T65.3X1 vs T65.3X2
T65.3X1 (Toxic effect of nitroderivatives and aminoderivatives of benzene and its homologues, accidental (unintentional)) compared with T65.3X2 (Toxic effect of nitroderivatives and aminoderivatives of benzene and its homologues, intentional self-harm), from the official CMS tabular data. T65.3X1 and T65.3X2 code the same substance (Aniline) with a different intent.
Can these codes be reported together?
Same substance, different intent. T65.3X1 and T65.3X2 code the same substance (Aniline) with a different circumstance of exposure.
From the CMS Table of Drugs and Chemicals: accidental poisoning, intentional self-harm, assault, undetermined intent, adverse effect and underdosing are mutually exclusive columns — only one of them applies to a given encounter.
