Secondary claims

Conditions you can claim secondary to service-connected sleep apnea

Untreated OSA damages the cardiovascular, metabolic, neurologic and psychiatric systems, and each downstream condition can be rated on its own — provided the medical link is documented.

What a secondary claim requires

  1. 1A current diagnosis of the secondary condition.
  2. 2An already service-connected primary disability — here, obstructive sleep apnea.
  3. 3A medical nexus opinion stating the secondary condition is "at least as likely as not" caused or aggravated by the sleep apnea.

Mental health and neurologic

Depression

DC 9434

Fragmented, non-restorative sleep is strongly associated with depressed mood, anhedonia and impaired concentration — and CPAP intolerance often deepens it.

Depression secondary to sleep apnea

Anxiety disorders

DC 9400

Nocturnal arousals, choking sensations and chronic sympathetic activation both cause and aggravate anxiety symptoms.

Anxiety and PTSD nexus letters

Migraines and headaches

DC 8100

Morning headaches from nocturnal hypercapnia are a classic OSA finding, and OSA is a documented aggravator of migraine frequency.

Headaches secondary to sleep apnea

Cognitive impairment / memory loss

DC 8045

Sleep fragmentation and hypoxia impair attention, executive function and memory consolidation.

Central sleep apnea and TBI

Cardiovascular and metabolic

Hypertension

DC 7101

Repeated apneic episodes trigger sympathetic surges and nocturnal blood pressure spikes. OSA is one of the most recognized causes of secondary and treatment-resistant hypertension in the medical literature.

Type 2 diabetes mellitus

DC 7913

Intermittent hypoxia and sleep fragmentation impair glucose tolerance and increase insulin resistance, and untreated OSA worsens glycemic control in veterans already at risk.

Coronary artery disease

DC 7005

Chronic oxygen desaturation, oxidative stress and inflammation accelerate atherosclerosis and raise the risk of ischemic heart disease.

Atrial fibrillation and arrhythmias

DC 7010 / 7011

Nightly intrathoracic pressure swings stretch the atria and provoke bradyarrhythmias, atrial fibrillation and other nocturnal rhythm disturbances.

Stroke and residuals

DC 8007

Moderate-to-severe OSA is an independent risk factor for cerebrovascular accident, and stroke residuals are ratable separately.

Other body systems

GERD

DC 7206

Negative intrathoracic pressure during obstructed breaths pulls gastric contents upward, and reflux and OSA reinforce each other bidirectionally.

Sleep apnea and GERD

Erectile dysfunction

DC 7522

Reduced nocturnal oxygenation lowers testosterone and impairs endothelial function — often supporting special monthly compensation (SMC-K).

How the VA rates sleep apnea (38 CFR § 4.97, DC 6847)

Your underlying OSA rating stays in place while secondary conditions are rated separately and combined.

VA disability rating criteria for sleep apnea syndromes, 38 CFR 4.97, diagnostic code 6847
RatingCriteria
0%Asymptomatic but with documented sleep disorder breathing.
30%Persistent day-time hypersomnolence.
50%Requires use of a breathing assistance device such as a CPAP machine.
100%Chronic respiratory failure with carbon dioxide retention, cor pulmonale, or requires tracheostomy.

Working the other direction

If sleep apnea itself isn't service connected yet, start with the primary pathways — PTSD, sinusitis, rhinitis, obesity and COPD.

Frequently asked questions

What does the VA require for a secondary claim?

Three things: a current diagnosis of the secondary condition, an already service-connected primary disability such as obstructive sleep apnea, and a medical nexus opinion stating the secondary condition is at least as likely as not caused or aggravated by that primary disability.

Which conditions are most commonly claimed secondary to sleep apnea?

Hypertension, type 2 diabetes, GERD, depression and anxiety, migraines, coronary artery disease, atrial fibrillation, erectile dysfunction and stroke residuals are the most frequently claimed secondaries, because each has documented physiologic links to chronic intermittent hypoxia and fragmented sleep.

Can I claim a condition that sleep apnea only made worse?

Yes. Aggravation is a valid theory of secondary service connection. The letter must establish the baseline severity of the condition before the sleep apnea worsened it, and describe the additional disability attributable to the apnea.

Will filing secondary claims put my sleep apnea rating at risk?

Filing a new secondary claim does not by itself reopen your existing rating. Ratings that have been in place for long periods carry additional protections, and secondary conditions are rated separately and then combined.

Do I need a separate nexus letter for each secondary condition?

Not always. A single letter can address multiple secondary conditions when the records support each one. The free consultation is used to decide which conditions have strong enough medical support to include.

Not sure which secondaries to file?

A free phone consultation covers your diagnosis list, your records and which secondary conditions have the strongest medical support.
