CPT Code 96112: Developmental test administration billing guide

Key Takeaways

CPT Code 96112 covers the first hour of developmental test administration using standardized instruments, assessing fine/gross motor skills, language, cognition, social functioning, memory, and executive function.

Only physicians and other qualified health care professionals (QHPs) may bill 96112 directly; occupational therapists and speech-language pathologists qualify depending on their state scope of practice.

96113 is the required add-on code for each additional 30 minutes beyond the first hour; it cannot be billed without a primary 96112 on the same claim.

Practice management software like Pabau helps developmental testing practices track time-based units, attach covered ICD-10 codes, and reduce CPT 96112 claim denials.

CPT Code 96112 is the billable code for the first hour of developmental test administration using standardized instruments. It has been the correct code since January 1, 2019, when the American Medical Association (AMA) retired 96111 and split developmental testing into two time-based codes: 96112 and its add-on, 96113.

This guide covers the official descriptor, qualified providers, time requirements, the 96112/96113 pairing, Medicare coverage, reimbursement rates, and the documentation a clean claim requires.

The code sits within the Central Nervous System Assessments section of the CPT manual. It’s time-based, provider-specific, and carries documentation requirements that differ from standard evaluation and management codes.

CPT Code 96112: Official description and clinical scope

The full 96112 CPT code description reads: Developmental test administration (including assessment of fine and/or gross motor, language, cognitive level, social, memory and/or executive functions by standardized developmental instruments when performed), by physician or other qualified health care professional, with interpretation and report; first hour.

Three elements of that descriptor drive the billing rules. First, the assessment must use standardized developmental instruments. Informal observation alone does not qualify. Second, the code bundles the test administration with interpretation and the written report. Third, it covers the first hour of testing time specifically.

Common standardized instruments reported under 96112 include the Autism Diagnostic Observation Schedule (ADOS), the Bayley Scales of Infant and Toddler Development, the Vineland Adaptive Behavior Scales, and similar validated tools.

Practices serving children with autism spectrum disorder (ASD), developmental delay, or behavioral disorders will use this code most frequently. Practices specializing in ADHD assessment and management also encounter 96112 when standardized cognitive or behavioral instruments are administered during an evaluation visit.

Why the 96111 CPT code was replaced

Before January 1, 2019, developmental testing was reported under CPT 96111. The AMA retired 96111 and created 96112 and 96113 to add time-based granularity and clarify that interpretation and report writing are bundled into the work. Claims still using 96111 for dates of service on or after January 1, 2019 are rejected by every payer.

Covered diagnoses: ICD-10 codes used with 96112

Medical necessity for CPT Code 96112 requires a supporting ICD-10 diagnosis. Payers apply Local Coverage Determinations (LCDs) and National Coverage Determinations (NCDs) to evaluate whether the diagnosis justifies standardized developmental testing. The table below lists the most commonly accepted ICD-10 codes, though coverage policies vary by payer and state Medicaid program.

For deeper coding guidance, see F84.0 for autistic disorder and R62.50 for developmental delay, unspecified.

Who can bill CPT code 96112: Qualified providers and supervision rules

The CPT descriptor specifies “physician or other qualified health care professional.” In practice, qualified providers include:

• Physicians (MD, DO) with relevant specialty training
• Psychologists (PhD, PsyD) licensed to administer standardized instruments
• Developmental-behavioral pediatricians
• Occupational therapists (OT) and occupational therapy assistants, depending on state scope of practice
• Speech-language pathologists (SLP), depending on state scope of practice
• Nurse practitioners and physician assistants in some payer-specific contexts

Scope of practice rules vary by state. Confirm with your state licensing board before billing 96112 under a discipline not listed in your payer contract.

According to the American Occupational Therapy Association (AOTA), occupational therapists who administer standardized developmental instruments may report this code where their state practice act permits. For 96112 CPT code occupational therapy claims specifically, the testing must fall within the therapist’s licensed scope and be recognized in the payer contract.

Occupational therapists who also perform standalone OT evaluations in the same episode of care should review 97165 billing rules separately.

Multidisciplinary psychology practices and developmental practices often have several provider types administering these tests. Billing correctly requires knowing which provider type is credentialed with each payer and whether incident-to rules apply.

Incident-to billing

Under Medicare’s incident-to rules, a non-physician practitioner may bill under a supervising physician’s NPI if specific supervision and documentation requirements are met. Incident-to billing for developmental testing carries compliance risk. The supervising physician must be present in the office suite (direct supervision), and the service must be integral to the physician’s treatment plan. Practices should consult a compliance expert before applying incident-to billing to 96112.

CPT Code 96112 vs 96113: Time requirements and add-on billing

CPT Code 96112 covers the first hour. The 96113 CPT code is the add-on for each additional 30 minutes of testing time. The two codes work together. You cannot bill 96113 without a primary 96112 on the same date of service.

For a 90-minute session, bill 96112 x1 and 96113 x1. For a 120-minute session, bill 96112 x1 and 96113 x2. Time counting must reflect actual face-to-face testing time, not the total appointment slot.

Interpretation and report-writing time is bundled into the code and does not add billable units. A patient booking form that captures expected test duration up front helps front-desk staff schedule an accurate appointment slot.

Developmental testing for children with autism and speech delay often runs 90 minutes or longer when the ADOS or a similar multi-domain instrument is used. Accurate start and stop times for the testing portion create a clean record if a payer reviews the claim.

Practices offering these services through occupational therapy software workflows benefit from time-stamped session records that capture testing time separately from pre-session review.

Multidisciplinary practices billing other time-based procedure codes during the same visit, such as 97124 for therapeutic exercise, should apply the same start-and-stop-time discipline across every code on the claim.

96112 and 96113 are distinct from psychological testing code 96136 and neuropsychological testing codes 96132 and 96133. Confirm the descriptor before selecting between these code families. You can also review comparable time-based developmental billing patterns in the ADHD screening CPT codes guide, which covers adjacent codes in the behavioral health coding family.

96110 CPT code vs 96112: Screening or full developmental testing

The 96110 CPT code covers developmental screening with a standardized instrument, such as the Ages and Stages Questionnaire or the Denver Developmental Screening Test, that a caregiver or clinician completes quickly. CPT Code 96112 covers developmental testing. That means the hands-on administration and interpretation of an in-depth instrument by a clinician. Billing 96112 for a screening-level encounter is a frequent denial trigger.

Reach for the 96110 CPT code when the encounter is a short, scored screen layered onto another visit. Use 96112 when a qualified professional administers a full standardized battery and writes an interpretive report. The 96127 CPT code follows the same screening logic for emotional and behavioral instruments like the Vanderbilt or PHQ.

Higher-complexity cognitive work uses a separate family. The 96116 CPT code reports a neurobehavioral status exam, while the 96132 CPT code and 96133 CPT code cover neuropsychological testing evaluation for the first and each additional hour. Match the code to the work performed so the claim reflects the service delivered.

Reimbursement rates and Medicare coverage for 96112

Medicare generally covers CPT Code 96112 when the testing is medically necessary, under standard Medicare Physician Fee Schedule (MPFS) rules. Reimbursement amounts are set annually by the Medicare Physician Fee Schedule.

CMS Medicare Coverage Database Article A57481 is a related billing and coding reference tied to psychological and neuropsychological testing coverage. It cross-references 96110, 96112, 96113, and 96127 only to clarify that developmental testing is a separate code family from the psychological and neuropsychological testing codes.

96112 CPT code reimbursement is set by the MPFS. Current figures should be verified each calendar year using the CMS Physician Fee Schedule lookup tool, because rates adjust with the annual conversion factor update.

For context, New York State Medicaid’s Office of Mental Health (OMH) assigned 96112 an Ambulatory Patient Group (APG) weight of 0.8275, effective July 1, 2019. That APG weight is a state Medicaid rate-setting figure, not a national Medicare RVU. Verify current-year MPFS values separately before referencing any specific dollar amount in your practice’s financial modeling.

Medicaid coverage varies by state. Most state Medicaid programs cover developmental testing for pediatric beneficiaries, but prior authorization requirements differ. Commercial payers generally follow CMS guidance but may require pre-authorization for sessions longer than 60 minutes, especially when 96113 is billed multiple times in a single encounter.

Telehealth eligibility

CPT Code 96112 and its add-on, 96113, appear on CMS’s Medicare Telehealth Services List as permanent audio-video telehealth codes. They are not eligible for audio-only billing. Telehealth eligibility still depends on current CMS policy, the applicable policy period, and payer-specific telehealth rules.

For Medicare professional telehealth claims, append modifier 95 with the appropriate telehealth place-of-service code, POS 02 or POS 10, rather than the retired GT modifier. CMS removed GT from Medicare Part B professional claims in 2018, and GT now applies only to Critical Access Hospital Method II institutional claims.

Most commercial payers still accept modifier 95 for synchronous telehealth. Practices using Pabau’s telehealth software can document compliant video sessions for remote developmental evaluations.

Documentation requirements and common billing errors

A clean 96112 claim requires documentation that satisfies three categories: provider qualification, testing specifics, and time. Missing any one of these makes the claim vulnerable to denial or post-payment audit.

Required documentation elements

• Provider credential: Name, NPI, and professional license of the clinician who administered the test
• Instrument name: Full name of each standardized tool administered (e.g., Bayley-4, Vineland-3, ADOS-2)
• Start and stop times: Actual face-to-face testing time, not the scheduled appointment window
• Diagnosis with clinical justification: Supporting ICD-10 code(s) with a brief statement of medical necessity
• Interpretation and report: Written summary of findings, including domain scores and clinical implications
• Treatment plan linkage: Connection between test results and the patient’s ongoing care plan

Practices using mental health EMR or occupational therapy EMR platforms can structure note templates to capture all six elements automatically, so incomplete records don’t reach the billing team. Between visits, behavior tracking sheets give families a simple way to log symptoms that support the interpretation section of the report.

Common billing errors to avoid

• Using retired code 96111: All dates of service on or after January 1, 2019 must use 96112/96113. Payers reject 96111 outright.
• Billing 96113 without 96112: The add-on cannot stand alone. Always bill 96112 as the primary code first.
• Counting report-writing time: Time for interpretation and report writing is bundled into the RVU. Only face-to-face test administration time counts toward the 60-minute threshold.
• Missing the standardized instrument requirement: Informal developmental observation without a named standardized tool does not support 96112. Use CPT 99213-99215 E/M codes for non-standardized developmental surveillance.
• Unbundling with psychological testing codes: Verify NCCI edits before billing 96112 alongside 96136 or 96116 on the same date. Some combinations require a modifier to override the bundling edit. Others are not separately reportable.
• Wrong telehealth modifier: Use modifier 95 with telehealth POS code 02 or 10 for Medicare professional claims, and modifier 95 for most commercial payers. GT is retired for Medicare Part B professional claims and now applies only to Critical Access Hospital Method II institutional billing.

Speech-language pathology and occupational therapy practices should also verify that their payer contracts explicitly allow 96112 billing by their discipline. Payers sometimes restrict the code to physicians and psychologists even when the CPT descriptor’s “qualified health care professional” language is broader.

SLP practices can cross-reference billing workflows against the patterns described in Pabau’s speech therapy software documentation, and a SOAP notes template keeps session documentation consistent across providers.

Getting CPT 96112 claims paid

Developmental testing claims fail most often due to incomplete time documentation and provider eligibility confusion. CPT Code 96112 rewards practices that capture start and stop times, name the standardized instrument, and pair the code correctly with 96113 for longer sessions.

Pabau’s claims management software helps developmental testing practices structure documentation workflows so that every 96112 claim leaves the practice with complete time records, linked ICD-10 codes, and the interpretation report attached.
