92523 CPT Code: Speech and Language Evaluation Guide

The 92523 CPT code reports a combined evaluation of speech sound production and language comprehension and expression — the most complete of the speech-language assessment codes. It covers articulation, phonology, apraxia, and dysarthria on the speech-sound side and both receptive and expressive language on the other, in a single untimed evaluation. Most full SLP evaluations land here, which is exactly why payers watch how it is paired and how often it is billed.

What is the 92523 CPT code? 92523 is the Current Procedural Terminology code for the evaluation of speech sound production — articulation, phonological process, apraxia, or dysarthria — together with the evaluation of language comprehension and expression, reported as a single untimed assessment.

Undeny's Take

92523 exists because the old split codes did not match clinical reality. When a child is evaluated for language, they are usually evaluated for speech sound production in the same session — so the combined code became the default, and that is fine. The errors come at the edges. Billing 92523 more than once a day, stacking it with the speech-sound-only code 92522 for the same evaluation, or treating it as a timed service all generate denials. It is one untimed unit per evaluation, per day. Pick 92523 when you assessed both speech sound and language; drop to 92522 when you only assessed speech sound. Match the code to what you actually evaluated and the claim holds.

What 92523 Covers

92523 covers a comprehensive speech-language evaluation with two components: speech sound production — articulation, phonological processes, apraxia, and dysarthria — and language comprehension and expression, meaning both receptive and expressive language. It is the combined member of the speech-evaluation family, used for new-client assessments such as a child with a speech delay or an adult after a stroke, when both speech sound and language are examined.

Why 92523 Is a Single Untimed Unit

92523 is not a time-based code — you report one unit for the evaluation regardless of how long it takes, and it should be billed only once per day per patient. Selecting it is about scope, not minutes: it applies when both speech sound and language were evaluated, while the speech-sound-only evaluation (92522) applies when language was not assessed. Reimbursement follows each payer's fee schedule on the Physician Fee Schedule; confirm your contracted rate or use the CPT estimator.

Modifiers and Pairings

GN — service furnished under an outpatient speech-language-pathology plan of care.
Do not report 92523 together with 92522 for the same evaluation; 92523 already includes the speech-sound component.
Treatment that follows the evaluation is reported separately with the speech-treatment code, not bundled into 92523.

Common 92523 Denials

Billed more than once on the same day for the same patient.
Reported alongside 92522 for one evaluation, double-counting the speech-sound component.
Billed as a timed service with multiple units rather than a single untimed evaluation.
Missing plan-of-care modifier (GN) or documentation supporting both components were evaluated.

Frequently Asked Questions

What does 92523 evaluate?

92523 evaluates both speech sound production — articulation, phonology, apraxia, and dysarthria — and language comprehension and expression, covering receptive and expressive language. It is the combined speech-language evaluation used when both areas are assessed.

What is the difference between 92522 and 92523?

92522 evaluates speech sound production only, while 92523 adds the evaluation of language comprehension and expression. Use 92523 when you assessed both speech sound and language, and 92522 when language was not part of the evaluation.

Is 92523 a timed code?

No. 92523 is a single untimed evaluation billed once per day per patient, so the duration does not change the unit. You report one evaluation regardless of how long it takes.

Can I bill 92523 and 92522 together?

No. 92523 already includes the speech-sound-production component that 92522 covers, so reporting both for the same evaluation double-counts that work and is a denial trigger.
