R62.5Other and unspecified lack of expected normal physiological development in childhood

R62.5 is the ICD-10-CM diagnosis code for other and unspecified lack of expected normal physiological development in childhood. It belongs to category R62 (lack of expected normal physiological development in childhood and adults), 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 R62, choose R62.5 (Other and unspecified lack of expected normal physiological development in childhood) only when documentation doesn't support a more specific option: delayed milestone in childhood (R62.0) and adult failure to thrive (R62.7).

To report this condition, pick the subcode that matches the documentation: R62.50 (childhood), R62.51 ((child)), R62.52 ((child)) and R62.59 (childhood).

Don't report R62.5 together with the conditions in its Excludes1 note: HIV disease resulting in failure to thrive (B20) and physical retardation due to malnutrition (E45).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
