What Is Creditable Coverage?
Creditable coverage is any prior health insurance that "counts" when you transition between plans. Under the ACA, creditable coverage matters less than it used to (since pre-existing conditions can't be excluded on ACA plans), but it's still relevant for employer plans, Medicare, and certain state programs.
What Counts as Creditable Coverage
- Employer-sponsored health insurance
- ACA marketplace plans
- Private ACA-compliant plans
- Medicare and Medicaid
- CHIP (Children's Health Insurance Program)
- COBRA
- Military/TRICARE coverage
- State high-risk pools
When Creditable Coverage Matters
- Medicare Part D: If you delay Medicare drug coverage and didn't have creditable drug coverage, you pay a permanent late enrollment penalty
- Employer plans: May count prior coverage toward satisfying any waiting period
- Some state programs: Continuous coverage requirements for special enrollment rights
Keep your proof. When you leave any health plan, request a certificate of creditable coverage. This documents your coverage dates and can be used to prove continuous coverage when enrolling in a new plan. Most insurers provide this automatically, but ask if you don't receive one.
