The Medical Necessity Letter: Advocating to Get Your Patients the Care They Need
Streamlining the physician’s pursuit of insurance coverage for supplemental screening
The Medical Necessity Letter, a legal document, is a powerful tool for cancer screening clinics. This Letter can be provided to a health insurance company by a medical professional—commonly the patient’s primary care physician (PCP) or OB-GYN in the case of female patients—to advocate for financial support on behalf of a patient. The Letter provides evidence that a decision regarding medical care has been made and that the care is clinically justified. It is not a simple suggestion. Based on the clinical evidence, the Letter includes a formal recommendation that an additional service is essential for the patient. Therefore, approval of coverage for the recommended service is expected by the insurance company.
What is considered a medical necessity?
A medical necessity is a specific service that may prevent the onset of an illness or disability, reduce or improve its effects, or maintain a patient’s ability to perform daily activities given age and baseline functionality.
For example, “without this breast ultrasound (or MRI) my patient is at a higher risk of delayed detection of breast cancer, which may result in a shorter life expectancy than that of her peers.”
Elements of a Medical Necessity Letter
A Medical Necessity Letter may include the following:
- Patient identification. Name, date of birth, insured’s policy number, group number (Medicare or Medicaid number), and date the letter was written.
- Physician identification. Name of treating physician and relationship to the patient.
- Date of most recent evaluation. When the patient was last examined by the doctor writing the letter.
- Medical determination. A specific finding that has led to the determination of medical need and the date of this diagnosis
- Procedure. A recommendation for specific procedure or treatment.
- Duration of treatment. A statement giving a recommended length of time for treatment.
- Pertinent medical history. Inclusion of any other medical history that supports the diagnosis and recommended treatment.
- Medical Necessity. Statement of why the recommended treatment is necessary. Specifically, it states how the recommendation will meet the patient’s need to prevent, diagnose, and/or cure the condition that endangers the patient’s function and well-being. If required, it may state that there is no equally effective recommendation that is less expensive.
- Summary statement. A brief, rational final argument that leaves no question as to what the recommendation is.
- Signature. The treating physician’s signature with their medical specialty, license number, and contact information.
- Supporting literature. A list of medically approved guidance documents that back up the recommendations made by the treating physician.
Where does the Medical Necessity Letter go?
To demonstrate the use of the Medical Necessity Letter, we’ll use radiology as an example.
After the patient goes through the exam, the radiologist writes or dictates a report based on his or her assessment and provides a recommendation for follow-up, if needed.
A letter is drafted that includes the elements of the radiology report that support the recommendation.
Once the letter is written, it is usually sent to the patient’s PCP, who consider the recommendation. If they agree, the PCP sends the letter to the insurance company for coverage approval.
Some clinics have worked with their referring community to send letters directly to the insurance company as appropriate. A copy can also be sent to the patient and documented in the patient’s record.
