Covered Services and Limits

General Provider Policies

The General Provider Policies details basic coverage requirements for all services. Basic coverage requirements include:

• The provider must be enrolled in ND Medicaid;
• Services must be medically necessary;
• The member must be eligible on the date of service; and
• If applicable, the service has an approved service authorization. 

The Procedure Code Look-up Tool  can be used to identify if a procedure code is covered by ND Medicaid along with code specific details such as ORP requirements, Service Authorization requirements, and current rates. 

Speech-language pathology services must be of a level of complexity and sophistication, or the condition of the member must be of a nature that requires the judgment, knowledge, and skills of a qualified speech-language pathologist. 

Speech-language pathology includes those services necessary for the evaluation and treatment of speech, hearing, and language disorders that result in communication disabilities and for the evaluation and treatment of swallowing disorders (dysphagia) regardless of the presence of a communication disability.

Speech-language services provided on an ongoing basis to maximize the member’s functional level is covered for members who have.

Speech-language services provided on an ongoing basis to maximize the member’s functional level is covered for members who have:

• experienced trauma;
• a chronic condition; or
• a condition due to congenital abnormality, deprivation, or disease that interrupts or delays the sequence and rate of normal growth, development, and maturation. 

ND Medicaid covers the following CPT® codes; codes not specifically listed are not covered by ND Medicaid:

Asterisk (*) counts against unit limits related to non-evaluation services. 

Pound (#) counts against limits related to evaluation services.

With the exception of group therapy, ND Medicaid requires direct (one-on-one) contact with the patient by the provider (constant attendance). Coverage for these codes indicates the provider is performing the modality and cannot be performing another procedure at the same time. Only the actual time of the provider’s direct contact with the patient, providing services requiring the skills of a therapist, is covered.

CPT® 92507, Modifier

Although untimed codes do not include time units in their descriptors, underlying times associated with each CPT® code have been used to determine the value of the evaluation or treatment. CPT® 92507 – treatment of speech, language, voice, communication and/or auditory processing disorder; individual – has a total underlying time of 60 minutes. 

Effective for all members for the dates of service on or after Feb. 1, 2026:

• When less than 35 minutes of face-to-face time is spent performing CPT® 92507, modifier -52 (reduced service) must be appended to the claim line and will be reimbursed at 50% of the current fee schedule amount.
• When greater than 90 minutes of face-to-face time is spent performing CPT® 92507, modifier -22 (increased service) must be appended to the claim line and will be reimbursed at 120% of the current fee schedule amount.

Time spent with the member must be noted in the documentation.

Speech Therapy Assistants

Effective for dates of service July 1, 2025, and forward, ND Medicaid will require services rendered by a certified speech language pathology therapy assistant (SLPA) to be identified on the claim line using the UB modifier. The SLPA must be listed as the rendering/servicing provider in the medical records. The medical records must contain the signature of both the supervising provider and the rendering provider. 

The supervising provider NPI and taxonomy must be listed as the rendering (CMS 1500 claim form or 837p) or attending (UB 04 claim form or 837i) provider on the claim. 

Orders for Care

Speech-language pathology services require an order (prescription) for evaluation and treatment from a physician or other licensed practitioner (OLP) allowed to prescribe under their scope of practice according to state law. An order is valid for one (1) year. If continued services are needed beyond one year, a new order must be written. 

Plan of Care 

Speech-language pathology services must be provided in accordance with a documented plan of care that is dated and signed by the speech-language pathologist responsible for oversight of the plan.

The initial plan of care shall contain, at minimum:

• Diagnoses;
• A description of the member’s functional status;
• The objectives of the speech-language service;
• Short-term treatment goals;
• Long-term treatment goals; and
• Type, amount, duration, and frequency of therapy services.

The plan of care must be consistent with the related evaluation which is considered part of the plan. The plan should provide for treatment in the most efficient and effective manner and anticipate progress toward achieving the treatment goals within a medically reasonable amount of time, generally not to exceed 90 days. Long-term treatment goals should be developed for the entire episode of care in the current setting. When the episode is anticipated to be long enough to require more than one certification, the long-term goals may be specific to the part of the episode that is being certified. 

Goals must be:

• Measurable; and 
• Pertain to identified functional impairments. 

Therapists must establish and update short and long-term goals, based on member progress, to track the episode of care. The recipient’s care plan must clearly document the need for these services, including attempts to resolve treatment.   

The speech-language therapist must update the plan of care within 90 days of the initial evaluation or first therapeutic encounter; and each 90-day interval throughout the course of treatment. With each 90-day interval, the plan of care must be certified 

(signed and dated) by the ordering or referring provider who has knowledge of the need for and supports ongoing therapy services for the member.

Updates to the plan of care must include:

• Prior short-term goals;
• Prior long-term goals;
• Explanation of progress toward goal attainment since initial or previous plan of care update;
• Explanation of lack of progress toward goal attainment since initial or previous plan of care update; and
• New, modified, or carried-over long-term and short-term goals based on progress or lack of progress.

Group Therapy

Group therapy (2-6 members) supplements but does not replace individual therapy. Group therapy may not represent the entire care plan for any individual. Need for group therapy must align with American Speech-Language-Hearing Association guidelines and be documented in the Plan of Care and include the following: 

• Justification for group (vs. individual) treatment for each treatment session; 
• Specific goals targeted and how the group activity supports these goals;
• How the group activities use medically necessary skilled interventions and are supported by the member’s established plan of care; 
• Member’s response to the group activities and related data; 
• Percentage of treatment that group therapy represents; and 
• Need for the continuation of group therapy.

Limits

Speech therapy evaluations are limited to one per calendar year. The speech therapy evaluation limit is a combined limit of CPT® codes 92521, 92522, and 92523. Speech therapy units are limited to:

• 30 units per calendar year for members age 21 and over.

For example, if a visit is 30 minutes, this equates to two (2) 15-minute timed units or one untimed or 30-minute unit. The initial units (30 for members age 21) are available for speech therapy provided in any setting. Providers delivering therapy services to the member must coordinate with other facilities (i.e. schools and private agencies) to ensure all services align to provide the member with continuity of care and progress towards goals on the member’s care plan without duplication. 

It is the responsibility of the provider to confirm the availability of units through MMIS or by calling the Call Center at 701-328-7098 or 877-328-7098. If additional units are medically necessary for a member over the limits, the provider must submit a service authorization (SA). Any additional units approved through a service authorization can only be utilized by the facility or provider who submitted the SA. Service authorizations may be approved for multiple agencies for a member if it is medically necessary.

Please see the Service Authorization section below for more information.

Note: A therapy units count obtained through ND Medicaid will only include adjudicated claims. Providers must also verify more recent therapy services with the member or member’s guardian.

Maintenance Therapy

ND Medicaid does not cover maintenance therapy. If therapy services are needed to sustain a level of function or if the member’s condition would otherwise deteriorate, services may be covered by ND Medicaid. The member’s plan of care must clearly document the need for services, including attempts to resolve and reduce treatment. 

The plan of care must include member therapy activities to facilitate progress and prevent deterioration of skills outside of the therapy appointment. Speech therapy services needed to sustain a level of function or if the member’s condition would otherwise deteriorate must be supported by the medical diagnosis and appropriate developmental milestones. 

Documentation must contain the following:

• A specific International Classification of Diseases (ICD-10) code based medical diagnosis; and
• Specific interventions related to the diagnosis that
  • Are focused on the documented limitations and issues that cause recurring developmental delays; and/or
  • Address issues in other areas of development or difficulty with certain skills that are being addressed through continued care.

Treatment for conditions which are not supported by a specific ICD-10 or current diagnosis where recipients can reasonably be expected to spontaneously improve with age and development do not meet the need for therapy.

Duplicate Therapy

ND Medicaid does not cover duplication of services. Members may receive speech language pathology services from more than one provider when:

• The care is delivered collaboratively, pursuant to an already existing Plan of Care; or 
• The services are delivered by a school district as specified in the member’s Individualized Education Plan (IEP). Therapy services received outside of an IEP cannot duplicate therapy services received through the member’s IEP. 

When multiple providers are delivering therapy services, the providers must collaborate to ensure that services are not duplicative and are delivered according to the plan of care. Providers must be prepared to show proof of collaboration without duplication of services.

Services Delivered to an Inpatient or Resident in a Facility

Speech language pathology services provided to a resident at a nursing facility, swing bed, hospital, or Intermediate Care Facilities for Individuals with Intellectual Disabilities (ICF/IID) are not separately billable. ND Medicaid pays for speech language pathology services through the rate established for these facilities.

Individualized Education Plan (IEP) Services

Speech Language Pathology services provided as directed by an IEP must be: 

• Authorized or prescribed and outlined in the student’s IEP;
• Updated on the student’s IEP as services start or stop; 
• Billed by a public school or special education unit; and
• Documented in accordance with Outpatient Rehabilitation Therapy Documentation Requirements.

The services are delivered by a school district as specified in the member’s Individualized Education Plan (IEP). Therapy services received outside of an IEP cannot duplicate therapy services received through the member’s IEP. When multiple providers are delivering therapy services, the providers must collaborate to ensure that services are not duplicative and are delivered according to the plan of care. Coordination is especially critical for children who are receiving services in multiple environments. Providers must be prepared to show proof of collaboration without duplication of services. Written parent consent is required prior to any exchange of information with medical providers.

Other service requirements include:

• Other health-related services must be authorized by an other licensed practitioner (OLP) operating within their scope of practice;
• ND Medicaid will not directly pay private schools for IEP-related services.

Service Authorization Requirements

ND Medicaid requires a service authorization for:

• Additional evaluations; 
• Reevaluations; and
• Therapy units that exceed the following limits:
  • For members age 21 and over:
    • 30 units per year.

The speech therapist must obtain an approved service authorization from ND Medicaid for the member prior to performing the requested services. To check a member’s available therapy units, contact the Call Center at 701-328-7098 or 877-328-7098. 

Note: A therapy units count obtained through ND Medicaid will only include adjudicated claims. Providers should also verify more recent therapy services with the member or member’s guardian. 

Service Authorization requirements include:

• A completed and current version of Service Limits Service Authorization Request (SFN 481) with the corresponding order for services;
• A copy of the current physician signed plan of care; 
• Short term and long-term goals and progress or lack of progress towards those goals and;
• All relevant progress notes.
  • If a member is getting therapy from multiple providers, including ABA services for Autism Spectrum Disorder, appropriate documentation is required showing collaboration without duplication of services.

Upon receipt of the completed service authorization request, including the current plan of care and progress notes, ND Medicaid will evaluate the request for additional services based on the following:

• Medically necessary:
  • In addition to meeting the Medically Necessary requirements defined in North Dakota Administrative code 75-02-02-03.2(10), the services must meet the following requirements:
    • Require the judgement, knowledge and expertise of a qualified speech therapist due to the complexity of the situation; 
    • The services are accepted standards of medical practice specific and effective for the treatment of the member’s condition; and 
    • The services are provided with the expectation the member will improve in a reasonable and generally predictable period of time based on the ordering provider’s assessment.
• Member compliance with home-based care plan elements between visits; 
• Progress towards goal attainment since initial or previous plan of care update;
• Lack of progress toward goal attainment since initial or previous plan of care update;
• New, modified or carried-over goals based on progress or lack of progress towards initial goals; and
• Type, amount, duration, and frequency of continued therapy services:
  • The care plan should be based on the minimum amount of units required to meet the member’s care plan goals.

Approved service authorizations will be for units with the provider who submitted the service authorization. For example, if the school district submits the service authorization and is approved for more units, those services must be provided at the school and cannot be utilized by an alternative facility or provider. Service authorizations may be approved for multiple agencies for a member if it is medically necessary.

Service authorizations for new evaluations or revaluations may not be approved when a member has missed appointments or fails to follow through with the recommended plan of care.

Retroactive Authorization

To be eligible for retroactive authorization consideration, all requirements for service authorization must be met, and ND Medicaid must receive the retroactive authorization request no later than 90 days from the date the service. The speech-language pathologist must demonstrate good cause for the failure to secure the required prior service authorization request. Retroactive authorization requests are reviewed on a case-by-case basis. Frequent requests for retroactive authorization may be considered abuse of the program.

Providers must keep legible medical and financial records that fully justify and disclose the extent of services provided and billed to ND Medicaid. Records must be retained for at least 7 years after the last date the claim was paid or denied. Providers must follow the documentation requirements in the Provider Requirements Policy. 

Documentation must be unique, and specific to the date of service provided, be representative of what the therapist has provided, and must support the procedures that are billed to ND Medicaid. For Plan of Care requirements see the “Plan of Care” section above. Additionally, the following must be documented:

• Time spent rendering a service for all time-based codes. Start and stop time is required for all time-based codes. 
• Description of treatment/service provided. These records are used to decide medical necessity and correct billing. 
• Dates of services provided.
• Dated signature, authenticated electronic or handwritten, of provider for each session. The use of signature stamps is not allowed. Signature must be dated.

Reimbursement Methodology and Claim Instructions

Timely Filing

ND Medicaid must receive an original Medicaid primary claim within one hundred eighty (180) days from the date of service. The time limit may be waived or extended by ND Medicaid in certain circumstances. The Timely Filing Policy contains additional information.

Third-Party Liability

Medicaid members may have one or more additional source of coverage for health services. ND Medicaid is generally the payer of last resort. Providers must pursue the availability of third-party payment sources. The Third Party Liability Policy contains additional information.

Client Share (Recipient Liability)

Client share (recipient liability) is the monthly amount a member must pay toward the cost of medical services before the Medicaid program will pay for services received. The Client Share Policy contains additional information. 

Reimbursement

A claim for services must be submitted at the provider’s usual and customary charge. Payment for services is limited to the lesser of the provider’s usual and customary charge or the ND Medicaid calculated reimbursement. 

Speech Language Pathology services are reimbursed according to the ND Medicaid fee schedule. Fees are calculated based on the relative value unit (RVU) and the ND Medicaid conversion factor.

A unit of time is attained when the mid-point is passed. For example, a 15-minute unit is attained when 8 minutes have elapsed. A second 15-minute unit is attained when a total of 23 minutes has elapsed.

When billing for one code that is billed in units (i.e. 15 minutes) throughout a day, report the total amount of units on one claim line.

Clinic Based Services

Speech-language pathology services must be billed using the CMS 1500 claim form or 837p. 

Outpatient Hospital Based Services

Speech-language pathology services must be billed using the UB 04 claim form or 837i.

Frequently Asked Questions

Question (Q): Can therapy students bill for services?
Answer (A): Services provided by students enrolled in a medical training program may be billed under the supervising provider if:

• The provider provides direct supervision of the student for the duration of the time services are being provided to the member. Direct supervision means that the supervising provider may immediately intervene in service delivery as necessary. 
• There are no more than six (6) students providing services to every one (1) direct supervising provider.
• There is a contract with the education institution, or the education institution has a policy in place outlining the requirements for supervision of students providing services to Medicaid members. The policy or contract must be provided to ND Medicaid upon request.

The supervising provider is responsible for: 

• satisfying all applicable state law and regulatory supervision requirements; and
• patient care provided by a student.

Q: Why is ND Medicaid requiring claims be billed with the therapy assistant modifier UB?
A: ND Medicaid is requiring the use of modifier UB, for services provided by the therapy assistant to add transparency and understanding of who is providing services to our members.

Q: Are providers required to request additional services from the primary payor once they have exhausted the primary insurance benefit limits?
A: Yes, providers are expected to request additional visits from the primary insurance and follow any requirements set forth by the primary insurance.

Q:If the primary insurance does not recognize and pay assistants, can we bill ND Medicaid as primary?
A: No, primary requirements must be followed, and the patient should not be scheduled with that provider type.

Q: Does ND Medicaid automatically pay as primary when Third Party Liability (TPL) benefits have been exhausted, and the primary doesn’t extend benefits?
A: No, ND Medicaid does not automatically become the primary pay. The provider must take the appropriate steps to obtain additional benefits from the primary payor and share the reason and proof for denial of with ND Medicaid upon claim submission.
