R62.50

Unspecified lack of expected normal physiological development in childhood

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R62.50 is a billable code used to indicate a diagnosis of unspecified lack of expected normal physiological development in childhood.

Key Diagnostic Point:

R62.50 refers to a condition characterized by a lack of expected normal physiological development in children, which can manifest as delayed growth, failure to thrive, or other developmental delays. This code is used when the specific cause of the developmental delay is not identified or classified elsewhere. Symptoms may include reduced height and weight percentiles, lack of motor skills, speech delays, and social interaction difficulties. Abnormal clinical findings may include low body mass index (BMI), abnormal growth patterns on growth charts, and developmental screening results indicating delays. The underlying causes can vary widely, including genetic disorders, nutritional deficiencies, chronic illnesses, or psychosocial factors. A thorough clinical evaluation is essential to identify contributing factors and guide appropriate interventions.

Audit Risk Factors

  • Insufficient documentation of growth parameters
  • Failure to specify the developmental delay
  • Inadequate clinical evaluation notes
  • Misuse of unspecified codes when specific conditions exist

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding options, but it has also increased the complexity of coding for developmental issues. Coders must be diligent in ensuring that R62.50 is used appropriately and supported by documentation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding options, but it has also increased the complexity of coding for developmental issues. Coders must be diligent in ensuring that R62.50 is used appropriately and supported by documentation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding options, but it has also increased the complexity of coding for developmental issues. Coders must be diligent in ensuring that R62.50 is used appropriately and supported by documentation.
