CPT code 77062: Bilateral diagnostic breast tomosynthesis

Key takeaways

CPT code 77062 reports diagnostic digital breast tomosynthesis, bilateral. A diagnostic study of one breast is 77061.

Laterality sits inside the descriptor, so 77062 carries no RT or LT modifier and no modifier 50. It bills as one line item.

Medicare does not accept 77062. The fee schedule lists it as status indicator I with 0.00 RVUs. Medicare claims go out as 77065 or 77066 with add-on HCPCS code G0279.

Commercial and Medicaid plans that do accept the code still want a symptomatic or indeterminate-finding ICD-10 code, never the screening code Z12.31.

Practice management software like Pabau attaches codes at the point of care, so the code set each payer expects reaches the claim.

Most claim failures on 77062 start with the payer, not the radiology suite. Medicare does not recognize the code at all, and a one-breast diagnostic study belongs on 77061. Either mistake costs a denial and a week of rework. Getting CPT code 77062 right means knowing the descriptor, the payer split behind it, and the ICD-10 pairing that carries medical necessity.

The American Medical Association’s CPT code set overview places 77062 in the Breast, Mammography subsection of the Radiology chapter. The AMA introduced 77061, 77062, and 77063 effective January 1, 2015. Each code in that family carries its own clinical indication, laterality rule, and payer handling.

CPT code 77062: official description and code details

Official AMA descriptor: Diagnostic digital breast tomosynthesis; bilateral.

Digital breast tomosynthesis (DBT) takes multiple low-dose X-ray images of the breast from different angles, then reconstructs them into a three-dimensional dataset. That improves lesion detection in dense breast tissue compared with standard two-dimensional mammography.

CPT code 77062 covers the acquisition and interpretation of that dataset for both breasts, in a diagnostic context. Diagnostic means the patient has signs, symptoms, or an imaging finding that needs further evaluation.

Diagnostic vs screening: where CPT code 77062 fits the DBT family

Three questions decide the code. Is the encounter diagnostic or screening, was one breast imaged or both, and does the payer accept the CPT tomosynthesis codes?

A diagnostic encounter happens when the patient presents with a new symptom, such as a palpable mass, nipple discharge, or a skin change. It also applies when a prior study produced an indeterminate result that needs clarification. A screening encounter happens in an asymptomatic patient under routine surveillance.

Laterality is not a modifier decision on this code. A diagnostic tomosynthesis study of one breast is 77061, and a study of both breasts is 77062. Because 77062 already covers both sides, it goes out as a single unit on a single claim line. Two units of 77062 for the same session duplicate the bilateral service.

Modifiers for CPT code 77062

77062 takes component modifiers, not laterality modifiers. RT, LT, and modifier 50 all restate something the descriptor already says, so the useful decisions are about who bills which part of the service.

Component modifiers carry most of the risk here. When a radiologist reads the study in a hospital or imaging center, modifier 26 bills the interpretation alone. The facility then files its own claim with modifier TC. Billing the global code in a split arrangement overstates the claim and creates a compliance exposure.

Adding RT or LT to 77062 is the more visible error, and it usually comes from a charge template built for a unilateral code. Some payer systems reject the line, others pend it for review, and either way somebody reworks the claim.

ICD-10 codes that support medical necessity for 77062

Every payer that covers diagnostic tomosynthesis requires a linked ICD-10-CM diagnosis code that demonstrates medical necessity. The CMS ICD-10 codes page maintains the current tabular list for verification. The most commonly paired diagnosis codes fall into four clinical indication categories.

The ICD-10 code has to match the clinical documentation. Attaching Z12.31 to a diagnostic DBT claim is a common and auditable error, since that code belongs with screening codes 77067 and 77063. Use the AAPC’s CPT code lookup tool to cross-reference pairings when you verify medical necessity.

Because 77062 covers both breasts, the record should show why each side was imaged. A single unilateral finding with no stated reason for the second view is the detail an auditor asks about first.

How Medicare pays for diagnostic tomosynthesis: G0279, not 77062

Medicare does not pay 77062. The CMS Physician Fee Schedule relative value file marks both 77061 and 77062 with status indicator I, meaning neither is valid for Medicare purposes. Both carry 0.00 RVUs, so no locality-adjusted rate exists to bill against.

Medicare pays for the tomosynthesis through the add-on HCPCS code G0279 instead, reported on the same claim as diagnostic mammography code 77065 or 77066. For a bilateral diagnostic study, that pairing is 77066 plus G0279. Our HCPCS code G0279 billing guide covers the add-on rules in detail.

Screening works the other way around, which is where coders get caught. Medicare does accept CPT 77063 as the screening tomosynthesis add-on to 77067. So the CPT add-on is fine for screening, while the diagnostic study needs the G code.

Medicare Advantage plans generally follow the Medicare code set, so expect the G0279 pairing there too. Confirm it with the plan before the claim goes out, because edits differ by carrier.

Reimbursement and fee schedule context for CPT 77062

There is no Medicare fee schedule amount for 77062, because the code sits outside the schedule. Whatever the code pays comes from the commercial contract, so allowed amounts differ by payer and by region.

The CMS Physician Fee Schedule lookup tool is still worth opening. It shows the status indicator on 77061 and 77062, and it carries the payable rates for 77065, 77066, and G0279 in each locality.

How the claim is split changes the amount as well. A practice that owns its imaging equipment and employs its radiologists bills the global service with no component modifier. A hospital-based radiologist bills modifier 26, leaving the facility to bill TC. After submission, electronic remittance advice (ERA) files confirm what each payer actually allowed.

Pabau integrates with Claim.MD to submit claims through Claim.MD, routing tomosynthesis claims to over 4,000 US payers in the 837P electronic format. ERAs come back as 835 remittance files for automated reconciliation.

Tracking how tomosynthesis reimbursement trends over time matters as much as knowing the current rate. Pabau’s reporting lets imaging practices monitor revenue by code. A payer that keeps underpaying its contracted rate then shows up as a pattern, not a one-off. That gives billing teams the revenue cycle management view a fee schedule lookup cannot.

Commercial payer coverage and prior authorization

Coverage for 77062 is a plan-by-plan question, since Medicare is out of the picture. Commercial policies differ on three points. Does the plan accept the CPT tomosynthesis codes, does tomosynthesis need prior authorization, and is the 3D acquisition bundled into the mammography payment?

Coverage criteria still center on a documented clinical indication: a palpable mass, nipple discharge, a skin change, asymmetry on prior imaging, or an indeterminate result. No payer covers diagnostic tomosynthesis for routine screening, and that distinction has to show up in both the ICD-10 code and the record.

Completing insurance eligibility verification before the encounter matters more for this code than most. It settles the code set and the authorization question in one step. Confirm both at scheduling, not after the study is performed.

• Medicare: 77062 is not payable. Bill 77066 with add-on G0279 and document the clinical indication for the tomosynthesis.
• Commercial payers: most accept 77061 and 77062, but some mirror Medicare and want the G code. Check the plan’s policy before scheduling.
• Prior authorization: some plans require it for tomosynthesis, even where standard diagnostic mammography needs none.
• Medicaid: coverage varies by state, and some programs pay for 2D mammography only. Verify rather than assume.

Documentation requirements for CPT 77062

Documentation deficiencies are the second most common reason for 77062 denials, after code set and modifier errors. Every claim for this code needs a record that addresses specific elements.

• Clinical indication: the reason the study was ordered, recorded in the ordering provider’s note (mass, discharge, abnormal prior imaging)
• Ordering provider: name and NPI of the provider who ordered the diagnostic tomosynthesis
• Laterality: confirmation that both breasts were imaged, with findings stated for each side
• Radiologist interpretation: a signed report with findings, impression, and clinical recommendation
• Study date: date of service matching the claim
• Equipment documentation: confirmation that tomosynthesis was performed, not standard 2D mammography

The radiology report is the primary documentation vehicle. It has to state that digital breast tomosynthesis was performed, not simply mammography, and it has to cover both breasts. A report that lists findings without naming the modality creates an audit exposure.

Maintaining medical billing compliance for imaging codes means the report language lines up with the CPT descriptor. Practices using structured reporting templates cut ambiguity by building modality and laterality fields into every DBT report.

For practices handling a high volume of imaging studies, superbill and CMS-1500 export workflows help. They auto-populate modality and laterality from the clinical record, so the claim form and the radiology report agree.

Common billing errors and how to avoid them

Most denials and audit findings on 77062 trace to six patterns. Each one is correctable with a policy or workflow change rather than an appeal.

• Sending 77062 to Medicare: the code is not valid for Medicare purposes, so the line denies. Bill 77066 with add-on G0279 instead.
• Reporting 77062 for one breast: a single-breast diagnostic study is 77061. The bilateral code overstates what was performed.
• Appending RT or LT to 77062: laterality already sits in the descriptor. The side modifier either rejects the line or holds it for review.
• Pairing 77062 with Z12.31: the screening encounter code belongs with 77067 and 77063. Diagnostic tomosynthesis needs a symptomatic or indeterminate-finding code.
• Billing 77061 and 77062 together: they are the unilateral and bilateral versions of one service. Report the one that matches the study.
• Split-billing modifier errors: in a TC and 26 arrangement, the radiologist appends 26 and the facility appends TC. Dropping either modifier misprices both claims.

Effective denial management workflows for 77062 categorize every denial by root cause. Code set errors and screening-versus-diagnostic mismatches are both fixable at charge entry, well before an appeal. Working through denial codes in medical billing systematically brings the clean-claim rate up over time.

How practice management software simplifies digital breast tomosynthesis billing

A coding reference tells you what 77062 means. It does not know which payer the study is going to, and that is where the wrong code set enters the claim. The decision gets made in the clinical workflow, minutes after the radiologist signs the report.

Pabau embeds procedure coding into the appointment and treatment workflow. When a radiologist completes an interpretation, the claims management software lets the code, modifier, and linked ICD-10 be attached at the point of care. Nobody re-keys them into a separate billing system, so the transcription step that produces code selection errors goes away.

For practices submitting imaging claims in the 837P format, Pabau’s Claim.MD integration routes them to over 4,000 US payers. It validates each claim against payer-specific edits before transmission. Coders see rejection reasons before the claim reaches the payer, which cuts rework on codes like 77062. Status updates on each 837P electronic claim file come back automatically.

Streamline imaging billing from the point of care

Pabau attaches CPT codes, modifiers, and ICD-10 pairings at the time of service, reducing transcription errors and accelerating claim submission for radiology and imaging practices.

Conclusion

CPT code 77062 has a narrow set of requirements. It needs a diagnostic indication, both breasts imaged, no laterality modifier, and a payer that accepts the CPT tomosynthesis codes. Medicare is not that payer, so those studies go out as 77066 with add-on G0279. Once a billing team internalizes that split, most denials on this code disappear.

The remaining errors are systematic rather than random, and they happen at charge entry and documentation, not in the radiology suite. To see how Pabau handles code selection, modifier attachment, and claim submission, book a demo. We will walk through the radiology billing workflow with you.
