This local sub specialty code is a separate field, rather than an extension.

For Referral to Treatment Times (Combined):-

- Local Sub Specialty must always be submitted, noting that ‘000’ means no appropriate Local Sub Specialty;

- Codes for “Assessment” activity (i.e. 666, 166, 266, 366, and 966) are not permissible in the RTT (Combined) return.
