What nausea ICD codes can I use?

If you’re looking for nausea ICD codes, we’d like you to know that there are only two that you can use specifically for it. Here they are:

  1. R11.0 - Nausea: This ICD-10 code is meant to be used on a patient confirmed to be nauseated for whatever reason.
  2. R11.2 - Nausea with vomiting, unspecified: This ICD-10 code is meant to be used on a patient confirmed to be nauseated, and because they are nauseated, they are vomiting. What is unspecified is the cause of the nausea and vomiting. It may also be referring to the type of vomiting being unspecified.

Please note that these ICD codes are not valid as principal diagnoses because nausea is a symptom of an underlying problem/cause.

Are both of these nausea ICD codes billable?

Yes. While they are not valid as principal diagnoses, they are valid in general and billable.

Clinical information about nausea:

The term "nausea" describes the sensation of being sick to your stomach. We experience strange, unsettling, and unnerving feelings in the stomach and the back of our throats that make us feel lightheaded, dizzy, unusually disgusted, and, in more severe cases, susceptible to fainting.

You might feel like falling if you're feeling queasy while moving. Even if you know what you're eating is delicious, you might have trouble swallowing it if you're feeling queasy while you're eating.

Even if you don't have anything to throw up, nausea will contribute to the feeling or desire to do so. You might do that if you have anything in your stomach. Vomiting often occurs along with nausea.

As mentioned, nausea is a sign of an underlying illness or issue. Numerous factors, including pregnancy, using certain drugs, excessive alcohol consumption, motion sickness, vertigo, migraines, and even food poisoning, can result in nausea.

Synonyms include:

  • Functional nausea
  • Nausea
  • Nausea present
  • Postoperative nausea
  • Chemotherapy-induced nausea and vomiting
  • Decreased nausea and vomiting
  • Drug-induced nausea and vomiting
  • Increased nausea and vomiting
  • Intractable nausea and vomiting
  • Nausea and vomiting following administration of anesthetic agent

Commonly asked questions

Are there unbillable nausea ICD codes?

Yes. There is another one, but not only is it unbillable, but it’s also invalid. So, stick with the two we mentioned above.

The aforementioned factors that cause nausea are predictable. What "serious" factors can cause nausea?

Some serious conditions that can cause nausea include traumatic brain injuries, concussions, brain tumors, blockages/obstructions in the blood, and even meningitis.

How is nausea treated?

Depending on what's causing it, yes. To fully treat nausea, the underlying cause must be addressed. While the nausea is still present, resting, eating slowly, choosing foods that are simple to chew, and drinking plenty of water can all help.
