SSDI 5-Month Waiting Period Exception for ALS

Individuals medically determined to have amyotrophic lateral sclerosis (ALS) do not have to serve the mandatory five-month SSDI waiting period. Under federal law, monthly cash benefits begin with the first full calendar month of disability rather than waiting until month six.

This exception makes ALS one of the few conditions exempt from the unpaid waiting period written into the Social Security Act. For other medical impairments, claimants must wait through five full consecutive calendar months before cash benefits begin. Federal legislation recognized the progressive nature of ALS and removed this delay so families can receive immediate financial support.

The Legislative Elimination of the Five-Month Delay

For decades, section 223(c)(2) of the Social Security Act (42 U.S.C. 423(c)(2)) required every worker approved for Social Security Disability Insurance (SSDI) to complete a five-month waiting period. During those five months, claimants received zero cash payments from the Social Security Administration (SSA). Because ALS progresses rapidly, this delay imposed severe financial hardship during the critical early stages of illness.

Congress resolved this problem by passing the ALS Disability Insurance Access Act of 2019 (Public Law 116-250), enacted in late December 2020. The statute amended section 223(a)(1) of the Social Security Act (42 U.S.C. 423(a)(1)), and SSA codified the rule at 20 CFR 404.315(a)(4)(ii). Under this regulation, the five-month waiting period does not apply to any individual medically determined to have ALS whose disability application was approved on or after July 23, 2020.

How Standard SSDI Differs from the ALS Exception

To appreciate the value of the ALS exception, it helps to understand how the standard SSDI system operates. Under 20 CFR 404.315(a)(4), ordinary claimants must complete five full consecutive calendar months of disability before entitlement to monthly cash benefits begins.

Under 20 CFR 404.316(a), standard disability benefits are payable starting with the first month following the completion of that waiting period. Those five months are never paid out retroactively. They represent a permanent gap in cash assistance.

For an ALS claimant, that entire five-month gap disappears. The claimant does not lose five months of payments. Entitlement to monthly cash payments attaches directly to the first full calendar month in which the claimant meets the disability criteria.

How SSA Calculates the First Month of Entitlement

While ALS claimants skip the five-month waiting period, they remain subject to SSA's standard calendar-month rule. Under 20 CFR 404.315 and SSA Program Operations Manual System (POMS) DI 10105.015, disability benefit entitlement can only begin with a month throughout which the individual was disabled.

The day of the month your disability begins dictates your initial entitlement date:

1. Disability onset on the first day of a month: If SSA determines your established onset date is April 1, April is a full calendar month of disability. Your cash benefit entitlement begins immediately in April.
2. Disability onset on the second day or later: If SSA establishes your onset date as April 14, April is only a partial month of disability. Under POMS DI 10105.015, a partial month does not meet the requirement of being disabled throughout the month. Therefore, your first month of cash entitlement begins on May 1.

Even without a five-month waiting period, an onset date that falls after the first day of a month pushes cash entitlement to the start of the following calendar month.

Immediate Medicare Coverage Under Section 226(h)

The cash benefit exception is only one part of the special protection Congress granted to ALS claimants. Under ordinary Title II rules (42 U.S.C. 426(b)), disabled workers must receive cash benefits for 24 months before Medicare Part A and Part B coverage begins. When combined with the standard five-month cash waiting period, most claimants wait 29 months from their onset date to get Medicare.

Congress eliminated that healthcare waiting period for ALS patients twenty years before it removed the cash waiting period. Under the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 (Public Law 106-554), lawmakers added section 226(h) to the Social Security Act (42 U.S.C. 426(h)).

Section 226(h) directs that an individual entitled to SSDI based on a medical determination of ALS is entitled to Medicare Part A and eligible to enroll in Medicare Part B beginning with the very first month of SSDI cash entitlement. There is zero waiting period for Medicare. As soon as cash benefits begin, Medicare coverage begins on the exact same date.

Fast-Track Approvals Under Compassionate Allowances

Eliminating statutory waiting periods does not help claimants if their paperwork sits in an agency backlog for a year. To prevent delays, SSA classifies ALS as a Compassionate Allowance condition under POMS DI 23022.010.

The Compassionate Allowances initiative uses electronic screening to identify severe medical conditions that clearly meet statutory disability standards. When an applicant submits an SSDI application noting a diagnosis of ALS, the computer system flags the file for expedited processing and routes it directly to senior examiners.

The medical criteria for ALS are set forth in the SSA Blue Book at 20 CFR Part 404, Subpart P, Appendix 1, Listing 11.10. Under Listing 11.10, an applicant qualifies for disability benefits based strictly on a confirmed clinical diagnosis of ALS. SSA does not require proof of advanced muscle weakness, respiratory distress, or severe physical limitations.

A medical report from a licensed physician, typically a board-certified neurologist, confirming a clinical diagnosis of ALS through electromyography, nerve conduction studies, or clinical neurological examination satisfies Listing 11.10. Because the medical standard is concise, SSA frequently adjudicates ALS claims in several weeks rather than several months.

Retroactive Cash Payments for ALS Claimants

The elimination of the five-month waiting period also changes how retroactive benefits are calculated when an individual applies after their disability began. Under 20 CFR 404.621(a)(1), SSDI cash benefits can be paid retroactively for up to 12 months prior to the month of application.

In a standard SSDI claim, a person who became disabled 17 months before applying can only receive 12 months of retroactive cash. The first five months after onset are consumed by the mandatory waiting period under 20 CFR 404.315(a)(4).

For an individual diagnosed with ALS, no waiting months are subtracted. If an ALS claimant stopped working and was disabled 12 full calendar months before submitting an application, all 12 prior months are fully payable as past-due benefits. The absence of the five-month penalty ensures that every eligible month within the 12-month statutory lookback period results in a cash payment.

Family Auxiliary Benefits Begin Immediately

When an insured worker qualifies for SSDI, certain family members may also receive monthly auxiliary benefits on the worker's earnings record. Under 20 CFR 404.330, a spouse may qualify if caring for the worker's child who is under age 16 or disabled. Under 20 CFR 404.350, unmarried dependent children under age 18 (or up to age 19 if attending secondary school full-time) also qualify for auxiliary payments.

Because auxiliary benefits are linked directly to the primary worker's entitlement, the elimination of the worker's waiting period flows directly to the family. Family members do not have to wait five months for their auxiliary checks. Their monthly payments begin in the exact same month the worker's cash entitlement takes effect, subject to the family maximum benefit rules under 20 CFR 404.403.

Payment Scheduling and the Standard One-Month Delay

Claimants must distinguish between the calendar month for which benefits are owed and the date the payment actually arrives in a bank account. Under SSA Publication No. 05-10029 (July 2026 edition), Social Security disability payments are issued in the month following the month for which they are earned.

For example, if an ALS claimant's cash entitlement begins for the month of October, the payment for October is distributed in November. SSA schedules monthly payments based on the beneficiary's birth date under 20 CFR 404.1807:

1. Birth dates on the 1st through the 10th: Payments arrive on the second Wednesday of each month.
2. Birth dates on the 11th through the 20th: Payments arrive on the third Wednesday of each month.
3. Birth dates on the 21st through the 31st: Payments arrive on the fourth Wednesday of each month.

This one-month delay is an ordinary banking schedule, not a waiting period. The beneficiary receives full payment for every month of entitlement.

Frequently Asked Questions

Does someone diagnosed with ALS have to wait five months for SSDI cash payments? No. Under Public Law 116-250 and 20 CFR 404.315(a)(4)(ii), the statutory five-month waiting period is completely eliminated for individuals medically determined to have amyotrophic lateral sclerosis whose applications were approved on or after July 23, 2020.

When did the five-month waiting period exception for ALS take effect? Presidential enactment occurred in late December 2020 under the ALS Disability Insurance Access Act of 2019, which applied retroactively to ALS claims approved on or after July 23, 2020.

Does the ALS exception also eliminate the 24-month Medicare waiting period? Yes. Under section 226(h) of the Social Security Act, Medicare Part A and Part B begin in the very first month of SSDI cash benefit entitlement, entirely waiving the standard 24-month wait.
