Stress fracture, right humerus, sequela

This code signifies a stress fracture of the right humerus that is no longer in the acute phase of treatment but is still causing ongoing problems or complications. This could include chronic pain, limited range of motion, nonunion, malunion, or other long-term effects resulting from the original stress fracture.

Apply this code when documentation clearly indicates that a patient is presenting for treatment of a residual condition or complication directly attributable to a previously sustained stress fracture of the right humerus. The medical record should specify "sequela," "late effect," or describe a chronic issue stemming from the fracture.

• Ensure the documentation explicitly states "sequela" or describes a chronic condition resulting from the stress fracture, not an acute or healing fracture.
• Do not use this code for an initial encounter or subsequent encounter for an active stress fracture; those require codes from the M84.321- series without the "S" seventh character.
• Always sequence this code after the primary diagnosis for the specific sequela being treated (e.g., chronic pain, nonunion).
