Unsp disp fx of surgical neck of left humerus, sequela

This code describes a long-term complication or residual effect stemming from an unconfirmed displaced fracture of the surgical neck of the left humerus. It indicates that the initial injury has healed, but the patient continues to experience issues directly attributable to that past fracture.

Use this code when documenting a patient presenting with a current condition (e.g., chronic pain, limited range of motion, nonunion, malunion, or deformity) that is a direct consequence of a previously sustained, unspecified displaced fracture of the surgical neck of the left humerus. This code is appropriate when the acute phase of the fracture has passed and the patient is being treated for the sequelae.

• Always assign this "S" (sequela) code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M25.522 for chronic pain in left shoulder).
• Ensure documentation clearly links the current condition to the past fracture of the surgical neck of the left humerus.
• Do not use this code for initial or subsequent encounters for the active fracture treatment; those require codes from the initial or subsequent encounter categories.
