Under HIPAA, preexisting conditions may be excluded for up to how many months if you have 12 months of credible coverage?

• A. Six months
• B. Twelve months
• C. Eighteen months
• D. Twenty-four months

Answer: (B)

The key idea is how HIPAA limits preexisting condition exclusions through credible (creditable) coverage. Under HIPAA, the longest a plan can exclude a preexisting condition is 12 months. Creditable coverage can reduce that exclusion period, but it cannot exceed the 12-month cap. If you have 12 months of credible coverage, the maximum preexisting condition exclusion allowed is 12 months. That’s why twelve months is the correct choice. The other options are longer than the HIPAA cap or don’t reflect the standard limit for this scenario.
