Replacement of a DME, Orthotic or Prosthetic Item

Correct Use

  • Append to replacement claims (to first month rental claim) for a capped Durable Medical Equipment (DME), prostheses and orthoses rental item. Circumstances warranting replacement of these items may include loss, theft or irreparable (not all inclusive)

  • Append to claims for replacement of supplies (refills)
