The Department of Veterans Affairs (VA) rates ankle conditions between 10 percent and 40 percent under Title 38 of the Code of Federal Regulations (CFR) Section 4.71a. At Rank and Pay, we examine disability schedules to show veterans how their medical records map to rating criteria.

Ratings depend on measured range of motion, joint ankylosis, bone malunion, or surgical bone excision. Most ankle disability claims involve sprains, chronic instability, or arthritis, which the VA evaluates under Diagnostic Code (DC) 5271 based on limited motion or painful movement.

When an ankle injury restricts joint movement or impairs your walking mechanics, disability benefits provide monthly tax-free payments under the VA disability compensation program. If both lower extremities are affected, the VA applies a bilateral factor that increases your combined disability percentage.

The Five VA Diagnostic Codes for Ankle Conditions

The VA evaluates all ankle disabilities under five specific diagnostic codes in the musculoskeletal rating schedule under 38 CFR Part 4.

Diagnostic codes 5270 through 5274 address different structural and functional impairments of the ankle and tarsal joints. Each code assigns a percentage based on physical degrees of motion loss, the quality of the weight-bearing alignment, or surgical removal of bone.

Ankylosis means the joint is completely fused or fixed in place, eliminating motion entirely. Because ankylosis represents the most severe functional restriction short of amputation, Diagnostic Code 5270 provides the highest standalone ankle rating on the schedule at 40 percent.

Limited Motion and the Painful-Motion Rule

Diagnostic Code 5271 serves as the primary rating code for common ankle conditions such as chronic sprains, recurrent joint instability, and post-traumatic arthritis.

Normal ankle movement consists of dorsiflexion, which pulls the foot up toward the shin, and plantar flexion, which points the foot downward toward the floor. To receive a 20 percent rating under Diagnostic Code 5271, your dorsiflexion must be restricted to less than 5 degrees, or your plantar flexion must stop at less than 10 degrees. Moderate limitation yields a 10 percent rating when dorsiflexion remains below 15 degrees or plantar flexion stays below 30 degrees.

Many veterans retain functional degrees of movement but experience sharp pain whenever they flex or rotate their ankle. Under 38 CFR Section 4.59, known as the painful-motion rule, pain that limits motion must be compensated even if your measured range of motion exceeds the numeric thresholds in the rating schedule. If a physical examination shows that movement causes pain, the VA must award at least the minimum compensable rating of 10 percent for the affected joint.

Applying the Bilateral Factor to Ankle Claims

The VA applies a bilateral factor under 38 CFR Section 4.26 whenever a veteran has service-connected disabilities affecting paired skeletal extremities.

When you have disability ratings for both lower extremities, the VA combines those ratings first, adds 10 percent of that combined value, and then combines the resulting figure with your other service-connected conditions. For instance, if you have a service-connected left ankle rating and a service-connected right ankle rating, or a left ankle rating paired with a right knee or hip disability, the bilateral factor increases your combined total.

This calculation raises your combined percentage because injuries on both sides of the lower body compound the strain on your gait and balance. You can calculate your combined rating with our VA disability rating calculator to see how bilateral lower extremity ratings adjust your final percentage.

Direct and Secondary Service Connection for Ankle Injuries

Veterans can establish service connection for an ankle condition through either a direct in-service injury or a secondary disability caused by another service-connected condition.

Direct service connection requires three distinct evidentiary elements: an in-service injury or event, such as a parachute landing fall, field exercise sprain, or vehicle incident; a current medical diagnosis of an ankle disability; and a medical nexus linking the current diagnosis to the military incident. A formal medical nexus letter from a qualified physician can supply the necessary medical rationale showing your condition is at least as likely as not related to your service.

Secondary service connection occurs when an existing service-connected disability causes or aggravates your ankle problem. Common secondary claims involve an altered walking gait caused by a service-connected knee, hip, or lumbar spine condition, which shifts body weight unevenly and overstresses the ankle joint. Similarly, an existing service-connected injury in one ankle often forces the opposite ankle to bear excess weight, causing secondary instability or accelerated arthritis.

Compensation and Pension Exam Procedures for Ankle Claims

A Compensation and Pension (C&P) exam for an ankle claim measures range of motion, tests joint stability, and documents the presence of pain during movement.

During the examination, the medical examiner must use a handheld tool called a goniometer to measure your active and passive range of motion in degrees. The examiner records when pain begins during flexion, whether motion causes weakness or fatigue, and how repeated movement degrades joint function over time. The examiner must also assess whether your condition causes flare-ups that temporarily reduce your functional movement further.

For claims involving surgical history or joint fusion, the examiner determines whether bones such as the os calcis or astragalus healed in malunion, and checks whether the joint remains in a favorable or poor weight-bearing position. Because raters rely directly on the examiner's disability benefits questionnaire, ensuring that your medical file contains records of flare-ups and functional limits during daily work helps establish an accurate rating.

Unemployability and Special Compensation Programs

Severe ankle disabilities that prevent steady employment or cause functional loss can qualify veterans for disability programs beyond the standard rating schedule.

Total Disability based on Individual Unemployability (TDIU) allows qualifying veterans to receive monthly payments at the 100 percent disability rate when service-connected disabilities prevent them from securing substantially gainful employment. While ankle conditions alone rarely reach the individual percentage thresholds for standard schedular TDIU, severe ankle instability or joint ankylosis combined with other service-connected conditions can establish TDIU eligibility if your physical mobility restrictions eliminate your ability to maintain work.

Special Monthly Compensation (SMC) provides additional tax-free financial compensation for specific severe disabilities that exceed standard ratings, such as the complete anatomical loss or loss of use of a foot. These programs do not serve veterans with mild, isolated ankle conditions that respond to routine treatment and do not impede ordinary desk work or daily walking. An ankle injury causing only occasional mild soreness, with no effect on your ability to work, does not meet the substantially-gainful-employment threshold TDIU requires.

Monthly Compensation Rates for Ankle Ratings

The VA pays monthly tax-free disability compensation according to the veteran's combined disability rating, with rates updated under the 2026 cost-of-living adjustment.

Effective December 1, 2025, the 2026 compensation schedule sets monthly payments for a veteran without dependents at $180.42 for a 10 percent rating, $356.66 for a 20 percent rating, $552.47 for a 30 percent rating, and $795.84 for a 40 percent rating. Because the highest standalone ankle rating under Diagnostic Code 5270 is 40 percent, an ankle rating by itself pays up to $795.84 per month unless combined with additional service-connected conditions.

Veterans with qualifying dependents, such as a spouse, children, or dependent parents, receive additional monthly compensation once their combined rating reaches 30 percent or higher. Our guidance on claim valuation would change if Congress adjusts statutory rating schedules or if the VA amends the musculoskeletal diagnostic criteria in 38 CFR Part 4 to alter range-of-motion cutoff angles.

To move forward with a claim, gather your service treatment records, obtain a current clinical diagnosis from your treating physician, and use our VA disability claim eligibility quiz to confirm your evidentiary requirements before submitting your application.
