The Impact of e66.01 and e66.3 Codes on Obesity Management and Billing

e66 Codes & Obesity Billing Impac

Obesity management and medical billing are intricately linked through specific codes like e66.01 and e66.3. These codes not only define the scope and severity of obesity but also directly influence treatment plans, billing processes, and insurance coverage. Understanding these codes is crucial for healthcare providers and medical billers alike. This blog delves into the significance of these codes and their impact on the healthcare industry.

Understanding the e66.01 Diagnosis Code for Morbid Obesity

The e66.01 diagnosis code is pivotal in the medical world, serving as a key identifier for morbid obesity. This section explores its clinical and billing implications.

Is the E66.01 billable?

Yes, the E66.01 ICD-10 code is billable and can be used to designate a patient for reimbursement purposes.

E66.01 synonyms include:

  • Morbid obesity
  • Obese class III
  • Severe obesity

Other ICD-10 codes commonly used for obesity:

E66 – Overweight and obesity

E66.0 – Obesity due to excess calories

E66.09 – Other obesity due to excess calories

E66.1 – Drug-induced obesity

E66.2 – Morbid (severe) obesity with alveolar hypoventilation

E66.3 – Overweight

E66.8 – Other obesity

E66.9 – Obesity, unspecified Below is information from the ICD-10-CM Official Guidelines for Coding and Reporting

Sample ICD-10-CM Codes for Overweight and Obesity

Code Description
E66.01 Morbid (severe) obesity due to excess calories
E66.09 Other obesity due to excess calories
E66.1 Drug-induced obesity
E66.2 Morbid (severe) obesity with alveolar hypoventilation
E66.3 Overweight
E66.8 Other obesity

Coding Obesity and Morbid Obesity

An obesity diagnosis is based on the clinician’s diagnostic statement that the member has the condition. An additional code should be used to identify BMI, if known.

According to ICD-10-CM guidelines, the clinician should document that the member is overweight, obese or morbidly obese. Coders must use the clinician’s statement to assign the corresponding E66 code. A coder can’t code a weight diagnosis based on BMI calculations, lab values or other measurements.

Coders should use BMI codes only when there is an associated, reportable weight diagnosis, such as obesity. A clinician other than the patient’s provider, such as a nurse or dietician, may record BMI. However, BMI shouldn’t be coded unless the clinician documents the associated weight diagnosis.

Sample ICD-10-CM Codes for BMI


BMI 20-29, adult


BMI 30-39, adult


BMI 40 or greater, adult


BMI, pediatric

BMI is a screening tool and not an indicator of health.

  • BMI adult codes are for people age 20 years and older
  • BMI pediatric codes are for people ages 2 to 19 years
  • Don’t code BMI in pregnancy
