C&P Exam for Sleep Apnea Syndromes (DC 6847)

For sleep apnea syndromes (DC 6847), the C&P examiner completes the following Disability Benefits Questionnaire (DBQ):

• DBQ RESP Sleep Apnea (public PDF on VA.gov)

DBQs are Department of Veterans Affairs Form 21-0960 series documents. Public DBQs are hosted on benefits.va.gov. A handful are examiner-only and are not posted publicly.

The fields below are reproduced from the DBQ form the examiner completes for this diagnostic code. This is the structural map of the form, showing what the examiner is asked to measure, observe, and record. It is a factual reproduction of the public DBQ, not advice on how to answer.

The following tiers are reproduced from 38 CFR Part 4, the VA Schedule for Rating Disabilities. Toggle between the official VA criteria and a Plain English explanation.

Plain-English summaries are AI-generated to explain the official criteria. The official 38 CFR language is the binding legal standard. When in doubt, ask a VSO.

The counts below are aggregated from published Board of Veterans Appeals decisions for this diagnostic code, among issues the Board granted or denied (remanded issues are not included). Each row reports how often a given evidence type was discussed in the decision text, broken down by outcome. This is a factual aggregate of the public record, not a prediction or recommendation about any specific claim.

• VA examination: appeared in 12512 granted decisions (12419 denied; 24931 decided total)
• Service treatment records: appeared in 9138 granted decisions (11963 denied; 21101 decided total)

The themes below were extracted by clustering 500 grant-factor sentences from published Board of Veterans Appeals decisions for this diagnostic code. Frequencies indicate how often each theme appeared in the sample. This is a factual aggregate of the public record, not advice or strategy for any specific claim.
