T52.812S vs T53
T52.812S (Toxic effect of alkenes, intentional self-harm, sequela) compared with T53 (Toxic effect of halogen derivatives of aliphatic and aromatic hydrocarbons), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. T52.812S carries an Excludes1 note covering T53: “halogen derivatives of aliphatic and aromatic hydrocarbons (T53.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
