A prior authorization can establish that the plan approved a requested service under specified conditions. The later claim still has to match those conditions and the member’s benefit on the date of service.
When an authorized expensive medicine claim denies, start by comparing the written approval with the claim rather than assuming the insurer “lost” the authorization.
- Authorization approval letter
- Authorization number
- Approved dates/visits
- Approved product/dose/units
- Claim/EOB
- Provider/facility
- Eligibility on date of service
- Network status
- Any claim mismatch
- Written reason for denial despite matching approval
Put the approval and claim side by side
Compare member, product, dose/units, dates, number of visits, site, rendering provider, diagnosis, benefit channel and authorization number. Identify the first mismatch.
If the provider omitted the authorization reference or billed a different product or units, ask whether a corrected claim is appropriate.
Check benefit and network changes on the date of service
Authorization does not necessarily override eligibility, network or benefit changes. Confirm the member was active and the site/provider met the plan’s requirements on the treatment date.
If insurance changed between authorization and treatment, determine which plan was responsible for the date of service.
If everything matches, challenge the payment decision
Ask the plan to explain in writing why a claim matching the authorization was denied. Provide the approval letter and claim details with the request for reconsideration or appeal.
Keep the authorization and denial together; this is exactly the kind of case where written records matter more than repeating the story by phone.
Use the source that actually controls your case
MedicineCostHelp can organize the problem, but the member-specific plan, payer decision, provider record or assistance program makes the actual determination. Keep written decisions, reference numbers and the documents that support the next step.
