Often patients present with Iron Overload for Venesection. There is currently no essential modifier for 'Iron' under the lead term 'Overload'.

Can you please confirm the correct code to assign for documentation of Iron Overload is E83.1 Disorders of iron metabolism? Following the lead term:

Disorder
- Metabolism
- - Iron E83.1

VICC advises that in the absence of a sub term for iron under lead term Overload, to follow the Index entry Disease/iron metabolism or storage to assign E83.1 Disorders of iron metabolism. This is supported by Example 32 in the Conventions used in the Tabular list of diseases which says, ‘the main term Polyp in the index does not include a subterm of 'oesophagus'. To find the correct code assignment, next search the index for Disease/oesophagus/specified, which indicates code K22.8 Other specified diseases of oesophagus’.
