About coding communication disorder
The ICD-10-CM code for communication disorder is F80.9 (Developmental disorder of speech and language, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F80.9.
Within F80, choose F80.9 (Developmental disorder of speech and language, unspecified) only when documentation doesn't support a more specific option: Phonological disorder (F80.0), Expressive language disorder (F80.1), mixed receptive-expressive language disorder (F80.2), speech and language development delay due to hearing loss (F80.4) and other developmental disorders of speech and language (F80.8).
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.
