This section provides a list of codes used to define mental health-related general practice encounters from the Bettering the Evaluation and Care of Health (BEACH) database (as used in the general practice section) and ‘mental
health-related’ hospital separations from the National Hospital Morbidity Database (as used in the
Ambulatory-equivalent and Admitted patient sections).

BEACH survey of general practice activity data

For the purpose of this report, mental health-related general practice encounters are defined as those encounters where a mental health-related problem was managed. Mental health-related problems are those that are classified in the psychological chapter (that is, the ‘P’ chapter) of the International Classification of Primary Care, 2nd edition (ICPC-2). In the great majority of cases the codes appearing in the diagnosis or problem fields of the BEACH survey form those listed here under the ‘Problems managed’ heading. Occasionally a code more relevant to treatments or referrals has appeared. These cases (accounting for 3% of all mental health-related problems managed in BEACH in 2011–12) are still counted as ‘mental health-related’ general practice encounters for the purpose of the report, in particular the estimates in Table Class Code 1 below.

For treatments and referrals, codes that are classified in the psychological chapter of the ICPC-2 PLUS have been used as these enable greater specificity in coding.

For medications, Anatomical Therapeutic Chemical (ATC) classification codes (WHO 2011) have been used, where the medication falls into one of four groups.

The following table presents a list of the ICPC–2, ICPC–2 PLUS and ATC codes classed as ‘psychological’ for problems managed, treatments, referrals and medications.

National Hospital Morbidity Database data

Data from the National Hospital Morbidity Database (NHMD) is the source for the Ambulatory-equivalent and Admitted patient sections of this online report. The definition of the scope of each section is provided in the section’s introduction or data source. Key elements of these definitions depend on the ICD–10–AM diagnosis codes and the Australian Classification of Health Interventions (ACHI) procedure codes. The codes in-scope are listed below.

During the preparation of Mental health services in Australia 1999–00 (AIHW 2002), attention was given to ensuring that, for data on hospital separations from the NHMD, the definition of a ‘mental health-related diagnosis’ included all codes that were either clinically or statistically relevant to mental health. This definition was revised for Mental health services in Australia 2000–01 (AIHW 2003) to increase the accuracy of the data. More specifically, for the analyses of the 2000–01 National Hospital Morbidity data, a diagnosis was considered clinically relevant to mental health if:

  • it was included as a principal diagnosis defining Australian Refined Diagnosis Related Group Version 4.2 Major Diagnostic Categories (MDC) 19 (Mental diseases and disorders) and 20 (Alcohol/drug use and alcohol/drug induced organic mental disorders), or
  • it appeared to be specific for a mental health-related condition based on expert advice.

A diagnosis was defined as being statistically relevant to mental health if:

  • during 2000–01 there were more than 20 separations with specialised psychiatric care for that principal diagnosis at the 3-character level of ICD-10-AM or more than 10 at the 4-character level, or
  • over 50% of separations with that principal diagnosis included specialised psychiatric care.

This method was developed in consultation with the National Mental Health Working Group Information Strategy Committee (now called the Mental Health Information Strategy Standing Committee) and the Clinical Casemix Committee of Australia.

Certain codes were statistically relevant during 1999–00 but not in 2000–01; these were examined and included if over 50% of total separations over the 2 years included specialised psychiatric care.

For Mental health services in Australia, the same codes used for the analysis of the 2000–01 data have been used to define ‘mental health-related’ hospital separations in the Ambulatory-equivalent and Admitted patient care sections. However, updates have been made to incorporate changes in codes that have occurred as new editions of ICD-10-AM have been released.

The full list of codes used to define mental health-related hospital separations is shown in the following table.
