It involves lots and lots of paper (reports, treatment etc)

Different areas and insurance companies require a variety of claim forms. (UB's, CMS 1500, Local carriers in house forms, etc)
Difficult to file electronically (due to paperwork)

Many will accept faxed claims

Can be a very high dollar value per claim form.

Reimbursement varies. Very tough and long term to get uninsured reimbursement.

are you thinking of taking on an ambulance client?
