Tissue transfers, such as an omental flap, are considered investigational.
Reverse lymphatic mapping used as part of lymphatic surgical or liposuction procedures is considered investigational.

This section addresses coverage determinations for prophylactic lymphatic physiologic microsurgery intended to prevent post-breast cancer lymphedema (BCRL), as well as physiologic microsurgery and other surgical procedures used to treat lymphedema. Prophylactic lymphovenous bypass (LVB) or lymphovenous anastomosis (LVA), also known as the lymphatic microsurgical preventive healing approach (LYMPHA), is covered only when the specified medical-necessity criteria are met. Other prophylactic lymphatic physiologic microsurgery is not medically necessary, and procedures used to treat lymphedema are experimental, investigational, or investigational as described below.

Prophylactic LVB/LVA to prevent BCRL is medically necessary when the member is undergoing axillary lymph node dissection (ALND) for breast cancer, has planned regional nodal irradiation, and is overweight with a BMI of at least 25. All three conditions must be met. When these criteria are not met, prophylactic LVB/LVA is considered not medically necessary.

Prophylactic lymphatic physiologic microsurgery other than LVB/LVA—including lymphaticolymphatic bypass, autologous lymph node transplantation, and vascularized lymph node transfer—to prevent BCRL is considered not medically necessary. Lymphatic physiologic microsurgery for treatment of lymphedema—including lymphaticolymphatic bypass, LVB, LVA, autologous lymph node transplantation, and vascularized lymph node transfer—is considered experimental and investigational. Excisional procedures such as debulking and liposuction/lipectomy are experimental and investigational; tissue transfers such as an omental flap and reverse lymphatic mapping used as part of lymphatic surgical or liposuction procedures are investigational.

Authorization, Documentation, and Review Actions

Note

Apply Policy Criteria

Apply the criteria under the Policy section of this medical policy for Commercial, Medicaid—BeHealthy, and Medicare members. Medicaid—BeHealthy has no MassHealth guidelines for the surgical procedures listed in this policy, and Medicare has no applicable NCD or LCD.

Commercial: Refer to the criteria under the Policy section.
Medicaid—BeHealthy: Refer to the criteria under the Policy section; no MassHealth guidelines apply to the listed surgical procedures.
Medicare: Refer to the criteria under the Policy section; no Medicare NCD or LCD applies to the listed surgical procedures.

Prior Authorization

Codes Requiring Prior Authorization

Prior authorization is required for the listed excisional, suction-assisted lipectomy, lymphovenous bypass, and associated unlisted procedure codes. Verify authorization requirements before submitting these services.

Excision of excessive skin and subcutaneous tissue, including lipectomy: CPT 15830, 15832–15839 — prior authorization required.

Condition and Treatment Context

Lymphedema is fluid accumulation caused by disruption of lymphatic drainage. It may be primary or secondary to conditions such as cancer treatment or trauma. Management may include self-care, compression, manual lymphatic drainage, complete decongestive therapy, and pneumatic compression. Surgical options include reductive procedures for advanced disease and physiologic microsurgery, such as lymphovenous bypass or vascularized lymph node transfer; this policy distinguishes prophylactic LVB/LVA from procedures used to treat established lymphedema.

Procedure and Terminology Definitions

Lymphovenous bypass or lymphaticovenular anastomosis

TechniqueIdentifies patent residual lymphatic channels and connects them to a recipient venule.

AnastomosisCreates a lymphatic-to-venule connection using microsurgical technique.

PurposeAllows lymphatic fluid outflow and may improve lymphedema.

Vascularized lymph node transplant, lymph node transfer, or autologous lymph node transfer

TreatmentAn advanced microsurgical treatment for lymphedema involving removal of lymph nodes from another area of the body.

TransferTransfers the lymph nodes to areas where lymph nodes are absent due to cancer treatment.

Prior Authorization

Prior Authorization Required for Prophylactic LYMPHA

Prophylactic lymphovenous bypass (LVB) or lymphovenous anastomosis (LVA), also called LYMPHA, is covered with prior authorization for all lines of business.

Applies to Commercial, Medicaid, and Medicare lines of business.
CPT 1019T represents lymphovenous bypass, including robotic assistance, when performed, per extremity.

Documentation Required

Submit Evidence Supporting Medical Necessity

The treating physician or primary care provider must submit clinical evidence to Health New England demonstrating that the patient meets the criteria for the requested treatment, testing, or surgical procedure.

Submit the clinical evidence with the prior authorization request.
Documentation must support that the applicable medical-necessity criteria are met.

Denial Risk

Prophylactic LVB/LVA Criteria Not Met

Prophylactic LVB/LVA to prevent post-breast-cancer lymphedema is not medically necessary when the specified criteria are not met.

The member is undergoing axillary lymph node dissection (ALND) for breast cancer.
The member has planned regional nodal irradiation.
The member is overweight (BMI ≥ 25).
All three criteria must be met for the prophylactic LVB/LVA procedure to be considered medically necessary.

Denial Risk

Other Prophylactic Microsurgery

Other prophylactic lymphatic physiologic microsurgery to prevent post-breast-cancer lymphedema is not medically necessary.

Examples include lymphaticolymphatic bypass, autologous lymph node transplantation, and vascularized lymph node transfer.

Denial Risk

Therapeutic Physiologic Microsurgery

Lymphatic physiologic microsurgery for treatment of established lymphedema is considered experimental and investigational.

Reverse lymphatic mapping used as part of lymphatic surgical or liposuction procedures is considered investigational.

Coverage is subject to the member’s benefit plan and applicable coverage requirements.

Documentation Required

Missing Clinical Evidence

Without the required clinical documentation and information, Health New England cannot properly review a prior authorization request. Missing evidence may prevent a determination that the applicable criteria are met and may result in denial or inability to authorize the service.

The treating physician or primary care provider must submit evidence supporting medical necessity.
Submit documentation showing how the patient meets the applicable policy criteria.
Benefit-plan exclusions and applicable legal requirements may affect coverage even when medical-necessity criteria are met.

PurposeThe transferred nodes are intended to improve lymph flow and reduce swelling, tightness, and pain.

Lymphatic microsurgical preventive healing approach or LYMPHA

ProcedureA surgical procedure performed at the time of lymph node dissection.

TimingPerformed during lymph node dissection in high-risk patients.

PurposeIntended to prevent lymphedema.
