Excludes1 — never code together — inherited from S91
The conditions below can never be reported together with S91.3 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- open fracture of ankle, foot and toes (S92.-with 7th character B)
- traumatic amputation of ankle and foot (S98.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S91.3 to fully describe the condition. S91.3 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S91.3, but a patient may have both at the same time. When documentation supports it, S91.3 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S90-S99
The conditions below are not part of S91.3, but a patient may have both at the same time. When documentation supports it, S91.3 and the excluded code may both be reported.
Code also — inherited from S91
Two codes may be needed to describe the condition fully. Whether S91.3 is sequenced first depends on the reason for the encounter.
- any associated wound infection
