Cardiology denials: appealing advanced-imaging, device, and PCSK9 denials

Cardiology denials gather around the expensive decisions — advanced imaging, implantable devices, PCSK9 inhibitors. They turn on appropriate-use and policy criteria, and they're answerable when the record maps to them.

Denials in cardiology center on advanced cardiac imaging (stress imaging, cardiac CT or MR, PET) screened against appropriate-use criteria, implantable devices (such as ICDs) judged against indication criteria, and PCSK9 inhibitors gated behind statin step therapy and LDL thresholds. ACC guidance and Medicare NCDs are the reference points; the denial typically flags a missing criterion rather than disputing the diagnosis.

Why these denials happen

Plans run advanced cardiac imaging through appropriate-use criteria, often via a radiology-benefit manager, and require the clinical indication to match. Device coverage (e.g., ICDs) is judged against indication criteria and, for Medicare, an NCD. PCSK9 inhibitors are gated behind a documented statin trial or intolerance and an LDL threshold. ACC/AHA guidance supports these for the right patients, so the appeal is usually about documenting the criterion the denial flagged.

The common denials

  • Advanced imaging denied against appropriate-use criteria — indication not documented to match.
  • Device (e.g., ICD) denied — indication criteria or the Medicare NCD conditions not established.
  • PCSK9 inhibitor denied for step therapy — statin trial/intolerance or LDL threshold not documented.
  • Site-of-care steering for an imaging study or procedure.
  • Prior authorization criteria for the study or device not met in the record.

Is it worth appealing?

Sometimes worth appealing

Worth appealing when the criterion is documentable: for imaging, map the clinical indication to the appropriate-use criteria; for a device, to the indication criteria or the Medicare NCD; for a PCSK9 inhibitor, to the statin trail (or intolerance) and the LDL threshold. A documented statin intolerance counts as a satisfied step. Where the record genuinely doesn't meet the criterion, completing the work-up first is the stronger move.

How to appeal

  1. 1

    Map imaging to appropriate-use criteria

    Document the clinical indication for the study and tie it to the appropriate-use criteria the plan or its radiology-benefit manager applies.

  2. 2

    Meet the device or NCD criteria

    For an implantable device, document the indication criteria and, for Medicare, the conditions of the applicable NCD.

  3. 3

    Document the PCSK9 step trail

    Show the statin trial, failure, or intolerance and the LDL threshold the policy requires; an intolerance counts as a met step.

Frequently asked

My cardiac stress imaging was denied — can I appeal?
Advanced imaging is screened against appropriate-use criteria. Document the specific clinical indication and map it to those criteria, then appeal the medical-necessity denial.
The plan wants a statin before my PCSK9 inhibitor. I can't tolerate statins.
A documented statin intolerance counts as having met the step. Record the intolerance and the LDL threshold the policy uses, and appeal on that basis.
