Overview
Under 38 CFR 4.124a, Diagnostic Code 8017, Amyotrophic Lateral Sclerosis (ALS) is rated at 100 percent.
Regulatory authority: 38 CFR 4.124a, DC 8017
This guide is educational only. RatingScope does not diagnose ALS, cannot determine service connection, and does not predict a VA decision. This provides the standard regulatory rule for ALS severity.
Percentage Guides
Select a pathway to see what the published criteria ask about, what records may clarify it, and what should not be assumed.
Standard rating for ALS.
Learn
Use these short guides to connect published terms with the records and observations that may clarify them.
Diagnostic Code 8017 lists a 100 percent schedular evaluation for amyotrophic lateral sclerosis (ALS).
Records to review: Neurology consultation reports confirming definitive ALS diagnosis based on clinical and electrodiagnostic criteria; EMG and nerve conduction studies showing widespread active denervation and reinnervation; Pulmonary function and speech-language pathology assessments.
Evidence
A confirmed medical diagnosis of Amyotrophic Lateral Sclerosis (ALS).
A diagnosis alone does not identify which percentage pathway applies.
The public DBQ shows the kinds of findings an examiner may record. A veteran may review it, or may share it with a private clinician, before a C&P exam. RatingScope does not tell any person what to submit.
