Nontuberculous mycobacterium infection

While you are in active treatment, medical records documenting the diagnosis and ongoing treatment are the core evidence for the 100% rating. When treatment ends, a VA examination is required, and that exam report becomes central to what happens next. If VA considers reducing your rating, the rules in 38 CFR 3.105(e) apply, so records showing your current condition at the time of any proposed change matter. If the infection recurs, laboratory evidence — such as culture results, histopathology reports, or other diagnostic test results — is required by the regulation to confirm that recurrence. For residual disabilities after the active infection resolves, the evidence that helps depends on which body system is affected. For example, pulmonary residuals would be supported by imaging and breathing test results, while skin residuals would be supported by dermatology records and exam findings. Statements from you about how residual symptoms affect your work and daily life can also support rating those residuals under their respective body system codes.
