I was rated 30% sinusitus 3 years ago based on antibiotic usage (more than 3 times year). About 18 months ago, I has sinus surgery due to chronic infection. Sicne the surgery, I continue to have frequent infections. My recent ct scan showed complete soft tissue opacification of the left medial antrostomy. Later this month, I will have surgery again (NSE maxillary Anstrostomy w/removal tissue).. Does this justify an increase to 50%?
