Underweight is considered a BMI of 18.4 or lower. A BMI of normal weight is any number between 18.5 and 24.9. The overweight range is between 25 and 29.9, with anything above that being considered obese. Maintaining a low BMI is important for normal health, growth and functioning of your body.
The study results suggest that being underweight increases risk for osteoporosis. Women with low BMIs are at increased risk for amenorrhea, which is an absence of menses, and other menstrual cycle dysfunctions. Irregular or missed menstrual cycles may be an indicator of anovulation, or that you aren’t ovulating.
Standard BMI Ranges. For adults aged 20 and older, a BMI less than 18.5 is low, and puts you in the danger zone. A number between 18.5 and 24.9 is a normal BMI; a BMI between 25 to 29.9 is considered overweight and a BMI of 30 and higher is considered obesity. However, exceptions do exist for all these ranges.

Anorexia nervosa is a differential diagnosis in underweight patients, especially in young underweight women.
Report the primary diagnosis as E66. 01, then an additional secondary diagnosis for body mass index (BMI) and a third diagnosis for the comorbidities as appropriate.

An underweight person is a person whose body weight is considered too low to be healthy.
18.5below 18.5 – you're in the underweight range. between 18.5 and 24.9 – you're in the healthy weight range. between 25 and 29.9 – you're in the overweight range. between 30 and 39.9 – you're in the obese range.
ICD-10 code E66. 01 for Morbid (severe) obesity due to excess calories is a medical classification as listed by WHO under the range - Endocrine, nutritional and metabolic diseases .
19, however, states that a BMI documented by a dietician cannot be coded unless the provider documents a nutritionally-related diagnosis, such as obesity, overweight, underweight, or malnutrition, Kennedy says. These affirm that the BMI code meets the guidelines' definition of an additional diagnosis.
Other specified counselingICD-10 code Z71. 89 for Other specified counseling is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
Code assignment is not based on clinical criteria used by the provider to establish the diagnosis.”. This guidance is important since there are some situations where a patient can have severe or morbid obesity with a BMI of 35-39.9 due to co-existing comorbid conditions.
Coding professionals must remember that BMI codes were never intended to be used as standalone codes.
Code the provider diagnosis, regardless of documented BMI. The BMI is a screening tool. If a BMI falls into the morbid obesity range, but the provider documents obesity, abstract obesity. Conversely, if the BMI falls into the range for obesity, but the provider documents morbid obesity, abstract morbid obesity.
Body mass index (BMI) is a computation based on a patient’s weight and height. This calculation is used as a screening tool for providers. In most electronic health records, a patient’s BMI is auto-generated into their vitals data from a height and weight measurement obtained at the beginning of the visit.#N#BMI screening can be reported as a quality measure (Quality ID #128) in the Merit-based Incentive Payment System (MIPS). This measure identifies the percentage of adult patients with a BMI outside of normal parameters, for whom a follow-up plan is documented. For MIPS, performance may or may not be met by reporting one of the following HCPCS Level II codes:#N#G8417 BMI is documented above normal parameters and a follow-up plan is documented#N#G8418 BMI is documented below normal parameters and a follow-up plan is documented#N#G8419 BMI documented outside normal parameters, no follow-up plan documented, no reason given#N#G8420 BMI is documented within normal parameters and no follow-up plan is required#N#G8421 BMI not documented and no reason is given#N#G8422 BMI not documented, documentation the patient is not eligible for BMI calculation#N#G8938 BMI is documented as being outside of normal limits, follow-up plan is not documented, documentation the patient is not eligible#N#G9716 BMI is documented as being outside of normal limits, follow-up plan is not completed for documented reason#N#Note: Both denominator and numerator criteria must be met. Refer to MIPS quality measure specifications for requirements, available at qpp.cms.gov.
Morbid obesity is weighted as the rough equivalent of cerebral palsy or chronic pancreatitis in risk and resource utilization. Remember to pay attention to the nuances of correct coding of morbid obesity to receive appropriate MIPS bonuses and proper risk adjustment reimbursement.
All weight diagnoses are not treated equal under MIPS and risk adjustment. Overweight and obese diagnoses do not affect quality scores or risk adjustment payment. Morbid obesity, however, affects both MIPS and risk adjustment calculations.
A diagnosis not ed in the history of present illness (HPI), assessment, or discharge summary suffices without other support. Always report BMI documented with other weight-related diagnoses when they are supported and abstracted from the medical record. Do not report a diagnosis of overweight without additional support.
G8938 BMI is documented as being outside of normal limits, follow-up plan is not documented, documentation the patient is not eligible. G9716 BMI is documented as being outside of normal limits, follow-up plan is not completed for documented reason. Note: Both denominator and numerator criteria must be met.
8. Comorbidities do not change a documented diagnosis of obesity into morbid obesity. Comorbidities — including obstructive sleep apnea, hypertension, and diabetes — do not affect the weight-related diagnosis from the provider. The provider will consider the comorbidities when determining the weight diagnosis.
