Patient eligibility
The Pharmaceutical Benefits Scheme (PBS) subsidises treatment with biological medicines under the National Health Act 1953, section 85 and section 100 for patients with complex refractory fistulising Crohn's disease.
Where the term 'biological medicine' appears, it refers to adalimumab, infliximab and ustekinumab.
Patients must be eligible for the PBS and meet the relevant restriction criteria.
The Schedule of Pharmaceutical Benefits on the PBS website outlines the restrictions for prescribing biological medicines.

These items are only PBS-subsidised for non-admitted patients, day admitted patients, or patients on discharge who are attending:
- an approved private hospital
- a public hospital.
These items aren’t PBS-subsidised for public hospital in-patients. You must include the hospital name and provider number on the authority application form.
Treatment specifics
To be eligible for PBS-subsidised treatment with biological medicines, patients must be treated by one of the following specialists:
