Injury of nerves at ankle and foot level (S94) ICD-10-CM
The S94 code range covers injury of nerves at ankle and foot level with 80 ICD-10-CM diagnosis codes. 54 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- any associated open wound S91
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to each code from category S94
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela

About the S94 Code Range
ICD-10 codes starting with S94 are used specifically to classify injuries to nerves at the ankle and foot level. These codes allow healthcare providers to document nerve trauma involving particular nerves in this region, such as the lateral plantar, medial plantar, deep peroneal, and cutaneous sensory nerves, as well as other or unspecified nerves.
These codes cover a variety of injury scenarios, including initial encounters, subsequent care, and complications or sequelae, with precise designations for right, left, or unspecified leg involvement. For instance, the ICD-10 code for lateral plantar nerve injury includes commonly used synonyms like "Lateral plantar neuropathy," helping to clarify coding choices. Similarly, injuries affecting the cutaneous sensory nerve may appear as "Injury of cutaneous sensory nerve of lower limb." This granularity supports accurate reporting for conditions ranging from nerve lacerations to neuropathies, facilitating proper treatment planning and billing. Using these codes helps medical coders align clinical documentation with the exact nerve injured and the stage of care to ensure precise communication about nerve injuries at the ankle and foot.
