HCPCS Level II Codes

HCPCS II codes are a supplement to CPT® codes.6 Although some HCPCS II codes are for procedures and services not classified in CPT, the majority of HCPCS II codes are for supplies, durable medical equipment (DME), drugs, and medical devices. In many situations, CPT and HCPCS II codes must be used together to completely describe a service. In particular, CPT codes indicate the procedure performed and HCPCS II codes identify the specific device, supply, DME, or drug utilized in the procedure. The HCPCS 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 continuous glucose monitoring (CGM), this is typically a DME supplier.

Some items have more than one code. For example, a device may have an E-code as well as an S-code. This reflects payer preference, as only private payers use S-codes although private payers may also use E-codes. A supply may have more than one A-code, which also reflects payer preference in that one A-code is not payable by certain payers but another A-code is.

DIABETES EDUCATION CODES

Diabetes education may consist of patient management to begin insulin pump therapy (also called continuous subcutaneous insulin infusion or CSII) as it relates to insulin, such as carb ratios, basal rates, sick day management, or insulin sensitivity for correction factor. Medical nutrition therapy specifically focuses on dietary intervention to ensure eating habits are appropriate for persons with diabetes. For Medicare, diabetes self-management training and medical nutrition therapy are completely separate benefits.

Providers use CPT® codes for all services, along with select HCPCS II codes. 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 payers use Medicare RVUs as the basis of their payment rates. The RVUs shown are for services performed in the non-facility setting, e.g., in the office.

CGM SERVICES CODES

Codes related to continuous glucose monitoring (CGM) differentiate between the technical service of sensor placement and patient training, performed by office staff, and the professional service of interpreting the CGM data, performed by clinicians. For the technical service, different codes are assigned depending on whether the patient or the physician practice owns the CGM equipment.

Providers use CPT codes for all services, along with select HCPCS II codes. 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 payers use Medicare RVUs as the basis of their payment rates. The RVUs shown are for services performed in the non-facility setting, e.g., in the office.

The codes shown are examples of specific types of complications within that subcategory. Other codes are available for different complications within the same subcategory. The table is for illustrative purposes only and is not an exhaustive or all-inclusive list of ICD-10-CM diabetes diagnosis codes.

Diabetes characterized as uncontrolled, out-of-control, inadequately controlled, or poorly controlled diabetes is coded to hyperglycemia in ICD-10-CM, unless the lack of control refers to low blood sugar (hypoglycemia).

3

A seventh digit must be appended to the code to identify which eye is affected.

4

Medication status is only coded in a secondary position, following the code for diabetes mellitus.

5

Code Z79.4 can also be assigned to a patient with type 2 diabetes mellitus who routinely uses insulin for control. If a patient is treated with both oral hypoglycemic agents and insulin, only Z79.4 is assigned.
