About R63.31

R63.31 is the ICD-10-CM diagnosis code for pediatric feeding disorder, acute. It belongs to category R63 (symptoms and signs concerning food and fluid intake), block R50-R69 (general symptoms and signs) 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 R63.3 (feeding difficulties), R63.31 is specifically for pediatric feeding disorder, acute. Related codes cover unspecified (R63.30), 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.

The Medicare Code Editor expects this diagnosis only for patients age 0 through 17; other ages trigger an age-conflict edit.

It was added in FY2022, effective October 1, 2021.
