Q&A Session – 21 October 2025
Q: If I am the admitting VMO for an ICU patient, who is the referring doctor?
- 🔍 Scope: This question relates to MBS referral requirements that apply to a small fraction of items claimed in ICU — in a setting, particularly in smaller hospitals, where intensivists may act as the primary admitting doctor.
🏥 The clinical scenario
- In most ICUs, patients are admitted under another specialist (e.g. physician or surgeon), with ICU providing supportive or consultative care.
- In these instances conventionally the referring doctor for ICU services is usually the admitting specialist.
- However, in smaller hospitals, patients may be:
- Admitted directly from the Emergency Department (ED) under the ICU specialist (e.g. admitting doctor),
- With another specialist only taking over care after ICU discharge.
- This is where the confusion around the admitting vs referring doctor often arises.
📄 Who is the referring doctor in this situation?
- ✅ If a referred service is performed while the patient is admitted under the intensivist (admitting doctor):
- The referring doctor can be the ED specialist who initially assessed the patient and requested the service.
- The referring doctor may also be another medical specialist in the hospital who requested the referred service.
- 🚫 The intensivist cannot refer to themselves.
🧾 Do ICU services ever require a referring doctor?
- ❌ Most ICU item numbers are non-referred services
- This means no referring doctor is required for admission, daily management, procedures or routine ICU care.
- ⚠️ Items that do require a referral:
- 🩻 Non self-determined Diagnostic imaging items (require a referral or diagnostic imaging request)
- 👨⚕️ Specialist consultation items

🔎 Practical application in ICU
- 🩻 Diagnostic imaging:
- Only relevant if the intensivist is performing imaging on the request of another practitioner.
- In reality, most imaging in ICU is self-determined as part of ongoing patient management → non-referred / non-requested.
- 👨⚕️ Specialist consultations:
- Typically relevant after ICU discharge, e.g.:
- TPN services
- Tracheostomy outreach
- In these cases, a referral is required, and the referring doctor is:
- The specialist who has taken over care on the ward
- If the Intensivist remains the admitting doctor after ICU discharge, the referring doctor would likely be the ED specialist
- Typically relevant after ICU discharge, e.g.:
⚠️ Important compliance points
- A referral is almost never required for ICU patients, but there are certain rare exceptions.
- If a referring doctor is required, details do not always need to be included in the claim submission, but:
- 📌 Referral must exist,
- 📌 It must be appropriately documented,
- 📌 It must be available if audited.
- Of routinely used ICU attendance items, only specialist/physician consultation items are referred services.
- 🚫 The following attendances are non-referred services:
- Emergency attendance items (160–164)
- Goals of care planning (13899)
🧩 Practical takeaway
- ⚠️ Admitting VMO does not always equal referring doctor
- In ICU, most services are non-referred, but when a referral is required:
- It must come from an independent practitioner (other than the Intensivist),
- And be clearly documented, even if not submitted.
