What is the time duration when a Medicare patient on ESRD's group health plan is considered the primary payer?

The correct choice indicates that a Medicare patient with End-Stage Renal Disease (ESRD) is considered to have their group health plan as the primary payer for a duration of 30 months. This timeframe begins from the month of the patient's Medicare entitlement due to ESRD. During this coordination period, the group health plan pays before Medicare, which is important for managing healthcare costs effectively for those individuals.

Understanding the coordination of benefits is crucial for healthcare access associates as it impacts billing and the financial responsibilities of both patients and providers. After the 30-month period, Medicare typically becomes the primary payer unless specific circumstances extend or modify this arrangement.
