ICD-9-CM diagnosis code (retired)
345.2 — Petit mal status
About ICD-9-CM 345.2
345.2 is an ICD-9-CM diagnosis code for petit mal status. 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 4 ICD-10-CM codes, such as G40.A01 (Absence epileptic syndrome, not intractable, with status epilepticus), G40.A09 (Absence epileptic syndrome, not intractable, without status epilepticus) and G40.A11 (Absence epileptic syndrome, intractable, with status epilepticus). All of these are approximate matches, so review the record to pick the right one.
