99211 can be used to report a dressing done in conjunction with evaluation of a wound when performed ‘incident to’ a physician’s plan of care. It’s often used this way in wound care centers.
If this is being done in a facility by hospital-employed therapists acting on physician orders, it’s fine, since the code will be billed only by the facility. If it’s in an office, then it needs meet all of the ‘incident to’ requirements, including that the therapists be employed and supervised by the physicians. Therapists may not independently bill for this service.
