About F80.89

F80.89 is the ICD-10-CM diagnosis code for other developmental disorders of speech and language. It belongs to category F80 (specific developmental disorders of speech and language), block F80-F89 (pervasive and specific developmental disorders) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within F80.8, choose F80.89 (Other developmental disorders of speech and language) only when documentation doesn't support a more specific option: childhood onset fluency disorder (F80.81) and social pragmatic communication disorder (F80.82).

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 886 (Behavioral and Developmental Disorders, relative weight 1.8678), in MDC 19 (Mental Diseases and Disorders), 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 315.39 (other developmental speech or language disorder).
