Summary & Overview
HCPCS G9708: Bilateral Mastectomy Status
HCPCS Level II code G9708 identifies women who have undergone a bilateral mastectomy, have a documented history of bilateral mastectomy, or have evidence of right and left unilateral mastectomies. Nationally, a code for bilateral mastectomy status is important for care coordination, cancer surveillance, reconstructive planning, and payment adjudication tied to prior surgical history. It supports accurate problem lists, eligibility for reconstruction or prosthetic services, and can affect quality measurement and care pathways for breast cancer survivors.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise breakdown of the clinical intent of the code, the primary service contexts where it is recorded, and expected uses in administrative and clinical workflows. The publication highlights common modifiers associated with surgical status coding, typical sites of service, and notes where input data were unavailable.
This summary provides national-level context rather than jurisdiction-specific guidance. Data not available in the input are identified as such; the focus remains on helping clinicians, coders, and administrators understand the role of G9708 in documenting bilateral mastectomy status and related administrative processes.
Billing Code Overview
HCPCS Level II code G9708 denotes women who have had a bilateral mastectomy, have a history of a bilateral mastectomy, or have evidence of both right and left unilateral mastectomies. This code is used to identify patients with prior bilateral breast removal for clinical, quality measurement, or administrative purposes.
Service type: Surgical history / Procedure status classification
Typical site of service: Hospital inpatient or outpatient surgical settings, ambulatory surgery centers, and specialty clinics where surgical history is reviewed or documented
Clinical & Coding Specifications
Clinical Context
A 58-year-old woman with a prior diagnosis of invasive ductal carcinoma underwent bilateral mastectomy one year ago and presents for routine postoperative surveillance and discussion of reconstructive options. Her electronic medical record documents both right and left mastectomy procedures with operative reports confirming removal of breast tissue bilaterally. The clinical workflow includes review of prior surgical history, physical exam focused on chest wall and flap integrity, assessment for lymphedema or post‑mastectomy complications, discussion of reconstruction or prosthetic fitting, and documentation of surgical history for billing and quality reporting. Administrative staff verify eligibility and coverage, and coding staff assign the appropriate HCPCS Level II code G9708 to indicate a current or historical bilateral mastectomy. Common encounters include visits to breast surgery clinics, plastic surgery consults for reconstruction, oncology survivorship visits, and durable medical equipment referrals for external prostheses.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typically required for the service and documentation supports increased complexity related to post‑mastectomy care or complicated reconstruction planning. |
