A denial is a signal to get more precise
Start here when insurance says no. The goal is to understand the reason, check for fixable issues, and move toward the right next step instead of paying blindly.
What to do first
Use these steps in order before you decide the denial is final.
- Read the denial notice carefully so you understand what was denied and what deadline applies next.
- Check for obvious errors before assuming the denial is correct, including missing information or a mismatch between the service and the code used.
- Contact your insurance company and ask for the reason for the denial in clear language.
- Ask your doctor or care team for help, especially if the service was medically necessary or documentation was incomplete.
- Ask whether a different but accurate code could better reflect the medical need for the service.
- File an appeal when the denial is not the end of the story, and use the Insurance Appeals Playbook for the step-by-step appeal process.
Questions to ask after the denial arrives
These questions help you find out whether this is an error, a missing authorization, a coding issue, or a true appeal problem.
Denial reason
"Can you explain the denial reason in plain language and tell me whether there are any errors in the claim or paperwork?"
Fixable issue
"Is this denial related to missing authorization, missing records, or a coding issue that can still be corrected?"
Doctor support
"Can my doctor submit more records or explain the medical necessity if that would help?"
Coding check
"Is there a different valid code that better describes why this service was necessary?"
Appeal next step
"What is the deadline and process for filing an appeal if this cannot be fixed another way?"
