Questions About F80.0Overview
What is the ICD-10 code for phonological disorder?
The ICD-10-CM code for phonological disorder is F80.0 (sometimes written as F800). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is F80.0 (Specific developmental disorders of speech and language) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report phonological disorder on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does F80.0 group to?
When phonological 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 F80.0 be reported with R47.01?
Not as a rule. The Excludes1 note on F80.0 lists "speech articulation impairment due to aphasia NOS (R47.01)". 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 F80.0?
Under the General Equivalence Mappings, phonological disorder converts to ICD-9-CM 315.39 (speech/language dis NEC). The mapping is approximate, so confirm the match fits the documentation.
