It is the bundled column-2 code in 1548 NCCI pairs, most often with 0345T, 0419T, 0420T. No current Billing and Coding Article lists J0670, so coverage follows the FDA label, compendia and any applicable NCD.

NCCI edits and add-on relationships

In the practitioner PTP file v323r0 (effective October 1, 2026), J0670 is the column-2 code in 1548 active pairs, 100% of which allow a modifier (indicator 1), and the column-1 code in 0. 141 historical pairs have been deleted over time. CMS's most frequent rationale: Misuse of Column Two code with Column One code.

When billed with these column-1 codes, J0670 is the bundled component unless the pair allows a modifier and the documentation supports a distinct service.

Frequently asked questions — HCPCS J0670

What does HCPCS code J0670 describe?

J0670 is defined by CMS as "Injection, mepivacaine hydrochloride, per 10 ml". Each billing unit represents 10 ML, so the units reported on the claim must equal the dose administered divided by that unit.

What is the Medicare reimbursement for J0670 in October 2026?

The ASP-based payment limit is $4.367 per 10 ML, with 20% beneficiary coinsurance. Medicare Administrative Contractors apply this limit; commercial payers use their own fee schedules. The July 2026 limit was $4.147.

How many units of J0670 can be billed per day?

The practitioner Medically Unlikely Edit is 10 units per date of service with adjudication indicator 3 (3 Date of Service Edit: Clinical). MAI 3 edits can be appealed with documentation that the units were medically reasonable. CMS cites "Clinical: Data" as the rationale.

Which NDCs map to J0670?

The October 2026 ASP crosswalk lists 11 NDCs from 3 labelers: Polocaine (A-S Medication Solutions); Polocaine-Mpf (HF Acquisition Co. LLC, DBA HealthFirst); Polocaine - Mpf (HF Acquisition Co. LLC, DBA HealthFirst); Polocaine (HF Acquisition Co. LLC, DBA HealthFirst). For example NDC 50090-4408-00 is a 50 package equal to 5 billing units. The crosswalk's billing-units-per-package figure converts each package into J0670 units.

Does J0670 have NCCI bundling edits?

In the v323r0 practitioner PTP file, J0670 appears as the column-2 (bundled) code in 1548 active pairs and as the column-1 code in 0. 100% of the column-2 pairs allow a modifier (indicator 1). The most frequent column-1 partners are 0345T, 0419T, 0420T, 0446T, 0447T, and CMS's leading rationale is "Misuse of Column Two code with Column One code".
