Obesity ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
E66.9 | Obesity, unspecified | ICD-10-CM |
E66.01 | Morbid (severe) obesity due to excess calories | ICD-10-CM |
E66.3 | Overweight | ICD-10-CM |
Z68.30 | Body mass index 30.0-30.9, adult | ICD-10-CM |
Z68.41 | Body mass index 40.0-44.9, adult | ICD-10-CM |
Z71.3 | Dietary counseling and surveillance | ICD-10-CM |
Code the documented weight diagnosis first: overweight, obesity, or severe obesity. Add the specific BMI Z68.- code when BMI is documented and payer rules allow it. Do not code BMI alone without the associated clinical diagnosis.
“Weight-management visit. BMI 42.1 with hypertension and knee pain limiting exercise. Assessment: severe obesity due to excess calories. Discussed nutrition plan, GLP-1 eligibility, and referral to dietitian.”
Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
AI suggestions are not a substitute for clinician judgment, payer rules, local coding policy, or the official code set.
FAQ
Can I code BMI without obesity?
BMI Z68.- codes are secondary context codes and generally require the associated weight diagnosis to be documented.
When is E66.01 appropriate?
Use E66.01 when severe or morbid obesity due to excess calories is documented, often with BMI 40 or higher depending on clinical and payer context.
Can AI extract BMI and counseling facts?
Notat extracts BMI, obesity diagnosis, comorbidities, and counseling decisions as clinical facts, then suggests diagnosis and BMI codes with supporting evidence.
