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
These injuries affect nerves at the ankle and foot.
The subdivisions distinguish the lateral plantar nerve S94.0, medial plantar nerve S94.1, deep peroneal nerve S94.2, and cutaneous sensory nerve S94.3. Separate subdivisions identify other nerves S94.8 or an unspecified nerve S94.9. Most subdivisions then distinguish the right leg, left leg, or unspecified leg. A seventh character identifies an initial encounter, subsequent encounter, or sequela, meaning a lasting effect.
