G89.2 vs G89.4
G89.2 (Chronic pain, not elsewhere classified) compared with G89.4 (Chronic pain syndrome), 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 G89.4: “chronic pain syndrome (G89.4)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
