Pain due to cardiac prosth dev/grft, initial encounter

This code signifies pain experienced by a patient that is directly attributable to the presence of an artificial cardiac device, implant, or graft. This pain is considered an adverse effect or complication of the prosthetic material itself, rather than a primary cardiac condition.

Apply this code when a patient presents with new onset or worsening pain that is clearly linked to a previously implanted cardiac device, such as a pacemaker, defibrillator, artificial heart valve, or coronary artery bypass graft. This code is appropriate for the initial evaluation and treatment of such pain.

• Always sequence this code as a secondary diagnosis, following the code for the underlying pain symptom (e.g., R07.4 for chest pain).
• Ensure documentation explicitly states the pain is "due to" or "associated with" the cardiac prosthetic.
• The "A" at the end indicates an initial encounter for this specific complication; subsequent encounters would use the appropriate subsequent or sequela character.
