ALS and Medicare: Eligibility and Enrollment Basics
If you have ALS and qualify for SSDI, Medicare entitlement generally begins the same month your SSDI benefits begin. The usual 24-month Medicare waiting period and five-month SSDI waiting period are waived for qualifying ALS claims. SSA determines eligibility and the entitlement date.
TL;DR:
SSA uses diagnosis code 3350 to identify ALS. If your Medicare start date appears incorrect, contact SSA to review the diagnosis and entitlement record.
Provide existing neurology records and test results supporting the diagnosis, plus the onset information SSA requests.
For power wheelchairs or scooters, Medicare requires a face-to-face exam, a written prescription, and an enrolled supplier. Certain power wheelchairs may require prior authorization.
Under Original Medicare, after the Part B deductible, Medicare generally pays 80% of the approved amount for covered equipment when the supplier accepts assignment. Other coverage may change your costs.
Original Medicare offers broad specialist access, while Advantage may restrict networks or require prior authorization; disabled beneficiaries under 65 should check state Medigap availability.

Why enrollment guidance matters
Who qualifies and why ALS cases are treated differently
Most people wait 24 months after SSDI starts before Medicare kicks in. ALS is an exception written into federal law. Public Law 106-554 eliminated that 24-month Medicare wait for people with ALS back in 2001, and the ALS Disability Insurance Access Act later removed the standard five-month waiting period for SSDI disability benefits in qualifying ALS claims. Together, these changes mean a person approved for SSDI due to ALS can start receiving disability payments and Medicare coverage far sooner than someone with most other conditions.
For people qualifying through SSDI due to ALS, Medicare enrollment is automatic when disability benefits begin. SSDI also has nonmedical eligibility requirements; SSA determines eligibility.
-
SSA uses diagnosis code 3350 to identify ALS.
-
The waiver applies only to medically determined ALS, not to other motor neuron diseases or similar conditions.
-
If your Medicare start date appears incorrect, contact SSA to review your diagnosis and entitlement record.
The waiting-period waiver is specific to qualifying ALS claims. Ask SSA about your individual eligibility and Medicare start date.
How to apply and trigger Medicare without losing time
Applying for SSDI is the first and most important step, since Medicare entitlement rides on that approval. The process has a few concrete stages.
-
File the SSDI application through the Social Security Administration, either online, by phone, or at a local field office.
-
Provide existing neurology records and test results supporting the diagnosis, plus the onset information SSA requests.
-
Ask SSA about any questions concerning your diagnosis or entitlement record.
-
Track claim status and watch for the Notice of Award, which confirms both SSDI approval and the Medicare start date.
-
Contact SSA promptly if the Notice of Award does not reflect immediate Medicare entitlement.
Medicare enrollment is automatic when SSDI benefits begin for people qualifying due to ALS. Contact SSA if your notice or Medicare start date appears incorrect.
Ask your treating clinician which existing records support the diagnosis and provide the information SSA requests.

What Medicare covers for ALS care
Once entitlement begins, coverage spans several parts of Medicare, each handling a different piece of ALS care.
-
Part A covers inpatient hospital stays and hospice care when a person’s prognosis and needs qualify.
-
Part B covers outpatient services, physician visits, and durable medical equipment (DME) such as wheelchairs, communication devices, and oxygen equipment.
-
Coverage for an ALS medication depends on the drug, how it is administered, and the applicable Part B rules or Part D plan formulary.
-
Medicare Advantage plans bundle Parts A and B, and usually Part D, through a private insurer, with different rules for referrals and provider networks.
Medicare coverage of equipment depends on medical necessity and the applicable coverage rules. For power wheelchairs or scooters, a face-to-face exam and written prescription are required. The supplier must be enrolled in Medicare. Certain power wheelchairs may require prior authorization. Ask the supplier whether it accepts Medicare assignment.
Under Original Medicare, after the Part B deductible, you generally pay 20% of the Medicare-approved amount for covered equipment when the supplier accepts assignment. Medicare Advantage costs and requirements can differ. Ask the supplier or plan why a request was denied and what documentation or review process applies. For Original Medicare, a supplier may resubmit a power-wheelchair prior-authorization request; payment-denial notices explain appeal rights.
Choosing between Original Medicare and Medicare Advantage
The choice between Original Medicare with a Part D plan and optional Medigap policy, versus a Medicare Advantage plan, shapes how easily a person with ALS accesses specialists and equipment.
-
Original Medicare paired with Part D and Medigap generally offers the widest access to specialists and DME suppliers without referral requirements.
-
Medicare Advantage plans often include extra benefits but may require prior authorization and in-network providers for equipment and specialist visits.
-
Medigap availability for people under 65 is not guaranteed nationwide. Medicare.gov notes that federal law does not require insurers to sell Medigap to disabled beneficiaries under 65, so access depends on state law.
-
Newly eligible disabled beneficiaries get specific enrollment windows for joining Medicare Advantage or Part D plans, separate from the general annual enrollment period.
Anyone under 65 considering Medigap should contact their State Insurance Department or local SHIP office directly, since availability and pricing vary considerably by state. For a plain-language comparison of how these two paths differ in practice, our Medicare Advantage versus Medicare Supplement guide walks through the trade-offs that matter most for ongoing specialist and equipment needs.
Common paperwork pitfalls and how to avoid them
Keep records organized and ask the relevant agency or plan about any unclear notices or requirements.
-
Review SSA correspondence and ask SSA about your Medicare start date if it appears incorrect.
-
Direct questions about diagnosis coding and entitlement records to SSA.
-
Keep existing neurology records, relevant test results, and the onset information SSA requests organized.
-
Ask the supplier or plan why a request was denied and what documentation or review process applies. Original Medicare prior-authorization non-affirmations are not themselves appealable; payment-denial notices explain appeal rights.
-
Reach out to SHIP or a Medicare insurance advisor the moment something looks delayed rather than waiting weeks for a callback.
Processing times and documentation requirements vary. Contact SSA, Medicare, or the applicable plan for guidance on your situation.

FAQ
What is amyotrophic lateral sclerosis (ALS)?
ALS, also called Lou Gehrig’s disease, is a progressive neurological condition that affects nerve cells controlling voluntary muscle movement. As it progresses, it affects a person’s ability to walk, speak, swallow, and eventually breathe without support. The ALS Association notes that early connection to SSDI and Medicare benefits is critical given how quickly needs can change.
How do I apply for Medicare?
For most people with ALS, you do not apply for Medicare separately. You apply for SSDI through the Social Security Administration, and once approved with ALS properly documented, Medicare entitlement starts automatically the same month SSDI benefits begin.
What should I check about Medicare coverage?
Check the coverage and provider rules that apply to your plan. Ask SSA about your disability claim and Medicare start date, and ask the supplier or plan about equipment coverage requirements.
Do you get disability for ALS?
ALS can meet SSA’s medical disability criteria, but SSDI also has nonmedical eligibility requirements, including sufficient recent work credits. SSA determines eligibility. Qualifying ALS claims are exempt from the usual five-month SSDI and 24-month Medicare waiting periods.
