Medicare Pays Nearly Half a Dietitian on a GP Plan. Vitamins Skip the Pre-Sale Check

Dietitian vs supplements on a Medicare plan

Medicare item 10954 covers a dietitian visit of at least 20 minutes for a patient whose GP has written a chronic condition management plan. The schedule fee is $74.55 and Medicare pays 85% of it, $63.40, according to MBS Online. Set that rebate against a typical dietitian consult ($130) and Medicare covers nearly half the fee, leaving a $66.60 gap at Going Rate's prices.

A typical naturopath consult ($160) carries no Medicare rebate. Against the rebated dietitian gap it costs 2.4 times as much out of pocket at Going Rate's prices. Without a GP plan, the naturopath is about 23% dearer than the full dietitian fee.

The rebate depends on the plan. You need a chronic condition and a GP to write the plan, and MBS Online caps the rebate at five allied health visits a calendar year, shared across every allied health provider you see. Most people buying vitamins as a general health habit will pay the full dietitian fee.

How the TGA handles listed vitamins

The TGA says listed medicines, the ones carrying an AUST L number, include products made with vitamins, minerals, herbs and fish oil. It says listed medicines are not individually assessed by it before supply, and that sponsors self-certify they meet the safety, quality and efficacy requirements. The company selling the product vouches for the claim on the label.

The TGA checks afterwards, through compliance reviews. It says about 12,000 medicines are listed at any one time, more than 1,000 are newly listed each year, and it selects only some of them for review.

Dr John McEwen measured how small that selection is, in a study published in the RACP's Internal Medicine Journal. Of about 3,000 products newly listed in 2022 and 2023, the TGA had published efficacy assessments for 62, or 2%. In 33 of those 62, the sponsor did not hold substantial evidence of efficacy. The study also found the TGA has not published a random review report since late 2018.

Shoppers assume someone checked

A CHOICE survey of 1,052 people, last updated in 2018, found 80% had never noticed the AUST L or AUST R number on a medicine label. Of the 142 people who knew the codes were there, 43% wrongly believed listed products had been evaluated for effectiveness.

Complementary Medicines Australia, the industry body, reported in its 2025 snapshot that 84% of Australians are confident in the safety and quality of supplements. The TGA makes no pre-sale finding on whether a listed product works.

What happens when the TGA asks for the evidence

The TGA reviewed 10 listed vitamin D products making bone strength claims. The evidence did not support the claim for any of the 10, and 4 were cancelled from the register. A review of 21 magnesium products claiming to improve exercise performance found 16, or 76%, had insufficient evidence, and 10 were cancelled.

Large trials have found little for healthy people. The Australian D-Health trial gave 21,315 Australians aged 60 and over a monthly vitamin D dose or a placebo for five years. Death rates in the two groups showed no meaningful difference (hazard ratio 1.04), Neale and colleagues reported in 2022.

A 2022 evidence review for the US Preventive Services Task Force, published in JAMA, covered 84 studies and nearly 740,000 people. It found vitamin and mineral supplements gave little or no benefit in preventing cancer, cardiovascular disease and death, apart from a small drop in cancer rates with multivitamins.

Naturopath vs dietitian prices

The federal Natural Therapies Review 2024, released by the Department of Health in March 2025, rated the evidence for naturopathy as low certainty. For 44 outcomes it judged critical or important, the effect remains unknown because the reviewers found no studies. The report cites a survey in which about 65% of Australian naturopaths said they prescribe nutritional supplements.

Private health insurers have been allowed to cover naturopathy again since 1 July 2025, the Department of Health says, and each insurer decides whether to cover it, when, and how much to pay. Rebates vary by fund and policy, so we have not netted any off the naturopath fee ($160).

On full fees, a naturopath consult ($160) costs about 23% more than a dietitian consult ($130) at Going Rate's prices. On a GP plan the gap widens to 2.4 times. Any supplements a naturopath prescribes are a separate bill, and we found no reliable figure for what that bill typically runs to.

What a year of rebated dietitian advice costs

Five plan-funded dietitian visits leave $333 out of pocket at Going Rate's prices, with Medicare paying $317 across the year. That is less than a single month of one-on-one personal training ($570) and under a fifth of a year of gym membership ($1,900). A medical weight-loss program ($3,750) costs about 11 times as much, all at Going Rate's prices.

The five visits are shared. A patient also seeing a physiotherapist ($130) or an exercise physiologist ($100) on the same plan draws from the same five a year.

Harnett and colleagues, writing in BMJ Open in 2019, found complementary medicine users spent an average of about $86 a year on vitamin and mineral supplements, in spending measured over 2016 and 2017. At Going Rate's prices, one full-fee dietitian consult ($130) costs about a year and a half of that spend.

Who buys supplements, and when they make sense

Supplement use climbs with age and is higher among women. The ABS found 33.6% of Australians aged 2 and over took a dietary supplement in the previous 24 hours in its 2023 survey, up from 28.5% in 2011-12. Adult women were at 43.7% against 30.8% of men, and 50.9% of people aged 75 and over took one against 24.5% of 18 to 29 year olds.

Complementary Medicines Australia, the industry body, puts the vitamins and dietary supplements segment at $2.84 billion in 2025, with 61% of sales, $1.73 billion, going through pharmacies.

Low iron or low vitamin D found on a blood test is a clinical question for a GP. A patient with a chronic condition can take it to a dietitian ($130) on a GP plan, with Medicare paying nearly half the visit at Going Rate's prices.
