T52.893S vs Z77
T52.893S (Toxic effect of other organic solvents, assault, sequela) compared with Z77 (Other contact with and (suspected) exposures hazardous to health), 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. T52.893S carries an Excludes1 note covering Z77: “contact with and (suspected) exposure to toxic substances (Z77.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
