Finding of cocaine in blood

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R78.2 is a billable code used to indicate a diagnosis of finding of cocaine in blood.

Key Diagnostic Point:

The ICD-10 code R78.2 is used to indicate the presence of cocaine in the blood, which is a significant finding in clinical settings. Cocaine is a powerful stimulant that affects the central nervous system and can lead to various acute and chronic health issues. The detection of cocaine in blood samples is often associated with symptoms such as increased heart rate, hypertension, euphoria, and potential psychosis. Clinically, this finding may arise from recreational use, accidental exposure, or as part of a substance abuse disorder. It is crucial for healthcare providers to document the context of the cocaine finding, including the patient's history, presenting symptoms, and any relevant laboratory results. This code is not only important for diagnosis but also for understanding the patient's overall health status and guiding treatment decisions. Accurate documentation is essential to support the diagnosis and to ensure appropriate management of the patient's condition.
