Accurate coding can thus make a large contribution to the amount of funding given to a condition - in fact the funding can depend on the coding so if coding is inaccurate or unrepresentative it can have a severe effect on the money available to treat a particular condition - perhaps even the efficacy of the treatment itself especially for conditions where the cost of the drugs used to treat is high.
The value of accurate, consistent coding crossed national boundaries as they enable like to be compared to like between countries, so there is extensive effort expended to provide clear codes for use by all countries and these are maintained by the World Health Organisation (WHO) in a set of codes referred to as International Classification of Diseases (ICD).
Aspergillosis is a disease that often requires highly expensive drugs to treat. Drug costs can run into several tens of thousands for pounds per year per person, so it is vital that coding is clear, comprehensive and accurate. Unfortunately this does not seem to be the case as yet. A search of ICD codes for aspergillosis reveals a small set of codes:
B44.0 Invasive pulmonary aspergillosis
B44.1 Other pulmonary aspergillosis
B44.2 Tonsillar aspergillosis
B44.7 Disseminated aspergillosis
- Incl.: Generalized aspergillosis
