ICD-10 Code I97.19 – Other postprocedural cardiac functional disturbances (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.19 – Other postprocedural cardiac functional disturbances
What it is
I97.19 identifies cardiac functional problems that develop after a procedure and are not classified elsewhere. Use it when documentation states a postprocedural cardiac disturbance, but the exact complication is not more specific.
Clinical signs
Clinical features vary; refer to documentation. Findings may include new or worsening cardiac dysfunction after surgery or another procedure, with the provider linking the change to the intervention.
When to use this code
Use this code when the record clearly describes a cardiac functional disturbance caused by a prior procedure and no more specific ICD-10-CM code applies. It is appropriate for postoperative cardiac dysfunction documented by the provider as a complication. If the note names a different postoperative cardiac issue, code that condition instead.
Do not use for
Do not use I97.19 for routine postoperative monitoring, expected recovery findings, or pre-existing cardiac disease without a documented procedural link. Check documentation if the complication is better described by another postoperative cardiac code.
Coding tip
Assign I97.19 only when the provider explicitly connects the cardiac disturbance to the procedure.
