Letter of Medical Necessity: A Guide for Families Transitioning from the NICU

After your child’s NICU stay, you'll be navigating a new routine at home, managing ongoing medical needs, and ensuring that your baby gets the best care possible. One essential tool that can help make this process easier is a letter of medical necessity.

You might be wondering: What is it? Why do I need one? And how do I ask for it? Don’t worry, we’ve got you covered. Here’s a simple guide to help you understand what this letter is, why it’s so important, and how to get it so you can focus on your baby’s well-being.

What Is a Letter of Medical Necessity?

A letter of medical necessity is basically a letter from your child’s doctor that explains why certain medical treatments, equipment, or therapies are needed for their health.

This letter is usually sent to insurance companies, schools, or other places that might need some solid proof that the treatment or service is essential for your child’s recovery or growth.

Think of it as a professional note from your child’s doctor that helps make sure your baby gets what they need, whether it’s special equipment, therapy, or medical support.

 

Why Do You Need a Letter of Medical Necessity?

When your baby leaves the NICU, you may find that they still need some extra care to continue their healing or growth at home. This could be things like:

  • Medical equipment (oxygen, feeding tubes, monitors, etc.)

  • In-home healthcare (nursing, respite)

  • Specialized therapies (speech therapy, occupational therapy, physical therapy)

  • Medications or treatments that need insurance coverage

Insurance companies and other providers often require proof that these things are medically necessary before they will approve coverage or financial help. That’s why the letter of necessity is important - not having one may result in a denial of services or procedures and may lead to delays in care.

Who Should You Request a Letter of Medical Necessity From?

You’ll want this letter to come from someone who knows your baby’s medical history inside and out. This could be:

  • Your baby’s pediatrician or primary care doctor

  • The neonatologist (specialist in newborn care) who cared for your baby in the NICU

  • Other specialists who have been involved in your baby’s care (e.g., pulmonologists, cardiologists, neurologists)

The key is that the doctor or specialist understands your baby’s ongoing needs and can clearly explain why certain equipment or services are needed. It’s totally okay to have a conversation with your doctor beforehand to make sure they’re on the same page.

How to Request a Letter of Medical Necessity

Requesting a letter of medical necessity can feel a little intimidating, but don’t worry —this is a common request. Healthcare providers are used to writing these letters and they understand it’s a necessary part of getting your child the right care. 

Here’s a simple step-by-step guide:

  1. Identify What’s Needed: Make a list of exactly what your baby needs, whether it’s a piece of medical equipment, therapy, or a treatment.

  2. Check With Your Insurance: Sometimes insurance companies have their own forms or guidelines for these requests. It’s helpful to check in with them so you can provide your doctor with everything they need upfront.

  3. Make the Request: Call your doctor’s office and ask for the letter. Let them know exactly what it’s for and why it’s so important. You might want to follow up with an email just to be sure everything’s clear.

  4. Provide Any Extra Documentation: If your insurance or another organization asks for extra paperwork (like medical records), make sure both you and your doctor have what’s needed.

  5. Follow Up: If you don’t get the letter within a week or two, don’t hesitate to call and check on the status of your request.
