T20 vs T85.630
T20 (Burn and corrosion of head, face, and neck) compared with T85.630 (Leakage of cranial or spinal infusion catheter), 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. T85.630 carries an Excludes2 note covering T20: “burns and corrosions from local applications and irradiation (T20-T32)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
