G90.5 vs M89.0
G90.5 (Complex regional pain syndrome I (CRPS I)) compared with M89.0 (Algoneurodystrophy), 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. M89.0 carries an Excludes1 note covering G90.5: “reflex sympathetic dystrophy (G90.5-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
