About R47.89

R47.89 is the ICD-10-CM diagnosis code for other speech disturbances. It belongs to category R47 (speech disturbances, not elsewhere classified), block R47-R49 (symptoms and signs involving speech and voice) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R47.8, choose R47.89 (Other speech disturbances) only when documentation doesn't support a more specific option: Slurred speech (R47.81) and fluency disorder in conditions classified elsewhere (R47.82).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 784.59 (other speech disturbance) and V41.4 (problems with voice production).
