Denial Code 12
Definition:
The diagnosis is inconsistent with the provider type.
What is Denial Code 12?
Denial Code 12 means the diagnosis submitted on the claim does not appear to match the type or specialty of the provider billing or performing the service.
Payers may compare the diagnosis with the provider's specialty, taxonomy, and enrollment information. If the payer does not expect that type of provider to diagnose or treat the reported condition under its rules, the claim may be denied.
This denial may also occur when the wrong provider, diagnosis, or taxonomy information is submitted.
A new patient visits an optometrist for redness, irritation, and discharge from both eyes. The optometrist performs a comprehensive eye examination, CPT 92004, and documents bilateral acute conjunctivitis.
During charge entry, the biller accidentally selects ICD-10 F41.1 – Generalized anxiety disorder instead of the documented ocular diagnosis.
The optometry practice submits the claim to Aetna Commercial. Aetna denies CPT 92004 with Denial Code 12, and remark code N130.
Remark Code N130: "Consult plan benefit documents/guidelines for information about restrictions for this service."
- Denial Code 12 means the diagnosis reported on the claim is inconsistent with the provider type.
- The rendering provider is an optometrist, but the claim was submitted with a behavioral health diagnosis as the primary diagnosis.
- The optometrist did not diagnose or treat generalized anxiety disorder during this encounter.
- The provider's actual documentation supports an ocular condition, so the behavioral health diagnosis was simply selected by mistake during charge entry.
- This is different from Denial Code 8. Code 8 means the procedure is inconsistent with the provider type, while Code 12 means the diagnosis is inconsistent with the provider type.
A Psychiatric Mental Health Nurse Practitioner (PMHNP) performs a psychiatric diagnostic evaluation, CPT 90791, for a patient with severe Bipolar I disorder, ICD-10 F31.13.
The clinician is properly licensed and holds the Psychiatric/Mental Health Nurse Practitioner taxonomy 363LP0808X. However, BCBS's provider master file still identifies the clinician only as a Family Nurse Practitioner under taxonomy 363LF0000X.
BCBS processes the behavioral health claim and denies it with Denial Code 12, and remark code N521.
Remark Code N521: "Mismatch between the submitted provider information and the provider information stored in our system."
- The diagnosis itself is clinically correct. The patient was evaluated for documented Bipolar I disorder.
- The PMHNP is also appropriately trained and credentialed to provide psychiatric care within applicable scope and payer rules.
- The problem is that the payer's provider profile does not reflect the clinician's psychiatric specialty.
- When BCBS compares the behavioral health diagnosis against the provider type stored in its system, it sees only a general Family Nurse Practitioner profile.
- This creates an apparent diagnosis-to-provider-type mismatch and can result in CARC Code 12.
- RARC N521 further tells us that information submitted for the provider does not match what the payer has stored in its provider database.
- Updating NPPES alone does not necessarily update BCBS. The payer's own credentialing/provider master file may also require correction.
A patient with prostate cancer is being treated by a urologic oncologist. The oncologist decides that a genomic prostate cancer test is medically necessary and signs the treatment plan ordering the test.
A Physician Assistant (PA) working with the oncologist completes the laboratory requisition. During claim submission, the laboratory accidentally reports the PA's NPI as the ordering provider instead of the oncologist's NPI.
The laboratory submits the molecular testing claim to UnitedHealthcare Commercial.
UnitedHealthcare denies the service with Denial Code 12, and remark code N574.
Remark Code N574: "Our records indicate the ordering/referring provider is of a type/specialty that cannot order or refer."
-
The test itself may be covered: The patient's prostate cancer diagnosis and genomic test may meet UnitedHealthcare's medical necessity requirements.
-
The problem is the ordering provider: The oncologist actually ordered the test, but the claim was submitted with the PA's NPI as the ordering provider.
-
The payer checks provider type: UnitedHealthcare's policy requires this particular genomic test to be ordered by an appropriate physician specializing in prostate cancer treatment.
-
The claim therefore looks incorrect: When UnitedHealthcare sees the PA listed as the ordering provider, its system determines that the provider type does not meet the requirement for this test.
-
Denial Code 12 tells us there is an inconsistency between the diagnosis/service and the provider type.
-
RARC N574 gives us the main clue: the payer does not accept the provider listed as the ordering/referring provider for this service.
Why Does Denial Code 12 Occur?
- The diagnosis does not match the provider's type or specialty.
- The wrong diagnosis code was submitted.
- The wrong rendering or billing provider was reported on the claim.
- The provider's taxonomy code is incorrect or outdated.
- The payer has the provider enrolled under a different specialty.
- The payer restricts treatment of the reported condition to certain provider types.
- The diagnosis is correct, but the payer's provider records are outdated or incorrect.
How to Avoid / Ways to Mitigate Denial Code 12?
-
Verify the Diagnosis: Make sure the diagnosis submitted accurately represents the condition documented by the provider.
-
Check the Provider: Confirm that the correct billing and rendering providers are reported on the claim.
-
Verify Provider Taxonomy: Make sure the taxonomy code accurately represents the provider's specialty and is correctly submitted.
-
Check Payer Enrollment: Verify that the payer has the provider enrolled under the correct specialty and provider type.
-
Review Payer Rules: Check whether the payer limits treatment of the condition to certain provider types or specialties.
-
Correct Payer Records When Necessary: If the diagnosis and provider information are correct, contact the payer to investigate incorrect enrollment or provider information.
