A hospital outpatient procedure is performed on the left side only, and the CPT/HCPCS code does not inherently describe laterality. Which modifier approach is appropriate?
Select an answer to reveal the explanation.
Short Explanation
When the code itself is silent about left versus right, LT and RT are the name tags that say which side was done. If the chart says left, hang the left tag—do not invent bilaterality.
Full Explanation
Laterality modifiers such as LT and RT identify the side of the body for CPT/HCPCS codes that are not inherently lateralized. Documentation of the operative side drives modifier selection. These modifiers should not be used to imply bilaterality, replace a true bilateral code/modifier pathway, or substitute for accurate unit reporting.
