Christopher Wall served in the Marine Corps from 1997 to 2001. In this Woobie interview he describes recent medical evaluations of sleep apnea, anxiety and depression, and stomach conditions, and the support from his wife that kept him going. His path and result are his own; results vary.
Doc Matthew J. Wilyonson, M.D., Woobie’s Chief Medical Officer and a former Navy Lieutenant Commander in the Medical Corps, hosts.
Chris came to Woobie feeling that earlier medical records did not show his symptoms or limits. He started a new round of evaluations to cover the full picture.
How did Chris cope with the process?
He found it overwhelming at first, especially while dealing with anxiety and depression. Two things helped: his wife’s support, and the Woobie medical team, who laid out an evaluation plan and the assessments he needed.
What conditions were evaluated?
Woobie’s team reviewed Chris’s service treatment records and current symptoms rather than one issue at a time. Doc calls this a holistic review, aimed at limits that earlier exams may have missed. The evaluations covered:
- Sleep apnea. Chris had not documented how serious his sleep problems were. A medical evaluation and sleep study confirmed obstructive sleep apnea, and Woobie provided a formal medical opinion.
- Mental health. Woobie provided a detailed assessment of how his anxiety and depression limit him.
- GERD and ulcers. A medical review documented severe GERD and ulcers.
“Don’t let your symptoms go undocumented. The process is rigorous, but having the right medical evidence is essential.”
— Christopher Wall
What does “permanent” mean in medical terms?
Doc explains that permanence rests on medical evidence that a disability is not expected to improve. For chronic conditions, he says good records help in four ways:
- Continuity of care. Every provider sees the full picture of service-connected conditions.
- Fewer re-evaluations. Evidence of permanence can reduce how often you are re-examined.
- Informed decisions. Detailed nexus letters and DBQs give decision makers medical evidence.
- Programs for dependents. Clear records can support a veteran’s or dependents’ access to certain programs.
What this means for your own claim
- A rating does not equal P&T. Permanent and Total means VA considers the condition permanent and the rating total. It is separate from the rating percentage. See what P&T status is and how TDIU differs from 100% P&T.
- A diagnosis is not enough alone. For a condition like sleep apnea, VA needs a current diagnosis and a link to service. A medical opinion can come from any licensed provider and uses the “at least as likely as not” standard.
- Your ratings combine. VA does not add percentages; use the free VA disability calculator to see how they combine.
- Help filing is free from an accredited VSO.
Chris’s outcome is his own. Woobie provides medical consulting and education, does not file claims and cannot promise any rating. Read Amos’s path from 80% to 100% P&T for another example.
Frequently asked questions
What is the difference between a 100% rating and P&T?
A 100% rating is the percentage VA assigns. Permanent and Total means VA considers the condition permanent and the rating total, so routine re-exams generally stop and some family benefits can follow. They can differ.
What does VA need to service connect sleep apnea?
VA looks for a current diagnosis, usually from a sleep study, and a link to service or to another service-connected condition. A medical opinion can explain that link. VA decides each claim on its evidence.
Does this story show a typical result?
No. Chris describes his own path. Ratings and timelines depend on each veteran’s conditions and evidence, and results vary.
