CPT code 19286: Breast localization with ultrasound guidance

Key takeaways

CPT code 19286 describes percutaneous placement of a breast localization device with ultrasound imaging guidance for preoperative tumor localization.

19286 is an add-on code only. It cannot be billed as a standalone claim and must accompany the primary code 19285, since both require ultrasound guidance.

Billing 19286 as standalone or omitting the required primary code are the two most common denial triggers for this code family.

Pabau’s claims management software helps breast imaging and surgery practices track add-on code pairings, attach supporting documentation, and reduce claim errors.

CPT code 19286 describes the percutaneous placement of a localization device for preoperative breast tumor identification, performed under ultrasound imaging guidance. The American Medical Association (AMA) publishes and maintains the CPT code set. Within it, 19286 falls under the “Introduction Procedures on the Breast” section of the Surgery chapter.

The procedure involves a radiologist or surgeon inserting a device through the skin and into breast tissue, marking a non-palpable lesion before surgical excision. Common device types include a wire, clip, radar reflector, or radioactive seed.

Ultrasound guidance is integral to this code: if a different imaging modality is used, a different code in the 19281-19288 family applies. CPT code 19286 is specific to ultrasound-guided placement of a second or additional device in a single breast.

This is the detail that trips up many billers. Code 19285 covers the initial ultrasound-guided device placement. CPT code 19286 is the add-on reported when a second device is placed in the same breast during the same session.

Is CPT 19286 a standalone or add-on code?

CPT 19286 is strictly an add-on code. The claims management workflow for this code must always pair it with an eligible primary procedure code. Billing it as a standalone will result in automatic claim rejection. Payers and clearinghouses flag add-on codes submitted without a primary code on the same claim.

The table below shows the three primary codes in this family and clarifies which one CPT code 19286 actually pairs with.

CPT code 19286 pairs exclusively with 19285 in clinical practice, since both require ultrasound guidance. Codes 19281 and 19283 use different imaging modalities and have their own add-on codes, 19282 and 19284 respectively.

Mixing modality families on one claim is a common documentation error. For practices managing breast surgery billing, reviewing other CPT code families helps billers avoid crossover errors.

CPT code 19286 modifiers

Modifier selection for CPT code 19286 depends on the setting, laterality, and payer. The most commonly applicable modifiers are listed below.

Laterality modifiers (LT/RT) are required by Medicare and most commercial payers for unilateral breast procedures. Omitting them on a bilateral claim, where both breasts are localized in the same session, will typically cause one claim line to deny.

For guidance on maintaining modifier accuracy across your billing workflow, Pabau’s compliance management tools can flag missing modifier documentation before claims are submitted.

CPT code 19286 reimbursement and 2026 fee schedule

Reimbursement for CPT code 19286 under the Medicare Physician Fee Schedule (MPFS) is published annually by the Centers for Medicare and Medicaid Services, or CMS. Because this is an add-on code, Medicare pays for it in addition to the base payment for 19285. There is no separate status indicator issue that would suppress payment.

The table below shows indicative 2026 MPFS values. Verify current amounts using the FastRVU RVU lookup before finalizing any billing workflows. Geographic adjustment factors (GAFs) and the annual conversion factor update change the dollar amounts by locality.

Non-facility reimbursement is consistently higher for this code. The placing physician absorbs the cost of imaging equipment, supplies, and room overhead when working outside a hospital. Practices performing in-office ultrasound-guided localization should always confirm whether they are billing with or without the TC/26 split.

For practices running plastic surgery practices, tracking facility versus non-facility rates across the localization code family is worth a dedicated billing protocol. A single-setting switch can mean a meaningful difference in per-claim reimbursement across a high-volume breast imaging program.

Ultrasound guidance requirements for CPT 19286

Ultrasound imaging guidance is not optional for CPT code 19286 – it is definitional. A claim for 19286 without documented real-time ultrasound guidance is not a 19286 claim; it is a miscoded claim. The documentation requirements below must be met before the code is reported.

• Real-time imaging documented: the operative or procedure note must state that ultrasound guidance was used in real time during device placement. It is not enough to note that ultrasound was available.
• Permanent image record: at least one ultrasound image showing the device position in relation to the lesion must be retained in the patient record.
• Lesion identification: the note must describe the lesion being localized, including its approximate location and depth.
• Device type and placement confirmation: the type of localization device (wire, clip, seed, reflector) should be documented. Confirmation of its satisfactory position relative to the target lesion belongs in the same note.
• Separate report or integrated note: the imaging guidance component may be documented in the procedure note or a separate radiology report, depending on facility protocol.

Inadequate imaging documentation is one of the top audit triggers for the entire 19281-19288 code family. Breast imaging programs that want to keep documentation audit-ready benefit from structured procedure note templates. These prompt staff to capture each required element at the time of service, rather than reconstructing from memory later.

NCCI edits and bundling rules for CPT 19286

The National Correct Coding Initiative (NCCI) governs which code pairs can and cannot be billed together. Because CPT code 19286 is an add-on code, it receives somewhat different NCCI treatment than standalone procedures – but specific edit pairs still apply.

Key points for billing teams:

• Add-on status protects from many bundling conflicts: Medicare and most payers recognize that add-on codes are inherently reported with a primary code. The standard column 1/column 2 bundling logic that applies to standalone codes does not suppress 19286 when correctly paired with 19285.
• Ultrasound guidance is included: the imaging guidance for the device placement is bundled into CPT code 19286 itself. Do not separately report a standalone ultrasound code (such as 76942) for the guidance component of the 19286 service – this is a common unbundling error.
• Pathology and biopsy codes require care: a biopsy performed at the same session as the localization typically becomes the primary procedure. Localization becomes the add-on in that scenario. Review current NCCI tables quarterly, since edit pairs update on a rolling basis.
• Verify current NCCI tables: specific edit pairs must be confirmed against the current CMS NCCI tables before publication or billing workflow updates. Tables update quarterly.

For billers managing a high volume of breast procedure codes across the 19281-19288 family, the AAPC Codify CPT lookup is useful. It provides code-specific NCCI edit detail alongside the code descriptor. Cross-referencing this with the CMS NCCI table download gives the most complete picture of current bundling constraints.

Practices that track coding compliance across multiple procedure types can benefit from centralized documentation tools. Pabau’s CPT coding reference pages and digital forms help teams standardize documentation at the point of care, reducing the risk of post-submission audits.

Coding guidelines: When to report CPT 19286

Getting the reporting decision right for CPT code 19286 requires understanding two things: the imaging modality and the device count. Work through this sequence before coding any breast localization encounter.

1. Confirm imaging modality. Was ultrasound used in real time to guide the device placement? If yes, proceed. If another modality, such as mammographic, stereotactic, or MRI, was used instead, the correct primary code is 19281, 19283, or 19287 respectively.
2. Identify the primary code. The first ultrasound-guided localization device in the breast is reported with CPT 19285. That is the primary code.
3. Count additional devices. Each additional device placed in the same breast during the same session using ultrasound guidance is reported with one unit of CPT code 19286.
4. Apply laterality. If both breasts are localized, report primary and add-on codes for each breast separately with LT and RT modifiers.
5. Check for concurrent excisional procedures. When localization is performed immediately before an open excision or lumpectomy in the same operative session, report both procedures. Use the localization code(s) and the excisional procedure code together. They are not bundled together, since the localization is a distinct preoperative service.
6. Document before coding. Confirm that the operative note includes real-time ultrasound documentation, a permanent image, and device placement confirmation before finalizing the claim.

For surgical practices that coordinate between the radiology department and the operating room, the localization and excision often happen in separate locations. Both occur on the same day. Each service should be documented independently, with clear timestamps confirming the sequence of events. This matters for both coding accuracy and audit defense.

Practices looking to build consistent coding workflows across their breast procedure volume may find value in reviewing other procedure fee schedules. These frameworks show how to handle multi-step service documentation.

Common billing errors with CPT 19286

Denials for preoperative breast tumor localization coding cluster around a predictable set of mistakes. Knowing them in advance is cheaper than correcting them after the fact.

• Billing 19286 as a standalone code: the single most common error. Every clearinghouse and Medicare contractor will reject a 19286 claim line that lacks a primary code on the same claim date. The fix is straightforward – confirm the workflow always attaches 19285 before 19286 can be selected.
• Reporting ultrasound separately: some billing staff add a standalone ultrasound guidance code (76942) alongside 19286. The imaging guidance is already included in 19286 – reporting both is unbundling and triggers NCCI edits or audit flags.
• Wrong modality code family: a procedure note that says “under sonographic guidance” but uses 19282 (mammographic add-on) is a mismatch that can trigger a probe. Modality language in the note and the CPT code must align.
• Missing laterality on bilateral cases: when both breasts are localized, each side needs its own claim line with the appropriate LT or RT modifier. Submitting both on a single line without laterality results in one denial.
• Inadequate ultrasound documentation: a procedure note that only says “ultrasound was used” is insufficient for most payers. It must specify real-time guidance, a permanent image, and lesion identification, or it will not survive a medical records request.

Breast imaging programs that use standardized documentation templates for procedure notes report fewer post-submission corrections. The required elements are built into the workflow rather than left to individual recall.

A regular medical chart audit catches missing documentation before a payer does. It works by checking that documentation checkpoints sit in the day-of-procedure workflow, not the day-of-billing workflow.

CPT 19286 coding example

The following scenario illustrates a correctly coded claim for CPT code 19286.

Clinical scenario: A patient presents for preoperative ultrasound-guided wire localization of two non-palpable lesions in the right breast, both scheduled for excision the same morning.

The radiologist places the first wire under real-time ultrasound guidance, images the position, and confirms satisfactory placement. A second wire is placed for the second lesion using the same ultrasound guidance. Both are documented in a single procedure note with permanent images retained.

• Primary code: 19285 RT (percutaneous breast localization device placement, first lesion, ultrasound guidance, right side)
• Add-on code: 19286 RT (additional device placement, ultrasound guidance, right side)
• Modifier: RT applied to both codes to designate right breast
• Documentation required: real-time ultrasound noted in procedure report; two permanent images retained; lesion locations and wire positions described; device type (wire) confirmed
• Do not separately report: a standalone ultrasound guidance code – it is bundled into both 19285 and 19286

If this same patient also underwent excisional biopsy of both lesions in the same operative session, the excision codes would be reported too. These are added to the localization codes, not used instead of them. The codes fall in the 19120-19301 range, depending on the type of excision performed, and the localization and excision remain distinct billable services.

Practices managing complex breast procedure schedules benefit from a billing workflow that pulls documentation from both the radiology procedure note and the surgical operative report. This matters most when localization and surgical excision happen in rapid sequence across multiple rooms.

Pabau’s client record management tools let teams attach and cross-reference documents from multiple encounters on the same date. This reduces the risk of missing supporting documentation at claim submission.

Related CPT codes in the breast localization family

CPT code 19286 is one of eight codes in the 19281-19288 breast localization device placement family. Understanding the full family prevents modality mismatches and helps coders select the correct primary-plus-add-on pairing for every session.

The pattern is consistent across all four modality pairs. An odd-numbered primary code covers the first lesion, and the immediately following even-numbered add-on code covers each additional lesion using the same imaging modality. CPT code 19286 is the ultrasound-modality add-on in this structure.

Coders managing breast imaging billing for women’s health practices should have this full code family mapped in their coding reference materials to prevent modality-mismatch denials. Reviewing the related excision code CPT 19125 clarifies what happens after localization is complete.

How Pabau strengthens breast procedure billing accuracy

Many breast imaging and surgical practices still catch add-on code errors after a payer denial. A biller then works backward through the clearinghouse rejection to find the missing primary code.

Pabau’s claims management software checks that pairing before the claim ever leaves the practice. It flags a 19286 line that lacks its 19285 primary code and surfaces missing modifiers like LT, RT, or XS.

The result is fewer denials tied to add-on code pairing and less time spent on resubmissions. It also means a clearer audit trail if a payer requests supporting documentation.

Catch add-on code errors before submission

Pabau's claims management software checks that add-on codes like 19286 carry their required primary code and modifiers before a claim leaves the practice. This reduces denials and rework for breast imaging and surgical teams.

Conclusion

The most preventable denials for CPT code 19286 come from a single misstep: submitting it without the required primary code 19285. After that, the next-biggest risk is unbundling the ultrasound guidance component by separately reporting 76942. Both errors are entirely avoidable with the right documentation templates and a billing workflow that flags add-on codes for primary-code verification before submission.

Pabau’s claims management software helps breast imaging and surgical practices build those checkpoints directly into their billing process. Coders then see the full claim picture before it leaves the practice. Book a demo to see how Pabau supports procedure code documentation and claim workflows for your team.
