Degenerative Arthritis
Degenerative arthritis (osteoarthritis) is the gradual breakdown of the cartilage that cushions a joint, producing pain, stiffness, swelling and reduced motion. DC 5003 is not primarily a ladder of its own: the schedule rates degenerative arthritis established by X-ray "on the basis of limitation of motion under the appropriate diagnostic codes for the specific joint or joints involved", so most evaluations come from the affected joint's own code and DC 5003 supplies a floor.
Degenerative Arthritis VA Rating Tiers
The VA rates Degenerative Arthritis the same way whether it's claimed directly or as secondary to Muscle Group XI - Calf and Posterior Leg Muscles (Plantar Flexion) — severity of Degenerative Arthritis itself determines the percentage.
Example combined rating
10% Muscle Group XI - Calf and Posterior Leg Muscles (Plantar Flexion) + 10% Degenerative Arthritis = 19%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 10% and 10% combine to 19%, not 20%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Degenerative Arthritis Secondary Claim

- •Documentation of any incapacitating episodes or flare-ups, since these are what can raise a claim from the 10% to the 20% tier.
