Why Your Request Was Denied

Insurance reviewers make decisions based only on what is submitted. If important details are missing, the reviewer may not be able to determine that the criteria are met. Common missing elements include prior treatments that were tried but not documented, physical therapy or conservative care history, outside testing or specialist evaluations, medication history from other providers, and functional limitations or severity of symptoms.

Many plans require lower-cost or less intensive treatments to be attempted before approving more advanced options — such as trying standard medications before specialty drugs, completing physical therapy before surgery, or using preferred formulary medications first. If prior treatments were completed years ago or at another clinic, documentation may not be available unless it is specifically requested and provided.

Coverage policies often specify which diagnoses qualify for a service. If the diagnosis code submitted does not align with those criteria, the request may be denied — even if the treatment is medically appropriate. In some cases, additional related diagnoses or comorbidities were not included even though they are relevant.

Some approvals depend on demonstrating how significantly the condition affects daily life. Documentation may need to show limitations in work or daily activities, reduced mobility or endurance, sleep disruption, inability to perform self-care tasks, or failure to improve with prior treatment. If symptoms are described in general terms without indicating impact, the request may not meet criteria.

Denials sometimes occur due to non-clinical issues: incorrect patient information, missing forms or signatures, submission to the wrong payer or processor, or coding errors and incomplete attachments.

Some treatments are excluded entirely or covered only under specific conditions. Coverage rules vary widely between plans, even within the same insurer. Examples include off-label medication use, experimental treatments, weight loss medications on plans that exclude them, or procedures deemed not medically necessary for the submitted diagnosis.

Many insurers use structured criteria and automated systems to evaluate requests. If the submitted information does not match expected patterns, the system may generate a denial before a human reviewer evaluates the case — even when the treatment is clearly appropriate.
