This service is for the removal of a cannula or A.V. shunt. It is listed as a Diagnostic and Therapeutic Procedure on page . This procedure has an anaesthesia base unit value of 7.

When to Use

Use R843 specifically for the surgical removal of a permanent A.V. shunt or a long-term vascular access cannula.
Select R843 when the procedure is performed as a distinct surgical intervention, rather than the routine discontinuation of a temporary peripheral IV line.

Common Pitfalls

Do not bill R843 for the simple removal of a temporary peripheral intravenous catheter, as this is considered part of the general care and is not a surgical procedure.
Avoid billing R843 in conjunction with more comprehensive vascular access procedures (e.g., R848) if the removal is an integral part of the primary surgical approach, as this may trigger a 'duplicate service' or 'included in another procedure' rejection.

Billing Tips

Ensure the operative report clearly describes the surgical nature of the removal, especially if the shunt was deeply embedded or required formal closure, to justify the surgical fee over a minor procedure code.
Since R843 has an anaesthesia base unit of 7, ensure that if an anaesthesiologist is involved, the base units are correctly calculated based on this value to avoid discrepancies in the anaesthesia claim.
