Skin Perfusion Pressure Testing

Date: Oct 21, 2019

Question:

What would the CPT code be for skin perfusion pressure testing? Report states "Skin perfusion pressure testing was performed of the left lateral foot to assess tissue perfusion at the location of the patient's wound. The contralateral right lateral foot was evaluated for comparison. Impression: Skin perfusion at the lateral plantar surface of the right foot is 75 mmHg, and at the lateral plantar surface of the left foot it is 67 mmHg. These values indicate adequate perfusion for healing." I have considered 93998, but since it wasn't a true vascular study I am wondering if a low level EM would be more appropriate?
