5 Recurring Reasons for Denials in Laboratory Claims

10-30% of Laboratory Claims are denied the first time after submission. This alarming factor leads to a significant loss in revenue.

Understand denials and implement prevention strategies.

AltuMED Medical Billing helps its clients overcome denials and achieve 97% FTPR. In 15+ years of medical billing, we have noted common denials for laboratory claims.

10% to 30% of lab claims are either denied or rejected the first time after submission.

1. Missing/wrong CLIA number

Independent labs must submit CLIA numbers by certification type.

  • Certificate of Waiver: CLIA certificate for waived tests only.
  • Certificate for Provider-Performed Microscopy Procedures: CLIA certificate for physician/midlevel/dentist microscopy only. This certificate permits the laboratory to also perform waived tests.
  • Certificate of Registration: CLIA certificate for moderate/high complexity testing until compliance survey.
  • Certificate of Compliance: A CLIA certificate is issued after compliance inspection.
  • Certificate of Accreditation: CLIA certificate based on accreditation by a CMS-approved organization.

2. CO-50, CO-57, CO-151, N-115 LCD/NCD Denials

CO-50, CO-57, CO-151, N-115 - Medical Necessity: An ICD-9 code(s) was submitted that is not covered under an LCD/NCD

Check the LCD or NCD prior to service to determine the patient’s eligibility for services. If service not in LCD guidelines, give patients ABN before tests.

3. 109/N104/190/N106 N538 Non-Covered by this Contractor

109/N104/190/N106 N538 - Check patient eligibility before submitting claims.

Refer to the Eligibility section

  • Refer to the Inpatient section for service during hospital/SNF stay.

4. M127 Medical Notes Missing

M127 Medical Notes Missing – The payer needs medical notes for the claim processing. Documentation Requirements: the following records need to be submitted to the payer:

  • Progress notes or office notes
  • Physician order or intent to order

5. CO 11 – Diagnosis Inconsistent with Procedure

CO 11 denial– Coding error with diagnosis.

That’s the first thing to check if you get this type of denial. Double-check that ICD-10 matches services and LCD/NCD policy. Knowing denial reasons aids in improving lab billing process.
