The regions on chromosomes 7 and 12 may coincide with the asthma and atopy loci on the same chromosomes. Polymorphism in the IL1 cluster on chromosome 2 has also been shown to influence the severity of the disease (95, 96).
If patients have COPD and asthma, coders must assign two codes (from category J44 for COPD and category J45 to identify the severity and status of the asthma), according to the ICD-10-CM Official Guidelines for Coding and Reporting.
