Scenario lineage

v1No parent version

Japanese national fee schedule, code K082-8 robotic TKA at 42,190 points against 37,690 points for conventional K082, a premium of 4,500 points or about 45,000 yen per case at 10 yen per point. Surgical fees effective 1 June 2026. Japan is the only market in this study where the robotic increment is reimbursed, which inverts the economics: the model here is a revenue premium, not a cost offset. The facility standard sets a regulatory volume floor of 5 cases a year for new notification and 10 for renewal, so volume is a condition of payment rather than only a driver of amortisation.

Inputs

Annual procedure volumecases / yrLinked to annual volume metric; adjust as a user assumption.Incremental payment per caseJPYSourced from the fee schedule answer — zero where no robotic component is paid.Incremental case costJPYUser assumption — no approved local cost study is held.Fixed programme costJPYUser assumption — capital, service and training over the scenario period.Scenario periodyearsUser assumption.

Implant economics are excluded unless externally supported for this market.

Contribution per case

JPY -500

= incremental payment − incremental case cost

Break-even cases

Not reachable

= fixed programme cost ÷ contribution per case

Contribution per case is not positive, so no case volume repays the programme cost.

Annual contribution

JPY -150,000

= contribution per case × annual volume

Period contribution

JPY -1,750,000

= (annual contribution × years) − fixed programme cost

Sensitivity — incremental case cost
