Degenerative Arthritis Secondary to Ankylosis of Thumb
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Degenerative Arthritis when it develops after Ankylosis of Thumb.
Why Degenerative Arthritis Is Linked to Ankylosis of Thumb

Primary condition · VASRD 5224
Ankylosis of Thumb
The thumb is fixed in one position and no longer moves. DC 5224 pays 20 percent when the fixed position is unfavorable and 10 percent when it is favorable, and unlike most upper-extremity codes it pays the same whether the thumb is on the dominant or the non-dominant hand.

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 Ankylosis of Thumb — severity of Degenerative Arthritis itself determines the percentage.
Example combined rating
20% Ankylosis of Thumb + 10% Degenerative Arthritis = 28%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 20% and 10% combine to 28%, not 30%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Degenerative Arthritis Secondary Claim
- •X-rays or an MRI confirming joint degeneration in each affected joint - this is the evidence the rating schedule is built around.
- •A doctor's notes describing joint pain, swelling, and specific functional limitations, not just general 'joint pain,' in both your own words and your provider's clinical observations.
- •Documentation of any incapacitating episodes or flare-ups, since these are what can raise a claim from the 10% to the 20% tier.
