1. Review of Medical Record

• Begin by reviewing the resident's medical records for any documented weight measurements within the last 30 days and the last 180 days. Pay special attention to any physician, nurse practitioner, physician assistant, or clinical nurse specialist documentation that might provide insight into unintentional or intentional weight loss.

2. Understanding the Definition

3. Coding Instructions

• K0300A (Loss of 5% or more in the last month):
  • Code "1" if there's documentation of a loss of 5% or more in weight in the last 30 days.
  • Code "0" if this does not apply.
• K0300B (Loss of 10% or more in the last 6 months):
  • Code "1" if there's documentation of a loss of 10% or more in weight in the last 180 days.

• Ensure to account for any medical conditions or treatments that may contribute to weight loss, distinguishing between intentional and unintentional weight loss.
