ICD-10 Code I97.1 – Other postprocedural cardiac functional disturbances (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.1 – Other postprocedural cardiac functional disturbances
What it is
I97.1 identifies cardiac functional problems that occur after a procedure and do not fit a more specific postoperative heart complication code. Use it when the record states a postprocedural cardiac disturbance, but the exact type is not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Records may describe new or worsening cardiac dysfunction after surgery or another procedure, with findings that support a postoperative cardiac complication rather than a preexisting condition.
When to use this code
Use I97.1 when the provider documents an other postprocedural cardiac functional disturbance and no more specific code applies. It may fit postoperative notes, discharge summaries, or complication statements tied to a recent procedure. Confirm that the condition is described as procedural and not simply an unrelated heart disorder.
Do not use for
Do not use this code for routine postoperative pain, expected recovery findings, or a clearly specified cardiac complication with its own code. Check documentation if the heart problem is preexisting or if the postoperative relationship is not stated.
Coding tip
Assign I97.1 only when the documentation links the cardiac disturbance to the procedure and no more specific postoperative cardiac code is available.
