R09.0 vs T17
R09.0 (Asphyxia and hypoxemia) compared with T17 (Foreign body in respiratory tract), 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. R09.0 carries an Excludes1 note covering T17: “asphyxia due to foreign body in respiratory tract (T17.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
