Get a current diagnosis of obstructive sleep apnea from a sleep study
Get the CPAP prescription, machine records, or treatment records showing ongoing use
Gather service records showing in-service sleep issues, snoring, gasping, fatigue, or witnessed apneas
Collect buddy statements from spouse, roommates, fellow service members, or family describing symptoms during and after service
Obtain a medical nexus opinion linking sleep apnea to service or to another service-connected condition
If claiming secondary service connection, show the sleep apnea is caused or aggravated by a service-connected disability
Common secondary conditions to document include PTSD, rhinitis, sinusitis, deviated septum, GERD, weight gain from service-connected conditions, and other airway or sleep-related disorders
Submit evidence of continuity of symptoms from service to the present
Include lay statements describing loud snoring, choking during sleep, daytime sleepiness, and witnessed breathing pauses
Use VA treatment records, private treatment records, and sleep clinic notes to support the claim
Make sure the nexus letter uses VA language such as “at least as likely as not”
Ensure the medical opinion explains the reasoning with facts from your record
File the claim with all supporting evidence at the same time
Respond quickly to any VA requests for exams or additional evidence
Attend the C&P exam and clearly describe symptoms, onset, and impact on daily life
Bring copies of your diagnosis, CPAP use, and symptom history to the exam
Do not minimize symptoms during the exam
If denied, review the reasons for denial and correct missing evidence
Submit a supplemental claim with new and relevant evidence if needed
Consider an accredited VSO, attorney, or claims agent for help with nexus evidence and claim strategy
