Questions About F80.1Overview
What is the ICD-10 code for expressive language disorder?
The ICD-10-CM code for expressive language disorder is F80.1 (sometimes written as F801). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is F80.1 (Specific developmental disorders of speech and language) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report expressive language disorder on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does F80.1 group to?
When expressive language disorder is the principal diagnosis on an inpatient stay, it groups to MS-DRG 886 (behavioral and Developmental Disorders), which carries a relative weight of 1.6455. Higher weights mean higher Medicare reimbursement.
Can F80.1 be reported with F80.2?
Not as a rule. The Excludes1 note on F80.1 lists "mixed receptive-expressive language disorder (F80.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of F80.1?
Under the General Equivalence Mappings, expressive language disorder converts to ICD-9-CM 315.31 (expressive language dis). The mapping is a direct match.
