PTSD

Post-Traumatic Stress Disorder is commonly linked to many secondary physical and mental conditions.

8 known secondary conditions

Secondary Conditions

The following conditions may be claimed as secondary to PTSD:

Sleep Apnea

DC: 6847 Max Rating: 100%
Caused By Established Link

Medical Connection

Research demonstrates a strong bidirectional relationship between PTSD and sleep apnea. PTSD causes chronic sleep disruption, hyperarousal, and weight gain from medications - all risk factors for OSA.

Evidence Tips

  • Sleep study (polysomnography) confirming diagnosis
  • Medical opinion linking sleep apnea to PTSD
  • Documentation of sleep disturbance from PTSD records
  • Research studies showing PTSD-sleep apnea connection

Hypertension

DC: 7101 Max Rating: 60%
Caused By Strong Evidence

Medical Connection

PTSD causes chronic elevated stress hormones (cortisol, adrenaline), hyperarousal, and dysregulation of the autonomic nervous system, all of which contribute to elevated blood pressure.

Evidence Tips

  • Blood pressure readings over time
  • Medical opinion linking hypertension to PTSD
  • Documentation of medication use
  • Studies on PTSD and cardiovascular effects

Migraines/Headaches

DC: 8100 Max Rating: 50%
Caused By Established Link

Medical Connection

PTSD-related chronic stress, sleep deprivation, muscle tension, and hypervigilance are known triggers for chronic migraines and tension headaches.

Evidence Tips

  • Headache diary documenting frequency and severity
  • Medical records showing headache treatment
  • Nexus letter from neurologist or primary care
  • Documentation of headache onset timing relative to PTSD

Gastrointestinal Disorders (GERD, IBS)

DC: 7346/7319 Max Rating: 60%
Caused By Established Link

Medical Connection

Chronic stress from PTSD affects the gut-brain axis, increases stomach acid production, and causes gastrointestinal dysfunction.

Evidence Tips

  • Endoscopy or other diagnostic testing
  • Medication records for GI conditions
  • Medical opinion connecting GI issues to PTSD stress

Erectile Dysfunction

DC: 7522 Max Rating: SMC-K
Caused By Established Link

Medical Connection

PTSD medications (especially SSRIs) commonly cause ED as a side effect. Additionally, PTSD-related anxiety and depression can directly cause ED.

Evidence Tips

  • List of medications causing ED as side effect
  • Medical records documenting ED diagnosis
  • Note: ED qualifies for Special Monthly Compensation (SMC-K)

Weight Gain/Obesity

DC: N/A Max Rating: N/A (supports other claims)
Caused By Strong Evidence

Medical Connection

PTSD medications (antidepressants, antipsychotics) commonly cause significant weight gain. Additionally, PTSD-related depression affects motivation for exercise.

Evidence Tips

  • Weight records before and after PTSD treatment
  • Medication documentation with weight gain side effects
  • This can support secondary claims for sleep apnea, heart disease, diabetes

Substance Abuse Disorder

DC: 9431 Max Rating: 100%
Caused By Established Link

Medical Connection

Self-medication with alcohol or drugs to cope with PTSD symptoms is well-documented. The VA recognizes substance abuse secondary to mental health conditions.

Evidence Tips

  • Treatment records for substance abuse
  • Mental health records showing self-medication pattern
  • Therapist statements linking substance use to PTSD symptoms

Depression/Anxiety

DC: 9434/9400 Max Rating: Note: Only ONE mental health rating allowed
Caused By Established Link

Medical Connection

PTSD commonly co-occurs with or causes major depressive disorder and generalized anxiety disorder due to shared neurobiological pathways.

Evidence Tips

  • Mental health evaluations documenting both conditions
  • Note: Mental health conditions are rated together under the General Rating Formula

Tips for Filing Secondary Claims

  • Get a nexus letter: A medical opinion specifically stating your secondary condition is "at least as likely as not" caused by or aggravated by your primary condition is crucial.
  • Document the timeline: Show when your secondary condition developed relative to your primary condition. Earlier development strengthens the connection.
  • Include research: Medical studies showing the connection between conditions can support your claim. Your doctor can reference these in their nexus letter.
  • Be specific on VA Form 21-526EZ: When describing your condition, explicitly state it is "secondary to [your primary condition]" to ensure proper processing.
