H59 vs T80
H59 (Intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified) compared with T80 (Complications following infusion, transfusion and therapeutic injection), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Can these codes be reported together?
Yes, when both are documented. T80 carries an Excludes2 note covering H59: “intraoperative and postprocedural complications of specified body systems (D78.-, E36.-, E89.-, G97.3-, G97.4, H59.3-, H59.-, H95.2-, H95.3, I97.4-, I97.5, J95.6-, J95.7, K91.6-, L76.-, M96.-, N99.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
