Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.

Where the denial was overturned

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for balloon ostial dilation of the maxillary sinus x 2, balloon ostial dilation of the frontal and sphenoid sinuses x 2, nasal/sinus endoscopy, surgical with ethmoidectomy x 2. Balloon dilation of the sinuses (BDS) is typically performed for the treatment of either recurrent acute (RARS) or chronic rhinosinusitis (CRS). The ostiomeatal complex (OMC) is a particularly important concept in functional endoscopic sinus surgery (FESS). It represents the common drainage pathway for the frontal sinus, anterior ethmoid air cells, and maxillary sinus into the middle meatus. Surgical correction of OMC obstruction requires both the widening of the maxillary sinus ostium and the taking down of the anterior ethmoid air cells.

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for balloon ostial dilation procedure of the bilateral frontal and sphenoid sinuses. Balloon sinus dilation is typically performed for either recurrent acute rhinosinusitis (RARS) or chronic rhinosinusitis (CRS). Balloon sinus dilation offers a significant benefit over traditional functional endoscopic sinus surgery (FESS) as it carries less morbidity and can frequently be accomplished in an office setting. Balloon sinus dilation should only be recommended to patients who meet the strict diagnostic criteria for rhinosinusitis and who are refractory to maximal medical management.
