CPT 29705: Removal or Modification of Full Arm or Leg Cast
Medicare pays $71 and commercial payers pay $148 on average nationally for this procedure.
CPT code 29705 describes removal or modification of an existing full-arm or full-leg cast when the cast is no longer required, requires replacement, or has become too tight from swelling; this is a cast management service typically performed by an orthopedic or trauma clinician in an outpatient clinic, urgent care, emergency department, or ambulatory procedure setting and involves manual cast cutting, splitting, trimming, or replacement of the cast material as clinically indicated.
