Common Reasons for Claim Denials and How to Resolve Them

Submitting claims for reimbursement can sometimes result in denials due to missing or incorrect documentation. This guide outlines the most common reasons for claim denials and provides actionable steps to resolve them.

Overview of Required Documentation

To ensure your claim is processed successfully, include the following documents:

  • Proof of Coverage: Must include your name, plan name, premium amount (if applicable), and a current date (within the last 30 days). Acceptable documents include premium bills, policy summaries, or confirmation letters.

  • Itemized Receipts: Include the date of service, provider name, patient name, detailed service descriptions, and amounts paid. For medical treatments, a doctor’s note or letter of medical necessity may also be required.

  • Service-Specific Details: For psychotherapy claims, include the CPT code. For dental claims, provide an itemized receipt with a detailed description of services.

Common Reasons for Claim Denials

Missing or Incomplete Information

  • Proof of Coverage Issues: Claims are often denied if the proof of coverage lacks critical details such as the plan name, effective date, or premium amount. Ensure all required details are included in an official document.

  • Handwritten or Illegible Documents: Handwritten dates or illegible uploads are not accepted. Resubmit with clear, typed, or printed documents.

  • Pending Proof of Coverage: Claims may remain denied for 2–3 weeks while the compliance review process for recently submitted proof of insurance is completed. Ensure you allow sufficient time for this process before resubmitting.

Non-Compliant Submissions

  • Pre-Service Claims: Claims submitted before the service date will be declined. Wait until after the service date to submit.

  • Group Plan Documentation for ICHRA: ICHRA plans require proof of individual coverage, not group plans.

  • Non-Eligible Services: Certain services, such as couple’s or family therapy, may not be covered under your insurance plan. Verify your plan’s coverage details to confirm eligibility.

Document-Specific Issues

  • Changes in Policy Terms: Insurance policies, including FSAs, often update their terms annually. For example, a medication claim that was previously approved may now require additional documentation, such as a letter of medical necessity or an RX number. Always review your policy's latest terms to ensure compliance.

  • Non-English Receipts: Receipts not in English must be accompanied by a translated copy.

  • Recurring Premium Claims: Ensure the effective date and plan details are on an official carrier-issued document.

Steps for Resubmitting Declined Claims

  1. Review the Explanation of Benefits (EOB): Carefully read the EOB provided by your insurance carrier to understand the specific reason for the denial.

  2. Contact Your Insurance Carrier: Reach out to your insurance provider for clarification on the denial and guidance on next steps. Most carriers have dedicated customer service lines or online portals for member inquiries.

  3. Gather Required Documents: Ensure all missing or incorrect details are addressed.

  4. Resubmit Through the Portal: Upload the corrected documents via the claims portal.

  5. Appeal the Decision: If you believe the denial was made in error, follow your insurance carrier’s appeal process. This often involves submitting a formal appeal letter along with supporting documentation.

  6. Wait for Review: Once resubmitted, the claims team will review your documents and notify you of the decision.

Tips for Ensuring Approval

  • Always use official documents with clear, typed details.

  • Double-check that all required information is included before submission.

  • For medical services, ensure the receipt includes the actual date of service, not just the payment date.

  • If submitting for reimbursement of premiums, include a current document showing the premium amount and coverage period.

  • Check for annual updates to FSA terms or policy requirements, and provide any newly required documents, such as a letter of medical necessity.

  • Verify your plan’s coverage details to confirm eligibility for services like couple’s or family therapy.

  • Allow 2–3 weeks for the compliance review process after submitting proof of insurance before resubmitting.

By following these guidelines and ensuring your documentation meets the outlined requirements, you can minimize the risk of claim denials and expedite the approval process.
