Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Injury of muscle and tendon at ankle and foot level (S96). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to S96: its own notes plus those printed at block S90-S99 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

On S96 itself
  • injury of Achilles tendon (S86.0-)
  • sprain of joints and ligaments of ankle and foot (S93.-)
From Block S90-S99 Injuries to the ankle and foot applies to 3,324 codes
  • burns and corrosions (T20-T32)
  • fracture of ankle and malleolus (S82.-)
  • frostbite (T33-T34)
  • insect bite or sting, venomous (T63.4)
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

  • any associated open wound (S91.-)

Notes

General instructions on how these codes are used.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category S96
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

Excludes2 2

These codes carry an Excludes2 note naming S96: its condition is not part of those codes, and both may be reported when the patient has both.

  • S86 Injury of muscle, fascia and tendon at lower leg level
    injury of muscle, fascia and tendon at ankle (S96.-)
  • S93 Dislocation and sprain of joints and ligaments at ankle, foot and toe level
