Medicare & Medicaid Compliance

CaroMont Regional Medical Center Laboratory is dedicated to providing excellent service while complying with all laws and regulations pertaining to the delivery of and billing for services to federal and state government programs such as Medicare and Medicaid.

In an ongoing effort to ensure compliance with Centers for Medicare and Medicaid Services (CMS), CaroMont Regional Medical Center Laboratory has developed specific policies and procedures for the prevention of processes or practices that may result in billing errors or be viewed as fraudulent or abusive.

It is our goal to ensure that referring physicians and clients are informed of our policies. Your awareness and understanding of these policies will assist us in providing efficient, quality patient care while meeting our responsibilities as a provider of laboratory services.

Annual Notice to Physicians

Medical Necessity

Medicare is required by federal law to pay only for services it considers medically necessary to diagnose or treat an illness or injury or to improve the function of a malformed body member. As a result, Medicare often requires a specific diagnosis for certain laboratory tests before they will consider a test medically necessary.

Although physicians may order any tests they feel are necessary to diagnose and treat a patient appropriately, Medicare will only pay for those that meet the Medicare definition of medical necessity.

Therefore, all Medicare claims submitted by CaroMont Regional Medical Center must include complete medical necessity documentation using the ICD-10CM coding system to be compliant and eligible for reimbursement of services provided.

Physician and Client Responsibilities

It is the responsibility of the ordering physician and laboratory client to submit all clinically relevant ICD-10 codes for each test on the laboratory requisition at the time of the test order.

Patients presenting to CaroMont Regional Medical Center outpatient collection centers with laboratory orders from their physician lacking medical necessity documentation may experience a delay in services, or will be asked to sign an Advance Beneficiary Notice (ABN) accepting financial responsibility for tests which Medicare is likely to deny payment. Therefore, it is important that the laboratory requisition or physician order provides complete medical necessity documentation.

For specimens submitted to our Outreach Services department, the laboratory requisition accompanying the specimen should include all medical necessity documentation.

If medical necessity documentation is not submitted with the requisition or a valid ABN was not obtained, the charges for these services will be billed to the referring physician or client office.

Important Points to Remember:

  • ICD-10 diagnosis codes are the only acceptable form of medical necessity documentation.
    Narrative diagnoses are not acceptable.
  • ICD-10 codes submitted must be consistent with documentation in the patient record.
    When choosing an ICD-10 code, always select the code that most accurately describes the patient’s condition and code to the highest level of specificity.
  • Only physician office or client staff authorized and experienced with coding should provide ICD-10 codes for laboratory services.
  • Providing ICD-10 codes on the Laboratory Requisition will avoid unnecessary phone calls to physician and client offices as well as delays in service to patients, to obtain medical necessity documentation.
  • An ABN form must be submitted with each lab requisition when a limited-coverage test is ordered without an ICD-10 code supporting the medical necessity of the test.
  • Laboratory services provided through our Outreach Services department without medical necessity documentation or a valid ABN will be billed to the referring physician or client office.

Limited Coverage Tests

Medicare and local Medicare intermediary - Palmetto GBA, have established national or local medical review policies for specific laboratory tests. These policies include a list of diagnosis codes indicating what clinical circumstances justify the medical necessity of an individual test. In addition, these policies contain information including specific non-covered diagnosis codes, coding guidelines, reason for denial and frequency limitations.

CaroMont Regional Medical Center Laboratory discourages the use of any lists, “cheat sheets” or software containing commonly used ICD-10 codes by physician or client offices, especially for the purpose of ensuring coverage and reimbursement.

Routine Screening Tests

Routine screening test(s) are not a Medicare covered service unless specified in Medicare law. The patient will be financially responsible for payment of routine screening tests.

Advance Beneficiary Notice (ABN)

The intent and purpose of an ABN is to notify Medicare beneficiaries, in writing, that a test being ordered for them by their physician may not be paid for by Medicare. The beneficiary has the opportunity to make an informed decision about whether or not to have the test and be financially responsible should Medicare deny payment.

Medicare allows CaroMont Regional Medical Center to bill the patient for a denied test only if an ABN is completed and signed by the patient prior to specimen collection.

Routine or blanket ABNs are prohibited by Medicare where there is no reasonable expectation of non-coverage.

An ABN should be obtained when one or more of the following circumstances exist:

  • The diagnosis does not meet medical necessity guidelines.
  • The test(s) is for a routine exam or screening.
  • The test(s) is for experimental or investigational use.
  • The number of times the test(s) can be ordered within a certain time period is limited by Medicare.
  • The test(s) has not been approved by the Food and Drug Administration.
  • No diagnosis provided.

The ABN is not valid unless the following information is provided or completed:

  • Patient name and Medicare number
  • Description or test(s) that may be denied
  • Reason why service may be denied
  • Estimated test(s) cost – Contact Laboratory Client Services
  • Explanation to patient
  • Patient reads and checks Option Box
  • Patient signature and date
  • Provide patient a copy of completed and signed ABN for their records.
