CPT code 92920 – Coronary balloon angioplasty, single major artery

Key takeaways

CPT code 92920 reports balloon angioplasty in one major coronary artery and its branches, and a stent in that artery moves the claim to 92928.

The branch add-on 92921 was deleted on January 1, 2026, so angioplasty in a branch of the same artery is now part of 92920.

A second major artery takes its own primary code, and some payers require a coronary modifier (LC, LD, RC, LM or RI) on each line.

Same-day diagnostic angiography is billable with modifier -59 or XS only when the report documents a separate decision to intervene.

Pabau’s practice software submits PCI claims through Claim.MD, checks eligibility, and tracks claim status and ERA remittances.

CPT code 92920 covers balloon angioplasty in one major artery

CPT code 92920 reports percutaneous transluminal coronary angioplasty in a single major coronary artery and its branches.

The cardiologist opens a narrowed segment with a balloon, and no stent is left behind. The American Medical Association’s CPT code set revised the descriptor for 2026 so that branch work now sits inside the primary code.

Three parts of the descriptor decide whether 92920 fits the case. Check each one against the operative report.

• Percutaneous transluminal: the catheter enters through a peripheral artery, usually radial or femoral, rather than through open surgery.
• Angioplasty: a balloon is inflated at the stenosis to widen the lumen. If a stent is deployed, 92920 no longer applies.
• One major artery and its branches: the code counts arteries, not balloon inflations. Several inflations in the left anterior descending artery and its diagonal still make one 92920.

The 2026 revision changes old habits. The branch add-on 92921 was deleted on January 1, 2026, along with the matching stent and atherectomy add-ons. A claim that still lists 92921 for a 2026 date of service will reject.

Clinically, 92920 appears in PCI for coronary artery disease when balloon dilation alone gives an acceptable result. Most claims pair it with a native-vessel atherosclerosis code such as I25.10, or with an acute coronary syndrome code for emergent cases.

When the balloon only pre-dilates the lesion before a stent, 92928 replaces 92920 for that artery.

What 92920 bundles, and what you can still bill beside it

Several services are paid inside 92920 and cannot be reported on their own. Others are billable next to it when the documentation supports them.

NCCI edit tables change quarterly, so check the current bundling status of intravascular imaging codes before you submit. Reporting a bundled service without a valid modifier is the fastest route to a CO-97 denial.

CPT 92920 sits at the base of the PCI code family

The PCI family runs from balloon-only angioplasty through stenting, atherectomy and chronic total occlusion work. Picking the right code for each artery prevents the most common coding errors.

The grid below works through one artery at a time.

Key rule: 92920 and 92928 are never reported together for the same lesion. When a stent follows balloon pre-dilation, 92928 is correct because it already includes the angioplasty. Use 92920 only when the balloon is the definitive treatment for that artery.

What the cath lab report must show before you bill 92920

A clean claim submission for 92920 depends on what the interventional cardiologist writes in the cath lab report. Check each element below before the claim goes out.

1. Vessel identification: the report names each major artery treated, such as the left main, left anterior descending, circumflex, right coronary or ramus intermedius. “Coronary intervention performed” is not enough.
2. Lesion characteristics: record the pre-procedure stenosis as a percentage of diameter, the lesion length, and any calcification or tortuosity.
3. Approach and access: note the access site, radial or femoral, and the guiding catheter used.
4. Balloon details: list balloon size, inflation pressure and the number of inflations. Multiple inflations in one artery still count as a single 92920.
5. Post-procedure result: record the residual stenosis. If it stays high, the report should say why no stent was placed.
6. No stent deployed: when the case ends with balloon angioplasty alone, the report says so plainly. That line heads off payer requests to justify 92920 over 92928.

Place of service affects payment. Almost all PCI procedures happen in hospital outpatient departments (POS 22) or inpatient settings (POS 21), and 92920 is rarely billed in a non-facility setting.

How a 92920 claim moves from the cath lab to payment

Knowing the path helps you see where a claim stalls. A typical hospital outpatient PCI claim goes through six steps.

1. The cardiologist signs the cath lab report, naming each artery treated and the devices used.
2. The coder assigns a primary code for each artery and adds coronary modifiers where the payer asks for them.
3. The biller confirms eligibility and, for elective cases, attaches the prior authorization number.
4. The claim reaches the payer through a clearinghouse, which checks format and required fields rather than clinical logic.
5. The payer applies NCCI edits and its own policy, then returns an ERA (835) with the payment or a denial code.
6. Your team posts the remittance and works any denial against the operative report.

Modifiers on CPT 92920 depend on the artery and the session

Modifier choice on 92920 drives both underpayment and audit exposure. A missing modifier leaves a line unpaid, while a forced one unbundles work that belongs together. Ask one question every time: does the documentation support the extra service on its own?

On modifier -59 and the X-modifiers: CMS introduced XE, XS, XP and XU as more specific alternatives to -59. XS (separate structure) fits PCI best when the diagnostic study and the intervention involve separate anatomy. Some MACs now prefer XS over -59 for this family, so check your local MAC’s guidance before defaulting to -59.

Medicare pays CPT 92920 on the same RVUs in every setting

Medicare pays CPT 92920 under the Physician Fee Schedule (MPFS), which uses relative value units. For CY 2026, the code carries 11.59 total RVUs in both the facility and non-facility columns.

Pull locality rates from the CMS MPFS lookup tool, because the conversion factor and geographic adjustments set the dollar figure.

For contract talks or budget projections, the FastRVU 2026 RVU lookup tool gives locality-adjusted estimates. Medicare Advantage plans often apply their own fee schedules, so check each remittance against the contract.

Posting electronic remittance advice promptly lets you spot short payments on PCI claims while the appeal window is still open.

Adjunct codes that often share a claim with 92920

PCI claims rarely travel alone. These adjunct codes are the ones coders see most often next to 92920. The AAPC CPT code lookup has the full descriptor for each.

Prior authorization decides whether elective PCI gets paid

Prior authorization rules for CPT 92920 vary by payer and by whether the PCI is elective or emergent. A missed authorization is a preventable denial, so build the check into your prior authorization process at scheduling.

• Traditional Medicare (Parts A and B): does not require prior authorization for most PCI procedures. Emergent and urgent PCI is generally exempt under any payer.
• Medicare Advantage plans: many require prior authorization for elective PCI. Criteria usually include documented stenosis, often 70% or greater, and evidence of ischemia on stress testing or FFR. They also look for failure of, or a contraindication to, guideline-directed medical therapy (GDMT).
• Commercial payers: requirements vary by plan, and some use InterQual or MCG criteria. Confirm with each payer before scheduling elective cases.
• Emergent PCI: for acute myocardial infarction (AMI), most contracts waive prior authorization. Many still require notification within 24-48 hours.

When a required authorization is missing, the denial usually comes back as CO-197 (precertification or authorization absent) or a plan-specific code. These denials are rarely overturned on appeal without a new authorization.

Most 92920 denials trace back to a few fixable errors

A short list of root causes drives most 92920 denials. Learn the claim denial codes behind them, because a targeted denial management workflow fixes them faster than a general audit.

NCCI bundling edits fold these codes into 92920

The National Correct Coding Initiative (NCCI) treats certain codes as Column 2 components of 92920. They count as part of the balloon work and need a valid modifier to be reported. Edits update quarterly, so check the live NCCI table. Current relationships include the following.

• Certain diagnostic angiography codes (93454-93461): bundled when done in the same session as part of the intervention. Modifier -59 or XS applies only when the report shows a distinct decision point before the intervention began.
• Coronary catheter placement: placing the guiding catheter into the coronary arteries is included in 92920 and the other PCI codes.
• Radiological supervision: fluoroscopic guidance is already part of 92920 and cannot be reported separately.

Using -59 to override an edit without independent documentation is unbundling, and it carries False Claims Act risk. Your medical claims clearinghouse will not catch this, because documentation review is the only control.

The 0-day global period keeps follow-up visits billable

CPT 92920 carries a 0-day global period under the MPFS. No post-procedure services are bundled into the payment, so follow-up visits are billable from the day of the procedure. Major surgery, by contrast, often carries a 90-day global.

• Same-day E/M: a post-procedure evaluation on the day of PCI may be billable. It has to be a distinct, separately identifiable service beyond the standard post-op check.
• Modifier -24: this modifier covers unrelated E/M during a global period, so it does not apply to a code with a 0-day global.
• Complications: if the patient returns for a complication of the PCI, billing depends on the nature of the complication and the payer’s policy.

Check the global period in the CMS MPFS lookup before billing post-procedure services, because designations can change in annual updates.

Before you submit a 92920 claim, run this six-point check

Each point below maps to one of the denials above, so a claim that passes all six rarely comes back.

• The report names each major artery treated, and branch work sits under its parent artery.
• No stent was deployed in any artery billed as 92920.
• No deleted add-on code, such as 92921, 92929 or 92934, appears on a 2026 claim.
• Each additional major artery has its own primary line and the modifier the payer expects.
• Same-day diagnostic angiography carries -59 or XS only with a documented decision point.
• Elective cases carry a valid authorization number, and eligibility was confirmed before the procedure.

How claims management software keeps 92920 claims moving

Without a connected system, a PCI claim gets tracked across a payer portal, a clearinghouse login and a spreadsheet. Status checks happen by phone, and remittances get matched by hand.

Pabau, the practice management platform we build, keeps that work in one place. Its claims management software submits claims through Claim.MD and runs 270/271 eligibility checks before the procedure. Claim status and ERA remittances then come back into Pabau, so your team sees what was paid and what was denied.

The coding decisions in this guide still belong to your coders. What shrinks is the time spent chasing claims, which leaves more of the week for working denials against the operative report.

Conclusion

For 2026 dates of service, treat 92920 as a per-artery code. Branch work stays inside it, a stent moves that artery to 92928, and a second major artery earns its own line and modifier.

Update your charge templates and coder checklists now, and the deleted add-ons stop turning into CO-181 rejections. The cost is a closer read of each operative report, which is far cheaper than reworking denied claims.

Pabau keeps those claims visible from submission to remittance, so denials surface while you can still fix them. Book a demo to see how it handles PCI claims for your cardiology practice.
