About coding learning specific disorder
The ICD-10-CM code for learning specific disorder is F81.9 (Developmental disorder of scholastic skills, unspecified). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F81.9.
Within F81, choose F81.9 (Developmental disorder of scholastic skills, unspecified) only when documentation doesn't support a more specific option: specific reading disorder (F81.0), Mathematics disorder (F81.2) and other developmental disorders of scholastic skills (F81.8).
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.
