Inj flexor musc/fasc/tend l little fngr at wrs/hnd lv, sqla

This code signifies a long-term effect or complication resulting from a previous injury to the flexor muscles, fascia, or tendons of the left little finger, specifically within the wrist and hand region. This could include conditions like chronic pain, stiffness, limited range of motion, or nerve damage directly attributable to the initial trauma.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of an old injury to the flexor structures of the left little finger. This is appropriate for follow-up visits addressing persistent issues after the initial acute injury has healed.

• Always link this sequela code to an external cause code (V, W, X, Y codes) if the original injury's cause is known and relevant to the current encounter.
• Ensure documentation clearly states the current condition is a residual effect of a past injury, not an acute injury.
• Do not use this code for acute injuries; instead, use the appropriate acute injury code from the S66.19- series.
