The Achilles tendon is the largest tendon in the body, connecting the gastrocnemius and soleus muscles of the calf to the calcaneus (heel bone). It is essential for walking, running, jumping, and climbing — all fundamental military activities. The tendon has limited blood supply, making it prone to degeneration under sustained load and slow to heal once injured.
In military populations, Achilles tendon injuries present in three primary patterns:
Each of these injury types can result in permanent residuals — limited range of motion, chronic pain, weakness, and functional limitations — that form the basis of a VA disability claim.
VA rates Achilles tendon conditions primarily under Diagnostic Code 5271 — "Ankle, limited motion of" — found in 38 CFR Part 4, Schedule for Rating Disabilities, under the musculoskeletal system. DC 5271 rates based on the degree of limitation in ankle dorsiflexion and plantar flexion.
Other DC codes that may apply to Achilles tendon conditions:
| DC | Condition | When Applied |
|---|---|---|
| 5271 | Limited motion of ankle | Primary code — most Achilles conditions |
| 5270 | Ankylosis of ankle | Complete loss of ankle motion post-injury/surgery |
| 5276 | Flatfoot, acquired | If Achilles tightness contributed to flatfoot development |
| 5284 | Foot injuries, other | If foot function (not just ankle ROM) is primarily affected |
| 7804 | Scar, unstable/painful | Post-surgical scar at surgical repair site |
VA must rate under whichever code most accurately describes the disability — or the code that produces the highest rating. If your Achilles repair left a painful surgical scar and limited ankle motion, you may be entitled to separate ratings for both. See also our guide on VA disability rating for ankle injuries for the complete picture of ankle DC codes.
Normal ankle range of motion is: dorsiflexion 0–20 degrees, plantar flexion 0–45 degrees. VA uses the following ROM findings to assign ratings under DC 5271:
| Degree of Limitation | ROM Finding | Rating |
|---|---|---|
| Moderate | Dorsiflexion limited to 10° or less; plantar flexion limited to 30° or less | 10% |
| Marked | Dorsiflexion limited to 0° (neutral position) or plantar flexion markedly restricted | 20% |
For complete ankylosis under DC 5270, ratings are higher and depend on the position of ankylosis:
| Ankylosis Position | Rating |
|---|---|
| Favorable (plantigrade — foot at 90° to leg) | 20% |
| Intermediate between favorable/unfavorable | 30% |
| Unfavorable (plantar flexion, poor gait mechanics) | 40% |
If your condition is severe enough, VA is required to consider whether you meet criteria for a higher DC code. Always request that your C&P examiner measure both dorsiflexion and plantar flexion, and document any painful motion within that range. Even a 10% bilateral Achilles rating, combined with the bilateral factor, contributes meaningfully to your overall combined rating.
One of the most powerful and underutilized rating provisions for Achilles tendon claims is the painful motion doctrine under 38 CFR § 4.59. This regulation states that any motion that is painful is functionally equivalent to limitation of motion and must be rated at no less than the minimum compensable rating for that joint.
For ankle DC 5271, this means: if your Achilles tendinitis causes pain when you dorsiflex or plantar flex your ankle — even within the normal range of motion — you are entitled to at least a 10% rating. Many veterans with Achilles tendinitis retain full ROM between flare-ups, leading examiners to document "full range of motion" and assign 0%. This is incorrect if motion is painful.
At your C&P exam, every time the examiner asks you to move your ankle:
Service connection for Achilles tendon conditions requires three elements: (1) a current diagnosis, (2) an in-service event or injury, and (3) a nexus connecting the two. For infantry, Marine, Ranger, Special Forces, and other high-demand MOS veterans, establishing the in-service event is usually straightforward — the challenge is documentation.
Research consistently shows Achilles tendon pathology disproportionately affecting:
Gather the following to support your service connection claim:
Many veterans have sparse STRs because they — or their unit leadership — were culturally discouraged from seeking medical care. "Rub some dirt on it" is not a medical diagnosis, but it is a reality in many units. A strong personal statement explaining why care was not sought during service, combined with a credible nexus letter explaining how the condition relates to service duties, can overcome the documentation gap.
Complete Achilles tendon rupture is a more serious injury than tendinitis, and VA ratings reflect the residual functional limitations after treatment. The rating pathways differ depending on treatment approach:
Ruptures treated with immobilization (cast or walking boot) without surgery often result in lengthening of the tendon with some loss of push-off strength. Residual limitations include reduced plantar flexion strength, limited dorsiflexion, and persistent pain. Rate under DC 5271 based on current ROM measurements.
Surgical repair (primary repair or augmentation) is the most common treatment for complete rupture. Post-surgical considerations for VA rating include:
Veterans who experience re-rupture — particularly common in tendon repairs that were stressed too early or in veterans with underlying tendinopathy — may have more significant residual limitations. Failed surgical repair with chronic rupture status can result in significant ankle instability, requiring rating under DC 5270 (ankylosis) or the highest applicable code for the residual functional status.
"Based on my review of [veteran's] service treatment records, VA examination records, current clinical evaluation including goniometric measurement, and his DD-214 reflecting 8 years as an 11B Infantryman, it is my medical opinion that it is at least as likely as not (50% or greater probability) that his bilateral Achilles tendinopathy is directly caused by his military service. Infantry service with regular rucksack loads of 60–80 pounds, high-mileage physical training including 2–5 mile morning runs 5 days per week, and deployment to Afghanistan with extended foot patrols on mountainous terrain constitutes a pattern of cumulative repetitive loading on the Achilles tendons consistent with the established pathophysiology of overuse tendinopathy. Current examination reveals limited dorsiflexion bilaterally with painful motion beginning at 8 degrees on the right and 6 degrees on the left, consistent with chronic tendinopathy secondary to the cumulative military service described."
If you have service-connected Achilles tendon conditions in both legs — extremely common in infantry veterans given the bilateral nature of marching, running, and rucking — the bilateral factor under 38 CFR § 4.68 applies.
The bilateral factor adds 10% to the combined value of bilateral lower extremity disabilities before combining with other disabilities in the final combined rating calculation. Here is how it works for a bilateral Achilles claim:
| Condition | Individual Rating |
|---|---|
| Right Achilles tendinopathy (DC 5271) | 10% |
| Left Achilles tendinopathy (DC 5271) | 10% |
| Combined before bilateral factor | 19% |
| After 10% bilateral factor addition | ~21% |
See our guide on the VA bilateral factor for a detailed explanation of how this affects your combined rating calculation. Also relevant: if Achilles tendon injury contributed to altered gait and secondary flat feet or plantar fasciitis, those may be separately ratable as secondary conditions.
Achilles tendon injuries frequently produce biomechanical compensations that cause secondary conditions — and VA rates each service-connected condition separately. Common secondary conditions to consider:
The C&P (Compensation and Pension) exam is the most critical moment in an Achilles tendon claim. The examiner's findings determine your rating. Preparation is essential:
Under Correia v. McDonald (2017), if your Achilles condition worsens during flare-ups beyond your baseline, VA must consider flare-up severity. Document worst-day ROM in your personal statement and nexus letter — not just the baseline you have on a regular day. If flare-ups are your worst functional limitation, this matters enormously to your rating.
A strong nexus letter for an Achilles tendon claim should address all of the following:
