What should a Medical Practice know about Obesity Counselling & MNT Billing?

Obesity is an ongoing epidemic affecting adults and children. Obesity leads to various health issues. The state of affairs has been worsened with prevalence of COVID.

Providers manage obesity and related conditions through therapies and counseling. It is even more integral for an internist or a family physician who sees these kinds of cases on regular basis.

In this article, highlighting simple services to improve obese patients' health.

Where the term ‘over-weight’ or ‘obese’ is used?

Obesity and overweight have different clinical and coding implications. A patient is supposed ‘over-weight’ or ‘obese’ on the basis of their BMI (body mass Index). Higher BMI values indicate obesity, important for coders to understand. Specifically, BMI 25-30 is overweight, 35.0 is obese.

This can all be better understood by the ICD-10 codes assigned to each of the BMI ranges.

Some Guidelines:

  • Use these BMI related ICD-10 codes when billing obesity counselling services.
  • ICD-10 codes support medical necessity and reimbursement.
  • Look for medical notes, when not sure about what billable ICD-10 to choose from.
  • BMI is documented during vital signs.
  • BMI can be calculated from documented weight and height.
  • Use E66.09 – E66.9 for better explaining other causes of obesity in your claims.
