- Billable — Valid for Submission
- Not Chronic
R47.82 is a billable ICD-10-CM diagnosis code for fluency disorder in conditions classified elsewhere. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026). The code is a manifestation code that cannot be reported as the principal diagnosis. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. Coders also document this condition as fluency disorder due to Parkinson disease. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Nervous system signs and symptoms.

Inclusion Terms
- Stuttering in conditions classified elsewhere
Code First
- underlying disease or condition, such as:
- Parkinson's disease G20
Type 1 Excludes
- adult onset fluency disorder F98.5
- childhood onset fluency disorder F80.81
- fluency disorder (stuttering) following cerebrovascular disease (I69. with final characters -23)
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Questions About R47.82Overview

Yes. This is a billable ICD-10-CM code, specific enough to report fluency disorder in conditions classified elsewhere on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can R47.82 be a principal diagnosis?
No. This is a manifestation code: fluency disorder in conditions classified elsewhere describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
What is the ICD-9 equivalent of R47.82?
Under the General Equivalence Mappings, fluency disorder in conditions classified elsewhere converts to ICD-9-CM 784.52 (flncy dsord cond elsewhr). The mapping is a direct match.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
