Proc/trtmt not carried out due to patient smoking

This code indicates that a planned medical procedure or treatment was not performed because the patient's active smoking status presented a contraindication or significantly increased risk. It signifies a direct causal link between the patient's tobacco use and the decision to defer or cancel the intervention.

This code is appropriate when a physician documents that a surgical procedure, diagnostic test requiring specific patient preparation, or therapeutic intervention was withheld due to the patient's current smoking. Examples include postponing elective surgery until smoking cessation, or declining a procedure due to unmanageable risks exacerbated by nicotine use.

• Always ensure physician documentation explicitly states that smoking was the reason for not carrying out the procedure or treatment.
• Do not use this code if the procedure was merely delayed for other reasons, even if the patient is a smoker.
• This code is for reporting the reason a procedure was not performed, not for documenting smoking itself (which would use a Z72.0 code).
