Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with diabetic peripheral neuropathy and a history of plantar ulceration presents to a podiatry clinic for evaluation of foot pain and recurrent callus formation. The clinician determines the patient would benefit from a custom molded plastazote shoe to offload pressure areas and protect healing tissue. The workflow includes an initial assessment (history, vascular and neurological exam), measurement and casting or 3D scan of the foot, fabrication of the L3253 molded plastazote shoe by orthotic lab personnel, a fitting visit to confirm fit and pressure relief, and follow-up visits to adjust padding and monitor ulcer healing and gait. Typical sites of service include podiatry clinics, orthotics/prosthetics offices, and outpatient hospital departments.
