External constrict of middle front wall of thorax, sequela

This code signifies a long-term or residual effect resulting from an external constriction injury to the middle front wall of the thorax. This could involve chronic pain, scarring, nerve damage, or impaired function in the sternal or parasternal region due to a past constrictive force.

Apply this code when documenting a patient presenting with ongoing issues directly attributable to a previous external constriction injury to the middle anterior chest. This is appropriate for follow-up encounters after the initial injury has healed, but its lasting impact persists.

• Always use in conjunction with an external cause code (V00-Y99) to specify the cause of the original constriction.
• Ensure documentation clearly links the current sequela to the past external constriction injury.
• Do not use for acute or initial injury encounters; this code is specifically for residual conditions.
