Report TCOM Without ABI as Unlisted

Question: Please suggest an appropriate code for a transcutaneous oxygen measurement test when ankle/brachial indices are not done. Can we report this with code 93922 or is this procedure best reported with an unlisted code 93998?

Answer: For the procedure being described, you can best report code 93998 (Unlisted noninvasive vascular diagnostic study). If your physician had performed ankle/brachial indices (ABI) as well as transcutaneous oxygen tension measurements (TCOM), then you could report 93922 (Limited bilateral noninvasive physiologic studies of upper or lower extremity arteries, [e.g., for lower extremity: ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus bidirectional, Doppler waveform recording and analysis at 1-2 levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus volume plethysmography at 1-2 levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries with transcutaneous oxygen tension measurements at 1-2 levels).
