Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who has undergone a traumatic partial hand amputation with preservation of the thumb or a single finger and requires a custom prosthetic glove and partial hand restoration. The patient presents to a prosthetics clinic after surgical wound healing and stump maturation (usually 6–12 weeks post-amputation). The multidisciplinary workflow includes an initial prosthetics evaluation by a certified prosthetist and an occupational or hand therapist: history and functional goals are documented, stump measurements and skin assessment are performed, and casting or digital scanning is completed. A custom glove or soft-sock interface is fabricated, followed by try-in visits for shading, fit adjustments, and dynamic alignment. Final delivery includes patient education on donning/doffing, care, and follow-up for adjustments. Typical sites of service are outpatient prosthetics clinics, hospital-based prosthetics departments, and specialty orthotics and prosthetics (O&P) offices. The service described by L6900 is the provision and fitting of a partial-hand restoration prosthesis, inclusive of casting, shading, and measurements, for a patient with the thumb or one finger remaining.
