About ICD-9-CM 307.42
307.42 is an ICD-9-CM diagnosis code for persistent disorder of initiating or maintaining sleep. 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 F51.01 (Primary insomnia), F51.03 (Paradoxical insomnia) and F51.09 (Other insomnia not due to a substance or known physiological condition). All of these are approximate matches, so review the record to pick the right one.
