2024 ICD-10-CM Diagnosis Code E66.3

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Body mass index 25-29 - overweight
• Fetal disorder due to maternal overweight
• High body weight
• Increased body mass index
• Increased body mass index
• Overweight
• Overweight in adulthood with body mass index of 25 or more but less than 30
• Overweight in childhood
• Peripheral neuropathy due to overweight
• Speech delay
• X-linked intellectual disability, short stature, overweight syndrome

Clinical Information

• Overweight

  a status with body weight that is above certain standards. in the scale of body mass index, overweight is defined as having a bmi of 25.0-29.9 kg/m2. overweight may or may not be due to increases in body fat (adipose tissue), hence overweight does not equal "over fat".

• Pediatric Obesity

  body mass index in children (ages 2-12) and in adolescents (ages 13-18) that is grossly above the recommended cut-off for a specific age and sex. for infants less than 2 years of age, obesity is determined based on standard weight-for-length percentile measures.

• Body Mass Index

  an indicator of body density as determined by the relationship of body weight to body height. bmi=weight (kg)/height squared (m2). bmi correlates with body fat (adipose tissue). their relationship varies with age and gender. for adults, bmi falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese).

E66.3 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
640	MISCELLANEOUS DISORDERS OF NUTRITION, METABOLISM, FLUIDS AND ELECTROLYTES WITH MCC	10	1.3152
641	MISCELLANEOUS DISORDERS OF NUTRITION, METABOLISM, FLUIDS AND ELECTROLYTES WITHOUT MCC	10	0.7814

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

Body Weight

Do you know if your current weight is healthy? "Underweight", "normal", "overweight", and "obese" are all labels for ranges of weight. Obese and overweight mean that your weight is greater than it should be for your health. Underweight means that it is lower than it should be for your health. Your healthy body weight depends on your sex and height. For children, it also depends on your age.

A sudden, unexpected change in weight can be a sign of a medical problem. Causes for sudden weight loss can include:

• Thyroid problems
• Cancer
• Infectious diseases
• Digestive diseases
• Certain medicines

Sudden weight gain can be due to medicines, thyroid problems, heart failure, and kidney disease.

Good nutrition and exercise can help in losing weight. Eating extra calories within a well-balanced diet and treating any underlying medical problems can help to add weight.
