Bulk Bill Claim — Pathology

Submit a bulk bill claim for **pathology** services. Use `serviceTypeCode: P`. A claim may contain up to **80 medical events**, each with up to **14 services**. `medicalEventDate` must not be more than **1 year before submission**. ## 📑 Referral requirement Each medical event must satisfy **one** of the following — otherwise Medicare rejects the claim: - `referral` is supplied with `typeCode: P`, **or** - `referralOverrideCode` is set to `N` (not required), **or** - `selfDeemedCode` is set to `SD` on at least one service (`SS` is **not** permitted for pathology). ## 📑 In-hospital pathology Set `hospitalInd: Y` and supply `facilityId` when the service was rendered in hospital. Omit both for out-of-hospital pathology. ## 📑 Error codes Validation and business-rule failures return **`400`** with `serviceMessage[].code` populated by Medicare. Use the [Services Australia lookup tool](https://www.servicesaustralia.gov.au/look-up-medicare-reason-code) to map each code to a human-readable description.
