ICD-10-CM Coding for Right Anterior Lower Leg Laceration from Dish Injury

For a simple laceration on the right anterior lower leg from a broken dish, cleaned and dressed, use S81.811A (Laceration without foreign body, right lower leg, initial encounter).

Code Structure and Selection

The appropriate ICD-10-CM code follows the standardized structure for traumatic injuries to the lower leg 1:

  • S81.811A breaks down as:
    • S81 = Open wound of knee and lower leg
    • .81 = Laceration without foreign body of lower leg
    • 1 = Right leg (laterality)
    • A = Initial encounter

Key Coding Considerations

Encounter Type Designation:

  • Use the "A" (initial encounter) suffix since you are seeing the patient for the first time for this injury and providing active treatment (cleaning and dressing)
  • Subsequent encounters for the same laceration would use "D" (subsequent encounter)
  • Sequelae/late effects would use "S"

Foreign Body Status: Since you cleaned the area and there is no mention of retained foreign body, the "without foreign body" designation (.811) is appropriate. If glass or ceramic fragments were embedded and not removed, you would instead use S81.821A (laceration with foreign body).

Additional Required Codes

External Cause Code: You must also assign an external cause code to document the mechanism of injury:

  • W25.XXXA (Contact with sharp glass, initial encounter) is the appropriate external cause code for a dish-breaking injury

Place of Occurrence (if documented):

  • Add Y92.0 (home) if the injury occurred at home
  • Or appropriate place code if documented differently

Common Pitfalls to Avoid

  • Do not use unspecified codes when laterality and specifics are known—the right leg location is documented, so use the specific code 2
  • Do not confuse lower leg with ankle/foot—the anterior lower leg is distinct from ankle injuries (S91.xxx codes)
  • Always include the encounter type (A, D, or S)—this is mandatory in ICD-10-CM 1
  • Document whether foreign body is present or absent—this changes the code from .811 to .821

Documentation Requirements

For optimal coding specificity, ensure your documentation includes:

  • Exact anatomical location (anterior lower leg)
  • Laterality (right)
  • Depth/severity if significant
  • Presence or absence of foreign body
  • Mechanism of injury (broken dish/glass)
