Hallux Rigidus VA Disability Rating: Beyond the 10% Cap Under DC 5281

The VA rates hallux rigidus under Diagnostic Code 5281, which caps at 10 percent per foot. That ceiling is real, but it is not the end of the analysis. Veterans routinely build a combined hallux rigidus VA disability rating well above 10 percent by pursuing an analogous rating under a broader foot-injury code, applying the bilateral factor when both feet are involved, and claiming secondary service connection for the knee, hip, ankle, and back conditions that stiff-toe gait tends to produce over time.

What the 10 Percent Cap Under DC 5281 Actually Covers

Diagnostic Code 5281 tells the VA to rate hallux rigidus using the same criteria as severe hallux valgus under DC 5280.¹ A veteran earns the 10 percent one of two ways: the condition has been surgically treated with resection of the metatarsal head, or it is severe enough to be functionally equivalent to amputation of the great toe.² Anything less produces a noncompensable zero percent rating.

The Board of Veterans’ Appeals has repeatedly confirmed that DC 5281 does not provide for a higher schedular evaluation.³ The rating is also unilateral. If both feet are affected, each foot is evaluated on its own, so a veteran can hold 10 percent on the left and 10 percent on the right.

Getting Above 10 Percent: The DC 5284 Analogous Rating

The most direct route past the cap is an analogous rating under Diagnostic Code 5284, which covers “other foot injuries.” Under 38 C.F.R. § 4.20, the VA can rate a condition by analogy to a closely related diagnostic code when the listed code does not adequately capture the symptoms and functional impairment.² DC 5284 opens up a wider range:

10 percent for moderate foot injury residuals
20 percent for moderately severe residuals
30 percent for severe residuals
40 percent for actual loss of use of the foot¹

The Board has granted DC 5284 ratings for hallux rigidus in practice. In one 2009 decision, the BVA awarded 10 percent per foot under DC 5284 for bilateral hallux limitus involving hallux rigidus and arthritis, finding that limitation of motion and painful motion exceeded what DC 5281 could adequately capture.² In another case, the Board granted 20 percent ratings per foot, concluding that pain, limited standing and walking, and restricted range of motion equated to “moderately severe” foot disabilities.⁴

Reaching 30 percent for hallux rigidus alone is much harder. The Board has noted that a “severe” foot injury rating usually requires extensive symptomatology across the whole foot, such as marked deformity, multiple hammer toes, or extreme callosities, rather than impairment limited to the big toe.⁴

One legal caveat matters. In Scott v. Wilkie (2019), the Federal Circuit held that conditions specifically listed in the rating schedule generally cannot be rated under a different diagnostic code. At least one BVA decision has applied Scott to deny a hallux rigidus veteran a DC 5284 analogous rating on the reasoning that hallux rigidus already has its own code.³ Other Board decisions have gone the other way and allowed DC 5284. Outcomes vary by adjudicator, so veterans on this path benefit from strong medical evidence showing that hallux rigidus is affecting the entire foot, not only the big toe joint.

Bilateral Hallux Rigidus and the Bilateral Factor

When both feet are service-connected, the VA applies the bilateral factor under 38 C.F.R. § 4.26. It recognizes that paired-extremity disabilities are more disabling than the same ratings on a single side.⁵

The math: combine the two ratings using standard VA combined-ratings math, then add (not combine) 10 percent of that value. Two 10 percent ratings combine to 19 percent. Ten percent of 19 is 1.9, which is added to reach 20.9, rounded to 21 percent. That 21 percent then enters the overall combined rating with any other service-connected disabilities.⁵ A 2023 rule change added a safety valve: if applying the bilateral factor actually produces a lower evaluation, the VA excludes those disabilities from the bilateral calculation and combines them separately, choosing whichever result favors the veteran.⁶

Secondary Conditions From Altered Gait

For many veterans, the largest single boost to a combined rating comes from secondary claims, not from the toe itself. A stiff, painful big toe joint changes how you walk. That altered gait shifts stress up the kinetic chain and, over years, damages the ankles, knees, hips, and lower back.

The VA recognizes this mechanism. Under 38 C.F.R. § 3.310, a condition caused or permanently aggravated by an already service-connected disability can itself be service-connected.⁷ BVA decisions have granted secondary service connection tied to hallux rigidus for:

Ankle degenerative joint disease, permanently aggravated by hallux rigidus, based on a VA podiatrist’s opinion linking abnormal weight-bearing to ankle degeneration.⁷
Hip degenerative joint disease and strain, where loss of sagittal plane mobility in the big toe forced compensatory out-toeing into a hip-rotated position.⁸
Knee meniscal tears and degenerative changes, where compensatory gait placed excessive medial stress on the knee.⁸
Lumbar spine degenerative joint disease, secondary to bilateral foot and knee disabilities, where a chiropractor documented that foot pronation caused pelvic unleveling and chronic low back pain.⁹

A 2025 BVA decision laid the biomechanical chain out clearly: loss of sagittal plane mobility in the big toe leads to compensatory out-toeing, stress at the medial knee, and excessive lumbar shearing during the stance phase of walking. The Board granted secondary service connection for lower spine arthritis, a left knee meniscal tear, and a right hip strain, all linked back to a decades-old crush injury that produced hallux rigidus.⁸

Establishing these connections usually requires a medical nexus letter from a physician explaining how hallux rigidus caused or worsened the claimed condition. The legal standard is “at least as likely as not,” meaning a 50 percent or greater probability that the link exists.

Why You Cannot Add Arthritis On Top: Pyramiding

Hallux rigidus is itself a form of osteoarthritis, and X-rays commonly show degenerative joint disease at the first metatarsophalangeal joint. Some veterans try to add a separate rating for the arthritis under DC 5003 on top of DC 5281. The VA generally will not allow this.

Under 38 C.F.R. § 4.14, the anti-pyramiding rule bars rating the same disability, or the same symptoms, twice under different codes. The Board treats hallux rigidus as a manifestation of osteoarthritis, not a separate condition from it. In a 2021 decision, the BVA stated that “hallux rigidus is a presentation of the Veteran’s osteoarthritis” and that assigning separate ratings under both DC 5281 and DC 5284 “would be duplicative and violate the rule against pyramiding.”¹⁰ The same idea limits stacking with overlapping foot conditions like plantar fasciitis or pes planus: separate ratings are permitted only when the conditions produce “separate and distinct manifestations” under Esteban v. Brown.¹¹

Establishing Service Connection First

Before any rating applies, the veteran must first establish that hallux rigidus is connected to service. There are three pathways.

Direct service connection requires a current diagnosis of hallux rigidus, evidence of an in-service event or injury (fractures, repetitive stress from marching or airborne operations, problems from improperly fitting boots), and a medical nexus linking the two.¹² A temporal relationship between onset and active duty can sometimes be enough to carry the causal link.

Secondary service connection applies when hallux rigidus itself develops because of another service-connected condition, such as a knee injury that shifted weight-bearing over years.⁷

Aggravation applies if hallux rigidus existed before service but worsened beyond its natural progression during duty. Medical documentation or expert testimony supports this route.

Evidence That Moves a Claim

X-rays are essential. They confirm the diagnosis and show the degree of joint degeneration. Clinical records should document dorsiflexion measurements at the MTP joint, functional loss from pain, and treatment history. Records showing that orthotics, injections, and physical therapy provided little relief help establish that the condition exceeds a “mild” threshold.¹³ Lay statements about pain frequency, gait changes, and effects on work and daily life count as probative evidence when consistent with the rest of the record.

The C&P Exam

The VA typically orders a Compensation and Pension exam. The examiner observes gait, tests range of motion at the MTP joint, checks for swelling or deformity, and manipulates the joint to assess pain. Functional loss is evaluated under the DeLuca factors: pain on use, weakness, fatigability, disturbance of locomotion, and impact on standing and walking endurance.⁴ Under Sharp v. Shulkin, the examiner should also evaluate symptoms during flare-ups when feasible.

Imaging may be ordered if recent X-rays are not on file. Veterans can request a copy of the exam report and can obtain a private medical opinion to challenge the findings if they disagree with the examiner’s conclusions.

Surgery and Temporary 100 Percent Ratings

Common procedures for hallux rigidus include cheilectomy (removal of bone spurs), debridement, and arthrodesis (fusion of the MTP joint). Under 38 C.F.R. § 4.30, any surgery for a service-connected disability requiring at least one month of convalescence qualifies for a temporary total 100 percent rating. The rating runs one, two, or three months after discharge, with extensions available for another one to three months when recovery is prolonged. Further extensions up to six months beyond the initial period can be approved by the Veterans Service Center Manager for severe post-operative residuals such as therapeutic immobilization of a major joint, the need for crutches with restricted weight-bearing, or house confinement.¹⁴

Once convalescence ends, the VA assigns the schedular rating. Resection of the metatarsal head alone satisfies the 10 percent criteria under DC 5281.

TDIU When Foot Pain Prevents Work

Veterans who cannot maintain substantially gainful employment because of service-connected disabilities may qualify for Total Disability based on Individual Unemployability, which pays at the 100 percent rate without a 100 percent combined rating. The schedular threshold is either one disability at 60 percent or higher, or a combined rating of 70 percent or more with at least one condition at 40 percent or higher.¹⁵ Veterans who fall short can still qualify under the extraschedular TDIU pathway if their conditions uniquely prevent employment.

Hallux rigidus alone at 10 percent will not meet those thresholds. Combined with secondary knee, hip, ankle, and back disabilities linked through altered gait, a combined rating can reach 70 percent. Under 38 C.F.R. § 4.16(a), disabilities resulting from a common medical root may be treated as a single disability for threshold purposes. For veterans in physically demanding jobs, evidence of reduced productivity, absenteeism during flare-ups, and inability to stand or walk for extended periods strengthens a TDIU claim.

Appealing a Low or Denied Rating

Common reasons the VA underrates hallux rigidus claims include using the wrong diagnostic code, running an inadequate C&P exam that misses functional limitations, and failing to rate secondary conditions. Under the Appeals Modernization Act of 2017, veterans have three options within one year of an unfavorable decision:

A supplemental claim, which lets you submit new and relevant evidence such as a private nexus letter, updated imaging, or lay statements about functional limitations.
A higher-level review, in which a senior VA employee re-examines the existing evidence for legal or procedural errors. No new evidence is allowed. This is useful when the original decision misapplied a diagnostic code or ignored evidence already in the file.
A Board appeal, in which a Veterans Law Judge reviews the case, with options for direct review, evidence submission, or a hearing. This track typically takes one to three years.¹⁶

You can switch between these pathways if one produces an unfavorable result. Federal law caps attorney fees at one-third of retroactive payments, collected on a contingency basis from past-due benefits.
