Provider was not certified/eligible to be paid for this procedure/service on this date of service.
A: This denial is received when the claim’s date of service is prior to the provider’s Medicare effective date or after his/her termination date, or when a procedure code is beyond the scope of the provider’s Clinical Laboratory Improvement Amendment (CLIA) certification, or a laboratory service is missing a required modifier.
Submit claims for services rendered when the provider had active Medicare billing privileges.
Review the Medicare Remittance Advice (RA), and verify the date of service.
• If the date of service is not correct, follow procedures for correcting claim errors.
• If the date of service is correct, there may be an issue with the provider’s Medicare effective or termination date.
• View enrollment information through the Internet-based Provider Enrollment, Chain and Ownership System (PECOS) and confirm provider’s Medicare effective date. Click here external link for more details.
Note: The provider’s Medicare effective date can be retroactive up to 30 days from receipt of application, or a future date, up to 60 days from receipt of application.
• If you require additional assistance, you may contact Provider Enrollment.
Submit claims for laboratory services within the scope of the provider’s CLIA certification.
• Verify service/procedure code is listed as approved under the scope of the provider’s certification
 Refer to the List of Waived Tests external pdf file from the CMS website to determine which codes require the modifier QW (CLIA waived tests).
• If the procedure code is not correct, or the procedure code modifier is missing, follow procedures for correcting claim errors.
Make the necessary correction(s), and resubmit the claim. Submit the corrected line only. Resubmitting the entire claim will cause a duplicate claim denial.
