Selectivity Not Documented
Operative notes naming the procedure without describing the vessels the catheter traversed.
The fixRecord the access site and each vessel entered, in order, for every case.
Catheter selectivity coded from how far you actually went
Endovascular payment depends on how selectively the catheter was placed, and that detail lives only in your operative note. A catheter advanced into a third-order branch pays substantially more than one that stopped at the aorta, but only if the report describes the path. We code from the vessel sequence, not the procedure name.
Vascular surgery medical billing covers arterial and venous disease treatment. It includes endovascular intervention, open bypass and repair, dialysis access creation and maintenance, varicose vein treatment, and non-invasive vascular testing.
Endovascular work is coded by selectivity. Payment reflects how far the catheter travelled from the point of entry, described in orders of branching. A first-order placement is not the same service as a third-order placement, and the difference is significant.
That information exists only in the operative report. When the note names the procedure without describing the vessels traversed, the coder has to assume the least selective option, and the practice loses the value of work that was genuinely performed.
The payment is determined by anatomy the operative note either records or does not.
Payment rises with how far the catheter was advanced through branching vessels from the access point.
Catheter placement up to a defined point is bundled into the intervention, so separate lines create edits.
Dialysis access maintenance follows its own rules distinct from general arterial intervention.
Varicose vein procedures usually require documented conservative therapy and specific imaging findings.
Nearly all of them trace back to the operative report.

Vessel by vessel, following the catheter path.
Elective procedures are approved with imaging and conservative therapy documented before scheduling.
Coders follow the operative report from access site through every vessel entered to establish selectivity.
Each intervention is checked for what it already includes before any placement or imaging line is added.
Dialysis access procedures are coded from operative detail under their own distinct rules.
Open repair cases have their global window recorded so post-operative returns are handled correctly.
Denials are appealed with the operative report attached, and revenue reported by procedure type.

Note: This is general education on how vascular surgery coding is organised. Code sets and payer policies change often. Always check the current code set and the payer's active policy for the date of service.
We bill inside the system your practice already uses.
Answers for vascular surgeons and endovascular teams.
Because it sets the payment. Advancing a catheter through successive branch vessels is more work than stopping at the main trunk, and the codes reflect that. When the operative note does not describe the path, the coder must assume the least selective option. Recording the access site and each vessel entered captures value you already earned.
The entry point, each vessel the catheter passed into in order, the vessels treated, and the technique used. This reads as anatomical narrative rather than a procedure list. Surgeons who dictate the path naturally get coded accurately. Those who dictate only the procedure name lose value on nearly every endovascular case they perform.
Only when the intervention does not already include it. Many revascularisation codes bundle catheter placement up to the treated vessel, so adding a separate line triggers a correct coding edit. Where the catheter travelled beyond what the intervention covers, additional billing may genuinely apply. We check what each code includes before adding any placement line.
Usually documented conservative therapy, most often a compression trial of a specified duration, plus ultrasound findings confirming venous reflux. Requests lacking either element are routinely denied as cosmetic. Because these procedures are commonly performed in a series, an early denial can stall an entire treatment plan. We assemble both elements before anything is scheduled.
From the operative detail, under their own rules, which differ from general arterial intervention. Access maintenance involves specific interventions performed on a defined circuit, and coding them generically loses real value each time. These cases recur frequently for the same dialysis patients, so a coding habit that undervalues them compounds very quickly across a year.
It depends on the intervention code, since many now include the imaging component. Where it is genuinely separate and your team performed it, it should be billed. Omitting it out of caution loses value, and adding it where bundled creates edits. We check the specific code rather than applying a general rule.
By recording the global window with the case so reception sees it when the patient returns. Routine follow-up is included in the surgical fee, and billing it separately gets recouped. Complications and unrelated care remain billable with the right modifier. Making the window visible prevents the error rather than appealing it later.
Yes, and they are frequently underbilled. Duplex and physiologic studies performed in your laboratory carry their own value, and whether you bill globally or only the interpretation depends on equipment ownership. Studies also need a documented clinical indication. We configure the component rule per location and check indications before submission.
Multiple procedure reductions applied more aggressively than your contract terms allow, particularly on multi-vessel cases. The difference disappears quietly into contractual adjustments whenever payments are posted in bulk rather than line by line. Posting against loaded contract rates exposes it. Given the value of vascular procedures, these variances are well worth pursuing individually.
Changing how operative notes describe the catheter path. Most practices lose selectivity value on a large share of endovascular cases purely because the anatomy was not dictated. A short conversation with your surgeons about describing the route, plus coding from that detail, usually produces a measurable revenue change within one cycle.
We review a month of your endovascular operative notes against billed codes and show you where catheter path detail is costing you.
