Contusion of left breast, sequela

This code indicates a bruise or contusion of the left breast, where the injury itself has healed, but the patient is experiencing a residual effect or complication from that past injury. These sequelae could include chronic pain, scarring, tissue deformity, or other long-term issues directly attributable to the original contusion.

This code is appropriate when a patient presents for treatment of a current condition that is a direct consequence of a contusion to the left breast that occurred in the past. It should be used when the acute phase of the original injury has passed, and the current encounter addresses the lasting effects. For example, a patient seeking treatment for persistent pain or a palpable lump resulting from an old breast contusion.

• Always assign an additional code(s) to describe the specific nature of the sequela (e.g., chronic pain, scar, deformity).
• Do not use this code for an acute contusion; use the appropriate acute injury code.
• The "S" in the 7th character indicates sequela and is crucial for proper code assignment.
