Treatment Function Codes

Treatment Function Codes (TFCs) and Main Specialty Codes are used to support the national reporting and analysis of clinical workforce activity throughout the NHS and through data sets such as the Commissioning Data Sets (CDS).  

TFCs are used to record, report on, extract and flow activities undertaken, irrespective of the type of healthcare professional who performs them.

The Main Speciality Code is the specialty within which a consultant is recognised or contracted to the organisation and is usually aligned to specialities recognised by the royal colleges, faculties and the General Dental Council.

The Treatment Function and Main Speciality Standard covers the respective classifications.


Request new codes

To requests a new TFCs or to request an amendment to an existing TFC  please email [email protected]

We are in the process of developing a new portal to help process submissions in the future.  Further information about this will be available soon. 

All requests for new codes will be assessed against the current Treatment Function eligibility criteria.


Treatment Function Maintenance Group

The Treatment Function Maintenance Group (TFMG) act as the expert reference group and are responsible for considering and approving change requests against the Treatment Function eligibility criteria. They review the Treatment Functions to make sure they continue to be clinically relevant.

This group is made of people who work within NHS trusts, NHS Digital, NHS England and NHS Improvement. 

Any proposed changes to Treatment Functions will need to be agreed by the TFMG using the Treatment Function eligibility criteria.

We do not expect the TFMG to meet until 2021 because of ongoing Coronavirus (COVID-19) work.
