This document discusses feeding problems that can occur in newborns during the first 28 days of life and provides corresponding ICD-10 codes for specific issues. It lists examples of problems such as difficulty feeding at breast, slow feeding, underfeeding, overfeeding, and regurgitation. ICD-10 codes are given for each issue to document feeding problems and treatment in medical notes. Feeding problems that occur after 28 days should be coded differently.
