Strain extn musc/fasc/tend l rng fngr at wrs/hnd lv, sequela

This code signifies a past injury to the extensor muscle, fascia, or tendon of the left ring finger, specifically at the wrist or hand level, that is now causing a residual condition or complication. This could include chronic pain, weakness, limited range of motion, or other long-term effects resulting from the original strain.

Apply this code when documenting a patient presenting with a current problem directly attributable to a previous strain of the extensor structures of the left ring finger. This is appropriate for follow-up visits addressing ongoing issues from an old injury, such as persistent stiffness or chronic discomfort.

• Always use a seventh character "S" for sequela when the current condition is a residual effect of a past injury.
• Ensure documentation clearly links the current symptoms to the previous extensor strain of the left ring finger.
• Do not use this code for acute injuries; refer to the appropriate acute strain codes for initial encounters.
