External constriction of right back wall of thorax, sequela

This code signifies a long-term or late effect resulting from an external force that caused a narrowing or compression of the right posterior chest wall. This constriction can impact underlying structures and may manifest as chronic pain, respiratory compromise, or functional limitations. It indicates that the initial injury has resolved, but its lasting consequences are still present.

Use this code when documenting a patient presenting with ongoing symptoms directly attributable to a past external constriction injury to the right back of the thorax. This applies to situations where the acute phase of the injury has passed, and the current encounter is for managing the residual effects. Examples include chronic pain from scar tissue, persistent rib deformity, or nerve impingement due to the previous constriction.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, respiratory dysfunction) if applicable.
• Ensure documentation clearly links the current condition to a past external constriction injury of the right back wall of the thorax.
• Do not use for acute or initial injury encounters; this code is exclusively for sequelae.
