National Correct Coding Initiative (NCCI) Edits
A. The Division of Medicaid defines National Correct Coding Initiative (NCCI) edits as edits
implemented in the Medicaid Management Information System (MMIS) to control improper
coding leading to inappropriate payments which includes:
1.
NCCI procedure to procedure (PTP) edits defined as pairs of Healthcare Common
Procedure Coding System (HCPCS)/Current Procedural Terminology (CPT) codes
that cannot be billed together, and
2.
NCCI medically unlikely edits (MUEs) defined for each HCPCS/CPT code utilizing
the maximum units of service that a provider would report under most circumstances
for a single beneficiary on a single date of service.
B. The Division of Medicaid requires providers to follow the Medicaid National Correct Coding
Initiative (NCCI) policies and edits:
1.
Medicaid NCCI and medically unlikely edit (MUE) values are reviewed with the
quarterly file updates, and
2.

C. Providers must append NCCI associated modifiers only when appropriate clinical
circumstances are documented in accordance with the NCCI policies and the HCPCS/CPT
Manual instructions/definitions for the modifier/procedure code combination. A modifier
cannot be appended to a HCPCS/CPT code solely to bypass an NCCI PTP edit if the clinical
circumstances do not justify its use.
D. Providers are required to bill for services according to Medicaid NCCI coding policies, the
Fee Schedules on the Division of Medicaid’s website and/or Administrative Code.
