For home health services, be as specific as possible regarding the number of hours requested per day, the usage of these hours, and the duration of the prescription. Next, state the patient’s diagnoses.  \nStep 2 : Using the language of the medical necessity definition outlined in the box below, state why the service is medically necessary. Example: “Jane Doe needs home health care services because I expect it to assist her in achieving maximum functional capacity in performing activities of daily living, such as bathing, eating, dressing, and personal hygiene.”  \nLegal Definition of Medical Necessity  \nUnder Pennsylvania Medical Assistance, a service is medically necessary if it meets any one of the following three standards:  \n1. The service or benefit will, or is reasonably expected to, prevent the onset of an illness, condition, or disability;  \n2. The service or benefit will, or is reasonably expected to, reduce or ameliorate the  \nphysical, mental, or developmental effects of an illness, condition or disability; or  \n3. The service or benefit will, or is reasonably expected to, assist the individual to achieve or maintain maximum functional capacity in performing daily activities taking into account both the functional capacity of the individual and those functional capacities that are appropriate for individuals of the same age.  \nUse all parts of the medical necessity definition which are relevant to your patient. Explain the specific medical problem or functional limitation that results from the patient’s diagnosis. You should give specifics about how the service requested will address the functional limitation.  \nStep 3 : Include Information about Parental Availability  \nIf applicable, include a paragraph about the availability of parents to provide the service requested. Home health services like nursing or home health aide may be denied if the insurer assumes a parent is available to provide the service in question. It will be helpful for you to state the parental availability that you considered when making the prescription for services.  \nTo the extent the nurse or home health aide will be working while a parent is present, it is  \nimportant to emphasize the services the patient needs that cannot be provided by the parent(s) .  \nParents may be unavailable to provide services for any number of reasons, including but not limited to tending to essential household duties and errands, physical or mental limitations of the parent, and taking care of other children in the home.  \nStep 4 : Give specifics which are helpful in expanding on the legal definition:  \n• Expand on each statement made in the letter to give supporting medical evidence where available. Evidence can be from your charts, from consultant letters, or from conversations with family members.  \n• With as much detail as possible, explain how it will prevent an illness or disability. Refer to medical articles or lectures. Review failed treatments. Consider information available to you about the patient, such as compliance with other regimens, family and home supports, or coping skills, which the insurer may not know. Be specific about goals.  \n• With as much detail as possible, explain how it will ameliorate the physical, mental, or developmental effects of the patient’s illness. Cite past successes with the treatment. Cite recent medical articles. Include letters from consultants. Review failed treatments and address the insurer’s suggested treatments. Be specific about psychological factors that are relevant to your chosen treatment. Provide information you have which a distant administrator may not know.  \n• With ","cbCaint1tcNp4s0X","https://ap.wps.com/l/cbCaint1tcNp4s0X","pdf",193548,"English","# Writing a Letter of Medical Necessity\n## Step 1: Identify the Physician and Requested Service\n## Step 2: Explain Why the Service Is Medically Necessary\n## Legal Definition of Medical Necessity\n## Step 3: Address Parental Availability (When Applicable)\n## Step 4: Expand With Supporting Medical Evidence\n## Step 5: Conclude With the Prescription and Consequences","[{\"question\":\"What should a physician include in the opening section of a medical necessity letter?\",\"answer\":\"Include who you are, how long you have known and treated the patient, the service being requested, the patient’s diagnoses, and—if relevant—home health details like hours per day, how the hours will be used, and prescription duration.\"},{\"question\":\"How should the physician explain why the requested service is medically necessary?\",\"answer\":\"Use the medically necessary standards from the legal definition and connect the requested service to the specific functional limitation or medical problem caused by the patient’s diagnosis.
