TL;DR

HCPCS J7042 is the Level II code for 5% dextrose/normal saline (500 ml = 1 unit), billed per 500 ML. The Medicare Part B ASP payment limit for October 2026 is $1.265 per billing unit, up 4.1% from July 2026. The practitioner MUE allows up to 6 units per date of service (MAI 3). Under OPPS it carries status indicator N. J7042 is billed in units of 500 ML; the quantity administered, the NDC package and the units on the claim must reconcile, which is the check that prevents CARC 16 and 151 returns on this line. The ASP crosswalk maps 6 NDCs to it, sold as Dextrose-NaCl by B. Braun Medical Inc., ICu Medical Inc., FreseniUS Kabi USA, LLC. No current Billing and Coding Article lists J7042, so coverage follows the FDA label, compendia and any applicable NCD.

NCCI edits and add-on relationships

No active practitioner PTP pair lists J7042 as a column-1 or column-2 code in v323r0. Drug supply codes are rarely bundled; the administration codes billed with them are where PTP edits usually apply.

J7042 is neither an add-on code nor a designated primary code in the 2026 Q4 NCCI add-on edit file.

Medicare coverage articles

No current Billing and Coding Article lists J7042 in its HCPCS table. Coverage then follows the drug's FDA label, compendia and any National Coverage Determination; check the Medicare Coverage Database before administering off-label.

Hospital outpatient (OPPS) status

In the July 2026 OPPS Addendum B, J7042 carries status indicator N. Status N means payment is packaged into the associated procedure and no separate OPPS payment is made.
