About ICD-9-CM 513.0
513.0 is an ICD-9-CM diagnosis code for abscess 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 J85.0 (Gangrene and necrosis of lung), J85.1 (Abscess of lung with pneumonia) and J85.2 (Abscess of lung without pneumonia). All of these are approximate matches, so review the record to pick the right one.
