Collection and Usage Attributes
Guide for Use
The order of codes should be determined using the following hierarchy:
- Procedure performed for treatment of the principal diagnosis
- Procedure performed for the treatment of an additional diagnosis
- Diagnostic/exploratory procedure related to the principal diagnosis
- Diagnostic/exploratory procedure related to an additional diagnosis for the episode of care.
Verification Rules
Must be a valid ACHI 10th edition code.
ACHI codes are validated against a number of national and state edits (e.g. age, sex, combination, etc) to improve coding quality.
Collection Methods
Record and code all procedures undertaken during the episode of admitted patient care in accordance with the Australian Coding Standards (refer to ACS 0016 General procedure guidelines, ACS 0042 Procedures normally not coded, ACS 0029 Coding of contracted procedures, ACS 0049 Disease codes that must never be assigned). Procedures are derived from and must be substantiated by clinical documentation.

It is possible to have duplicate codes in this section, for example, bilateral cataract extraction requires two codes to represent the bilateral aspect of the procedure. Please refer to ACS 0020 Bilateral/Multiple Procedures for further information.

All significant procedures undertaken from the time of admission to the time of separation should be coded. Procedures performed in the hospital emergency department, or elsewhere, that precede the admission time should not be coded in the admitted patient episode. Significant procedures include diagnostic and therapeutic procedures. Also include any procedures that were performed under contract with another contracted hospital, health authority or private health provider (non-hospital) and use the contract flag to identify whether they were performed on an admitted or non-admitted basis.

Queensland Hospital Admitted Patient Data Collection (QHAPDC):
Punctuation is excluded in QHAPDC.
This metadata item gives an indication of the extent to which specialised resources, for example, human resources, theatres and equipment, are used. It also provides an estimate of the numbers of surgical operations performed and the extent to which particular procedures are used to resolve medical problems. It is used for classification of episodes of acute care for admitted patients into Australian Refined Diagnosis Related Groups (AR-DRGs).
The Independent Hospital Pricing Authority (IHPA) advises the National Health Information Standards and Statistics Committee of relevant changes to the ACHI.  
AR-DRG Version 9.0 is for use with ICD-10-AM/ACHI 10th edition codes from 1 July 2017.
