Commonly Overlooked VA Disability Conditions

Many veterans file for a handful of obvious conditions and stop there. But the VA rating schedule under 38 CFR Part 4 covers hundreds of ratable conditions, and secondary service connection under 38 CFR 3.310 means one service-connected condition can lead to several more.

Common reasons veterans miss conditions:

• "It's not bad enough" — Veterans trained to push through pain minimize symptoms that are ratable
• Only filing the obvious — Claiming a back injury but not the radiculopathy, depression, or GERD it causes
• Not knowing about secondary claims — A condition caused or aggravated by a service-connected disability is also service-connected (38 CFR 3.310)
• Not knowing about presumptive conditions — Some conditions require no nexus letter, only qualifying service and a current diagnosis
• Dismissing 0% ratings — A 0% rating costs nothing to file but establishes service connection for future claims
• Stigma — Mental health conditions and erectile dysfunction are especially under-claimed

Most veterans associate VA mental health claims with PTSD (DC 9411), but all mental disorders under 38 CFR 4.130 are rated under the same General Rating Formula for Mental Disorders (0%, 10%, 30%, 50%, 70%, 100%), regardless of diagnosis.

Diagnostic Codes

Why These Are Overlooked

• Veterans believe only PTSD qualifies for mental health claims
• Symptoms of depression and anxiety overlap with PTSD but may be diagnosed differently
• Mental health stigma — many veterans never seek treatment, let alone file a claim
• "Not bad enough" mentality leads veterans to minimize real symptoms

Service Connection Paths

• Direct: In-service event + current diagnosis + medical nexus. Unlike PTSD, anxiety and depression do not require a specific verified stressor.
• Secondary (38 CFR 3.310): Depression or anxiety caused or aggravated by a service-connected physical condition (chronic pain, tinnitus, limited mobility). This is one of the most common secondary claims.
• Presumptive secondary to TBI (38 CFR 3.310(d)): Depression is presumptively secondary to service-connected TBI — within 3 years of moderate/severe TBI, or within 12 months of mild TBI.

38 CFR 4.130 (mental disorders), 38 CFR 4.97 DC 6847 (sleep apnea), 38 CFR 4.124a DC 8045 (TBI), 38 CFR 3.310(d) (TBI presumptives)

Musculoskeletal conditions are among the most commonly claimed, but many specific conditions remain overlooked — especially foot conditions, conditions that develop over time, and conditions on the "other side" of the body from an existing injury.

Foot Conditions

DC 5276 (Pes Planus) ratings: 0% — mild, relieved by arch support; 10% — moderate (bilateral or unilateral), weight-bearing line over great toe, pain on manipulation; 20% unilateral / 30% bilateral — severe, marked deformity, characteristic callosities; 30% unilateral / 50% bilateral — pronounced, marked pronation, extreme tenderness, not improved by orthopedic shoes.

Important (38 CFR 4.57): VA distinguishes between congenital and acquired flatfoot. Congenital flatfoot without abnormal callosities, pressure, strain, or tenderness is not compensable. However, congenital flatfoot aggravated by service (rucking, running, prolonged standing) may be service-connected under aggravation theory.

• Why overlooked: Veterans accept foot pain as normal. Plantar fasciitis has no dedicated DC (rated by analogy under DC 5284). Veterans with flat feet noted at MEPS may not realize they can claim aggravation.
• Service connection: Direct (documented foot complaints, physically demanding MOS), aggravation (pre-existing worsened by service), or secondary (plantar fasciitis from altered gait due to knee/back conditions).

Knees

• Key fact: VA can rate multiple aspects of a knee separately — instability AND limitation of motion can be rated independently under separate DCs (VAOPGCPREC 23-97, VAOPGCPREC 9-98).
• Commonly missed: The "opposite knee" secondary claim — limping from one service-connected knee shifts weight to the other, causing a compensable condition.
• Secondary chain: Knee → opposite knee (altered gait) → hip conditions → back conditions → radiculopathy.

Back (Lumbar Spine)

• Why overlooked: While back pain is commonly claimed, many veterans do not claim associated neurological conditions (radiculopathy) separately. IVDS with incapacitating episodes has its own rating formula that can yield a higher rating.
• Key secondary claims from back: Radiculopathy in lower extremities (DC 8520 — sciatic nerve), bladder dysfunction, bowel dysfunction, erectile dysfunction.

Neck (Cervical Spine) and Shoulders

• Why overlooked: Veterans focus on back pain but neglect neck conditions from heavy gear, body armor, helmets, and parachute landings. Cervical radiculopathy (upper extremities) is frequently missed as a secondary claim. Shoulder injuries from repetitive overhead lifting and weapon use are attributed to "getting older."

Shin Splints

Medial tibial stress syndrome is rated by analogy under DC 5262 (tibia/fibula impairment) or DC 5299-5262. Considered a "training injury" that should resolve, but for many veterans it becomes chronic. No specific diagnostic code exists, and veterans may not have sought treatment in service because it was seen as minor.

38 CFR 4.71a (musculoskeletal), 38 CFR 4.57 (flatfoot), VAOPGCPREC 23-97 and 9-98 (separate knee ratings)

Tinnitus

DC 6260 (38 CFR 4.87) — Maximum schedular rating is 10%, assigned as a single rating regardless of whether perceived in one ear, both ears, or in the head.

Why still overlooked: Despite being the #1 most commonly claimed VA disability, many veterans do not file because they consider ringing in the ears "normal" or minor. A 10% tinnitus rating provides VA healthcare access and serves as a basis for secondary claims (depression/anxiety secondary to tinnitus). No audiometric test can definitively prove or disprove tinnitus — lay testimony is particularly important.

Presumptive: Tinnitus (as an organic disease of the nervous system) is presumptive if it manifests to 10% within 1 year of separation under 38 CFR 3.309(a).

Hearing Loss

DC 6100 (38 CFR 4.85, 4.86) — Mild hearing loss often results in a 0% rating, leading veterans to think "why bother." But a 0% service-connected rating establishes the link for future claims if hearing worsens. Hearing loss is progressive — a veteran who tests at 0% at separation may qualify for a compensable rating years later.

Presumptive: Sensorineural hearing loss is presumptive if it manifests to 10% within 1 year of separation under 38 CFR 3.309(a).

Sinusitis and Rhinitis

DC 6522 (Rhinitis) ratings: 10% — without polyps, but with greater than 50% obstruction of nasal passage on both sides or complete obstruction on one side; 30% — with polyps.

DC 6502 (Deviated Septum): 10% with 50% obstruction of both sides or complete obstruction on one side. Can serve as the basis for secondary sinusitis and rhinitis claims.

Why overlooked: Veterans exposed to burn pits, dust, sand, and other environmental hazards frequently develop chronic sinusitis and rhinitis but do not connect it to service. These conditions are presumptive for certain toxic exposure veterans under the PACT Act. Rhinitis/sinusitis secondary to deviated septum is commonly missed.

38 CFR 4.87 DC 6260 (tinnitus), 38 CFR 4.85-4.86 DC 6100 (hearing loss), 38 CFR 4.97 DC 6502-6522 (ENT), 38 CFR 3.309(a) (chronic disease presumptives)

Dermatitis / Eczema Rating Criteria (DC 7806)

0% — less than 5% of body/exposed areas, topical therapy only; 10% — 5% to less than 20%, or intermittent systemic therapy (corticosteroids/immunosuppressives) for less than 6 weeks in past 12 months; 30% — 20–40% or systemic therapy 6+ weeks but not constant; 60% — more than 40% or constant/near-constant systemic therapy.

Why Skin Conditions Are Overlooked

• Veterans consider skin conditions "cosmetic" or minor, but they can rate up to 60%
• Eczema and dermatitis from deployment (environmental exposure, chemicals, stress) may need a nexus opinion
• Surgical scars from in-service procedures are often not claimed — even a single painful or unstable scar is rated 10% under DC 7804
• Skin cancer from sun exposure during outdoor service is not commonly claimed despite being service-connectable

Scars — Commonly Missed

DC 7804: One or two unstable or painful scars = 10%; three or four = 20%; five or more = 30%. DC 7805: Scars may also be rated based on limitation of function of the affected part. Scars from in-service surgeries (knee, appendectomy, etc.) and training injuries are frequently unclaimed.

38 CFR 4.118 DC 7800-7829 (skin), 38 CFR 3.309(e) (herbicide presumptives)

GERD / Acid Reflux

DC 7346 (Hiatal Hernia) ratings: 10% — two or more symptoms of the 30% criteria at lesser severity; 30% — persistently recurrent epigastric distress with dysphagia, pyrosis, and regurgitation, accompanied by substernal or arm/shoulder pain, productive of considerable impairment of health; 60% — symptoms of pain, vomiting, material weight loss and hematemesis or melena with moderate anemia, or other symptom combinations productive of severe impairment of health.

• Why overlooked: GERD is one of the most common secondary conditions but veterans frequently fail to claim it. Many take antacids daily without realizing they have a ratable condition.
• Common secondary paths: GERD secondary to NSAIDs prescribed for service-connected pain conditions (back, knees, shoulders) — the medication pathway is well-established. GERD secondary to stress/anxiety from service-connected PTSD.

Irritable Bowel Syndrome (IBS)

DC 7319 ratings: 0% — mild, occasional episodes of abdominal distress; 10% — moderate, frequent episodes; 30% — severe, diarrhea or alternating diarrhea and constipation with more or less constant abdominal distress (maximum rating).

38 CFR 4.114 DC 7206 (GERD), DC 7346 (hiatal hernia), DC 7319 (IBS); 38 CFR 3.317 (Gulf War presumptives)

Hypertension

DC 7101 (38 CFR 4.104) — Ratings: 10% — diastolic pressure predominantly 100 or more, or systolic pressure predominantly 160 or more, or minimum evaluation for individual with history of diastolic 100+ who requires continuous medication; 20% — diastolic 110+ or systolic 200+; 40% — diastolic 120+; 60% — diastolic 130+.

• Why overlooked: Many veterans take blood pressure medication prescribed by VA but never file a claim.
• Agent Orange presumptive: Hypertension was added as a presumptive condition for herbicide-exposed veterans under the PACT Act (38 CFR 3.309(e)).
• Common secondary connections: Hypertension secondary to PTSD (chronic stress), secondary to kidney conditions, secondary to sleep apnea, secondary to obesity caused by service-connected mobility limitations.

Ischemic Heart Disease

DC 7005 (38 CFR 4.104) — Ischemic heart disease (includes coronary artery disease, angina, heart attack, and other forms) is a presumptive condition for herbicide-exposed veterans under 38 CFR 3.309(e). Does NOT include hypertension or peripheral arterial disease.

Why overlooked: Veterans may develop heart disease decades after service and not connect it to herbicide exposure. Some veterans are unaware of their qualifying service — Thailand military bases, Korea DMZ, Guam, and test/storage locations also qualify, not just Vietnam.

38 CFR 4.104 DC 7005, DC 7101; 38 CFR 3.309(e) (herbicide presumptives)

Erectile Dysfunction

DC 7522 (38 CFR 4.115b) — Deformity of the penis with loss of erectile power = 20%. If only loss of erectile power is present (without deformity), the rating is typically 0% — but the veteran qualifies for Special Monthly Compensation at the K rate (SMC-K).

• Why overlooked: Stigma — many veterans are embarrassed to claim ED. Many do not know about SMC-K, which provides additional compensation even with a 0% ED rating.
• Common secondary connections: ED secondary to PTSD/depression (both the conditions and SSRIs), ED secondary to diabetes (Agent Orange presumptive diabetes frequently causes ED), ED secondary to spinal conditions/radiculopathy, ED secondary to hypertension medications, ED secondary to prostate conditions.

Kidney Conditions

Renal dysfunction is rated under 38 CFR 4.115a. Kidney conditions secondary to long-term NSAID use for service-connected pain are frequently missed. Also commonly secondary to hypertension and diabetes (especially Agent Orange presumptive Type 2 diabetes).

38 CFR 4.115b DC 7522 (ED), 38 USC 1114(k) / 38 CFR 3.350 (SMC-K), 38 CFR 4.115a (renal dysfunction)

Secondary service connection under 38 CFR 3.310 is where veterans leave the most rating points on the table. Two paths exist: (a) the service-connected condition caused the new condition, or (b) the service-connected condition aggravated a pre-existing non-service-connected condition.

Radiculopathy Secondary to Back or Neck

DC 8520 (Sciatic Nerve) ratings: 10% — mild incomplete paralysis; 20% — moderate; 40% — moderately severe; 60% — severe with marked muscular atrophy; 80% — complete paralysis. When nerve impairment is wholly sensory, the rating should be mild or at most moderate.

• Key fact: Each extremity affected is rated SEPARATELY — bilateral radiculopathy from a lumbar spine condition can receive separate ratings for left and right lower extremity
• Cervical radiculopathy (upper extremities) from neck conditions is frequently missed entirely

Migraines Secondary to TBI or Neck Conditions

DC 8100 (38 CFR 4.124a) — Ratings: 0% — less frequent attacks; 10% — characteristic prostrating attacks averaging one in 2 months; 30% — prostrating attacks once a month; 50% — very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability (maximum).

"Prostrating" means attacks producing powerlessness or lack of vitality. The 50% "severe economic inadaptability" does NOT require complete inability to work.

• Why overlooked: Veterans describe "headaches" but do not seek a formal migraine diagnosis
• Migraines secondary to TBI are extremely common but under-claimed
• Migraines secondary to cervical spine conditions (neck tension progressing to migraines)
• Migraines secondary to PTSD (stress and sleep disruption triggers)

Peripheral Neuropathy

Rated under various peripheral nerve codes (DC 8510–8730, 38 CFR 4.124a). Common secondary connections: peripheral neuropathy secondary to diabetes (especially Agent Orange presumptive Type 2 diabetes), secondary to toxic exposure (burn pits, chemicals). Early-onset peripheral neuropathy is a presumptive condition for herbicide-exposed veterans under 38 CFR 3.309(e) — must manifest to 10% within 1 year of last herbicide exposure.

Depression/Anxiety Secondary to Chronic Pain

Any service-connected condition causing chronic pain can support a secondary depression or anxiety claim under 38 CFR 3.310. No specific pain threshold is required — the nexus letter should explain how chronic pain limits activities and causes or worsens mood disorders. This can significantly increase the overall combined rating.

Sleep Apnea Secondary to PTSD or Weight Gain

Research supports a link between PTSD and sleep apnea. Weight gain from limited mobility due to service-connected orthopedic conditions is another pathway. Increasingly scrutinized by VA — a strong medical nexus letter is essential.

GERD Secondary to NSAID Use

NSAIDs prescribed for service-connected pain conditions are a well-established cause of GERD. The medication nexus is straightforward: document the prescriptions in VA or private medical records. Also claimable secondary to stress/anxiety from PTSD.

38 CFR 3.310 (secondary SC), 38 CFR 4.124a DC 8520 (sciatic nerve), DC 8100 (migraines), DC 8510-8730 (peripheral nerves)

Presumptive Conditions Veterans Miss

Certain conditions require no proof of service connection — only proof of qualifying service and a current diagnosis.

Chronic Diseases (38 CFR 3.309(a))

If a chronic disease manifests to 10% within 1 year of separation, it is presumptively service-connected. This includes arthritis, cardiovascular-renal disease (including hypertension), and organic diseases of the nervous system (including sensorineural hearing loss and tinnitus), among others listed in 38 CFR 3.309(a).

38 CFR 3.309(a) (chronic diseases), 38 CFR 3.309(e) (herbicide), 38 CFR 3.317 (Gulf War), 38 USC 1114(k) / 38 CFR 3.350 (SMC-K)
