What 93702 covers
This test uses bioimpedance spectroscopy to estimate extracellular fluid in body segments. It is commonly used to assess or monitor extremity swelling and lymphedema, including arm changes after breast cancer treatment. Trained clinical staff typically obtain the measurements in an outpatient clinic; a qualified clinician interprets the results under a separate code. The measurement can support lymphedema surveillance or help assess a patient with suspected or established fluid accumulation.
Report 93702 for the technical measurement, not as a substitute for the separate interpretation service. Documentation should identify the clinical reason for testing, the body area assessed, and the measurement results. Medicare treats this as a technical-component-only service. When other cardiovascular diagnostic procedures subject to the multiple-procedure reduction are reported, that reduction applies to 93702's technical component.

93702 measures extracellular fluid, commonly for lymphedema assessment or monitoring. 93701 is bioimpedance cardiovascular analysis and addresses cardiovascular measurements.
Does 93702 include the interpretation?
No. 93702 reports the technical measurement; a separate code covers interpretation.
What documentation supports reporting 93702?
Document the clinical reason for the extracellular fluid assessment, the body area measured, and the recorded results. For surveillance, identify the relevant history or condition, such as risk of or established lymphedema.
How does the multiple-procedure reduction affect 93702?
