About ICD-9-CM 770.2
770.2 is an ICD-9-CM diagnosis code for interstitial emphysema and related conditions. 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 5 ICD-10-CM codes, such as P25.0 (Interstitial emphysema originating in the perinatal period), P25.1 (Pneumothorax originating in the perinatal period) and P25.2 (Pneumomediastinum originating in the perinatal period). All of these are approximate matches, so review the record to pick the right one.
