Common Questions About Ankle ankylosis (fixed joint) VA Ratings
What is the VA rating range for Ankle ankylosis (fixed joint)?
The VA rates Ankle ankylosis (fixed joint) under Diagnostic Code 5270 at 20%, 30%, 40%. The minimum 20% rating requires: In plantar flexion, less than 30°.. The maximum 40% rating requires: In plantar flexion at more than 40°, or in dorsiflexion at more than 10° or with abduction, adduction, inversion or eversion deformity..
Which 38 CFR diagnostic code does the VA use for Ankle ankylosis (fixed joint)?
The VA rates Ankle ankylosis (fixed joint) under Diagnostic Code (DC) 5270, published in 38 CFR § 4.71a. The diagnostic code establishes the specific rating tiers and severity criteria the VA examiner applies.
What is the difference between a 20% and a 40% rating for Ankle ankylosis (fixed joint)?
A 20% rating requires: In plantar flexion, less than 30°.. A 40% rating requires: In plantar flexion at more than 40°, or in dorsiflexion at more than 10° or with abduction, adduction, inversion or eversion deformity.. The difference typically reflects the frequency, severity, or functional impact of the condition as documented in medical records and C&P examination findings.
Can Ankle ankylosis (fixed joint) qualify for TDIU?
Possibly. Ankle ankylosis (fixed joint) maxes at 40%, which doesn't meet the single-disability TDIU threshold of 60% alone. However, if combined with other service-connected disabilities totaling 70%+ (with one at 40%+), TDIU under 38 CFR § 4.16(a) may apply. Extraschedular TDIU under § 4.16(b) is also available if the condition alone prevents work regardless of rating.
What evidence supports a higher rating for Ankle ankylosis (fixed joint)?
The key evidence for Ankle ankylosis (fixed joint) is documentation of how the condition affects daily functioning. For musculoskeletal conditions, range of motion measurements (active, passive, weight-bearing, and non-weight-bearing per Correia v. McDonald) and flare-up documentation are critical. A nexus letter from a qualified medical professional linking the current severity to service is essential for contested claims.
Which conditions are commonly secondary to Ankle ankylosis (fixed joint)?
Ankle ankylosis (fixed joint) is associated with 1 documented secondary condition. Secondary conditions caused or aggravated by a service-connected disability are ratable under 38 CFR § 3.310. See the secondary conditions page for the full list with medical rationale and evidence strength ratings.
What happens at the C&P exam for Ankle ankylosis (fixed joint)?
The C&P examiner uses a Musculoskeletal System DBQ and evaluates your condition against the DC 5270 rating criteria. Expect range of motion testing in multiple positions. Under Correia v. McDonald, the examiner must test active, passive, weight-bearing, and non-weight-bearing range of motion. Report your worst flare-up symptoms. If you cannot attend during a flare, request the exam be rescheduled.
