Disp fx of middle phalanx of left middle finger, sequela

This code signifies a past fracture of the middle bone in the left middle finger that was out of alignment and is now causing ongoing issues or complications. These sequelae can include chronic pain, stiffness, deformity, nonunion, malunion, or functional limitations resulting from the original injury. The fracture itself has healed, but its lasting effects are still present and require medical attention.

Use this code when documenting a patient presenting with a long-term complication or residual effect directly attributable to a previously sustained and healed displaced fracture of the middle phalanx of the left middle finger. This applies when the acute phase of the fracture treatment is complete, and the current encounter addresses the chronic consequences. Examples include follow-up for persistent pain, limited range of motion, or a visible deformity stemming from the old injury.

• Always assign this code as a secondary diagnosis, with the primary diagnosis reflecting the specific sequela being treated (e.g., M25.542 for pain in left finger).
• Ensure documentation clearly links the current condition to the previous displaced fracture of the left middle finger's middle phalanx.
• Verify that the "S" seventh character is appropriate, indicating a sequela, rather than an initial or subsequent encounter for the acute fracture.
