Hallux valgus is a deformity of the first metatarsophalangeal (MTP) joint in which the great toe deviates laterally toward the second toe, while the first metatarsal head deviates medially, creating the visible bony prominence at the inner border of the foot known as a bunion. The condition is progressive — early hallux valgus may cause only cosmetic changes, while advanced deformity causes significant pain, difficulty wearing footwear, and functional limitation.
Hallux valgus is caused by a combination of genetic predisposition and external mechanical forces — particularly compressive footwear that forces the forefoot into a narrow toe box. Military footwear is among the most consistently identified aggravating factors in peer-reviewed orthopedic literature because:
The condition can be classified by severity using the Manchester scale (none, mild, moderate, severe) or by hallux valgus angle on X-ray (normal <15°; mild: 15–20°; moderate: 20–40°; severe: >40°). VA rating under DC 5280 does not require a specific angle measurement — the presence of the deformity, with or without symptoms, is sufficient for a compensable rating.
VA rates hallux valgus under Diagnostic Code 5280 in 38 CFR Part 4. The structure of DC 5280 is straightforward compared to many musculoskeletal codes — it is based on presence and laterality, not on specific ROM measurements:
| Condition | Rating |
|---|---|
| Unilateral hallux valgus — with or without symptoms | 10% |
| Bilateral hallux valgus — with or without symptoms | 20% |
The phrase "with or without symptoms" is important: VA does not require you to prove pain or functional limitation to receive the DC 5280 rating. The structural deformity alone qualifies. However, if your bunion does cause pain or functional limitation, documenting those symptoms strengthens your claim and may support additional ratings under related DC codes.
While DC 5280 doesn't require proof of symptoms for the base rating, documenting your symptoms matters for two reasons: (1) it establishes a record for future rating increases if the condition worsens, and (2) painful motion under 38 CFR 4.59 or functional loss under 38 CFR 4.40 may support additional ratings for secondary effects like great toe stiffness, altered gait, or secondary plantar fasciitis.
Hallux valgus frequently co-occurs with other ratable foot conditions. The following DC codes may be relevant to a complete foot claim:
| DC | Condition | Connection to Bunion |
|---|---|---|
| 5280 | Hallux valgus | Primary bunion code |
| 5158 | Hallux rigidus (great toe limited motion) | Advanced bunion with MTP joint stiffness |
| 5276 | Flatfoot, acquired | Co-occurring or secondary to gait changes |
| 5284 | Foot injuries, other | Functional foot impairment not captured by specific codes |
| 7804 | Scar, unstable or painful | Post-surgical scar from bunionectomy |
| 7805 | Scar, other (area-based) | Post-surgical scar not qualifying for 7804 |
For veterans with both hallux valgus and acquired flatfoot, both conditions can be service-connected and rated separately. See our guides on flat feet and plantar fasciitis for additional DC codes and rating criteria that may apply to your foot claim.
Military service provides multiple documented pathways to hallux valgus development or aggravation. For service connection, you need to show that your bunion either began during service or was materially worsened beyond its natural progression by service activities.
Army Combat Boots, Marine Corps boots, and service branch dress shoes have historically featured narrow toe boxes that force the great toe into lateral deviation under load. The Army's own studies have documented higher-than-expected rates of hallux valgus in soldiers, particularly female soldiers wearing Army dress pumps. A nexus letter citing the standard footwear requirements for the veteran's era and MOS strengthens service connection.
The compressive forces on the forefoot increase dramatically with rucksack load. Studies of military foot pathology show that 12-mile ruck marches with 35-pound loads increase forefoot compressive forces by 1.5–2x compared to normal walking. Sustained repetition of this loading pattern over years of service creates the precise mechanical conditions for hallux valgus progression.
Female veterans are disproportionately affected by hallux valgus from military service due to the mandatory wear of narrow-toed dress shoes and pumps. If you are a female veteran with bunions, the service connection argument is strong — document the specific military dress shoe requirements during your service years and any in-service foot complaints. VA has acknowledged the foot pathology link to female military footwear requirements in multiple Board decisions.
DC 5280 has a built-in bilateral structure: the 20% rating applies to bilateral hallux valgus as a single rating entry. This is slightly different from how other conditions use the bilateral factor under 38 CFR § 4.68.
If you have both bilateral hallux valgus (20% under DC 5280) and other bilateral lower extremity conditions (such as bilateral flat feet under DC 5276, bilateral plantar fasciitis, or bilateral shin splints under DC 5262 by analogy), the bilateral factor applies to those additional bilateral pairs, further increasing your combined rating.
Example combined foot claim:
| Condition | Rating |
|---|---|
| Bilateral hallux valgus (DC 5280) | 20% |
| Bilateral acquired flatfoot right (DC 5276) | 10% |
| Bilateral acquired flatfoot left (DC 5276) | 10% |
| Bilateral factor on flat feet | +~2% |
| Combined (VA math) | ~37% |
See our detailed guide on the VA bilateral factor for how these calculations work in your combined rating calculation.
Many veterans with hallux valgus have undergone surgical correction — bunionectomy, Chevron osteotomy, Lapidus procedure, or Austin procedure. Post-surgical VA rating focuses on residual functional limitations after recovery, not the pre-surgical deformity alone.
If your bunion was service-connected at 10% or 20% and you had surgery after discharge, the post-surgical residuals are also ratable — the surgery was on the service-connected condition. VA must rate you based on your current level of disability, which includes any surgical residuals from treating the service-connected bunion.
"Based on my review of [veteran's] service treatment records, VA examination records, X-rays of bilateral feet showing hallux valgus angles of 25° right and 22° left, and her DD-214 reflecting 12 years of active duty service in administrative roles requiring daily wear of Army Service Uniform dress shoes, it is my medical opinion that it is at least as likely as not (50% or greater probability) that her bilateral hallux valgus is directly caused and materially worsened by her military service. The narrow toe-box design of military dress footwear, combined with daily wear during prolonged standing and walking on hard floor surfaces across 12 years of service, constitutes the compressive mechanical loading pattern established in the orthopedic literature as the primary extrinsic cause of hallux valgus progression. Her current bilateral deformity is consistent with this mechanism of injury and warrants rating under DC 5280 for bilateral hallux valgus."
Hallux valgus alters forefoot biomechanics and can cause or contribute to several secondary conditions, each separately ratable if causally linked to the service-connected bunion:
Complete Foot Claim Strategy
Bilateral bunions combined with flat feet, plantar fasciitis, and post-surgical residuals can result in a combined foot rating well above 20%. REE Medical's specialists can provide a comprehensive nexus addressing each foot condition and their inter-relationships in a single evaluation package.
