Under HIPAA, an individual's 'creditable coverage' is used to:

Why A is correct

HIPAA's portability rules limit the impact of preexisting condition exclusions when a person moves between group health plans. Prior coverage under another employer plan, COBRA, Medicaid, Medicare, or certain other arrangements counts as creditable coverage and is credited against the new plan's preexisting exclusion period, so the exclusion cannot exceed the coverage the person has already satisfied. If the individual maintains continuous coverage without a significant gap, the new plan may impose little or no exclusion at all. This portability of prior coverage is the centerpiece of HIPAA's group market protections and is tested directly on the A&H exam.

Why the other options are wrong

• B) HIPAA portability concerns continuity of health coverage from plan to plan. Cash values are a life insurance concept and have nothing to do with HIPAA's group health rules.
• C) HIPAA credits prior coverage against preexisting exclusions; it does not forgive premiums the employee owes under a new employer's plan, which remain the employee's responsibility.
• D) Medicare work credits are earned through covered employment and payroll taxes over a lifetime. They are unrelated to HIPAA creditable coverage for health insurance portability.

HIPAA credits = your old coverage carries over like store credit against the new plan's waiting period.

Why A is correct

HIPAA's portability rules ensure that a person who keeps continuous health coverage does not lose protection when moving between plans or jobs. Prior coverage that counts as 'creditable coverage' is credited toward any preexisting condition exclusion period a new plan would otherwise impose, so the remaining exclusion is shortened or eliminated entirely. The employer must provide a certificate of creditable coverage when coverage ends. This portability framework, part of the group legislation tested under the A&H outline, is what makes changing jobs less dangerous for people with existing health conditions.

Why the other options are wrong

• B) HIPAA protects continuity; the individual's new coverage rights are preserved rather than lost.
• C) Creditable coverage offsets the new exclusion period rather than restarting it.
• D) HIPAA portability concerns job-based health coverage, not Medicare enrollment.

Memory hook

Prior coverage is time served — creditable coverage shrinks the new plan's exclusion.
