Does CIGNA have it in their plan that a surgical avulsion of a toenail is routine foot care?

This is my first thought, what diagnosis did you use exactly use to justify this procedure, a S diagnosis? This minor procedure CPT 11730 requiring anesthesia is a procedure and then removal of a nail for a traumatic injury CIGNA should pay but again what was diagnosis code paired with the CPT 11730.  Each plan has different aspects that the employer may and may not cover. Ask CIGNA for the specific insurance your patient had for their plan summary document as each employer picks what is covered as an ERISA plan, unfortunately certain codes may be excluded. If not covered it is patient responsibility.
