About coding feeding disorder
The ICD-10-CM code for feeding disorder is R63.30 (Feeding difficulties, unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R63.30.
Within R63.3, choose R63.30 (unspecified) only when documentation doesn't support a more specific option: pediatric feeding disorder, acute (R63.31), pediatric feeding disorder, chronic (R63.32) and other feeding difficulties (R63.39).
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 640 (Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes with MCC, relative weight 1.3395) and DRG 641 (Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes without MCC, relative weight 0.7865), in MDC 10 (Endocrine, Nutritional and Metabolic 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.
