Secondary Condition Claim · VASRD 9400
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 Generalized Anxiety Disorder when it develops after Knee Replacement (Prosthesis).

Primary condition · VASRD 5051
Knee Replacement (Prosthesis)
This code rates a knee replacement based purely on ongoing severity after surgery - unlike a related knee replacement code that includes an automatic one-year 100% rating right after the procedure, this version rates directly on your post-surgical pain, weakness, and function from the start.
Secondary condition · VASRD 9400
Generalized Anxiety Disorder
GAD is a mental health condition marked by persistent, excessive worry about daily activities.
The VA rates Generalized Anxiety Disorder the same way whether it's claimed directly or as secondary to Knee Replacement (Prosthesis) — severity of Generalized Anxiety Disorder itself determines the percentage.
| Rating | Criteria |
|---|---|
| 100% | You can't work or maintain relationships due to extreme anxiety symptoms. |
| 70% | Severe anxiety that disrupts your work and social life. |
| 50% | Frequent anxiety that affects your job and motivation. |
| 30% | Mild anxiety that causes some issues at work or home. |
| 10% | Anxiety that's under control or only shows up under pressure. |
Example combined rating
60% Knee Replacement (Prosthesis) + 50% Generalized Anxiety Disorder = 80%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 60% and 50% combine to 80%, not 110%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
