Authorization and documentation: Prior authorization has been obtained as required by the plan

Phexx is not covered when used as a personal lubricant, for treatment of acute bacterial vaginosis, or for protection against HIV or other sexually transmitted infections. The product’s ingredients were previously marketed as an over‑the‑counter personal lubricant and Phexx is currently indicated only for prevention of pregnancy. Clinical data do not support its use for treatment of bacterial vaginosis, and Phexx labeling specifies that it does not protect against HIV or other STIs.

Use of Phexx for any indication other than prevention of pregnancy is considered not medically necessary. Examples of excluded uses include: (1) as a personal lubricant; (2) for acute episodes of bacterial vaginosis (evidence shows similar acid gels were less effective than standard treatment); and (3) for protection against HIV or other sexually transmitted infections.
