🚨 THE PRIMARY INSURANCE PAID… SO WHY IS THE SECONDARY CLAIM STILL DENIED? 🤔💰
Welcome back to another medical billing lesson!
Last time, we talked about Coordination of Benefits (COB) and why knowing which insurance pays first matters.
But here’s where things get interesting…
✅ Primary insurance processed the claim.
✅ Payment was received.
❌ Secondary insurance rejected or denied the claim.
And now everyone’s wondering… WHAT HAPPENED?! 😩
Here’s something every billing professional should remember:
PRIMARY PAID ≠ CLAIM CLOSED!
Before submitting that secondary claim, ask yourself:
🔎 Did we verify the correct payer order?
🔎 Did we receive the primary payer’s EOB or ERA?
🔎 Were the primary payment amounts and adjustments reported correctly?
🔎 Does the secondary payer require us to submit the claim, or will it cross over automatically?
🔎 Have we verified the secondary payer’s filing requirements?
And here’s the BIG one:
💡 Having two insurance policies does NOT automatically mean two insurance payments!
Secondary payers coordinate benefits according to their coverage provisions and applicable COB rules.
At ELS Medical Billing Group, LLC, we believe effective revenue cycle management means following the entire claim—not just celebrating the first payment.
Because sometimes the revenue you’re looking for isn’t in a new patient appointment.
It’s sitting in an unresolved claim. 🎯
