Malignant neoplasm of maxillary sinus
VA doesn't add ratings together. It combines them using the table in 38 CFR § 4.25, so two ratings usually total less than their sum.
During active disease and treatment, medical records confirming the malignant diagnosis and documentation of ongoing or recently completed treatment are the core evidence. Pathology reports, imaging studies, oncology notes, and treatment records all show that the condition and its treatment are active, supporting the 100% rating.
After treatment ends, the mandatory VA examination six months later will look for signs of local recurrence or metastasis. Imaging results, oncology follow-up notes, and lab findings that address whether the cancer has returned or spread are directly relevant at that stage. If there is no recurrence or metastasis, the rating shifts to residuals. At that point, medical records and examination findings documenting lasting effects — such as breathing difficulties, structural changes, pain, or other functional losses — become the evidence that shapes your rating. Statements from you and people who know you, describing how any remaining symptoms affect your daily life and ability to work, can help show the severity of those residuals.
