Appeal Workflow

How the appeal process works

To appeal an adverse imaging determination, specific administrative and clinical actions must be executed. Compare the manual steps required to handle this yourself versus utilizing Remedy Support as your administrative surrogate.

Step 1: Identify the Review Organization

Triage Sequence

The Manual DIY Path

You must determine whether the denial came directly from your carrier or from a delegated utilization management vendor such as eviCore or Carelon. You must record the authorization tracking number, denial reason, reviewer name if provided, and the clinical guideline cited in the notice.

The Remedy Support Path

Our platform's intake flow programmatically parses your denial documents, automatically extracts tracking numbers, identifies the delegated reviewer (such as eviCore or Carelon), and maps the case to the target medical guidelines.

Step 2: Audit the Conservative Therapy Timeline

Triage Sequence

The Manual DIY Path

Imaging guidelines often require documented conservative management before approving an MRI or CT. You must pull dates, session notes, prescription records, and treatment summaries for physical therapy, chiropractic visits, medication trials, or activity modification completed before the scan request.

The Remedy Support Path

Our engine programmatically structures your conservative care records, converting your physical therapy sessions, pharmacological history, and chiropractic visits into an organized clinical timeline that directly satisfies insurance benchmarks.

Step 3: Isolate Clinical Red Flags

Triage Sequence

The Manual DIY Path

You must review physician notes for symptoms that support urgent imaging, including progressive neurological changes, trauma, cancer history, infection concerns, or other documented red flags. These findings can justify imaging without waiting for the usual conservative therapy window.

The Remedy Support Path

Our case analysis engine automatically scans and isolates critical neurological or diagnostic red flags, structuring arguments that legally bypass conservative care requirements under established medical standards.

Step 4: Compile the Appeal and File Directly

Triage Sequence

The Manual DIY Path

You must assemble the denial notice, physician order, office notes, conservative therapy records, imaging request details, HIPAA authorization, and carrier-specific representative forms into one complete packet. You must submit it to the carrier or delegated imaging review department through the designated appeal channel.

The Remedy Support Path

We compile your comprehensive Authority Packet, including carrier-specific representative forms, HIPAA disclosures, and the authorization materials required for your plan, and route the file to the review department through an accepted carrier channel.

Utilization Review Regulations

Ask for the criteria behind the denial

Under both federal ERISA standards and state insurance mandates (such as California Health and Safety Code § 1367.01 or New York Insurance Law § 4903), any denial based on medical necessity must be reviewed and signed by a licensed clinical peer. You maintain the statutory right to request the specific clinical criteria used to issue the denial and the credentials of the reviewing physician.
