naltrexone injection

A #15 blade was used to make a 2cm long incision. A deep subcutaneous pocket, 2cm wide and 5cm long was made using a 12 mm trocar. The naltrexone pellets were then inserted into the pocket via a self contained ejection syringe.

I came up with 17999 unlisted, skin, subcutaneous tissue

has anyone attempted to code a naltrexone placement?
