Proc/trtmt not carried out because of contraindication

This code signifies that a planned medical procedure or treatment was not performed due to a documented medical reason that made the intervention unsafe or inappropriate for the patient. This contraindication is distinct from patient refusal or external factors.

Apply this code when a physician determines a patient has a pre-existing condition, allergy, or other medical factor that makes a specific treatment or procedure too risky or ineffective. Examples include a patient with severe cardiac disease being deemed unsuitable for elective surgery, or a known allergy preventing the use of a particular medication.

• Always sequence this code as a secondary diagnosis, following the primary reason for the planned procedure or treatment.
• Ensure the medical record clearly documents the specific contraindication that prevented the intervention.
• Do not use this code if the procedure was not carried out due to patient refusal (use Z53.2x) or external system reasons (use Z53.8).
