What is a requirement for insured members to see a specialist under Medicare Supplement Insurance Plans?

The requirement for insured members to see a specialist under Medicare Supplement Insurance Plans involves the ability to see specialists without needing a referral. Unlike some managed care plans that require referrals, Medicare Supplement Insurance provides more flexibility. Members can see any specialist that accepts Medicare patients without the need for prior authorization or a referral from a primary care provider. This characteristic of Medicare Supplement plans allows beneficiaries to have greater autonomy regarding the healthcare providers they choose to consult.

The other options suggest restrictions or requirements that typically do not apply to Medicare Supplement plans, such as requiring referrals or prior authorizations, which can limit a patient's ability to access necessary specialized care.
