Medicare coordination of benefits
When a Kaiser Permanente Medicare-eligible member is not eligible for our Medicare Advantage plans, we will coordinate benefits with traditional Medicare.
When Medicare is the primary payer, you must bill Medicare directly for services through the Medicare crossover process.
Note: Do not bill Kaiser Permanente for claims that will crossover electronically. This creates duplicate billing or payment. Remember to check your Medicare explanation of payment form, Reason Code MA18.
When Kaiser Permanente has referred the service, we will provide payment for all covered balances.
