HCPCS code G0296 – Lung cancer screening counseling visit

Key takeaways

HCPCS Code G0296 bills the lung cancer screening counseling and shared decision-making visit, while the LDCT scan itself is billed separately.

G0297, the original LDCT scan code, was terminated, and CPT 71271 now covers the scan.

Medicare covers G0296 as a Part B preventive service with no patient cost-sharing, provided every SDM element is documented.

Medicare requires the G0296 visit only before the first LDCT screen. Annual repeat screens need a written order instead.

Medicare eligibility under NCD 210.14 runs from age 50 to 77, while most commercial plans follow the USPSTF range of 50 to 80.

HCPCS Code G0296: Definition and clinical purpose

HCPCS Code G0296 is the Level II code for the counseling visit that precedes a patient’s first low dose CT (LDCT) lung cancer screen. The descriptor’s closing parenthetical names its two jobs: eligibility determination and shared decision making (SDM). The code is maintained by the Centers for Medicare and Medicaid Services (CMS). Medicare covers it as a preventive service under National Coverage Determination (NCD) 210.14.

During the visit, the practitioner confirms the patient is eligible and talks through the benefits and harms of screening with a decision aid. It closes with a written order for the scan, which is billed separately under CPT 71271. Medicare requires this visit only before the first screen. Annual repeat screens need a new written order, not a new G0296 visit.

Official code details at a glance

What the G0296 visit covers — and what it does not

The G0296 visit covers a fixed set of clinical tasks, and auditors check chart notes against that list.

Covered by G0296:

• Confirming the patient meets the NCD 210.14 eligibility criteria for LDCT screening
• The shared decision-making discussion of LDCT’s benefits, limitations and risks (including incidental findings), using one or more decision aids
• Counseling on sticking with annual screening and on the importance of quitting or staying smoke-free
• Documenting smoking history, including the pack-year calculation
• Issuing the written order for the LDCT scan, billed under CPT 71271

Not covered by G0296 (common confusion points):

• The LDCT scan itself (billed as CPT 71271, not G0296)
• Tobacco cessation counseling services (billed separately using the applicable cessation codes)
• Routine evaluation and management services (an E&M on the same date requires Modifier 25)
• Diagnostic imaging ordered for symptomatic patients (LDCT screening applies only to asymptomatic, high-risk beneficiaries)

When a current smoker accepts a full cessation session on the same day, it is reported on its own line. A session of three to 10 minutes is billed as CPT 99406.

Who qualifies: Medicare eligibility criteria for G0296

A G0296 claim is payable only when the beneficiary meets every criterion in NCD 210.14. CMS updated the NCD in 2022 after the USPSTF 2021 Grade B recommendation, but it aligned only in part. It lowered the smoking threshold from 30 to 20 pack-years and the starting age from 55 to 50. It kept the 15-year quit window and the upper age of 77, while the USPSTF runs to 80.

Current Medicare eligibility requirements under NCD 210.14:

• Age 50 to 77 years (the prior CMS criterion was 55 to 77, and the USPSTF’s 50 to 80 does not apply)
• At least a 20 pack-year smoking history
• Current smoker or former smoker who quit within the past 15 years
• Asymptomatic: No signs or symptoms of lung cancer at the time of the visit
• No current lung cancer diagnosis or lung cancer treatment in progress

If any criterion is not met, the claim will be denied as not medically necessary. The record must document each item explicitly. A note that only reads “patient eligible for lung cancer screening” will not hold up.

Which providers can bill G0296

The G0296 visit is furnished by a physician or a qualified non-physician practitioner (NPP), such as a nurse practitioner, physician assistant or clinical nurse specialist. State scope-of-practice rules and Medicare enrollment status decide which of them can bill in your practice. Confirm incident-to rules with your Medicare Administrative Contractor (MAC) before billing a visit under a supervising physician’s NPI.

How the G0296 visit is performed and documented

G0296 documentation requirements are where most claims fail audit. Auditors look for each element of the SDM visit in the chart note. An LDCT order on its own does not show that the counseling happened. A structured visit form with one field per NCD element keeps steps from being skipped and speeds up claim preparation.

Required documentation elements for G0296 claims

The following checklist maps each clinical act to the documentation element a payer auditor expects to find in the record:

ICD-10 diagnosis codes to report with HCPCS Code G0296

Every HCPCS Code G0296 claim needs at least one supporting ICD-10-CM diagnosis code. The primary code tells the payer the visit is a screening encounter. Secondary codes record tobacco status: Z87.891 for former smokers, and F17.210 for most current cigarette smokers.

Verify the specific combination of diagnosis codes accepted by each MAC before submitting. Some MACs publish Local Coverage Articles (LCAs) with an explicit covered-diagnosis list for G0296 claims.

G0296 reimbursement: Medicare payment rates

Medicare pays for G0296 under the Medicare Physician Fee Schedule (MPFS), administered by CMS. Because G0296 is a Part B preventive service, the patient owes no deductible or coinsurance. That holds when every eligibility criterion is met and the claim is coded correctly. In Pabau’s claims management software, each claim is scrubbed for missing or invalid details before it goes to the payer.

Payment rates change annually with the MPFS update. The specific dollar amount varies by location and practice setting because of geographic practice cost index (GPCI) adjustments. Use the CMS fee schedule lookup or your clearinghouse’s rate tool to confirm the current allowed amount in your area. Commercial payers are not required to cover G0296 at Medicare rates, and coverage terms vary by plan.

How G0296, G0297 and CPT 71271 relate

G0297 was the original HCPCS code for the LDCT lung cancer screening scan. CMS terminated G0297, and CPT 71271 replaced it as the billing code for the scan itself. G0296 has always described the counseling visit, never the scan. Some older workflows and billing guides still list G0297 as if it were active.

Billing G0296 alongside an E&M visit

G0296 can be billed on the same date as a significant evaluation and management (E&M) service. When it is, append Modifier 25 to the E&M code. The modifier shows the E&M was separately identifiable from the preventive counseling visit. Without Modifier 25, the E&M and G0296 are bundled together, and one service is denied.

The SDM discussion must be documented as a distinct encounter from any other clinical content addressed that day. A single progress note that buries the G0296 elements inside a routine office visit narrative is a common audit failure.

Modifiers for G0296

G0296 itself does not typically require a modifier. Verify current National Correct Coding Initiative (NCCI) edits and MAC-specific policies before adding modifiers not driven by a specific edit or denial.

When G0296 is required, and when it is not

Under NCD 210.14, Medicare requires the G0296 counseling and SDM visit only before a beneficiary’s first LDCT screen. Each annual repeat screen under CPT 71271 needs a new written order instead of a new G0296 visit. If a practice repeats the counseling visit in a later year, check the MAC’s frequency edits before billing it again.

Eligibility still has to be re-confirmed before every repeat screen. A patient who turns 78, or who passes 15 years since quitting, no longer qualifies under Medicare. The two paths look like this side by side:

Common reasons G0296 claim denials occur

G0296 claim denials cluster around predictable failure points. Reading the denial codes on a G0296 remittance shows which element failed and what to correct before resubmission.

Payer-specific coverage policies for HCPCS Code G0296

Medicare coverage under NCD 210.14 is the clearest framework for G0296. Commercial payers handle this code differently, which complicates billing for practices with a mixed payer population.

Medicare: NCD 210.14 governs coverage nationally, with no cost-sharing for the patient. The counseling and SDM visit is required before the initial LDCT screening only, and eligibility follows the criteria above. MACs implement the NCD and may publish LCAs with extra covered diagnosis lists or documentation guidance for their jurisdiction.

Commercial payers: Coverage and cost-sharing vary. Most commercial plans cover lung cancer screening counseling as a preventive service. The Affordable Care Act requires them to cover USPSTF Grade A and B recommendations. Those plans follow the USPSTF age range, so a commercial plan may cover a 79-year-old whom Medicare would not.

Commercial plans may also use a different code, require prior authorization, or apply cost-sharing if the visit is not coded as preventive. Contact each payer to confirm whether it recognizes G0296 or maps the visit to a CPT equivalent.

Medicaid: Coverage of G0296 varies by state. Verify with the state Medicaid agency before billing.

How Pabau keeps G0296 and CPT 71271 claims clean

Without a structured note, G0296 documentation depends on memory. A decision aid goes unrecorded, the pack-year history is written as a range, or the first-screen order never gets tied to the counseling visit. The claim goes out anyway and comes back weeks later.

Pabau lets you build the SDM visit as a custom form with a field for each NCD 210.14 element. The note is then complete before it is signed. Before a claim leaves Pabau, it is scrubbed for missing or invalid details. US claims go out as CMS-1500s through Claim.MD, and insurance eligibility can be verified through Claim.MD before the visit.

If a claim comes back rejected, Pabau flags it as needing action and shows the reason, so your team can correct and resubmit it. Payments then post from the electronic remittance advice (ERA) file instead of being keyed in by hand.

Conclusion

G0296 pays when the chart proves the visit happened the way NCD 210.14 describes it. Build your SDM note around the NCD elements, record pack-years as a number, and tie the first-screen order to the visit date.

The change with the biggest payoff is in repeat years. If your workflow books a new G0296 visit every year, drop it for returning patients. Re-check their age and quit date instead, then issue the written order for the next CPT 71271 screen.
