S31 vs S38.3
S31 (Open wound of abdomen, lower back, pelvis and external genitals) compared with S38.3 (Transection (partial) of abdomen), 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. S31 carries an Excludes1 note covering S38.3: “traumatic amputation of part of abdomen, lower back and pelvis (S38.2-, S38.3)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
