Excludes2 — not included here
The conditions below are not part of S13.1, but a patient may have both at the same time. When documentation supports it, S13.1 and the excluded code may both be reported.
- fracture of cervical vertebrae (S12.0-S12.3-)
Code also
Two codes may be needed to describe the condition fully. Whether S13.1 is sequenced first depends on the reason for the encounter.
Use additional code — inherited from Chapter 19
Report an additional code alongside S13.1 to fully describe the condition. S13.1 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)

How long has S13.1 existed?
S13.1 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
