ICD-10 Code I97.3 – Postprocedural hypertension (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.3 – Postprocedural hypertension
What it is
I97.3 identifies hypertension that develops after a procedure or operation. Use it when the elevated blood pressure is documented as a postprocedural complication rather than a preexisting condition.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record notes new or worsened hypertension occurring after surgery or another invasive procedure, with the provider linking the blood pressure change to the procedure.
When to use this code
Use I97.3 when the clinician clearly documents postprocedural hypertension as a complication of the procedure. It is appropriate when the hypertension is not simply incidental and is specifically tied to the postoperative or postprocedure period. Check documentation for the causal relationship and timing.
Do not use for
Do not use this code for chronic hypertension present before the procedure or for elevated blood pressure without a documented postprocedural cause. If the record does not support a procedural complication, check documentation and code the confirmed condition instead.
Coding tip
Assign I97.3 only when the provider clearly documents the hypertension as postprocedural and links it to the procedure.
