Within R62.5, choose R62.50 (Unspecified lack of expected normal physiological development in childhood) only when documentation doesn't support a more specific option: failure to thrive (child) (R62.51), short stature (child) (R62.52) and other lack of expected normal physiological development in childhood (R62.59).

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.
