HCP annual report
The Hospital Casemix Protocol (HCP) 2021-22 Annual Report has been released on the Department of Health and Aged Care website. Data for 2021-22 is preliminary only. For the majority of tables, statistics are presented for the time period 2010-11 to 2021-22. The reports are available in Excel format and contain summarised data collected from private health insurers through HCP1.
Tables include statistics related to Care Type, Completeness, Charge Components, Patient Age Groups, Medical services and Australian Refined - Diagnosis Related Groups (available for 2021-22 only) for privately insured separations in public and private hospitals.
New to this report, the Department has revised its methodology for calculating overall statistics following a review of HCP1 separations without a medical (i.e. MBS) component. These separations were previously included in the analysis however, findings from a review showed it was more appropriate to exclude these separations when calculating overall statistics to avoid understating the medical component contribution to the overall charges, benefits and out-of-pocket amounts. The review found many separations without a medical component contained other information that indicated a medical component was likely to have occurred, such as the separation:
- had a principal or additional MBS item(s) in the HCP1 Episode Record,
- was assigned a diagnosis related group within the surgical partition,
- had 1 or more Australian Classification of Health Intervention codes,
had medical charges and/or benefits data supplied in the HCP1 Episode Record, or
had at least one record in the separation’s corresponding HCP1 Medical Record, albeit with missing data.
The preliminary Hospital Casemix Protocol (HCP) 2021-22 Annual Report includes both the revised and previous methodologies for Table 1.

PHDB Annual report
The Private Hospital Data Bureau (PHDB) 2021-22 Annual Report has been released on the Department of Health and Aged Care website. Data for 2021-22 is preliminary only. For the majority of tables, statistics are presented for the time period 2010-11 to 2021-22. The reports are available in Excel format and contain summarised data collected from private hospitals through PHDB.
Tables include statistics related to Care Type, Completeness, Charge Components, Funding source, Patient Age Groups and Australian Refined - Diagnosis Related Groups (available for 2021-22 only) for private hospital separations.
See the 2021-22 PHDB Annual Report.
To enable greater consistency between HCP and PHDB Annual Report statistics and figures published in the Australian Institute of Health and Welfare’s (AIHW) Australian Hospital Statistics annual reports, the hospital type (i.e. public or private) has been adjusted in a small number of cases. Further information is available in each Annual Report’s Explanatory notes section.
In addition to the methodology change mentioned, further minor adjustments to the methodology used to calculate statistics presented in the HCP and PHDB Annual Reports may result in differences when compared to previously published Annual Reports.
Although improvements have been made, the Department notes there is an ongoing issue in the HCP (hospital to insurer), HCP1 (insurer to Department) and PHDB data involving the supply of non-admitted service data such as those involving patients receiving services as outpatients, or visited by community nurses at home. In particular, these relate to the AR-DRGs (version 9.0): U60Z (Mental Health Treatment W/O ECT, Sameday) and V62B (Alcohol Use and Dependence, Minor Complexity).
As outlined in the relevant data specifications, HCP, HCP1 and PHDB data should only contain admitted patient care episodes. A relatively small number of these additional non-admitted records are currently included in both the HCP and PHDB Annual Reports as there is insufficient information available to enable the Department to exclude them. The Department continues to consult with hospitals, health insurers and software vendors to ensure future data submissions are consistent with the scope of each data collection and contain admitted episodes only.
We also note that the under-reporting of dialysis related separations in HCP1 and PHDB which primarily impacts AR-DRGs (version 9.0): L61Z (Haemodialysis) and L67C (Other Kidney and Urinary Tract Disorders, Minor Complexity) and the over-reporting of rehabilitation separations in HCP1 which primarily impacts AR-DRG (version 9.0): Z60B Rehabilitation, Minor Complexity.
