S09.2 vs S09.31
S09.2 (Traumatic rupture of ear drum) compared with S09.31 (Primary blast injury of ear), 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. S09.2 carries an Excludes1 note covering S09.31: “traumatic rupture of ear drum due to blast injury (S09.31-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
