RxHCCHCC 148 — Mild Intellectual Disabilities
0.000What This Code Means
A developmental condition where a person has mild intellectual disability, meaning they have below-average intellectual functioning and adaptive behavior limitations but can often live independently with some support.
Coding Tips
- •Verify IQ testing results and adaptive functioning assessments are documented
- •Confirm the condition originated during the developmental period (before age 18)
Clinical Significance
Mild intellectual disability represents an IQ range of approximately 50-69, with the individual typically able to acquire practical skills and functional literacy but requiring some support in complex daily living tasks. These patients have increased healthcare needs related to communication barriers, difficulty understanding medical instructions, and higher rates of comorbid psychiatric and medical conditions. Proper coding supports appropriate care coordination.
Documentation Requirements
- ✓Provider documentation of intellectual disability with specification of severity as mild
- ✓Formal cognitive testing results (IQ approximately 50-69) or clinical assessment supporting the severity level
- ✓Documentation of adaptive functioning deficits in conceptual, social, or practical domains
- ✓Assessment of the impact on the patient's ability to manage their healthcare and daily living activities
- ✓Documentation of any comorbid conditions and current support services
