E851Accidental poisoning by barbiturates
- Legacy / Not Valid for Submission
- Retired October 1, 2015
- External Cause (E Code)
E851 is a legacy ICD-9-CM external cause code (E code) that described accidental poisoning by barbiturates. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. CMS assigns no direct ICD-10-CM equivalent for this code (a No Map flag in the General Equivalence Mappings), so the closest current code must be chosen from the clinical documentation.

Questions About E851
Is E851 (accidental poisoning by barbiturates) still a valid code?
No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes.
Why does E851 have no ICD-10 equivalent?
CMS marks this code with a No Map flag in the General Equivalence Mappings: no single ICD-10-CM code corresponds to accidental poisoning by barbiturates. To code the same situation today, choose the closest current code from the clinical documentation.
What did E851 mean?
In the final ICD-9-CM release, this code described accidental poisoning by barbiturates. It sat in block E851 Accidental-poisoning by barbiturates under External causes of injury (V).
