Answer: Technically, you could report the attempted placement--but many coders do not because the service is not enough to justify a separate claim.
If you do report the service, submit 36620 (Arterial catheterization or cannulation for sampling, monitoring or transfusion [separate procedure]; percutaneous) or 93503 (Insertion and placement of flow directed catheter [e.g., Swan-Ganz] for monitoring purposes) and append modifier 53 (Discontinued procedure).
Include documentation so the carrier knows your physician did not complete the procedure.
