Inpatient Billing Guidelines Australia

A practical framework for Australian specialist inpatient billing, from confirming the admitted-patient context through to MBS validation, Medicare/private health claiming, reconciliation and follow-up.

1. Confirm the patient and service setting

Do not assume that every service delivered at a hospital is an inpatient service. Hospital outpatient treatment and admitted private-patient treatment can have different Medicare and private health insurance consequences. Confirm the patient's status and the service setting from reliable records.

2. Work from current MBS information

Use the current MBS item descriptor and relevant explanatory notes. Check item-specific conditions, restrictions, duration or frequency requirements, associated items and co-claiming rules where relevant. Static spreadsheets and old fee lists can become outdated.

3. Validate administrative information

• Patient name and Medicare details.
• Private health insurance details where applicable.
• Date of service and hospital/facility.
• Treating provider and correct provider number/location.
• Referral information where relevant.
• Item number(s) authorised for billing.
• Fee and applicable billing/gap arrangement.

4. Understand the in-hospital benefit structure

For eligible medical services supplied to a private patient in hospital, Medicare generally pays 75% of the MBS fee and private health insurance covers at least 25% of the MBS fee. If the doctor's fee exceeds the MBS fee, an out-of-pocket gap may remain unless an applicable no-gap or known-gap arrangement changes the payment.

5. Check the appropriate claiming pathway

Depending on the claim, provider and insurer, inpatient billing may use ECLIPSE and In-patient Medical Claims. Confirm that provider registration, fund arrangements and required identifiers are in place before expecting a claim to process normally.

6. Do not treat lodgement as the end of billing

A robust workflow tracks assessment, payment, rejection and outstanding claims. Reconcile remittances to the underlying service and investigate discrepancies rather than allowing unpaid items to age unnoticed.

7. Handle rejections systematically

Read the assessment or rejection information first. Recheck patient details, provider/location, item number, service date, referral, fund registration and the relevant MBS conditions. Correct only what is supported by the underlying records and practitioner instructions.

8. Keep evidence and records

Maintain appropriate records supporting the billing workflow and the information supplied for claiming. Billing administration should reflect the clinical service documented and authorised by the treating practitioner.

9. Recheck rules when they change

MBS items, fees, Medicare administrative processes and private insurer arrangements can change. Build periodic official-source checks into the billing process rather than assuming last year's workflow remains current.
