C&P Exam Tips

1An active infectious disease is generally rated at 100% while active; once it resolves, it is rated at 0% and you are rated on the residual disability within the affected body system (38 CFR 4.88b) - claim each residual condition.

2Recurrence of active infection usually must be confirmed by culture, histopathology, or other diagnostic laboratory testing - make sure that confirmation is in your record.

3Identify and claim every residual (for example, arthritis, neuropathy, liver or kidney damage, or cognitive issues) - that is where most lasting compensation comes from after the active phase.

4For HIV-related illness (DC 6351), the rating turns on CD4/T4 cell count thresholds (for example, under 200, or 200-500) plus constitutional symptoms and opportunistic infections - bring your CD4 labs.

5Some infections carry presumptive long-term health effects under 38 CFR 3.317 - note any qualifying service exposure that supports the nexus.

6Report your worst days, list all medications and side effects, and describe how the illness and its residuals affect work and daily activity.
