Gastric Antrum Neurostimulation (March 2007)
March 2007 pages 4-5 Coding Communication:Gastric Antrum Neurostimulation Gastric Antrum Neurostimulation What is gastric antrum neurostimulation? Gastric antrum neurostimulation is a treatment for patients with gastroparesis that involves electrical stimulation of the stomach to improve gastric motility. Due to the fact that implantation of these electrode devices may require multiple procedures to complete the treatment, separate codes are listed in the CPT codebook to identify the placement of the pulse generator device (64590), or the revision or removal of the implanted devices (64595). Implantation of the electrodes which are attached to the pulse generator device is similar to electrode...

Article Overview
This March 2007 CPT Assistant article explains coding communication for gastric antrum neurostimulation, a procedure used in the management of gastroparesis and related conditions. It is aimed at coders, billers, and clinical documentation staff who need to understand the scope of the procedure, the CPT and Category III code family associated with gastric neurostimulation, and how the article organizes laparoscopic and open surgical reporting guidance. The article also discusses related procedure categories, the context for the new codes introduced in 2007, and references to other services that are not reported separately in the scenarios described.
Why This Topic Matters
Gastric neurostimulation coding involves multiple related procedures and code families, so accurate article interpretation helps support consistent reporting and better documentation review. It also clarifies how this technology was being represented in CPT coding guidance at the time.
