CPT code 19325: Augmentation mammoplasty billing guide

Key takeaways

CPT code 19325 covers breast augmentation with implant(s), the AMA descriptor adopted in 2021 for cosmetic and reconstructive implant placement.

Medicare treats cosmetic augmentation as a statutory exclusion, so no Advance Beneficiary Notice is required before you bill the patient.

Bilateral augmentation needs modifier 50, or RT and LT on two line items, depending on the payer’s billing manual.

Missing modifiers and mismatched diagnosis codes cause most 19325 denials, so check both before the claim leaves the practice.

Pabau’s claims management software captures codes, applies modifiers, and tracks prior authorization inside one billing workflow.

CPT code 19325 is the billing code for breast augmentation with an implant. Plastic surgeons, breast surgeons, and reconstructive specialists use it whenever they place a prosthetic breast implant. It covers cosmetic volume enhancement as well as reconstruction after mastectomy or trauma.

The American Medical Association (AMA) publishes the official descriptor for 19325 and issues coding guidance through CPT Assistant. AMA reworded that descriptor in 2021, so older payer policies often quote language the code book no longer uses. The AMA code set also governs HIPAA-compliant electronic claims, which makes 19325 the recognized procedure code for every US payer.

How the procedure is documented decides whether the claim pays. Practices that standardize plastic surgery EMR documentation around the operative record have far less to fix on appeal. This reference covers the code description, RVU data, modifiers, Medicare rules, ICD-10 pairings, documentation requirements, and related breast codes.

Official code description and procedure details

The official AMA descriptor for CPT code 19325 reads: Breast augmentation with implant(s). The code covers surgical insertion of a breast implant for augmentation. It applies to subglandular, submuscular, and dual-plane approaches, and to both saline and silicone gel implants.

Before 2021 the same code read “Mammoplasty, augmentation with prosthetic implant”, and 19324 covered augmentation without an implant. AMA deleted 19324 that year and reworded 19325. If a payer policy still quotes the old descriptor, the code number itself has not changed. Bill 19325 and cite the current wording in any appeal.

CPT 19325 covers the primary augmentation only. If the surgeon also performs a breast lift, that component may be reported separately with 19316, subject to payer bundling rules. Tissue reinforcement under 15777 is sometimes billed alongside 19325, though payer policies vary on it.

CPT 19325 fee schedule and reimbursement rates

Most breast augmentation billed under 19325 is cosmetic, so neither Medicare nor most commercial plans pay for it. Where the procedure is covered as reconstruction, payment follows the CMS Physician Fee Schedule. The CMS fee schedule lookup returns current facility and non-facility rates by locality.

RVU values and the conversion factor change every year. Check each component against the fee schedule for the year you are billing before quoting a rate. Commercial payers set their own schedules, which often differ from Medicare. For cosmetic augmentation the surgeon’s fee is paid by the patient rather than an insurer.

Medicare and insurance coverage for CPT code 19325

Medicare does not cover CPT code 19325 when the augmentation is cosmetic. CMS treats cosmetic surgery as a statutory exclusion under Section 1862(a)(10) of the Social Security Act.

Because that exclusion is statutory, Medicare does not require an Advance Beneficiary Notice (ABN) before you bill the patient. Many practices still issue one voluntarily and append modifier GX to the claim line. That puts it in writing that the patient was told the service is not covered.

Cosmetic vs reconstructive: How payers decide

Reconstructive implant placement may qualify for coverage when the record shows a medical or surgical indication. Covered scenarios usually include post-mastectomy reconstruction, correction of a congenital breast deformity, or reconstruction after trauma. Anyone setting up a cosmetic surgery practice should separate the two case types in the record from the first visit.

• Cosmetic augmentation (not covered by Medicare or most payers): The patient wants a larger breast size and there is no documented medical indication. Billed with Z codes such as Z41.1. The patient pays out-of-pocket.
• Reconstructive augmentation (may be covered): Implant placement after mastectomy, trauma, or correction of a congenital deformity. Requires clinical documentation of the indication, and often a prior authorization as well.
• Local Coverage Determination (LCD): Medicare Administrative Contractors (MACs) issue the LCDs that govern coverage for breast procedures. Check your MAC’s current LCD before submitting a reconstructive claim.

Commercial payers such as BCBS, Aetna, Cigna, and UnitedHealthcare each maintain their own medical policy for breast augmentation, so coverage for reconstruction varies by plan. Some policies cover post-mastectomy reconstruction under the Women’s Health and Cancer Rights Act (WHCRA). That law requires a plan covering mastectomy to cover reconstruction as well.

Prior authorization requirements

Prior authorization for 19325 depends on the payer and on whether the case is cosmetic or reconstructive. Cosmetic procedures rarely need it, because they are not covered in the first place. For reconstructive cases, most commercial payers require authorization before the procedure is performed.

• Submit clinical notes documenting the medical indication, such as mastectomy records, a congenital diagnosis, or trauma history
• Include the planned CPT code (19325) and the relevant diagnosis codes
• Attach operative reports from prior procedures where they apply
• Allow for payer review timelines, which usually run 3 to 14 business days depending on urgency

Never rely on verbal confirmation of an authorization. Get written approval and file it in the patient record before the procedure date. Practices using plastic surgery billing software can track authorization status next to the appointment, so nobody operates on an unconfirmed case.

Modifiers for CPT code 19325

Modifier selection decides whether a 19325 claim pays in full, pays at a reduced rate, or denies outright. Check the AAPC code reference and the payer’s own modifier policy before you submit. Name the clinical scenario first, then pick the modifier that matches it.

Bilateral breast augmentation billing

Bilateral augmentation is the standard case, and the billing approach follows payer preference. Most payers accept modifier 50 on a single line of 19325. Others want two consecutive lines, 19325-RT and 19325-LT. Check the payer’s billing manual before you submit. With modifier 50, reimbursement is typically 150% of the single-procedure rate.

ICD-10 diagnosis codes for CPT 19325

The diagnosis code paired with 19325 tells the payer whether the procedure is cosmetic or reconstructive. Cosmetic augmentation uses Z codes. Reconstructive indications need a code that documents the clinical reason for surgery. Confirm the accepted pairings in your payer’s medical policy before submitting.

Pairing Z41.1 with a reconstructive claim is a compliance risk. The diagnosis code has to match the operative report and the pre-operative notes. A cancer history coded Z85.3 supports the reconstructive context, but it does not establish medical necessity on its own. Payers audit these pairings, and mismatches are a leading cause of post-payment review in plastic surgery.

Documentation requirements for breast augmentation billing

Incomplete documentation is the main reason 19325 claims fail on appeal. Every claim needs a complete operative record behind it before it goes out the door. Practices using digital intake forms can standardize the pre-operative record, so the file is already complete at the point of care.

• Pre-operative consultation note: Records the patient’s stated reason for surgery, examination findings, breast measurements, and the surgeon’s assessment of the indication.
• Operative report: Names the procedure performed, the surgical approach, the implant type and size, and any concurrent procedures.
• Implant documentation: Manufacturer, lot number, and product specifications. Required for FDA device tracking and for commercial payer audits.
• Photographs: Standardized pre-operative photographs support the clinical record, and they carry the most weight on reconstructive claims.
• Consent forms: Signed informed consent covering risks, alternatives, and whether the procedure is cosmetic or reconstructive.
• Reconstructive justification letter: A separate letter of medical necessity from the surgeon strengthens prior authorization requests and appeals.

For reconstructive billing, the record has to connect the implant placement to the covered indication. A cosmetic operative note filed with a reconstructive diagnosis code is an audit trigger. Specific documentation from the first consultation through to the operative report is what protects the practice during payer review.

Global period and post-operative billing for CPT 19325

CPT code 19325 carries a 90-day global surgery period under the standard CMS rules for major procedures. The surgeon’s post-operative care inside those 90 days is bundled into the 19325 payment. Routine follow-up visits within the window cannot be billed separately.

• Included in the global package: All routine post-operative visits within 90 days, wound checks, suture removal, and management of expected complications.
• Separately billable with modifier 24: An evaluation and management (E/M) service for a problem unrelated to the post-operative care of 19325.
• Separately billable with modifier 79: An unrelated surgical procedure performed during the global period.
• Separately billable with modifier 58: A staged or related procedure planned in advance, such as an implant exchange or a revision.

Billing a routine follow-up inside the 90-day window without the right modifier is a common compliance error. Practices billing 19357 hit the same problem, because every expansion visit inside its global period is bundled too. A system that flags open global periods against incoming appointments removes most of that risk.

Related CPT codes for breast procedures

Plastic surgery billing staff cross-reference 19325 with the adjacent breast codes constantly. Most coding errors in this specialty come from picking the wrong one, or from billing two together where the payer bundles them. Revision work on a reconstructed breast belongs to 19380 rather than 19325.

Mastopexy (19316) and augmentation billed together

Augmentation with a simultaneous breast lift is a common combination. AMA CPT Assistant guidance allows 19325 and 19316 to be reported together when both procedures are distinctly performed. Many commercial payers still bundle them and pay only the higher-value code. Verify the payer’s bundling edits first. Append modifier 59 to the secondary code where policy permits separate reporting.

Breast reduction (19318) vs augmentation mammoplasty (19325)

CPT 19318 covers breast reduction, the removal of tissue to reduce breast size. 19325 does the opposite and adds volume with an implant. The two are not interchangeable and never belong on the same claim for the same breast. Coverage differs as well. Reduction for documented macromastia is often covered where cosmetic augmentation is not.

Common coding errors and how to avoid them

CPT 19325 claims fail for predictable reasons. Five root causes account for most of the denials plastic surgery coders see.

• Wrong modifier for a bilateral procedure: Submitting 19325 without modifier 50, or without RT and LT on two line items. The claim processes as unilateral and pays at the single-procedure rate.
• Mismatched diagnosis code: Pairing a reconstructive code such as Z42.1 with documentation that reads as cosmetic, or the reverse. Payers flag this on claim review and on audit.
• Billing post-operative visits during the global period: Routine follow-up inside 90 days is bundled. Billing it separately without a modifier causes an adjustment or a refund demand.
• Unbundling 19325 and 19316 without payer approval: Billing the lift and the augmentation together where the payer bundles them. Many payers pay only the dominant procedure.
• Missing or incomplete operative report: Filing the claim before the operative report is finalized and attached. This is a common cause of technical denials and delayed payment.

A pre-submission checklist built into the billing workflow catches most of these before the claim leaves the practice. It matters most for practices running on med spa software, where aesthetic and surgical procedures are billed side by side and modifier discipline slips easily.

How practice management software supports CPT 19325 billing

Billing 19325 spans pre-operative documentation, prior authorization, the operative note, modifier selection, and global period tracking. Every one of those steps can sink the claim. Looking a code up in a reference tool and retyping it into a billing platform adds transcription errors and missed modifiers on top.

Practice management software like Pabau brings code capture, modifier application, and claim submission into a single workflow. Pabau’s claims management software is built for aesthetic and surgical specialties, so 19325 surfaces during documentation rather than after it. The same platform gives plastic surgery practices one place to track authorization status against the patient record.

The payoff is fewer modifier errors, faster claim submission, and denial trends you can see across the whole practice. Take a practice billing 20 bilateral augmentations a month at the unilateral rate because modifier 50 was missing. A year of that is a serious amount of underpayment a systematic workflow would have caught.

Streamline CPT billing for your plastic surgery practice

Pabau helps plastic surgery and aesthetic practices capture CPT codes, apply modifiers, manage prior authorizations, and submit claims without switching between systems.

Conclusion

Three decisions settle a 19325 claim, and all of them happen before it is submitted. Is the procedure cosmetic or reconstructive, which modifier applies, and does the operative note support both answers? Get those right at the point of care and there is nothing to appeal later.

Cosmetic work is straightforward to bill, because the patient pays and no coverage decision is involved. Reconstructive work only pays when the record earns it. That record is built in the consultation room, not in the billing queue.

If your denial log keeps showing the same two or three causes, the fix belongs in the workflow rather than with the coder. Book a demo to see how Pabau captures codes, applies modifiers, and tracks prior authorization in one place.
