Complete loss of function in both feet without anatomical loss.
Because there is only one rating level — 100% — the evidence needs to show that you have lost the use of both feet. Medical records documenting the nature and extent of the condition in both feet are central. Examination findings that describe your inability to use the feet effectively, such as notes on sensation, movement, strength, and weight-bearing capacity, directly support the criteria.
If you use crutches permanently, records or statements establishing the earliest date that permanent crutch use began are relevant to the special monthly compensation provision tied to this code. Statements from you or people who observe your daily life can help show the functional impact on walking and mobility. Treatment records, imaging, and any specialist evaluations that confirm the bilateral nature and severity of the condition all bear directly on whether loss of use of both feet is established.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
