CPT Code 96110: Developmental screening billing guide 2026

Key Takeaways

CPT Code 96110 covers developmental screening using a standardized, validated instrument with scoring and documentation – it does not apply to informal observation or casual questioning.

Modifier 25 attaches to the same-day E/M or preventive medicine code, not to 96110 itself; billing it on the wrong code is one of the most common denial triggers.

Age limits and frequency rules vary significantly by payer; Medicare does not typically cover 96110 as a standalone service, while Medicaid policies differ state by state.

Pabau’s digital forms and claims management software help practices capture screening data and submit 96110 claims accurately from a single workflow.

CPT Code 96110: Definition, description, and clinical use

CPT Code 96110 is a billable code that covers developmental screening using a standardized, validated instrument, with scoring and documentation. It does not apply to informal observation or casual questioning – the screening must use a recognized tool that is scored and recorded in the patient’s record.

The American Medical Association (AMA) defines CPT Code 96110 as: Developmental screening (e.g., developmental milestone survey, speech and language delay screen), with scoring and documentation, per standardized instrument. That last phrase is doing most of the work. Without a validated, scored instrument and clinical documentation, the code does not apply.

CPT Code 96110 sits within the Central Nervous System Assessments/Tests section of the CPT code set, specifically the Developmental and Behavioral Screening and Testing subsection (96110-96113). It is the entry-level code in that family – briefer and less intensive than CPT Code 96112, which requires a trained administrator and covers a broader battery of developmental domains.

When to use CPT Code 96110

96110 applies when a provider administers a formal developmental screening tool, scores it according to the instrument’s instructions, and documents the results in the patient record to support clinical decision-making. Common clinical scenarios include:

• Well-child visits: routine developmental surveillance using ASQ or M-CHAT at 9, 18, and 24-30 month checkups per AAP guidelines
• Early intervention referral evaluation: screening a child with suspected developmental delay prior to referral
• Autism-specific screening: administering M-CHAT-R/F at 18 and 24 months as recommended by the American Academy of Pediatrics (AAP)
• ADHD behavioral screening: using validated ADHD rating scales to initiate a diagnostic workup
• Longitudinal monitoring: tracking developmental progress for children already enrolled in early intervention services

The code is not appropriate for informal developmental questions asked during a routine exam, general clinical observation without a scored tool, or chart review without direct patient interaction. Using digital intake forms to pre-populate screening instruments before the encounter helps ensure the screening is captured correctly and consistently across every visit.

Approved screening instruments for CPT Code 96110

Payers require that the tool used is standardized, validated, and appropriate to the patient’s age and clinical presentation. No single national list defines every acceptable instrument, but the following are broadly recognized across commercial, Medicaid, and AAP guidance.

Using multiple instruments in the same visit is allowed. According to guidance from pedstestonline.com, a practice using PEDS, PEDS:DM, and M-CHAT-R/F together may bill 96110 three times on the same date (96110 x 3), provided each instrument is scored and documented separately. Confirm this approach with your specific payer before billing, as not all plans follow this interpretation.

CPT Code 96110 billing guidelines and modifier usage

Most CPT 96110 denials trace back to one of three errors: applying the modifier to the wrong code, failing to document the instrument used, or billing 96110 without a same-day E/M when the payer requires one. Getting the billing logic right protects both the claim and any post-payment audit.

Modifier 25 and same-day E/M billing

CPT Code 96110 is frequently billed on the same date as a well-child visit (preventive medicine E/M) or a problem-focused office visit. When that happens, Modifier 25 is required on the E/M or preventive medicine code, not on 96110. Modifier 25 signals to the payer that the E/M is a separate, distinct service from the developmental screening.

The claim line structure should look like this:

• Line 1: Preventive E/M code (e.g., 99392) with Modifier 25
• Line 2: 96110 without any modifier (unless a payer specifically requires one)

Appending Modifier 25 to 96110 itself is incorrect and will typically result in a denial or reduced payment. The AAP’s coding fact sheet, referenced across multiple authoritative sources, confirms this modifier placement. Review your HIPAA compliance practices for medical offices to ensure documentation supporting Modifier 25 is maintained in the record.

Documentation requirements

The clinical record must include the name of the screening instrument, the date administered, the score obtained, and the provider’s interpretation or clinical action taken based on results. Documentation that says only “developmental screening performed” without naming the tool or recording a score does not support billing CPT Code 96110.

A structured note should capture: instrument name, version, score per domain (where applicable), total score or risk category, and next steps (e.g., monitoring at next visit, referral to early intervention, or parental education provided). Practices using a mental health EMR or pediatric practice management system with built-in screening templates can standardize this documentation across all providers.

CPT Code 96110 reimbursement rates and payer-specific rules

Reimbursement for CPT Code 96110 varies by payer, geographic locality, and contract terms. The figures below reflect general 2026 benchmarks; verify current rates using the CMS Physician Fee Schedule lookup tool or your payer-specific fee schedule before billing.

For a precise 2026 RVU lookup and geographic locality adjustment, the PCC free 2026 RVU/RBRVS calculator imports CMS fee schedule data and accounts for location multipliers. This is particularly useful for practices billing across multiple sites or states.

When billing for ADHD screening billing requirements alongside 96110, confirm whether your payer bundles behavioral screening instruments under a single unit of 96110 or allows separate reporting per instrument administered.

CPT Code 96110 age limits and frequency restrictions

Age limits for CPT Code 96110 are one of the most payer-variable aspects of billing this code. There is no single universal rule: commercial plans, state Medicaid programs, and managed care organizations each set their own parameters. Assuming a universal age cutoff is a fast path to denials.

State Medicaid examples

Two well-documented state-specific rules illustrate how much variation exists:

• California Medi-Cal: The Department of Health Care Services (DHCS) clarified via bulletin 20-687 that general developmental screenings using CPT Code 96110 are restricted to patients through age 6 years.
• Texas Medicaid: Blue Cross and Blue Shield of Texas (BCBSTX) and Superior Health Plan restrict 96110 to patients through age 6 years outside of the Texas Health Steps program. Within Texas Health Steps, different frequency rules may apply.

Other states take a broader view and allow 96110 up to age 21 within Medicaid EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) benefit structures. Check your state Medicaid agency’s billing manual or fee schedule before assuming any universal upper age limit applies to your patient population.

Frequency limits

Frequency rules are similarly payer-specific. Many plans limit 96110 to once per rolling 12-month period outside of specific screening schedules tied to well-child visit protocols.

Some state Medicaid programs align frequency with AAP Bright Futures guidelines, which recommend developmental screening at 9, 18, and 24-30 months, plus autism-specific screening at 18 and 24 months. Billing 96110 more frequently than the payer allows without documentation of clinical necessity is a common audit trigger.

Practices seeing children with known developmental concerns or those enrolled in early intervention should document the medical necessity for any screening that falls outside standard well-child visit intervals. For practices also managing ICD-10 codes for autistic disorder alongside developmental screenings, accurate cross-referencing between the screening result and the diagnosis code strengthens medical necessity documentation.

Related CPT codes: 96112, 96113, and 96127

CPT Code 96110 is the least intensive code in the developmental and behavioral screening family. Knowing when to use the related codes prevents both undercoding (leaving revenue on the table) and overcoding (billing a more intensive service than what was delivered).

96110 vs 96112: When to use each

The critical distinction is who administers the test and how long it takes. CPT Code 96110 covers brief, standardized screeners – the kind a parent fills out in the waiting room or a provider completes in five to ten minutes. CPT Code 96112 requires a trained examiner conducting a systematic evaluation across multiple developmental domains, typically taking at least 60 minutes.

Using 96112 for a service that was actually a brief screening tool administered at a well-child visit is overcoding. Conversely, using 96110 for a full developmental testing battery lasting an hour or more leaves significant reimbursement uncaptured. Document the time spent and the instruments used to support whichever code you bill. For guidance on similar behavioral health billing patterns, see related behavioral health CPT codes and how they interact with screening and assessment services.

96110 and 96127 on the same date

96127 covers emotional and behavioral assessments (such as PHQ-A for adolescent depression or the Pediatric Symptom Checklist). It is distinct from 96110 and can be billed on the same date when a provider administers both a developmental screening and a separate emotional/behavioral instrument. Each must be independently scored and documented. Some payers bundle these under a single unit; review your payer’s MUE (medically unlikely edit) policy before billing both on the same date.

For practices managing pediatric developmental workflows alongside autism spectrum coding, the clinical guidance on autism and speech delay assessment provides context on how diagnostic and screening codes interact in a complete patient workup. Practices running multi-provider pediatric settings benefit from claims management software that flags bundling conflicts automatically before claims leave the practice.

For practices managing ADHD evaluations alongside developmental screenings, see how Vanderbilt ADHD Rating Scale scoring intersects with the 96110-96127 billing decision, particularly when both instruments are administered at the same well-child visit. Practices running ADHD-focused services can also explore dedicated ADHD clinic software to streamline screening workflows and documentation requirements across both code types.

Conclusion

CPT Code 96110 denials almost always come down to the same issues: a modifier on the wrong code, documentation that names a screening but not a standardized instrument, or a billing pattern that exceeds payer-specific age or frequency limits. None of these are hard to fix once the rules are clear.
