Sprain of interphalangeal joint of l idx fngr, sequela

This code signifies a chronic or late effect of a sprain affecting the joint between the phalanges of the left index finger. This could include persistent pain, stiffness, instability, or other long-term complications arising from an initial sprain injury that has since healed.

Utilize this code when documenting a patient presenting with ongoing symptoms directly attributable to a past sprain of the left index finger's interphalangeal joint. This is appropriate for follow-up visits addressing residual issues, such as chronic pain or limited range of motion, long after the initial acute injury phase has passed.

• Always assign this "S" (sequela) code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current condition to a previous interphalangeal joint sprain of the left index finger.
• Verify the laterality (left) and specific finger (index) are accurately reflected in the medical record.
