CGM Monthly Supply Allowance, Non-Adjunctive — HCPCS A4239

Continuous Glucose Monitor Supplies, Monthly Supply Allowance — CGM Sensors & Supplies | HCPCS A4239

This monthly supply allowance for non-adjunctive Continuous Glucose Monitor (CGM) systems covers the recurring sensors and related supplies needed to keep glucose monitoring running without interruption. Billed under HCPCS code A4239, this allowance includes all disposable components required for one month of continuous use with a non-adjunctive, non-implanted CGM device (HCPCS E2103).

CGM sensors have a limited wear life and must be replaced on schedule to maintain accurate, uninterrupted readings. With VELO Healthcare’s managed supply program, replacement sensors arrive before the current ones expire — so patients never face a gap in glucose visibility, alerts, or treatment data.

HSA & FSA Eligible

Design Features

Commonly Prescribed For

• Ongoing CGM use with a non-adjunctive device (E2103)
• Diabetes management on insulin (Type 1 & Type 2)
• History of problematic hypoglycemia
• Hypoglycemia unawareness
• Intensive insulin therapy requiring continuous glucose data

How It Works

Each CGM sensor measures glucose continuously for its manufacturer-specified wear period, then must be replaced with a fresh sensor to maintain accuracy and uninterrupted data. The A4239 monthly allowance covers the full set of supplies needed for that replacement cycle. Under VELO Healthcare’s managed program, your resupply is scheduled automatically — insurance is re-verified, the order is processed, and new sensors ship before your current supply runs out. Patients simply apply the new sensor, pair it with their receiver or display device, and monitoring continues seamlessly.

Insurance & Billing

HCPCS Code: A4239 — Supply allowance for non-adjunctive, non-implanted continuous glucose monitor, one month supply.

VELO Healthcare bills Medicare and most major insurance plans directly with a valid physician’s order.

Billing notes: A4239 covers monthly supplies only — the CGM device or receiver itself is billed separately under HCPCS E2103. Continued coverage requires ongoing CGM use consistent with Medicare guidelines.
