Sleep Apnea VA Rating: The CPAP Rule, PTSD Secondary, and What's Changing
Sleep apnea is one of the most valuable VA claims and one of the most commonly connected secondary conditions to PTSD. This guide covers the current rating criteria, the CPAP rule, how to connect it to PTSD, and what proposed rule changes could mean.
Current Rating Criteria (DC 6847)
Sleep apnea is rated under Diagnostic Code 6847 at 38 C.F.R. 4.97. The rating levels are based on the severity of the condition and what treatment is required.
The CPAP Rule
Under current criteria, CPAP use automatically qualifies for a 50% rating. This is one of the most straightforward rating criteria in the VASRD. Your sleep study shows obstructive sleep apnea, your doctor prescribes a CPAP, and you use it. That is a 50% rating. No ambiguity in the ROM measurement, no subjective examiner judgment. The evidence is binary: do you use a CPAP or not.
Secondary Connection to PTSD
Multiple published medical studies have established a link between PTSD and obstructive sleep apnea. The mechanism involves hyperarousal, disrupted sleep architecture, and autonomic nervous system dysregulation. Under 38 C.F.R. 3.310, if you have service-connected PTSD and you are subsequently diagnosed with sleep apnea, the sleep apnea can be rated as secondary to PTSD. This requires: a current sleep apnea diagnosis (via sleep study), a service-connected PTSD rating, and a medical opinion (nexus) linking the two.
Sleep apnea at 50% secondary to PTSD at 50% produces a combined rating of 75% (rounded to 80%). For a single veteran with no dependents, that is $2,102.15/month in 2026 versus $1,131.68/month for PTSD alone. The sleep apnea secondary adds $970.47/month, or $11,645.64/year.
Evidence for a Sleep Apnea Claim
A sleep apnea claim requires: a polysomnography (sleep study) showing obstructive sleep apnea, CPAP prescription and compliance records, buddy statements from spouse or partner describing observed apnea episodes (stopping breathing during sleep, loud snoring, gasping), and for secondary claims a medical opinion linking sleep apnea to the primary service-connected condition.
