Other chronic postprocedural pain

This code signifies persistent, long-term pain that develops after a surgical or other medical procedure, and is not classified as post-thoracotomy, post-mastectomy, or phantom limb pain. It represents a chronic pain state directly attributable to the intervention, lasting beyond the expected healing period.

Use this code for patients experiencing chronic pain following a procedure, where the pain is not specifically categorized elsewhere. Documentation should clearly link the chronic pain to a previous surgical or medical intervention and rule out other causes. This code is appropriate when the pain has persisted for at least three months post-procedure.

• Always sequence this code after the code for the underlying chronic pain condition, if applicable, or as the primary diagnosis if the postprocedural pain is the sole reason for the encounter.
• Ensure documentation specifies the procedure that led to the chronic pain and the duration of the pain.
• Distinguish carefully from acute postprocedural pain (e.g., T81.84-) or other specific chronic postprocedural pain codes (e.g., G89.21, G89.22, G89.23).
