CGH and FSMC should have terminals that offer loan vouchers for cyberlimbs bought and installed on their premises. This offers people a payment plan to pay for expensive cyberlimbs over time, and extensions can be requested similarly to WJF fines.
Failure to pay puts the patient name and details on a board with a reward for reposessed cyberlimbs. If someone loses the cyberlimb, maybe by dying, they can apply to pay it off at a higher price than before. Failing to pay -that- puts them on a bounty board.
