Summary & Overview
CPT 93702: Bioimpedance Lymphedema Assessment
CPT code 93702 designates a bioimpedance spectroscopy procedure that measures tissue resistance to a mild electric current to estimate extracellular fluid volume in the limbs for early detection of lymphedema. This diagnostic modality matters nationally because early identification of lymphedema can influence clinical monitoring and noninvasive management strategies, potentially reducing morbidity associated with progressive limb swelling.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service settings for use of 93702, plus what to expect in payer coverage considerations and common billing practices. The publication summarizes how the procedure is categorized, typical clinical indications, and operational considerations for outpatient and specialty clinic settings.
The content outlines benchmarks and policy-relevant points at a national level, including common modifier usage patterns and payer mix considerations where available. Data not provided in the input (such as specific reimbursement rates, associated ICD-10 codes, and provider taxonomies) are noted as unavailable; readers will gain a clear, practical understanding of the code’s clinical purpose and billing context for programmatic and administrative decision-making.
Billing Code Overview
CPT code 93702 describes a noninvasive bioimpedance assessment that measures tissue resistance to a mild electric current to determine the volume of extracellular fluid in the limbs. The procedure is used to detect early lymphedema by quantifying fluid accumulation in tissue spaces outside of cells, enabling early identification of abnormal fluid shifts.
Service type: Diagnostic test — bioimpedance spectroscopy for lymphedema assessment
Typical site of service: Outpatient clinic, specialty lymphedema or vascular clinic, or rehabilitation/physical therapy setting
Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.
Clinical & Coding Specifications
Clinical Context
A 56-year-old female breast cancer survivor presents to an outpatient vascular/lymphatic clinic for baseline and surveillance evaluation for lymphedema following axillary lymph node dissection and radiation therapy performed 3 months prior. The provider obtains a focused history of limb heaviness, tightness, prior infections, and recent weight change. The patient is asked to remove clothing from the limb(s) to be evaluated and positioned supine or seated. Skin integrity and wounds are inspected. Electrodes or electrode pads are applied to standardized locations on the upper or lower extremities. The provider or trained technologist performs bioimpedance spectroscopy using the 93702 procedure to measure tissue resistance and estimate extracellular fluid volume. Results are compared to baseline or contralateral limb values to detect early extracellular fluid accumulation consistent with lymphedema. Findings are documented in the medical record with relevant measurements, interpretation, and plan for surveillance, compression, referral to lymphedema therapy, or other interventions as appropriate.
Coding Specifications
| Modifier | Description | When to Use |
