Sleep apnea is one of the most commonly rated VA disabilities, and also one of the most frequently contested during the claims process. The VA’s approach to sleep apnea claims has tightened in recent years, with increased scrutiny on service connection evidence and ongoing debates about rating criteria. Veterans pursuing a sleep apnea claim need to understand what the VA requires, what evidence builds the strongest case, and how the current rating formula works.
The Service Connection Challenge
The most difficult part of a sleep apnea claim is typically service connection — proving that the condition is related to military service. Sleep apnea is rarely diagnosed during active duty because service members often do not seek evaluation for sleep disruption symptoms until after separation. The VA accepts several routes to service connection: direct service connection (documented symptoms or diagnosis during service), secondary service connection (sleep apnea caused or aggravated by a service-connected condition such as PTSD, sinusitis, or rhinitis), and nexus letters from private physicians establishing the medical relationship between service and diagnosis.
What a Nexus Letter Needs to Include
A nexus letter is a physician’s opinion connecting a condition to military service. For sleep apnea, the nexus letter needs to: identify the physician’s credentials and how they are qualified to opine on the nexus question, review the veteran’s service records and post-service medical records, state the physician’s opinion that the service connection is at least as likely as not (the VA’s evidentiary standard), and explain the medical rationale for that opinion. Generic nexus letters that simply state a connection without explaining the medical basis do not carry meaningful evidentiary weight.
VA Sleep Apnea Rating Criteria
VA diagnostic code 6847 rates sleep apnea at 50 percent when a CPAP is required (the most common rating), 30 percent when persistent daytime hypersomnolence is present without CPAP requirement, 10 percent for asymptomatic but with documented sleep disorder breathing, and 0 percent for asymptomatic without current treatment. The 50 percent rating for CPAP use is the primary target for most veterans with diagnosed obstructive sleep apnea. A secondary condition like hypoxemia can increase the total rating when combined with the base sleep apnea rating.
Frequently Asked Questions
Can I get a higher rating than 50 percent for sleep apnea?
The maximum schedule rating for sleep apnea itself is 100 percent, reserved for chronic respiratory failure with tracheostomy or cor pulmonale. For most veterans, the 50 percent CPAP rating is the maximum practically achievable under the schedule. Additional compensation through TDIU, SMC, or secondary condition ratings can significantly increase total compensation beyond the base sleep apnea rating.
