Postprocedural hypertension

This code signifies elevated blood pressure that develops as a direct consequence of a medical or surgical procedure. It represents a new onset or exacerbation of hypertension directly attributable to the physiological stress, medication effects, or other sequelae of an intervention.

Assign this code when documentation clearly links the onset of hypertension to a recent procedure, and the hypertension is not a pre-existing condition or an unrelated new diagnosis. Supporting documentation should specify the procedure performed and the subsequent development of elevated blood pressure.

• Always sequence this code after the code for the underlying procedure or condition necessitating the procedure, if applicable.
• Distinguish from essential hypertension (I10) or secondary hypertension due to other causes; the procedural link must be explicit.
• Do not use for transient blood pressure fluctuations during or immediately after a procedure that resolve without intervention.
