Statutory Protection Verdict // 38 CFR § 3.951(a)
Your Existing Rating is Permanently Protected Under Federal Law
Under 38 U.S.C. § 1155 and 38 CFR § 3.951(a), the Department of Veterans Affairs is legally prohibited from reducing an established disability evaluation solely because the rating schedule has been modified.
"A disability which has been continuously rated at or above any evaluation of disability for 20 or more years for compensation purposes under laws administered by the Department of Veterans Affairs will not be reduced... Furthermore, no disability rating awarded under a prior schedule may be reduced solely because of the readoption or amendment of the rating schedule." (38 CFR § 3.951(a))
Key Takeaway for You: If you are already rated at 50% for Sleep Apnea (Obstructive, Central, Mixed), the VA cannot reduce your percentage to 0% when the new rule takes effect. Your rating is protected unless you file an open claim for increase and the VA independently proves sustained medical improvement under 38 CFR § 3.344.
