Developmental Screening

What is Developmental Screening?

It is the administration of a brief standardized tool to aid in the identification of children at risk of a developmental disability. [Soreca: 2008] Concerning results from the screen should trigger further evaluation for specific developmental disabilities. Developmental screening of ALL children is recommended at the 9, 18, and 30 month well-child visits (or at 24 months if a 30 month visit is not conducted). [Hagan: 2008]

What is Developmental Surveillance?

It is a flexible, longitudinal, continuous, and cumulative process whereby health care professionals identify children who may have developmental problems. Developmental surveillance is recommended to occur at every pediatric visit. If concerns arise as a result of developmental surveillance, a developmental screening tool should be administered or, if there is sufficient concern, further evaluation undertaken for specific developmental disabilities.
How is Developmental Surveillance Different than Developmental Screening?

Developmental surveillance entails:
  1. Listening to parents' concerns
  2. Obtaining and maintaining a developmental history
  3. Observing the child during visits
  4. Identifying risk and protective factors
  5. Documenting relevant information and findings
Developmental screening entails the use of a validated, parent-completed questionnaire. Screening provides greater sensitivity and specificity than surveillance in identifying children who may have developmental delay.

Why is it Recommended to Repeat Developmental Screening at Multiple Ages?

Repeated developmental screening provides a more accurate assessment of development than a one-time evaluation, and developmental screening at multiple ages allows for monitoring of developmental progress (or regression) over time.

What is the Rationale for Developmental Screening?

Developmental disabilities are common, yet many children with developmental disabilities are not identified in primary care settings and opportunities for early intervention thus lost or significantly delayed. [Palfrey: 1987] Developmental screening programs result in increased detection of developmental delays. [Earls: 2009] Participation in an Early Intervention Program improves child and family outcomes. [Berlin: 1998] [Guralnick: 1998] [Reynolds: 2001]

The use of checklists of developmental skills are ineffective because they lack the consistent scoring to trigger referrals found in validated developmental screening tools. Though developmental surveillance could occur at every visit, a variety of issues may lead to its omission or incomplete performance at times. A recent study found that only 57% of parents reported their child’s development was assessed during a pediatric visit. [Zuckerman: 2004] Developmental screening tools can save time in thoroughly evaluating all domains of development (social/emotional, language, cognitive, gross/fine motor). And parents who report receiving developmental screening tools are more satisfied with their pediatric care. [Zuckerman: 2004]

Finally, federal law mandates that health care professionals provide services that identify children with developmental disabilities (Title V of the Social Security Act and the Individuals with Disabilities Education Improvement Act- IDEIA).

Other Names

Some approaches to developmental screening can also encompass social-emotional screening.

Early Signs

See Learn the Signs. Act Early (CDC), a page on the CDC web site providing an overview of developmental milestones and screening.

315, Specific delays in development

317, Mild mental retardation

318, Other specified mental retardation

783.4, Lack of expected normal physiologic development in childhood

The above are general codes, each of which includes a number of more specific codes (with 4th and 5th digits) that should be specified. The last, 783.4, is generally used more for anatomic/physiologic delays or failure to thrive.


96110, Developmental testing, limited

This code reflects the associated physician work and screening program expenses. Compensation varies by geography and insurer. Many insurers “bundle” compensation into their standard compensation for health supervision visits. However, in some states and, particularly, in some Medicaid programs, compensation is provided when the codes described below are submitted. Working with insurers, perhaps through your Chapter of the American Academy of Pediatrics or American Academy of Family Physicians, may be effective in their providing appropriate compensation. For insurers that compensate for screening, the health supervision code is used with the modifier 25 appended and 96110 listed for each screening tool administered.


Bright Futures, 3rd Edition, published in 2008, provides general and specific guidance for health supervision of children, including developmental surveillance and screening. [Hagan: 2008]


For a detailed overview of developmental screening instruments and how to choose one for your practice, see Developmental Screening: Selecting Screening Instruments (Commonwealth Fund). Below is a summary of screening tools that meet the following criteria:
  1. validated for a primary care population
  2. broadband instruments that screen in multiple domains of development
  3. favorable psychometric properties, defined as sensitivity and specificity between 70% and 80%
  4. parent completed questionnaire
  5. administration time of 15 minutes or less
  6. designed for use at the 9, 18 and 30 (or 24) month visits
  7. compatible with electronic medical records
  8. available in multiple languages

Response to a Positive Screen

Primary Care

A positive screening test may cause considerable anxiety for the parents. We can help them understand that a concerning developmental screen does not always indicate an abnormality nor does it provide a diagnosis or treatment plan. Rather it identifies areas in which a child’s development differs from same-age norms. If results are concerning, the child should be referred to an early intervention program and scheduled for a comprehensive developmental evaluation.

Specialty Care

Intervention for developmental delay need not wait for a comprehensive evaluation or a definitive diagnosis. Referral to a program that can both assist in the evaluation and provide services to help the child and parents is recommended when there is concern about developmental delay.
  • Early Intervention (see see all Early Intervention for Children with Disabilities/Delays services providers (49) in our database)
    • Families may self-refer to Early Intervention, but the clinician may send a referral form to provide specific information and to better coordinate care
    • The Early Intervention Program (EIP) may provide services such as developmental therapies, service coordination, family training, counseling, and home visits
    • The EIP will NOT perform a medical evaluation or other evaluations to establish a diagnosis of a specific developmental disability
    • A diagnosis of a specific developmental disability is NOT necessary for an EIP referral to be made or for services to begin
The evaluation of a child for developmental delay may involve some or all of the several specialists and disciplines noted below, depending on the specific findings at each stage of evaluation. Some communities will have a multi-disciplinary developmental clinic where all of the needed services will be available. If there are no such clinics nearby, the Medical Home may identify individual providers of the various components.
  • Comprehensive Evaluation
    • The goal of a comprehensive evaluation is to identify a specific developmental disability to aid in developing an appropriate treatment plan and to offer a prognosis for the child.
    • The developmental and medical components of the comprehensive evaluation should ideally be interdisciplinary. The table below describes the roles of the various disciplines in such an evaluation.
