Several schemes are in place offering financial reimbursement for travel costs for treatment.The Patient Travel Expenses Scheme (PTES) is Scotland-wide and provides support to those in receipt of certain benefits.The Highlands and Islands Travel Scheme (HITS) reimburses the travel costs of everyone in the Highlands and Islands area required to travel more than 30 miles to a hospital by road or 5 miles by air or land, less the first £10 (unless in receipt of certain benefits).Under the discretionary scheme, NHS Boards may also choose to reimburse patient travel expenses to those not eligible under PTES or HITS where it is viewed to be an extension of treatment costs and deemed to be clinically necessary.
