Is S91.106D billable?

Yes, but S91.106D is an unspecified code. S91.106D is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S91.106D is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting S91.106D — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from S91

The conditions below can never be reported together with S91.106D 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 S91.106D to fully describe the condition. S91.106D 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 S91.106D, but a patient may have both at the same time. When documentation supports it, S91.106D and the excluded code may both be reported.

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

Excludes2 — not included here — inherited from S90-S99

The conditions below are not part of S91.106D, but a patient may have both at the same time. When documentation supports it, S91.106D and the excluded code may both be reported.

  • burns and corrosions (T20-T32)
  • fracture of ankle and malleolus (S82.-)
  • frostbite (T33-T34)
  • insect bite or sting, venomous (T63.4)

Code also — inherited from S91

Two codes may be needed to describe the condition fully. Whether S91.106D is sequenced first depends on the reason for the encounter.

  • any associated wound infection

How long has S91.106D existed?

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
