A letter of medical necessity (LMN) is a piece of paper used to substantiate the need of an item of durable medical equipment. A medical necessity may be defined as a reasonable, necessary, and/or appropriate need, based on clinical standards of care. For Sleep Apnea patients, letters of medical necessity are usually written by a doctor's office and include appropriate details such as:
- Patient name
- Date of Sleep study
- Diagnosis of Sleep Apnea
- Statement indicating that the patient needs CPAP, BPAP, or APAP as "medical necessity".
- Pressure settings
- Physician contact information
- Other pertinent information applying to the patient's need
