Unspecified sprain of left thumb, sequela

This code signifies a long-term consequence or late effect of an unspecified sprain affecting the left thumb. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past sprain.

Apply this code when documenting a patient presenting with chronic pain, stiffness, limited range of motion, or other persistent issues in the left thumb that are clearly linked to a previously sustained, but now healed, sprain. This is appropriate when the acute phase of the injury has passed and the current encounter addresses these lasting effects.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly states the link between the current condition and a past left thumb sprain.
• Avoid using this code for acute or subacute sprains; those require codes from the initial encounter or subsequent encounter categories.
