VA math → how VA rates sleep apnea

How VA rates sleep apnea

VA rates sleep apnea syndromes (obstructive, central, or mixed) under diagnostic code 6847 in the respiratory schedule, at 0, 30, 50, or 100 percent. The level turns on how the condition affects your breathing and daily function, not on the diagnosis alone. The 50 percent level is assigned when the condition requires use of a breathing assistance device such as a CPAP machine.

38 CFR § 4.97 · DC 6847

What the rating schedule says

0%Asymptomatic but with documented sleep disorder breathing
30%Persistent day-time hypersomnolence
50%Requires use of breathing assistance device such as continuous airway pressure (CPAP) machine
100%Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or; requires tracheostomy

How the regulation is applied

The device requirement sets the 50 percent level

Under diagnostic code 6847 the 50 percent evaluation is assigned when the condition requires use of a breathing assistance device such as a CPAP machine. It is that requirement, stated in the rating schedule, that maps to 50 percent (38 CFR 4.97, DC 6847).

It combines with your other ratings

A sleep apnea evaluation is combined with your other service-connected ratings using the combined ratings table, not added to them. Combined does not mean added: see how VA combines ratings.

How this combines with your other ratings

VA does not add your ratings together, it combines them by remaining efficiency, so any single rating rarely changes your combined number as much as simple addition would suggest. See how VA combines ratings, or use the combined-rating calculator.

This explains what the rating schedule says. It is educational, not claims assistance: only a VA-accredited representative may help with the preparation, presentation, or prosecution of a claim (38 CFR 14.629). We do not advise how to obtain or increase a rating, and we determine nothing about any specific claim.
