Strain intrns musc/fasc/tend l mid fngr at wrs/hnd lv, sqla

This code signifies a chronic or residual strain affecting the intrinsic muscles, fascia, or tendons of the left middle finger, specifically at the wrist and hand level. This indicates a prior injury to these structures that has resulted in ongoing symptoms or complications.

Apply this code when documenting a patient presenting with persistent pain, weakness, or limited range of motion in the left middle finger due to a previously sustained strain of the intrinsic hand muscles or tendons. This is appropriate for follow-up encounters addressing long-term effects of such an injury.

• Ensure documentation clearly specifies the left middle finger and the intrinsic structures involved.
• Verify that the "S" seventh character for sequela is appropriate, indicating a late effect or complication of a previous injury.
• Differentiate from acute strains, which would use a different seventh character.
