TREATMENT FUNCTION CODE

TREATMENT FUNCTION CODE is a unique identifier for a TREATMENT FUNCTION.

TREATMENT FUNCTION CODE is recorded to report the specialised service within which the PATIENT is treated.

It is based on MAIN SPECIALTY but also includes approved sub-specialties and treatment specialties used by lead CARE PROFESSIONALS including CONSULTANTS.

TREATMENT FUNCTION, rather than the Royal College or Faculty specialty, is required on most activity returns and in the Commissioning Data Sets.

TREATMENT FUNCTION CODES should be used for all aggregate Central Returns unless otherwise stated eg National Workforce Data Set uses MAIN SPECIALTY CODES.

GENERAL MEDICAL PRACTITIONER, NURSE and Allied Health Professional/ Biomedical Scientist/ Clinical Scientist ACTIVITY should be recorded against the TREATMENT FUNCTION under which the PATIENT is treated.

Joint Consultant Clinic ACTIVITY should be recorded against the TREATMENT FUNCTION which best describes the specialised service.
