Midline catheters (MLCs) are similar to peripherally inserted central catheters (PICC lines) but they are shorter and the tip doesn’t reach the central venous system. Previous CPT coding advice was to code MLCs as PICC lines with a modifier for reduced services, but as of 2019, new instructional notes direct that MLCs are reported with the following CPT codes:

36400 Venipuncture, younger than age 3 years, necessitating the skill of a physician or other qualified health care professional, not to be used for routine venipuncture; femoral or jugular vein
36406                other vein
36410 Venipuncture, age 3 years or older, necessitating the skill of a physician or other qualified health care professional (separate procedure), for diagnostic or therapeutic purposes (not to be used for routine venipuncture)

The code descriptions state these codes can only be reported when performed by a physician or qualified health care professional (QHP) and there has been confusion on whether hospitals can report these codes when MLCs are placed by vascular nursing team. Haugen Consulting Group presented this question to Coding Clinic for HCPCS. They confirmed that since vascular nurses are specially trained and licensed, they meet the criteria for QHPs. That means that when MLCs are placed by vascular nurses in the hospital setting, the above codes can be reported. But beware: the separate procedure designation on code 36410 means it’s bundled with many other CPT codes, such as infusion therapy. Be sure to check NCCI edits before submitting code 36410 with other services.

    Hello there, thank you for this! Is the language regarding the aha coding clinic question and answer being released in one of the clinics perhaps?

      Hi Jayson –
      We submitted the question regarding midline catheters being placed by nurses to Coding Clinic for HCPCS in 2019 and received a response in October of that year. To date, Coding Clinic for HCPCS has not published that question or answer. If you would like to submit the question to Coding Clinic in an attempt to get the topic published, you can create an account and submit questions at https://www.codingclinicadvisor.com/
