Health Insurance Denial Lawyer for Employer Plans

If your employer health plan denied coverage for treatment, surgery, or care, you may have the right to appeal under ERISA.

When Your Health Insurance Claim Is Denied

A denied medical claim can leave you facing unexpected costs or delays in care. Many employees assume their employer-sponsored health plan will cover necessary treatment, only to receive a denial based on plan terms or insurer review.


Davis Olszeski Law represents individuals dealing with denied health insurance benefits under ERISA. Clients in St. Louis and surrounding areas often seek guidance when coverage for procedures, treatments, or ongoing care is denied and the next step is unclear.


What to Do After a Health Insurance Denial

Taking the right steps early can help you challenge a denial and avoid gaps in coverage.

Review the Explanation of Benefits (EOB)

The EOB and denial letter explain why the claim was denied and what the plan requires for approval.

Calendar the Appeal Deadline

Employer-sponsored health plans governed by ERISA typically require appeals within a defined timeframe.

Request Plan Documents and Claim File

These documents outline your rights and show how the decision was made.

Gather Medical and Supporting Records

Treatment records, physician recommendations, and supporting documentation can help address the denial.

Prepare a Complete Appeal Submission

The appeal should directly respond to the insurer’s reasoning and include all relevant evidence.


How ERISA Applies to Employer Health Plans

Many employer-sponsored health insurance plans are governed by ERISA. This federal law sets the rules for how claims are reviewed and how appeals must be handled.


If your coverage comes through your employer, ERISA likely applies. This means:


  • You must follow the plan’s internal appeal process
  • The plan must provide a structured review of your claim
  • The appeal record becomes important if the dispute continues


Understanding this framework helps ensure your appeal follows the correct process.


Stages of a Health Insurance Appeal

Appealing a denied health insurance claim typically involves several steps:


  • Initial Claim Decision
    The plan reviews your request for coverage and issues a denial if requirements are not met.


  • Internal Appeal
    You submit an appeal with additional documentation addressing the denial reasons.


  • Review by Plan Administrator
    The plan re-evaluates the claim based on the appeal submission.


  • Next Steps if Denied Again
    If the denial is upheld, additional review options or legal action may be available depending on the plan.

What Documents Help Support a Health Insurance Appeal

A well-prepared appeal includes documentation that clearly supports the need for coverage. Common materials include:


  • Explanation of Benefits (EOB)
  • Denial letters
  • Medical records and treatment history
  • Physician recommendations or letters
  • Plan documents outlining coverage terms


Submitting a complete and organized record helps ensure the plan evaluates all relevant information.


Common Reasons Health Claims Are Denied

Health insurance claims may be denied for a variety of reasons, including:


  • Treatment deemed not medically necessary
  • Services considered out-of-network
  • Missing or incomplete documentation
  • Disputes over coverage under the plan terms


Understanding the reason for denial helps guide how the appeal should be prepared.
