The federal government is promising a new scheme to support patients with chronic diseases that includes extra funds for flexible care models that include non face-to-face consultations with the patient's general practice.

Yesterday's federal budget promised $448.5 million over three years from next year for the voluntary enrolment scheme, which will initially be aimed people over 70 but will be available for high-needs patients.

It will allow general practices to provide consultations, referrals, scripts and test results remotely, with usual services continuing to be rebatable for the patient under Medicare.
