M48.50XD vs S12
M48.50XD (Collapsed vertebra, not elsewhere classified, site unspecified, subsequent encounter for fracture with routine healing) compared with S12 (Fracture of cervical vertebra and other parts of neck), 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. M48.50XD carries an Excludes1 note covering S12: “traumatic fracture of vertebra (S12.-, S22.-, S32.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
