In simple words: This code covers a special device placed under the skin that helps control movement problems. It sends tiny electrical signals to the brain to help reduce tremors and other symptoms.

This code represents the supply of a high-frequency, rechargeable neurostimulator generator used to stimulate nerves in the brain. It's placed under the skin, typically below the collarbone or in the abdomen, and transmits electrical signals to implanted electrodes that target specific brain areas to alleviate symptoms associated with conditions like Parkinson's disease, tremors, or dystonia.

Example 1: A patient with Parkinson's disease experiences debilitating tremors that are unresponsive to medication. Implantation of a neurostimulator generator (C1820) is recommended to manage the tremors., A patient with essential tremor undergoes implantation of a C1820 neurostimulator generator to alleviate the tremor and improve their quality of life., A patient with dystonia experiences involuntary muscle contractions that interfere with their daily activities. A neurostimulator generator (C1820) is implanted to help reduce the severity of the dystonia.

Documentation should include the diagnosis justifying the medical necessity of the neurostimulator, the type of generator implanted (C1820), the surgical report detailing the implantation procedure, and subsequent programming notes.

** While the pass-through payment status for device category codes like C1820 may have expired, hospitals are still required to report these codes on claims when used in conjunction with procedures billed under the OPPS. This is to ensure accurate device tracking and appropriate payment for the procedures.
