A referral is required for most specialist services. A referral can be Standard, Non-Standard or Indefinite
A standard referral by default is for a period of 12 months from a GP or 3 months from another specialist, unless it’s for an admitted patient. Referrals from another specialist for admitted patients are valid for 3 months or for the duration of admission, whichever is longer.
Only use non-standard when the referring GP has specified a different period.
Rarely a GP referral can be indefinite where a patient needs continuing care for a specified chronic condition.
You should almost always use a standard referral with a start date in the appropriate timeframe. The referral starts from the date the specialist first meets the patient, not the date issued.
Anaesthetists
Generally, in-patient services can have a referral type of Hospital. The exception is referred consultations such as item 17640 which needs standard referral details.
