1. What is Newborn Percentage Weight Loss?

The percentage weight loss calculation measures how much weight a newborn has lost compared to their birth weight. This is important for ICD-10 coding and clinical assessment of neonatal health.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{Birth Weight} \) — Newborn's weight at birth in kilograms
• \( \text{Current Weight} \) — Newborn's current weight in kilograms

Explanation: The formula calculates what percentage of the original birth weight has been lost.

3. Importance of Weight Loss Calculation

Details: Monitoring newborn weight loss is crucial for identifying excessive weight loss which may indicate feeding problems, dehydration, or other health issues requiring intervention.

4. Using the Calculator

Tips: Enter birth weight and current weight in kilograms. Both values must be valid (weight > 0, current weight ≤ birth weight).

5. Frequently Asked Questions (FAQ)

Q1: What is normal newborn weight loss?
A: Most newborns lose 5-7% of birth weight in first few days, with 10% often considered the upper limit of normal.

Q2: When should I be concerned about weight loss?
A: Weight loss >10% or continued weight loss beyond 3-4 days may require evaluation of feeding and hydration.

Q3: How often should newborns be weighed?
A: Typically at birth, 24 hours, and 48 hours after birth, then as needed based on clinical assessment.

Q4: What ICD-10 codes relate to newborn weight loss?
A: Common codes include P92.0 (Regurgitation and rumination of newborn), P92.1 (Slow feeding of newborn), and P92.5 (Neonatal difficulty in feeding).

Q5: Does this calculator account for gestational age?
A: No, the calculator provides a simple percentage calculation. Clinical interpretation should consider gestational age and other factors.
