The proposed 2017/19 National Tariff Payment System would result in small changes to revenue for most providers, with around 70% seeing changes of less than 1%. Specialist trusts could see larger changes, with some seeing changes greater than 2.5%. The document provides an overview of key proposed changes including moving to HRG4+, increasing prices for more complex cases, raising funding for specialised services, changing outpatient tariffs to encourage first appointments, and revising maternity and best practice tariff prices. Providers and commissioners are encouraged to analyze the potential impacts and work together to ensure services are delivered in the most appropriate setting.
