7               Kind of injury, disease or death to which this Statement of Principles relates
(1)          This Statement of Principles is about hypersensitivity pneumonitis and death from hypersensitivity pneumonitis.
Meaning of hypersensitivity pneumonitis
(2)          For the purposes of this Statement of Principles, hypersensitivity pneumonitis:
(a)          means a non-infectious, immunological inflammation of the lung parenchyma secondary to inhalation, by a sensitised subject, of any one of a variety of external antigens; and
(b)          includes acute, subacute and chronic hypersensitivity pneumonitis; and
(c)          excludes fibrosing interstitial lung disease, bronchiolitis obliterans organising pneumonia, and lung inflammation resulting from antigen exposure by means other than inhalation, such as ingested drugs and acute anaphylaxis.
Note 1: Hypersensitivity pneumonitis is also known as extrinsic allergic alveolitis.
            Note 2: The inflammation of the lung parenchyma mainly involves the alveoli, terminal bronchioles and interstitium.  The inflammation often organises into granulomas and may progress to fibrosis in chronic cases.
(3)          While hypersensitivity pneumonitis attracts ICD‑10‑AM code J67, in applying this Statement of Principles the meaning of hypersensitivity pneumonitis is that given in subsection (2).
(4)          For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.
Death from hypersensitivity pneumonitis
(5)          For the purposes of this Statement of Principles, hypersensitivity pneumonitis, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's hypersensitivity pneumonitis.
Note: terminal event is defined in the Schedule 1 – Dictionary.
