Under HIPAA, creditable coverage allows what regarding preexisting condition waiting periods when enrolling in a new group health plan?

• A. Reduce the waiting period for coverage of a preexisting condition
• B. Eliminate all preexisting condition exclusions forever
• C. Have no effect on preexisting condition waiting periods
• D. Require medical underwriting despite creditable coverage

Answer: (A)

Creditable coverage reduces the time you must wait for preexisting conditions when you enroll in a new group health plan. The new plan must look at the creditable coverage you had in the 63 days before enrollment and subtract that amount from any preexisting condition exclusion. If you had enough creditable coverage, the waiting period can be shortened to zero. This protection helps maintain continuity of benefits when switching plans. It doesn’t guarantee eliminating all exclusions forever in every situation, and it doesn’t mean a plan will require medical underwriting simply because you had prior coverage. The key idea is that creditable coverage shortens, potentially eliminates, the preexisting condition waiting period depending on how much coverage you had recently.
