Modifier SA, AS & 80 - physician assistant and advanced nurse practioner modifier

Supervision of Physician Assistant, Advanced Nurse Practitioner or Certified Registered Nurse First Assistant

The following modifiers should be used by the supervising physician when he/she is billing for services rendered by a Physician Assistant, (PA), Advanced Nurse Practitioner (APN) or Certified Registered Nurse First Assistant (CRNFA):

AS Modifier: A physician should use this modifier when billing on behalf of a PA, ANP or CRNFA for services provided when the aforementioned providers are acting as an assistant during surgery. (Modifier AS to be used ONLY if they assist at surgery)

Modifier AS Physician Assistant (PA), Nurse Practitioner (NP) or Clinical Nurse Specialist (CNS) assistant at surgery services.

Instructions

Append this modifier to appropriate procedure codes when Non-Physician Practitioners (NPPs) are assisting a principal surgeon as an assistant surgeon. The assistant at surgery provides more than ancillary services. NPPs include a CNS, NP and PA.

Correct Use

    The Medicare Physician Fee Schedule (MPFS) Indicator/Descriptor lists under column A will confirm if assistant at surgery is allowed.
        2 = payment restriction for assistants at surgery does not apply to this procedure. Assistant surgeon may be paid).
    NPP, mid-level practitioner or advance practice practitioner (APP)
        Append this modifier only
    NPP must accept assignment
    NPPs are allowed 85% of 16% physician fee allowable or 14% of surgery

Incorrect Use

    Inappropriate for NPPs to use modifiers 80, 81 or 82 (physician only modifiers)
    Modifier 80 (assistant surgeon), 81 (minimum assistant surgeon) or 82 (qualified resident surgeon not available) with physician (MD/DO) assisting at surgery


SA Modifier: A supervising physician should use this modifier when billing on behalf of a PA, ANP, of CRNFA for non-surgical services. (Modifier SA is used when the PA, ANP, or CRNFA is assisting with any other procedure that DOES NOT include surgery.)


Assistant Surgeon Modifiers

Modifier 80, 81, 82: Denote assistant surgeons. Should be submitted on those surgical procedures where an assistant surgeon is warranted. NOTE: Physicians acting as assistants cannot bill as co-surgeons. Benefits will be derived based on CMS designation for Assistant Surgeon.

-80 Modifier: PA’s, ANP’s, and CRNFA’s who are billing with their own provider number will not need to bill a modifier, unless they are billing as an Assistant Surgeon, then they must use the –80 modifier.


Billing and Coding Guidelines

A non-physician assistant-at-surgery is required to actively assist the surgeon and participate in the actual performance of the procedure. The operative report documents  the specific service(s) the non-physician assistant surgeon rendered.

Modifier AS should not be used if the Physician Assistant, Nurse Practitioner or Clinical Nurse Specialist is acting as an “extra” pair of hands and not a surgical assistant in place of another surgeon.

Codes that are eligible for multiple surgical reductions will be adjusted when multiple surgical procedures are performed at the same surgical session.


Coding Assistant at Surgery Services Rendered in a Method II CAH

An assistant at surgery is a physician or non-physician practitioner who actively assists the physician in charge of the case in performing a surgical procedure.
Medicare makes payment for an assistant at surgery when the procedure is authorized for an assistant and the person performing the service is a physician, physician assistant (PA), nurse practitioner (NP) or a clinical nurse specialist (CNS).

Assistant at surgery services rendered by a physician or non-physician practitioner that has reassigned their billing rights to a Method II CAH are payable by Medicare when the procedure is billed on type of bill 85X with revenue code (RC) 96X, 97X or 98X and an appropriate assistant at surgery modifier.

Under authority of 42 CFR 414.40, CMS establishes uniform national definitions of services, codes to represent services, and payment modifiers to the codes. This includes the use of payment modifiers for assistant at surgery services.

Modifier 80 (assistant surgeon), 81 (minimum assistant surgeon), or 82 (when qualified resident surgeon not available) is used to bill for assistant at surgery services. When billed without modifier AS (PA, NP or CNS services for assistant at surgery) the use of these modifiers indicate that a physician served as an assistant at surgery.

Modifier AS is billed to indicate that a PA, NP or CNS served as the assistant at surgery.

Modifier 80, 81 or 82 must also be billed when modifier AS is billed. Claims submitted with modifier AS and without modifier 80, 81 or 82 are returned to the provider

PHYSICIAN ASSISTANTS

Louisiana Medicaid enrolls and issues individual Medicaid provider numbers to Physician Assistants (PA). Medicaid requires that all services provided by the PA be billed identifying the physician assistant as the attending provider.

Unless otherwise excluded by Louisiana Medicaid, the services covered are determined by individual licensure, scope of practice, and supervising physician delegation. The supervising physician must be a Medicaid enrolled physician. Clinical practice guidelines and protocols shall be available for review upon request by authorized representatives of Louisiana Medicaid.


Services  provided by a physician assistant shall not be billed when he/she is employed by or under contract with providers whose reimbursement is based on costs that include these salaries.

The reimbursement for services rendered by a physician assistant shall be 80% of the professional services fee schedule and 100% for KIDMED medical, vision, and hearing screens and immunizations.

Billing Information

Please note the following billing instructions and enrollment requirements regarding PA services

• PA services are billed on the CMS 1500/837P form.

• Services provided by the PA must be identified by entering the provider number of the PA in block 24J, and the group number must be entered in block 33B.

• Physicians who employ or contract with PAs must obtain a group provider number and link the PAs individual provider number to the group number. Physician groups must notify Provider Enrollment of such employment or contracts when PAs are added or
removed from the group.

• Qualified PAs who perform as first assistant in surgery should use the “-AS” modifier to identify these services.

Services rendered by the physician assistant that are billed and paid by Medicaid using a physician’s number as the attending provider are subject to post payment review and recovery.

First Assistant in Surgery

Louisiana Medicaid will reimburse for only one first assistant in surgery. Ideally, the first assistant to the surgeon should be a qualified physician. However, in those situations when a physician does not serve as the first assistant; qualified, enrolled, advanced practice registered nurses and physician assistants may function in the role of a surgical first assistant and submit claims for their services under their Medicaid provider number. The reimbursement of claims for more than one first assistant is subject to recoupment.
