Coverage under prefix K3S

HDHP

HDHP (High-Deductible Health Plan) coverage means the member has a higher deductible than traditional plans, often paired with a Health Savings Account (HSA). Most services require the member to pay out-of-pocket until the deductible is met. Preventive care is typically covered before the deductible. Submit claims normally to the payer listed above.

Medicare Advantage

Medicare Advantage coverage under this prefix means the plan administers Medicare Part A and Part B benefits on behalf of CMS. These claims may have different processing rules than commercial claims, including different prior authorization requirements and appeal timelines. CMS timely filing rules (365 days) typically apply.

HMO

Under this HMO prefix, the member's coverage is limited to the plan's provider network. Care is coordinated through a primary care physician. Specialist visits require a referral from the PCP. When billing, confirm that the referring provider and the referral authorization number are included on the claim.
