I have a physician who placed an ALT flap on a patient’ foot/ankle to cover an open non-healing wound. 9 months later the flap is healthy and ok but the patient is unable to wear many kinds of shoes due to excess bulk in the flap. Our surgeon used S.A.F.E. Liposuction and a little bit of cutting to remove excess bulk from the flap to help the patient fit into shoes better. Since this wasn’t cosmetic and was a function problem of reconstruction it should be covered by insurance but the provider didn’t do a prior authorization and is now wondering what CPT code to use. The liposuction codes don’t have RVU values and are not paid by any insurance companies in our area. 15620? even though it was mostly liposuction? Other suggestions?
