How Pathology Billing Works in Australia
When you get a blood test in Australia, two separate services are being billed: the GP consultation (where you get the referral) and the pathology tests themselves (performed by the lab). Each can be billed independently, which is why some patients receive unexpected bills.
Bulk billing means the healthcare provider (GP or pathology lab) bills Medicare directly and accepts the Medicare rebate as full payment. You pay nothing. This is different from a gap fee, where the provider charges more than the Medicare rebate and you pay the difference.
The two billing decisions:
1
GP visit
Your doctor decides whether to bulk bill the consultation. Most GPs bulk bill children, concession card holders, and pension card holders. Many also bulk bill all patients.
2
Pathology tests
The lab decides whether to bulk bill the tests. Most large pathology providers bulk bill all Medicare-eligible tests. Some smaller or specialist labs charge gap fees for certain tests.
The GP writes a pathology request form listing the tests they want. Each test maps to a Medicare Benefits Schedule (MBS) item number. The lab processes the tests, claims the Medicare rebate, and — if they bulk bill — sends you no invoice. If the lab does not bulk bill a particular test, they will send you a bill for the gap between what they charge and what Medicare rebates.
Tests That Are Always Bulk Billed
These routine tests are covered by Medicare whenever your GP orders them with a valid referral. No special clinical reason is required beyond your doctor's clinical judgement that the test is appropriate. At a bulk-billing pathology lab, you will pay nothing.
| Test | MBS Item | Condition |
|---|---|---|
| Full Blood Count (FBC) | 65070 | GP referral only |
| Urea, Electrolytes, Creatinine (UEC) | 66512 | GP referral only |
| Liver Function Tests (LFTs) | 66512 | GP referral only |
| Thyroid Stimulating Hormone (TSH) | 66716 | GP referral only |
| Lipid Panel (Cholesterol) | 66500 | GP referral; once per 12 months or if high risk |
| Fasting Glucose | 66500 | GP referral only |
| HbA1c | 66551 | Diagnosis or monitoring of diabetes |
| Iron Studies (Ferritin, Transferrin) | 66596 | GP referral; if symptomatic or monitoring |
| ESR (Erythrocyte Sedimentation Rate) | 66500 | GP referral only |
| CRP (C-Reactive Protein) | 66695 | GP referral only |
| Calcium / Phosphate / Magnesium | 66512 | GP referral only |
| Uric Acid | 66512 | GP referral only |
| Folate | 66596 | GP referral; if symptomatic |
| INR / Coagulation | 65120 | Warfarin monitoring or clinical suspicion |
Note: "GP referral only" means your doctor simply needs to write the test on a pathology request form. No additional clinical justification is needed for Medicare to cover it.
Tests That Need a Clinical Reason
These tests are covered by Medicare, but only when there is a documented clinical indication. Your GP needs to have a valid medical reason and, in some cases, must note the indication on the request form. Without the right clinical context, the lab may charge you privately.
| Test | MBS Item | When Medicare Covers It |
|---|---|---|
| Vitamin D (25-OH) | 66608 | Only if at risk: osteoporosis, malabsorption, dark skin, covering clothing, institutionalised, or proven deficiency being monitored |
| Vitamin B12 | 66596 | Symptomatic: fatigue, neurological symptoms, macrocytic anaemia, vegan/vegetarian, elderly |
| Free T4 / Free T3 | 66719 | Only if TSH is abnormal first; not as a screening test |
| Testosterone (Total) | 66695 | Symptomatic: fatigue, low libido, reduced muscle mass; requires clinical indication |
| Oestradiol / LH / FSH | 66695 | Fertility investigation, menstrual irregularity, suspected menopause (age <45) |
| PSA (Prostate-Specific Antigen) | 66655 | Men 50+, or 40+ with family history; requires informed consent discussion |
| Cortisol (Morning) | 66695 | Clinical suspicion of Cushing's or Addison's disease |
| Coeliac Screen (tTG-IgA) | 71163 | Symptomatic: chronic diarrhoea, bloating, weight loss, iron deficiency |
| ANA (Autoimmune Screen) | 71163 | Clinical suspicion of autoimmune disease |
| HLA-B27 | 71163 | Clinical suspicion of ankylosing spondylitis |
| Fasting Insulin | 66542 | Strong clinical indication — rarely bulk billed |
The vitamin D trap
Vitamin D is the test that surprises the most patients. In 2014, Medicare restricted bulk billing of vitamin D to patients who are genuinely at risk of deficiency. If you ask your GP for a "routine vitamin D check" without symptoms or risk factors, it may be charged privately ($30-$50). Risk factors that qualify for bulk billing include: diagnosed osteoporosis or osteopenia, malabsorption conditions (coeliac, Crohn's, gastric bypass), dark skin, covering clothing for cultural reasons, housebound or institutionalised patients, and confirmed deficiency being monitored.
Tests Never Covered by Medicare
These tests do not have an MBS item number, which means they can never be bulk billed regardless of your clinical situation. You will always pay out of pocket. Some of these tests are also not supported by mainstream evidence, which is why Medicare does not cover them.
| Test | Why Not Covered |
|---|---|
| Food Intolerance Panel (IgG) | Not evidence-based; never covered by Medicare |
| AMH (Anti-Mullerian Hormone) | Fertility planning; always private ($60-$100) |
| Comprehensive Hormone Panel | Wellness/biohacking panels; always private ($150-$400) |
| Genetic / Genomic Tests | Most pharmacogenomics and lifestyle genetics; not MBS listed |
| DUTCH (Dried Urine) | Functional medicine test; not MBS listed ($300-$500) |
| Microbiome / Stool Analysis | Functional medicine test; not MBS listed ($200-$400) |
Common Tests That Surprise People
Vitamin D
Was previously free for everyone. Now requires documented risk factors. Many GPs still order it routinely, and some patients get billed $30-$50 unexpectedly when the lab rejects the Medicare claim.
Free T4 / Free T3
Medicare requires a two-step process: TSH is tested first, and T4/T3 are only covered if the TSH result is abnormal. If your GP orders FT4 without an abnormal TSH on record, the lab may charge you privately.
Testosterone
Medicare covers testosterone testing when there are symptoms like fatigue, reduced libido, or muscle wasting. Ordering it for general wellness or gym optimisation is not covered. Some labs will bill privately if the indication is vague.
Fasting Insulin
Unlike fasting glucose (always covered), fasting insulin requires a very strong clinical indication — usually suspected insulinoma or specific endocrine investigations. Most GPs cannot get this bulk billed for routine metabolic screening.
PSA (Prostate)
PSA testing is covered by Medicare, but GPs are expected to have an informed consent discussion about the benefits and harms of screening before ordering it. Some GPs are reluctant to order it without symptoms due to the risk of overdiagnosis.
Oestradiol / Progesterone
Medicare does not cover hormone testing to confirm menopause in women aged 45+, because diagnosis is clinical (based on symptoms and age). Hormone panels for menopause are only covered in women under 45 with suspected premature menopause.
How to Avoid Unexpected Costs
1
Ask your GP if they bulk bill
Not all GPs bulk bill consultations. Before booking, call and ask. If your GP charges a gap fee for the consultation, the pathology tests may still be bulk billed separately by the lab.
2
Ask the pathology lab if they bulk bill
Call the collection centre before your appointment. Most major chains (Laverty, QML, Sullivan Nicolaides, Melbourne Pathology, Dorevitch) bulk bill all routine tests. Smaller specialty labs may not.
3
Take your request form to a different lab if needed
You are not required to use the pathology lab attached to your GP clinic. Your referral form is valid at any accredited lab. If the in-house lab charges gap fees, take the form to one that bulk bills.
4
Tell your GP about your symptoms — honestly
For conditionally covered tests (vitamin D, B12, testosterone), your GP needs a documented clinical reason. Be open about symptoms like fatigue, bone pain, mood changes, or dietary restrictions. This is not gaming the system — it is providing the clinical information your doctor needs.
5
Ask your GP to check which tests need special indication
A good GP will tell you if any test on your form might not be bulk billed. If you are budget-conscious, ask them to flag any tests that could attract a private fee so you can make an informed decision.
6
Consider a Medicare Health Assessment
Australians aged 45-49 are eligible for a free Health Assessment (MBS item 701/703), and those 75+ get annual assessments. These include comprehensive blood panels at no cost. Aboriginal and Torres Strait Islander Australians can access health assessments from age 25.
7
Use your Health Care Card or Pension Card
If you hold a Health Care Card, Pension Card, or Commonwealth Seniors Health Card, most GPs and pathology labs will bulk bill you. Always bring your card to appointments.
State-by-State Pathology Providers
Australia's pathology industry is dominated by three large groups — Sonic Healthcare, Healius, and Australian Clinical Labs — plus government-run services in several states. Government labs always bulk bill. Private labs usually bulk bill routine tests, but it is worth confirming, especially for conditionally covered tests.
| State | Major Providers | Bulk Bills? | Notes |
|---|---|---|---|
| QLD | QML Pathology, Sullivan Nicolaides | Yes (most sites) | QML part of Healius; SNP part of Sonic |
| NSW | Laverty, Douglass Hanly Moir | Yes (most sites) | Both part of Healius/Sonic groups |
| VIC | Melbourne Pathology, Dorevitch | Yes (most sites) | Melbourne Path part of Sonic; Dorevitch part of Healius |
| SA | Clinpath, SA Pathology | Yes | SA Pathology is government-run; always bulk bills |
| WA | PathWest, Western Diagnostic | Yes | PathWest is government-run; always bulk bills |
| TAS | TML Pathology | Yes | Government-run; always bulk bills |
| ACT | Capital Pathology, ACT Pathology | Yes (most sites) | Capital Pathology is private; ACT Pathology is government |
| NT | Western Diagnostic Pathology | Yes | Limited collection centres in remote areas |
| Nationwide | Australian Clinical Labs (ACL) | Yes (most sites) | Third-largest provider; operates across multiple states |
Government-run laboratories (SA Pathology, PathWest, TML) always bulk bill because they are publicly funded. Private laboratories may change their billing arrangements, so always confirm before your appointment.
Your Rights as a Patient
You can choose your pathology lab
Your GP gives you a referral form. You can take it to any accredited laboratory in Australia. You do not have to use the one co-located with the medical practice.
You can ask for costs upfront
Pathology labs are required to inform you of any out-of-pocket costs before performing the tests. If a lab cannot confirm bulk billing, ask for a written quote.
You can request a copy of all your results
Under the Privacy Act, you have a right to access your own health records, including pathology results. Most labs now provide online patient portals where you can download your results as PDFs.
You can dispute unexpected charges
If you were not informed about gap fees before your test, you can lodge a complaint with the Health Care Complaints Commission in your state. You can also contact the Pathology Awareness Australia helpline.
You can request your GP update the clinical indication
If a test was rejected for bulk billing because the indication on the form was insufficient, your GP can sometimes amend the request. This is worth discussing if you received an unexpected bill.
Frequently Asked Questions
Are all blood tests free with Medicare in Australia?
No. Most routine blood tests ordered by a GP are bulk billed under Medicare, meaning they are free to the patient. However, the pathology lab must choose to bulk bill, and some tests require a valid clinical reason before Medicare will cover them. Tests like food intolerance panels, some genetic tests, and comprehensive hormone panels are never covered by Medicare.
What is the difference between the GP bulk billing and the pathology lab bulk billing?
These are two separate billing decisions. Your GP bills Medicare for the consultation (the appointment). The pathology lab separately bills Medicare for the tests themselves. Your GP may bulk bill your visit, but the lab could still charge a gap fee for the tests. Always ask both your GP and the lab whether they bulk bill.
Why did I receive a bill even though my GP said the blood test was free?
The most common reason is that the pathology lab does not bulk bill, even though your GP does. Another possibility is that the test required a specific clinical indication that was not documented on the request form. Less commonly, you may have exceeded a frequency limit — for example, Medicare covers a vitamin D test once per 12 months for qualifying patients, and a repeat within that window may be charged privately.
Can I choose which pathology lab does my blood test?
Yes. Your GP writes a pathology request form that you can take to any accredited pathology laboratory. You are not required to use the collection centre attached to the medical practice. If bulk billing is important to you, call ahead and confirm that the lab you plan to visit bulk bills Medicare for the specific tests on your form.
How do I know which tests on my pathology form are bulk billed?
The pathology request form lists the tests your GP has ordered, but it does not usually indicate pricing. The lab determines billing at the time of processing. Most labs bulk bill all routine tests (FBC, UEC, LFTs, thyroid, lipids). If you want certainty, call the lab before your appointment and read them the tests listed on your form.
Are blood tests free at public hospital emergency departments?
Yes. Blood tests performed as part of treatment in a public hospital emergency department or during an inpatient stay are free under Medicare, regardless of the tests ordered. However, if a hospital outpatient clinic refers you to an external pathology lab, the normal Medicare bulk billing rules apply.
Can I get blood tests without a GP referral?
Some private services (like iMedical) allow self-referral, but these are never bulk billed. You will pay full price, typically $50-$300 per panel. A bulk-billed GP visit gives you free access to Medicare-funded tests.
How often can I get free blood tests?
Most routine tests can be repeated as often as your GP deems clinically necessary. Some have frequency limits: lipids every 12 months (unless high risk), vitamin D every 12 months (if qualifying), HbA1c every 3-6 months (diabetics).
What if I do not have a Medicare card?
Without Medicare, you pay privately for all blood tests. Options include public hospital emergency departments (free for emergencies), community health centres, and Aboriginal and Torres Strait Islander health services. International students should check their OSHC policy.
Can I claim blood tests on private health insurance?
Standard hospital and extras cover does not usually reimburse outpatient pathology. Some top-tier extras policies cover limited pathology, but it is rare. Check your specific policy.
