hyperbarics and debridement same day

How would you code for a physician who performed supervision of hyperbarics for a diabetic foot ulcer with osteomyelitis, and also debrided the wound to subcutaneous level (

99183, 11042-59 modifier?

What are your thoughts on the coder not submitting the 11042 because "insurance will not pay for hyperbarics and debridement?"

Thanks
