Q&A Session – 21 October 2025

Q: For an on-call with overnight admission after midnight — what items can I bill?

  • 🔍 Scope: This overnight admission scenario highlights the mismatch between MBS calendar-day billing rules and real-world ICU rostering and on-call arrangements.

🌙 The common scenario

  • You are on-call overnight (e.g. Sunday night), but not the rostered intensivist for the following day.
  • A patient requires an overnight stay admission to hospital ICU in the early hours after midnight.
  • The question arises: who bills the ICU daily management items in an overnight admission situation?

🧾 ICU daily items — strict calendar day rules

  • ICU daily management and monitoring items (e.g. 13870, 13873) are:
    • 🗓 Based on a calendar day (midnight to midnight)
    • 👤 Claimable by one intensivist only per patient per day

  • 🚫 There are no separate items for callbacks or on call overnight attendance — all attendances are considered part of the daily item.

🤝 Practical solution in real-world practice to overnight admission in ICU

  • In most cases, overnight admission scenarios are often managed via a “gentleman’s agreement”:
    • The intensivist who performs the morning ward round (i.e. the rostered intensivist for that day) typically claims the daily item.
    • The intensivist who was on call overnight does not claim the daily management item.

🔧 What can you claim during an overnight admission?

  • ✅ Procedures:
    • Any procedures you personally perform or supervise during overnight admission are fully claimable.

  • 🚫 Emergency attendance items (160–164):
    • These are not routinely applicable when you are attending instead of the rostered intensivist and/or as part of on-call.
    • They are only claimable if you are attending in addition to the primary intensivist and the patient is in imminent danger of death.

⚠️ Important caveat — when you should bill everything

  • If your attendance occurs outside ICU (e.g. ED, OT, wards), and:
    • The patient is not admitted to ICU (e.g. transferred elsewhere), or
    • The patient is admitted but dies before morning handover,

  • 👉 Then:
    • The on call overnight intensivist should claim all applicable items
    • The incoming intensivist should not claim any items

⚠️ Key compliance points for overnight admission billing

  • Only one intensivist per calendar day can claim ICU daily items.
  • There are no “after-hours” or “callback” ICU billing items — these are built into the daily rate.
  • Emergency attendance items (160–164) require:
    • Imminent danger of death, and
    • Attendance in addition to, not instead of, the primary intensivist.

🧩 Practical takeaway

  • ⚠️ Midnight changes the billing day — not the clinical responsibility.
  • Align billing with calendar-day rules, not roster timing, and ensure clear team agreement to avoid duplicate or rejected claims.
