From the Research

The ICD-10 code for a subungual hematoma of the left great toe is S90.222A for an initial encounter. This code specifically identifies a contusion (hematoma) affecting the nail of the left great toe. If the patient is being seen for subsequent care, the code would change to S90.222D for a follow-up encounter during the healing phase, or S90.222S if the condition has reached the sequela stage (representing complications or conditions that arise as a direct result of the initial injury) 1, 2, 3, 4, 5.

Key Points to Consider

  • Subungual hematomas occur when blood collects under the nail following trauma, typically from direct impact or crushing injuries to the toe.
  • The coding is specific to the left great toe location, which is important for accurate medical documentation and billing purposes.
  • If there are additional injuries or complications present, supplementary codes may be needed to fully capture the patient's condition.

Management and Treatment

The management of subungual hematoma includes trephination or nail removal to relieve pressure and pain, as discussed in the study by 2.

Importance of Accurate Coding

Accurate coding is crucial for proper medical documentation, billing, and insurance purposes. It ensures that patients receive appropriate care and compensation for their injuries.

Additional Considerations

In cases where the subungual hematoma is caused by a more severe injury, such as a crush injury or a fracture, additional codes may be necessary to capture the full extent of the injury 3, 4.
