Provider documentation must support the choice of code used and accurately reflect the time spent prescribing, if applicable.

Diagnostic Testing

Claims must be billed on a Centers for Medicare & Medicaid Services (CMS) 1500 professional claim. The affiliated pharmacy or clinic’s National Provider Identification (NPI) should be used as the billing provider and the pharmacist’s NPI as the rendering provider. The pharmacist’s NPI may also be used as the ordering provider if the same provider is ordering and rendering the test.

Affiliated pharmacies and clinics may only bill for tests performed by their affiliated pharmacists. Tests ordered by pharmacists but performed by laboratories or hospital outpatient laboratories must be billed by the performing laboratory.

Pharmacy Interns, per Department rule 10 CCR 2505-10 8.200.2.D.1. are a non-physician provider that may provide covered goods and services only under the Direct Supervision of an enrolled provider who has the authority to supervise those services, according to the Colorado Department of Regulatory Agencies rules.

Comprehensive Medication Management (CMM) 

Medication management, when rendered as part of a collaborative pharmacy practice agreement, as outlined in 3 CCR 719-1 17.00.00, is a covered benefit.

Procedure Code Modifiers

Modifier FP

When billing for family planning services, such as for contraception provision, always include the family planning (FP) modifier next to the appropriate procedure code on claims. Family planning services and supplies are identified and provided only when the intent of the service is to prevent, delay or plan for a pregnancy. Family planning services can include, but are not limited to: examinations, treatment, all FDA-approved contraceptives/methods of birth control and family planning counseling. 

Modifier FP+32

Effective July 1, 2022, members eligible for expanded family panning benefits require modifier FP and 32 on services that are defined as family planning related. For more information on these requirements as well as member eligibility, refer to the Family Planning Benefit Expansion for Special Populations Billing Manual.   

Modifier 33

The Department recognizes Modifier 33 when appended to a preventive service(s), as mandated under the terms of the Patient Protection and Affordable Care Act (PPACA) comprehensive healthcare reform law, and defined in accordance with the U.S. Preventive Services Task Force (USPSTF) A and B rating in effect at the time of service.

Use of Modifier 33 will bypass co-pay requirements and is appropriate with a CPT or HCPCS Code(s) that is a diagnostic/therapeutic service that is being performed as a preventative health service that is not for the treatment of illness or injury. For separately reported services specifically identified as preventive, the modifier should not be used. Providers may append Modifier 33 to an Evaluation & Management (E&M) visit only if the primary purpose of the E&M visit is the delivery of a USPSTF grade A or B service, and not if it is simply a component part of a different billed service. 

Billing Edits

The provider's adherence to the application of policies in this manual is monitored through either post-payment review of claims by the Department or computer audits or edits of claims. When computer audits or edits fail to function properly, the application of policies in this manual remain in effect. Therefore, all claims shall be subject to review by the Department.

Anesthesia Services
Anesthesia services must be reported as minutes. Units may only be reported for anesthesia services when the code description includes a time period.

Anesthesia time begins when the anesthetist begins member preparation for induction in the operating room or an equivalent area and ends when the anesthetist is no longer in constant attendance. No additional benefit or additional units are added for emergency conditions or the member's physical status.

The fiscal agent converts reported anesthesia time into fifteen minute units. Any fractional unit of service is rounded up to the next fifteen-minute increment.

Codes that define units as inclusive numbers
Some services such as allergy testing define units by the number of services as an inclusive number, not as additional services.
