Total inability to detect odors or scents.
To support a rating under this code, evidence needs to show that your sense of smell is completely absent. Medical records documenting a diagnosis of anosmia (complete loss of smell) are central to this. Results from smell-testing evaluations performed by a physician or specialist can directly confirm the complete absence of smell function. Notes from VA or private medical examinations that describe your inability to detect any odors are also relevant. Statements from you describing your complete inability to smell in daily life — such as being unable to detect smoke, food, or other odors — can help support the medical findings. Because the regulation covers only complete loss, evidence showing partial loss would not meet the criteria for this code.
