The EIDBI CMDE is the document that turns a diagnosis into a covered service. Under Minn. Stat. § 256B.0949, subd. 5, a comprehensive multidisciplinary evaluation (CMDE) must be completed to determine medical necessity for Early Intensive Developmental and Behavioral Intervention (EIDBI), and the commissioner will not authorize EIDBI services until the CMDE provider has submitted it.
For a family, the CMDE decides whether treatment can start. For an EIDBI agency, it is the foundation of the individual treatment plan (ITP) and the first thing a reviewer asks for. For the clinicians who perform it, the CMDE is a distinct enrollment and billing code with its own authorization rules.
This guide covers content, who can perform it, billing, how it feeds the ITP and authorization, update timing, common deficiencies, and coordination with the diagnosis, as of September 2026. For the benefit as a whole, start with the What is EIDBI guide.
What the CMDE must contain under subd. 5
Subd. 5(c) lists the required content. The Department of Human Services (DHS) form for the CMDE Medical Necessity Summary Information, DHS-7108, organizes the same elements for submission.
| Required element | Statute text, paraphrased |
|---|---|
| Confirmation of the diagnosis | The CMDE provider must review the diagnostic assessment to confirm the person has an eligible diagnosis and that the assessment meets subd. 4 |
| Direct-observation assessment | An assessment of the person's developmental skills, functional behavior, needs, and capacities based on direct observation, administered by the CMDE provider |
| Medical information | Medical or assessment information from the person's physician, advanced practice registered nurse (APRN), or physician assistant |
| Other input (optional) | Input from family members, school personnel, child care providers, or other caregivers, and assessment information from other licensed professionals such as therapists, licensed school personnel, or mental health professionals |
| Caregiver preferences | The legal representative's or primary caregiver's preferences for involvement in the person's treatment |
| Modality information | Information about the range of current EIDBI treatment modalities recognized by the commissioner |
Subd. 5(a) adds that the information and assessments must be performed, reviewed, and relied upon for the eligibility determination, the treatment recommendations, and the treatment plan. A CMDE with observations but no service recommendation leaves the ITP writer nothing to build on. Subd. 3a also requires the CMDE provider, with the QSP, to adapt the evaluation and its recommendations to the person's and family's culture, values, and language.
Since July 1, 2025 the modalities the commissioner recognizes are applied behavior analysis (ABA), DIR/Floortime, the Early Start Denver Model (ESDM), and Relationship Development Intervention (RDI). A CMDE that still describes PLAY Project or Early Social Interaction as available options is out of date.
Who can perform an EIDBI CMDE
Subd. 5a sets three requirements. A CMDE provider must:
- Be a licensed physician, an APRN, a physician assistant, a mental health professional, or a clinical trainee qualified under § 245I.04, subd. 6.
- Have at least 2,000 hours of clinical experience in the evaluation and treatment of people with ASD or a related condition, or equivalent documented graduate coursework from an accredited university in ASD diagnosis, ASD treatment strategies, and child development.
- Be able to diagnose, evaluate, or provide treatment within their scope of practice and professional license.
The CMDE provider enrolls with Minnesota Health Care Programs (MHCP) directly and carries a CMDE qualification on the provider record. The provider does not need to be affiliated with an EIDBI agency, and a CMDE claim does not need a qualified supervising professional (QSP) listed on it, because the CMDE is a covered service under subd. 13(e) in its own right. Many CMDE providers also serve as QSPs at an agency, but the two roles are enrolled and attested separately; the EIDBI provider requirements guide covers both.
When the CMDE is performed inside the agency that will treat the person, keep the CMDE provider's credentials and 2,000-hour evidence in the same file as the evaluation, since a reviewer checks them together.
How the CMDE is billed
The CMDE is billed under CPT 97151, behavior identification assessment, in 15-minute units with the UB modifier that every EIDBI code carries. The midpoint rule applies: a unit is billable only when at least 8 minutes of it were delivered during continuous service. The EIDBI billing codes guide covers units, modifiers, and the claim loops.
For fee-for-service Medical Assistance the review agent is Acentra Health; for a person enrolled in a managed care plan, the submission goes to the plan. The CMDE-specific rules are in the table.
| Item | Rule | Source |
|---|---|---|
| Code and modifier | 97151 with UB | DHS EIDBI billing grid |
| Unit | 15 minutes, midpoint rule | DHS billing grid; MHCP provider news December 2025 |
| Authorization | One CMDE per calendar year without a service agreement | DHS EIDBI manual |
| Submission | DHS-7108 through the Acentra Atrezzo portal, as a separate case from the ITP | Acentra CMDE checklist |
| Review timeline | 7 calendar days; 10 calendar days to respond to a pend | MHCP provider news December 2025 |
| Retroactive requests | Up to 6 months; older requests are rejected | Acentra CMDE checklist |
How the CMDE feeds the ITP and authorization
Subd. 6(b) requires the ITP to be based on the diagnosis and the CMDE information, and subd. 6(a) says the QSP, Level I, or Level II provider who develops the ITP must integrate and coordinate the person and family information from the CMDE. The DHS manual states that the ITP and CMDE may be signed on the same day, but the ITP must not be signed before the CMDE is completed. That sequence is the first thing a reviewer checks.
The chain runs like this. The CMDE establishes medical necessity and recommends services. The ITP specifies each service's frequency, intensity, location, and duration, its baseline measures, and the level of caregiver training. The authorization request, which the manual limits to a 180-day span, asks for the units the ITP supports. Progress monitoring under subd. 7 is submitted after each six months of treatment to reauthorize. The EIDBI documentation guide lists the ITP and progress monitoring elements.
Compliance note: an ITP that requests a service, a setting, or an intensity the CMDE never discussed is the most common mismatch in pended requests. If the CMDE recommends center-based individual intervention and the ITP asks for home-based higher provider ratio intervention, the reviewer will ask why. Either the CMDE needs an addendum or the ITP needs a documented rationale.
When the CMDE is updated
The statute sets no fixed interval. Subd. 5 describes the CMDE as the evaluation that determines medical necessity and subd. 7 places ongoing review in the six-month progress monitoring, which the CMDE provider or QSP may call for more often. Payer guidance fills the gap, and it is not uniform.
| Source | What it says about timing |
|---|---|
| Minn. Stat. § 256B.0949, subd. 5 | No interval stated |
| DHS EIDBI manual | An annual CMDE must be completed and submitted at least 30 days, and no more than 60 calendar days, before the end date of the current service authorization period; one CMDE per calendar year without a service agreement |
| Medical review agent CMDE checklist (January 2022) | The CMDE is not required every year but is required at least once every three years or as clinically necessary |
| Managed care organizations | Each plan sets its own reauthorization documentation; Blue Cross, for example, asks for the ITP with initial, six-month, and annual requests |
Because the manual refers to an annual CMDE while the older checklist refers to three years, confirm the current expectation with the EIDBI Benefit Policy Manual and the person's payer, and document the clinical reason for any re-evaluation outside that schedule. A CMDE update is also warranted when progress monitoring identifies a significant change in the person's condition or family circumstances, or when the modality changes.
Common CMDE deficiencies that cause denials
The medical review agent's CMDE checklist, and the statute behind it, point to the same short list of failures:
- Signature page missing or unsigned. The final signature by the legal guardian or provider indicates the CMDE is complete, and signatures must be handwritten or use an approved electronic signature with a date and time stamp.
- Signer without legal authority. Only a person who can consent to treatment and make legal decisions may sign; not every caregiver qualifies.
- Outdated diagnostic codes. The diagnostic section must use current ICD codes or DC:0-5 codes for young children.
- Stale observation. The direct observation by the CMDE provider must fall within 60 days of the completion date.
- No well-child checkup within the past year, unless a screening exception is indicated.
- Wrong payer. A request for a person enrolled in a prepaid health plan sent to the fee-for-service agent is rejected.
- Late retroactive request. Services delivered more than six months before submission are rejected outright.
- Statutory content gaps. No medical information from a physician, APRN, or physician assistant; no record of caregiver preferences; no modality information; or a related-condition case that does not document the three core deficits required by subd. 2.
- Diagnostic assessment that does not meet § 245I.10, subd. 6, or that the CMDE provider never reviewed.
Coordinating the CMDE with the medical diagnosis
The CMDE does not replace the diagnosis, and the diagnosis does not replace the CMDE. Subd. 4 requires the diagnosis of ASD or a related condition to be based on current DSM criteria, including direct observation and information from the legal representative or primary caregivers; to be completed by a physician, APRN, physician assistant, or mental health professional; and to meet the standard diagnostic assessment requirements of § 245I.10, subd. 6. Additional information from special education evaluations, licensed school personnel, and speech, psychology, occupational, or physical therapy professionals may be considered.
Subd. 5(b) then requires the CMDE provider to review that diagnostic assessment and confirm both the eligible diagnosis and the assessment's compliance with subd. 4. If the CMDE provider elects to complete the diagnostic assessment at the same time as the CMDE, they must certify that it meets subd. 4. The practical result is one file with three dated items: the diagnostic assessment, the medical information from the primary care provider, and the CMDE itself, each with the signer's credentials. When the diagnosis came from outside the agency, obtain the full assessment rather than a summary letter, because the CMDE provider has to review the assessment, not the conclusion.
How Trustora helps
Trustora stores the EIDBI CMDE as a structured record with the § 256B.0949, subd. 5 elements as required fields: the reviewed diagnostic assessment, the dated direct observation, the medical information source, caregiver preferences, and the modality information. The CMDE provider's credentials and 2,000-hour evidence attach to the record, and the ITP cannot be finalized with a signature date earlier than the CMDE completion date.
The claims workflow bills 97151 with the UB modifier from the recorded time, tracks the one-per-calendar-year rule and the seven-day and 10-day Acentra windows, and posts the authorization outcome back to the person's record. When a reviewer asks for the chain, the one-click DHS audit binder produces the diagnosis, CMDE, ITP, and authorization together. See the platform overview for the EIDBI module.
