Nasal cavity and paranasal sinus cancer

For the 100% active-disease rating, medical records documenting an ongoing diagnosis of a rickettsial, ehrlichial, or anaplasma infection — such as lab results confirming the organism, hospitalization records, or treating-physician notes describing active symptoms — would reflect that criterion.

Once the disease resolves, the evidence that matters most is documentation of any lasting damage to specific body systems. Records showing effects on the bone marrow, spleen, central nervous system, or skin — such as lab panels, imaging, neurological exam findings, or specialist evaluations — help establish those residual conditions. Statements from you or people who know you describing how lingering symptoms affect your work or daily life can support the severity of those residuals. Each residual condition is then rated under the rules for its own body system.
