R62.59

Other lack of expected normal physiological development in childhood

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

Code Description

ICD-10 R62.59 is a billable code used to indicate a diagnosis of other lack of expected normal physiological development in childhood.

Key Diagnostic Point:

R62.59 is used to classify cases where a child exhibits a lack of expected normal physiological development that does not fit into more specific categories. This may include developmental delays in physical growth, cognitive function, or social skills that are not attributable to a specific diagnosis. Symptoms may manifest as failure to thrive, delayed milestones in motor skills, or atypical behavioral patterns. Clinical findings may include abnormal growth parameters, such as weight and height percentiles falling below expected ranges, or developmental assessments indicating significant delays. Laboratory findings may be non-specific but could include metabolic panels that rule out underlying conditions. The code is essential for capturing cases where developmental issues are present but lack a clear etiology, allowing for appropriate management and intervention strategies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes
  • Overlap with other developmental disorders
  • Need for comprehensive documentation
  • Potential for misclassification

Audit Risk Factors

  • Inadequate documentation of developmental assessments
  • Failure to specify the nature of the developmental delay
  • Misuse of the code for conditions with specific diagnoses
  • Lack of follow-up documentation on developmental progress

Documentation Requirements

Detailed history of developmental milestones, physical examination findings, and any relevant laboratory results.

Common Clinical Scenarios

Evaluation of a child presenting with poor growth or delayed milestones during routine check-ups.

Billing Considerations

Ensure that all relevant developmental assessments are documented to support the diagnosis.

Emergency Medicine

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of developmental issues, improving the ability to track and manage these conditions effectively. R62.59 provides a necessary option for cases that do not fit neatly into other categories.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of developmental issues, improving the ability to track and manage these conditions effectively. R62.59 provides a necessary option for cases that do not fit neatly into other categories.
