Expert analysis: how this denial is overturned
A coordination-of-benefits denial means the plan believes another payer is primary, or it adjusted your claim based on what a prior payer did. These are ordering problems, not coverage refusals. The fix is to establish the correct order of benefits: confirm which plan is primary using your coverage dates and the standard COB rules, then provide the primary payer's explanation of benefits so the secondary plan can pay its share. Even though the dispute is administrative, it is still an adverse benefit determination subject to the full-and-fair-review requirement of 29 CFR 2560.503-1(h)(1), and you may request the basis the plan used under 29 CFR 2560.503-1(g)(1)(v). You generally have at least 180 days to appeal (29 CFR 2560.503-1(h)(3)(i)). Note that a pure benefit-ordering dispute usually does not involve medical judgment, so external review under 45 CFR 147.136 may not apply. Honest odds: COB denials resolve well once the correct primary EOB is on file.
