All therapies prescribed during pregnancy should be recorded. Therefore, more than one code can be recorded when reporting this data element. Each therapy should be recorded once only.

CODE 9   Not stated/inadequately described

To be recorded by data entry personnel (state/territory health authority) if the data field is left blank or is inadequately completed in the primary data collection.

Jurisdictions that record perinatal data using the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM) should apply the following codes, noting that the ICD-10-AM uses a hierarchical coding system for therapy type, and therefore not all types of therapy will necessarily be recorded:

Code 1 (Insulin) is equivalent in the ICD-10-AM to a code in the range O24.1–O24.9 used in conjunction with the fifth character '2' (insulin treated). Note that where a female has Type 1 diabetes, there is no equivalent fifth character applied to the ICD-10-AM code because Type 1 diabetes is always insulin-treated.

Code 2 (Oral hypoglycaemic) is equivalent in the ICD-10-AM to a code in the range O24.1–O24.9 used in conjunction with the fifth character '3' (oral hypoglycaemic therapy).

Code 3 (Diet and exercise) is equivalent in the ICD-10-AM to a code in the range O24.1–O24.9 used in conjunction with the fifth character '4' (other; diet; exercise; lifestyle management).

For example, for a female who has pre-existing Type 2 diabetes mellitus and uses oral hypoglycaemic therapy and insulin, this would be coded in the ICD-10-AM as O24.12 and would be reported against this data element using Code 1.
