Laboratory/Pathology Services - CAM 472HB
Description:
The purpose of this policy is to outline when it is appropriate to allow reimbursement for the physician component of certain clinical pathology services. This policy also addresses the processing of automated laboratory tests.
Policy Statement:
Professional Clinical Laboratory
It has been customary to recognize the physician component of certain clinical pathology services for separate reimbursement when it is inappropriate for the physician to bill the global service because the technical component was rendered by a technician or another physician who performed the technical component of the service only. The technical component represents the facility charge for administering a service: machinery, technicians and supplies required to perform the procedure. The professional component represents the physician’s charge for direct involvement in performing or interpreting the procedure performed. Examples of professional components that are appropriate for reimbursement would include:
-
Interpretation and report of a clinical pathology examination rendered by a physician who has no association with the laboratory that prepared the specimen.
The factors necessary for the recognition of such services for reimbursement would include:
-
The interpretation and report must be necessary for the appropriate evaluation and treatment of the patient (medically necessary).
-
The interpretation and report must have been requested by the attending physician (a request for consultation).
-
The interpretation and report must be based on the physician’s personal evaluation of the pathological specimen or the specific laboratory findings. The physician must provide a written report signed by the physician that documents the interpretation or opinion.
Professional components are not recognized for routine clinical pathology services when those services involve testing of clinical specimens by automated machinery when the machine generates the test result without the necessity for physician interpretations.
A professional component of a technical service can be recognized as appropriate for reimbursement under the following guidelines:
-
The interpretation of the result and a written report is medically necessary for the appropriate evaluation and treatment of the patient.
-
The interpretation and report has been requested by the attending physician.
-
The interpretation in the report is based on the physician’s personal evaluation of the pathological specimen or the specific technical findings.
-
The reporting physician creates a report that is specific to the individual patient’s technical findings and signs and dates that report.

Automated Multi Channel Chemistry Tests
Twenty-three common laboratory tests are classified as "automated, multichannel chemistry tests." The automated test list is based on the 19 tests that could be performed on the original automated chemistry analyzers. GGT, triglycerides, CPK and iron were added later. The current list of automated tests includes:
Albumin, alkaline phosphatase, AST, ALT, direct and total bilirubin, BUN, carbon dioxide, calcium, cholesterol, chloride, CPK, creatinine, glucose, glucose-6-phosphate dehydrogenase, GGT, LDH, phosphorus, potassium, total protein, sodium, triglycerides, uric acid and iron.
Regardless of the method used to perform the tests, whether by the automated or non-automated method, the allowance for the individual tests will be limited to the amount paid for the corresponding automated panel.
Medicare Coordination of Laboratory Services of the State of South Carolina:
The Omnibus Budget Reconciliation Act clarifies the mandatory assignment provision, which applies to laboratory services performed in a physician’s office. Assigned claims for clinical laboratory services are reimbursed at 100% of the approved amount with no coinsurance or deductible applied.
Physicians must accept assignment for clinical diagnostic laboratory services performed by the physician or under their supervision. Medicare will deny any clinical laboratory charges filed by a non-participating physician on non-assigned claims as non-covered.
Non-participating physicians who render a clinical laboratory service and other office services on the same date may file two separate claims. An example of this would be one accepting assignment for the clinical lab service and the other non-assigned claim for other services. This is the only instance where Medicare accepts two different assignment intentions for the same date of service.
As assigned laboratory claims are reimbursed at 100% of the approved amount, there is no coordinated payment. These charges should be submitted with a provider remittance and should be non-covered as paid in full by Medicare.
Claims that are submitted for coordination should always have an Explanation of Medicare Benefits or Provider Remittance attached. If either of these items is missing, charges should be non-covered for lack of Medicare information.
This medical policy was developed through consideration of peer-reviewed medical literature generally recognized by the relevant medical community, U.S. FDA approval status, nationally accepted standards of medical practice and accepted standards of medical practice in this community, Blue Cross Blue Shield Association technology assessment program (TEC) and other nonaffiliated technology evaluation centers, reference to federal regulations, other plan medical policies and accredited national guidelines.
