Validation of International Classification of Disease Ninth Revision codes for atopic dermatitis.
This study sought to validate the use of ICD-9-CM codes for identifying atopic dermatitis. It found that in the outpatient setting, the ICD-9-CM codes 691.8 and 692.9 alone have poor positive predictive value (PPV). Incorporation of diagnoses of asthma, hay fever, and food allergy improves PPV and specificity. In the inpatient setting, a primary discharge diagnosis of 691.8 had excellent PPV.
