capitation rate, regardless of whether the patient visits the office or receives any treatment during that period. Covered preventive and basic services are typically included in the capitation payment, while major and specialty procedures are subject to a patient copayment schedule that specifies fixed dollar amounts the patient pays directly to the provider at the time of service.

DHMO plans generally carry lower premiums and no deductibles or annual maximums, making them attractive to cost-conscious patients and employers seeking affordable group coverage options. However, the trade-off is a significant restriction on provider choice and no out-of-network benefits except in emergency situations. From the provider's perspective, the capitation model shifts actuarial risk from the carrier to the dental practice. If enrolled patients collectively require more treatment than the combined capitation payments cover, the practice absorbs the financial loss. Conversely, if the enrolled population is generally healthy and requires minimal care, the fixed payments can be profitable. Evaluating the demographics, use patterns, and copayment schedule of a DHMO contract before signing is essential for financial viability.

For dental billing operations, DHMO patients require a distinct workflow compared to fee-for-service patients. Capitation payments arrive as bulk monthly disbursements based on enrollment rosters rather than individual claim adjudications. The billing team must reconcile the carrier's roster against practice records each month to verify payment accuracy, identify patients who have been assigned but never visited, and flag patients who have transferred but remain on the roster. Patient copayments collected at the time of service represent a significant revenue stream beyond the capitation payment itself. Practices that carefully track roster accuracy, monitor use rates, and enforce copayment collection maintain healthier margins on their capitated patient populations.
