This could include situations where the claim does not meet the specific requirements or limitations set by the jurisdiction.
  2. Payment Policies: Denial code P21 can also be triggered when the claim does not align with the payment policies established by the insurance company.

  3. Communicate with the Payer: If there are any uncertainties or disagreements regarding the denial, reach out to the payer for clarification. Discuss the specifics of the claim and inquire about any additional information or documentation that may be required to resolve the denial.
  4. Provide Additional Information: If requested by the payer, provide any additional information or documentation that supports the claim’s compliance with the jurisdictional regulations and payment policies. This may include medical records, accident reports, or any other relevant documentation.
