About ICD-9-CM 748.5
748.5 is an ICD-9-CM diagnosis code for agenesis, hypoplasia, and dysplasia of lung. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as Q33.2 (Sequestration of lung), Q33.3 (Agenesis of lung) and Q33.6 (Congenital hypoplasia and dysplasia of lung). All of these are approximate matches, so review the record to pick the right one.
