Osteomyelitis Secondary to Amputation of Leg, with Defective Stump
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 Osteomyelitis when it develops after Amputation of Leg, with Defective Stump.
Why Osteomyelitis Is Linked to Amputation of Leg, with Defective Stump
Improper healing can leave stump vulnerable
Primary condition · VASRD 5163
Amputation of Leg, with Defective Stump
This code covers a below-knee amputation whose residual limb (stump) is defective enough that re-amputation through the thigh is recommended. What the code turns on is that recommendation, not the amputation level by itself, so documentation of how the stump fails is the core evidence.

Osteomyelitis
Osteomyelitis is infection of bone — usually reaching it through an open fracture, a penetrating wound, surgery or the bloodstream — which can smoulder for years, produce dead bone (sequestrum) and drain through a sinus tract to the skin. DC 5000 rates it on how active and how widespread the infection is, and on how recently there has been objective evidence of activity.
Osteomyelitis VA Rating Tiers
The VA rates Osteomyelitis the same way whether it's claimed directly or as secondary to Amputation of Leg, with Defective Stump — severity of Osteomyelitis itself determines the percentage.
| Rating | Criteria |
|---|---|
| 100% | Infection of the pelvis or spine, or spread into major joints or several sites, or continuous whole-body symptoms |
| 60% | Repeated flare-ups that make you systemically ill |
| 30% | Imaging or surgery shows dead bone or new bone walling it off |
| 20% | A draining sinus or other proof of active infection in the last five years, in recurrent disease |
| 10% | Quiet for five years but with a history of repeated episodes |
Example combined rating
60% Amputation of Leg, with Defective Stump + 30% Osteomyelitis = 72%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 60% and 30% combine to 72%, not 90%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Osteomyelitis Secondary Claim
- •Imaging or an operative report identifying an involucrum or a sequestrum by name — that finding alone is the 30 percent criterion.
- •Records of a discharging sinus or other objective evidence of active infection, dated, because the 20 percent criterion turns on activity "within the past 5 years".
- •A dated episode history, since Note (2) requires an established recurrent osteomyelitis for the 20 percent and "2 or more episodes following the initial infection" for the 10 percent.
- •Bone biopsy or deep culture results confirming the organism, plus hospitalization and debridement records.
- •Documentation of constitutional involvement — anemia, weight loss, debility, amyloid liver changes — which is what separates the 60 and 100 percent criteria from the rest, and which Note (1) exempts from the amputation rule.
- •Range-of-motion, shortening or nonunion findings for the affected bone, which are rated under their own codes and combined with the osteomyelitis rating.
