Inj intrinsic musc/fasc/tend r thm at wrs/hnd lv, sequela

This code signifies a long-term complication or residual effect stemming from a previous injury to the intrinsic muscles, fascia, or tendons of the right thumb, specifically at the wrist or hand level. This could include persistent pain, weakness, stiffness, or deformity that remains after the initial injury has healed.

Apply this code when documenting a patient presenting with a current condition directly attributable to an old injury of the specified right thumb structures. This is appropriate for follow-up visits addressing chronic issues, or when a new problem arises as a direct consequence of the past trauma. Do not use for acute injuries.

• Always link this sequela code to an external cause code (V, W, X, Y) if the original injury's cause is known and relevant.
• Ensure documentation clearly states the current condition is a residual effect of a previous injury, not an acute one.
• Consider additional codes for specific symptoms or functional impairments if they are not fully captured by the sequela code.
