R63.3Feeding difficulties

R63.3 is the ICD-10-CM diagnosis code for feeding difficulties. 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 a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within R63 (symptoms and signs concerning food and fluid intake), R63.3 is specifically for feeding difficulties. Related codes cover Anorexia (R63.0), Polydipsia (R63.1), Polyphagia (R63.2), abnormal weight loss (R63.4), abnormal weight gain (R63.5), Underweight (R63.6) and other symptoms and signs concerning food and fluid intake (R63.8).

To report this condition, pick the subcode that matches the documentation: R63.30 (unspecified), R63.31 (acute), R63.32 (chronic) and R63.39 (difficulties).

The conditions in its Excludes2 note aren't part of R63.3, but may be coded alongside it if the patient has both: eating disorders (F50.-), feeding problems of newborn (P92.-) and infant feeding disorder of nonorganic origin (F98.2-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2022 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 783.3 (feeding difficulties and mismanagement).
