G89.2 vs G90.5
G89.2 (Chronic pain, not elsewhere classified) compared with G90.5 (Complex regional pain syndrome I (CRPS I)), 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. G89.2 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).
