CPT Code: 99202 ICD-10 Code: K52.9

QUESTION

27-year-old established female patient presents the urgent care clinic during normal working hours complaining of nausea, vomiting and lethargy. After a detailed history, expanded problem-focused examination and MDM of low complexity, the provider diagnoses the patient with acute gastroenteritis. What is the CPT code and the ICD-10 code?

ANSWER

CPT Code: 99202 ICD-10 Code: K52.9

For the scenario described, the appropriate CPT code and ICD-10 code for the diagnosis of acute gastroenteritis are as follows:

CPT Code: 99203

ICD-10 Code: K52.9

Let’s break down the rationale for these code selections:

CPT Code 99203: This code represents a “New Patient Office or Other Outpatient Visit” with a detailed history, expanded problem-focused examination, and medical decision-making of low complexity. It is used when a new patient seeks evaluation and management services in an outpatient setting, such as an urgent care clinic. In this case, the patient is an established female, but the visit level corresponds to the complexity of the encounter, which includes assessing symptoms of nausea, vomiting, and lethargy, indicative of a gastrointestinal issue.

ICD-10 Code K52.9: This code corresponds to “Noninfective Gastroenteritis and Colitis, Unspecified.” Since the provider diagnosed the patient with acute gastroenteritis, which is a form of gastroenteritis, the most appropriate ICD-10 code to use is K52.9. This code is used when the specific cause or pathogen responsible for the gastroenteritis is unspecified.

It’s important to ensure accurate coding for medical billing and record-keeping purposes, and these codes reflect the clinical encounter and diagnosis described in the scenario. However, for precise coding and billing, healthcare providers and institutions should always consult official coding guidelines and any specific payer requirements in effect.
