HCPCS Code J7298: Levonorgestrel IUD billing, Medicare, and claims

Key Takeaways

HCPCS Code J7298 is the brand-specific code for Mirena (Bayer), a 52 mg levonorgestrel-releasing IUD; Liletta bills under its own code, J7297, not J7298

Bill one unit of J7298 per device supplied; pair it with CPT 58300 for insertion — the same code applies whether or not hysteroscopic guidance is used, since there’s no dedicated hysteroscopic-guided IUD placement code

Medicare Part B reimbursement is based on ASP+6%; rates change quarterly and must be verified against the current CMS ASP file before billing

Pabau’s claims management software helps OB/GYN and family practice teams submit J7298 claims with accurate unit counts, modifiers, and paired CPT codes

HCPCS Code J7298: definition and clinical descriptor

HCPCS Code J7298 is the billable code for Mirena, the 52 mg levonorgestrel-releasing intrauterine system from Bayer. It’s brand-specific: Liletta, Kyleena, and Skyla each bill under their own code (J7297, J7296, and J7301). Four distinct levonorgestrel IUD HCPCS codes are active today, and selecting the wrong one for the device dispensed triggers an NDC mismatch that payers catch immediately.

This reference guide covers the full J7298 descriptor, the brand devices it covers, paired CPT and ICD-10 codes, Medicare and Medicaid reimbursement rules, and the documentation that must accompany every claim. For a broader look at HCPCS Level II coding patterns, see Pabau’s billing codes reference library.

J7298 code details at a glance

The table below summarizes the core fields coders and billers need before submitting any claim containing HCPCS Code J7298.

Verify the current descriptor wording against the CMS HCPCS overview before each billing year. CMS publishes annual updates that occasionally revise descriptor language or dosage labeling.

What drugs and devices does J7298 cover?

HCPCS Code J7298 is brand-specific: it maps only to Mirena, the 52 mg levonorgestrel-releasing IUD from Bayer. CMS dropped duration language from the J7298 descriptor in a 2017 revision, so the code is no longer tied to a labeled duration — it’s tied to the brand and dose.

Mirena (Bayer): The only device that maps to J7298. FDA-approved for up to 8 years of use for contraception and up to 5 years for heavy menstrual bleeding.

The current HCPCS descriptor is brand-specific rather than duration-based — CMS removed the duration language from J7298 in the 2017 revision. Verify Mirena’s current NDC against the CMS NDC-to-HCPCS crosswalk file before each claim, as Bayer periodically updates packaging NDC numbers.

Liletta (Medicines360, marketed by Allergan/AbbVie): A separate 52 mg levonorgestrel IUD approved for up to 8 years. Liletta does not map to J7298 — it bills under its own code, J7297.

Coders should confirm the specific Liletta NDC against the current CMS crosswalk file before submitting a J7297 claim. Practices managing device inventory can use inventory management software that ties lot numbers to dispensed NDCs automatically.

Mirena is an FDA-regulated device, and clinical claims about its approved indications must match current FDA prescribing information, not prior label versions.

Mirena should never be billed under a code intended for a different brand or dose — J7296 (Kyleena), J7297 (Liletta), or J7301 (Skyla) — regardless of how many years of use remain on the device at the time of insertion.

How to bill HCPCS J7298: step-by-step

J7298 is a supply code, not a procedure code. It reimburses the device itself. The insertion procedure is billed separately on the same claim using a paired CPT code. Submitting J7298 without the CPT insertion code is one of the most common reasons for denial on IUD claims.

1. Select the appropriate CPT code for the procedure. Choose from the CPT codes in the table below based on how and where the IUD was placed.
2. Attach J7298 as a separate line on the claim. Bill one unit per device supplied. Never bill two units for a single IUD insertion.
3. Assign the supporting ICD-10-CM diagnosis code. The diagnosis code must confirm the clinical reason for contraceptive device placement.
4. Add the National Drug Code (NDC) in the qualifier field. Report the 11-digit NDC for the specific Mirena or Liletta lot dispensed. Format: N4 qualifier + 11-digit NDC + unit of measure qualifier (UN) + quantity (1).
5. Set the place of service (POS) code. POS 11 (office) is standard for in-office insertion. POS 22 (outpatient hospital) or POS 19 (off-campus outpatient) applies when performed at a facility.
6. Submit the claim. Run eligibility and benefit verification before submission. Confirm the patient’s contraceptive benefit, any prior authorization requirement, and applicable deductible or copay structure.

Practices using claims management software can build claim templates that pre-populate J7298 with its paired CPT, default POS, and NDC qualifier fields, reducing manual entry errors on every IUD claim.

Pairing this with automated billing workflows means staff are prompted to capture the NDC at the point of dispensing rather than reconstructing it from memory at the time of claim submission.

CPT codes paired with J7298

CPT 58565 is sometimes mistaken for a hysteroscopic IUD placement code, but its actual descriptor covers hysteroscopic bilateral fallopian tube occlusion — the Essure sterilization procedure — not IUD insertion. Standard IUD placement bills under CPT 58300 regardless of whether hysteroscopic guidance is used; there is no dedicated CPT code for hysteroscopic-guided IUD placement.

Do not bill CPT 58301 (removal) and J7298 (supply) on the same date unless the procedure includes immediate reinsertion. Removal-only encounters do not use a supply code. Confirm pairing rules with the current AMA CPT codebook and payer-specific policies, as commercial payers occasionally have bundling edits that differ from Medicare guidelines.

ICD-10 diagnosis codes used with J7298

Practices serving patients with reproductive health needs can link ICD-10 code assignment to treatment records in sexual health clinic software, reducing the risk of a mismatched diagnosis on claims for hormonal contraceptive devices. Some of these same practices also bill related obstetric codes, such as CPT 76801, using that same diagnosis-to-claim linkage.

Medicare and Medicaid reimbursement for J7298

Medicare Part B covers J7298 when the levonorgestrel-releasing IUD is furnished incident to a physician service in an appropriate outpatient setting. Coverage is subject to applicable Local Coverage Determinations issued by the Medicare Administrative Contractor responsible for the practice’s jurisdiction. Verify the relevant LCD before billing, as coverage criteria and documentation requirements vary by MAC region.

Medicare reimbursement for Part B drugs follows the average sales price (ASP) methodology. The standard payment formula is ASP plus 6 percent.

Because ASP rates are updated quarterly by CMS, never publish or use a specific dollar figure for J7298 reimbursement without pulling the current quarter’s ASP pricing file from the Physician Fee Schedule lookup. A rate that was accurate last quarter may already be outdated.

Medicaid coverage for HCPCS Code J7298 is nearly universal across states for contraceptive indications, but reimbursement rates, formulary requirements, and prior authorization rules differ significantly by state program. Never apply Medicare’s ASP rate logic to Medicaid claims. Pull the applicable state Medicaid fee schedule directly from the state agency’s provider portal.

J7296 vs J7297 vs J7298 vs J7301: key differences

Four levonorgestrel IUD HCPCS codes are billed today, each tied to a specific brand and dose: J7296 (Kyleena), J7297 (Liletta), J7298 (Mirena), and J7301 (Skyla). A fifth code, J7302, is a non-brand-specific 52 mg descriptor that multiple coding references flag as deleted or inactive, so don’t rely on it as a current, reliable billable code. Deleted or replaced codes turn up elsewhere in HCPCS too — HCPCS J3370 followed the same pattern, discontinued and replaced with a successor code.

Selecting the wrong code for the brand and dose dispensed is one of the most common HCPCS billing errors in reproductive health practices. The comparison below clarifies which code applies to each device.

The critical rule: always bill the HCPCS code that matches the brand and dosage actually dispensed. A Mirena inserted but billed as J7301 will likely pass through automated edits initially but fail on audit when the NDC number is traced back to a 52 mg device.

The reverse error — billing J7298 for a 13.5 mg Skyla insertion — is a higher-dollar overpayment that triggers recoupment. Confirm the device dispensed, verify the NDC, then select the matching code.

Common billing errors with J7298 and how to avoid them

IUD supply code claims have a narrow margin for error. Payers run automated claim edits that flag unit quantity mismatches, NDC omissions, and CPT pairing issues before a human reviewer ever sees the claim. These are the denial patterns that appear most often on J7298 submissions.

• Wrong unit quantity. Bill 1 unit per device. Two units on a single-device insertion claim will be denied automatically. The only scenario where a second J7298 unit might be justified is immediate replacement of an expelled device on the same date of service, and even then, documentation must clearly support both events.
• Missing or incorrectly formatted NDC. The NDC qualifier (N4), the 11-digit NDC, the unit of measure (UN), and the quantity (1) must all appear in the correct fields. An NDC reported without the qualifier or in the wrong format causes rejection at the clearinghouse level before the claim reaches the payer.
• Wrong HCPCS code for the device supplied. A Kyleena (19.5 mg, billed under J7296) submitted as J7298 will create a brand-and-dose mismatch when the NDC is traced. Use the crosswalk-verified code for the actual device dispensed.
• Unbundled CPT and HCPCS lines. Some payers require both the CPT insertion code and J7298 on the same claim. Submitting J7298 on a claim without a paired CPT insertion code results in denial for missing procedure context.
• Place of service mismatch. If the IUD was inserted in a hospital outpatient department, POS 11 (office) is incorrect. Using the wrong POS triggers a site-of-service differential that can result in either underpayment or a technical denial.
• Absent prior authorization for commercial payers. Many commercial plans require PA for IUD supply codes. Submitting without authorization results in a denial that is difficult to overturn post-service. Verify PA requirements before insertion, not after.

OB/GYN practice management software with built-in claim scrubbing can catch unit quantity errors, missing NDC qualifiers, and POS mismatches before claims leave the practice. Catching these at the pre-submission stage costs a fraction of the time and staff effort required to work a denial.

Documentation requirements for J7298 claims

CMS and commercial payers require specific documentation to support each element of a J7298 claim. Missing documentation does not just create audit risk; it directly supports or undermines the clinical medical necessity argument if a claim is reviewed or audited. Similar documentation standards apply across other HCPCS supply codes, including HCPCS A4321.

• Brand name and NDC of the device dispensed. The medical record must identify the specific device used. “Mirena IUD inserted” is not sufficient. The entry should include “Mirena, 52 mg levonorgestrel-releasing intrauterine system, NDC [11-digit number], lot number [lot], expiration date [date] inserted.”
• Date of service. The insertion date must match the date on the claim. Date discrepancies between the clinical note and the claim form are a common audit finding.
• Clinical indication. The note must document the clinical reason for insertion. For contraceptive indications, this means documenting the patient’s choice of contraceptive method and confirmation of no contraindications. For heavy menstrual bleeding, document the HMB diagnosis and failed or declined alternatives.
• Informed consent. Document that the patient received counseling on the device, its risks, benefits, and alternatives, and that written informed consent was obtained.
• Procedure note. The clinical note must describe the insertion procedure: patient positioning, speculum placement, uterine sounding, device placement, and confirmation of proper position. For Mirena and Liletta, document thread visibility post-insertion.
• Modifier documentation (where applicable). If a modifier is applied (for example, a bilateral or multiple-procedure modifier), the record must support the modifier’s use. Modifier requirements vary by payer.

Practices using clinical documentation software with structured note templates can embed these required fields directly into their IUD insertion note template. Digital intake forms that capture consent data at the time of the appointment reduce the risk of an undocumented consent encounter surviving into a payer audit.

Medical forms best practices outline how structured form workflows reduce audit exposure across all clinical settings. Practices managing controlled substance or hormonal prescriptions alongside IUD insertions may also benefit from structured prescription management workflows that tie prescription records to the corresponding clinical note.

HIPAA-compliant documentation storage is a requirement for all clinical records supporting J7298 claims. For a practical overview of documentation and storage compliance obligations, see Pabau’s guide to HIPAA compliance for offices.

Conclusion

HCPCS Code J7298 claims fail most often for reasons that are entirely preventable: wrong dosage code, missing NDC qualifier, mismatched POS, or no paired CPT. Every one of those errors is a process fix, not a clinical one.

Pabau’s claims management software helps OB/GYN and family practice teams build claim templates that enforce correct HCPCS supply code selection, NDC formatting, and CPT pairings at the point of charge capture, before a claim reaches the payer.
