How is S91.101 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to S91.101. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Wound, open › toe › great › right

Excludes1 — never code together — inherited from S91

The conditions below can never be reported together with S91.101 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 S91.101 to fully describe the condition. S91.101 is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Excludes2 — not included here — inherited from Chapter 19

  • birth trauma (P10-P15)
  • obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from S90-S99
