N99 vs T86
N99 (Intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified) compared with T86 (Complications of transplanted organs and tissue), 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. T86 carries an Excludes2 note covering N99: “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.
