This article is to reinforce the appropriate procedures for submitting 
claims under a member's Medicare supplemental plan (e.g., MedigapSecurity, 
Security 65®). Medicare supplemental claims that are not 
submitted correctly will be rejected.
How Medicare supplemental claims are processed
The Centers for Medicare & Medicaid Services (CMS) is the primary payer for 
Medicare supplemental claims. Independence, the secondary payer, uses the CMS 
crossover process to receive Medicare supplemental claims. As part of this 
process, CMS sends claims directly to Independence for members who have a 
Medicare supplemental plan.
After the claim has been adjudicated by CMS, Independence enforces a 30-day 
window from the Medicare remittance date (i.e., the date the claim was 
finalized by CMS). This 30-day window does the following:
- allows CMS sufficient time to crossover the claim to Independence and for 
Independence to complete secondary adjudication;
- prevents duplicate claims and ensures correct pricing.
Medicare supplemental claim rejections
Medicare supplemental claims may be rejected if the provider submits the 
Medicare supplemental claim to CMS and then submits it to Independence for 
payment prior to the end of the 30-day window. Providers receive rejections for 
these claims through the 277CA transaction (for migrated members), U277 
transaction (for non-migrated members), or Rejected Claims Report (for 
non-migrated member claims sent via a UB-04 claim form).
For more information

the appropriate guide  in the EDI 
section of our website. For more information about our member migration to

supplemental claims.
