HCPCS II Device Codes
These codes are used by the entity that purchased and supplied the medical device, DME, drug, or supply to the patient. For insulin pumps and Personal CGM, this is typically a DME Supplier.
| Product | Code | Description |

| Alcohol wipes | A4245 | Alcohol wipes, per box |
| Betadine swabs, per box | A4247 | Betadine or iodine swabs/wipes, per box |

CPT/HCPCS II Codes for Provider Services
Providers use CPT (and certain HCPCS II) codes for all services. Under Medicare’s Resource-Based Relative Value Scale (RBRVS) methodology for physician payment, each code is assigned a point value, the relative value unit (RVU), which is then converted to a dollar payment amount. Many private payors use Medicare RVUs as the basis of their payment rates.
| Service | Code and Description | Providers Who Can Perform the Service | Payment Level* |
|---|---|---|---|
| Initial CGM training, hookup, and download | 95250** Ambulatory continuous glucose monitoring of interstitial tissue fluid via a subcutaneous sensor for a minimum of 72 hours; sensor placement, hook-up, calibration of monitor, patient training, removal of sensor, and printout of recording | Qualified health care providers, consistent with state scope of practice laws | Medicare RVUs: 3.56 Medicare does not cover Personal CGM, but does publish RVUs for these codes. |
| Interpretation of CGM data | 95251 Ambulatory continuous glucose monitoring of interstitial tissue fluid via a subcutaneous sensor for a minimum of 72 hours; interpretation and report | MD/DO NP/PA | Medicare RVUs: 1.10 Medicare does not cover Personal CGM, but does publish RVUs for these codes |
| Pre-/post-CGM evaluation | Evaluation and Management(E/M) Codes:*** 99354-99355 Prolonged service, office (must be billed with 99212-99215) | MD/DO NP/PA | 99212-99215 Medicare: $37-$125 Medicare RVU: 1.03-3.46 99354-99355 Medicare: $92-$91 Medicare RVU: 2.55-2.52 |
* Medicare 2009 national average allowable amount, rounded to the nearest full dollar amount. Includes 20% patient copayment amount. All RVUs are for services performed in the physician’s office.

** Use the reduced service modifier (-52) if the patient owns the equipment (therefore not an expense to the provider).
*** An office visit can only be billed separately when a CGM service is provided to the same patient on the same day if a full-scale, separately identifiable evaluation and management service takes place in addition to the CGM service. In this circumstance, the modifier -25 should be billed with the E/M code to indicate that a separate and distinct E/M service was provided.
