Unspecified injury of deep palmar arch of left hand, sequela

This code signifies a past injury to the deep palmar arch of the left hand, where the specific nature of the injury is not documented. It indicates that the patient is currently experiencing a residual effect or complication from this prior, unspecified trauma. This could include ongoing pain, stiffness, or functional limitation.

Apply this code when a patient presents with a current problem directly attributable to an old, unspecified injury of the deep palmar arch of the left hand. This is appropriate for follow-up visits where the initial acute injury has resolved, but the patient continues to experience sequelae. Examples include chronic pain after a past crush injury or persistent weakness following a previous sprain.

• Always use in conjunction with a code describing the specific sequela (e.g., chronic pain, scar formation, muscle weakness).
• Ensure documentation clearly links the current condition to a past injury of the deep palmar arch of the left hand.
• Verify that the injury type was truly unspecified in the initial encounter documentation to justify using the ".30" subcategory.
