| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| F90.0 | Attention-deficit hyperactivity disorder, predominantly inattentive type | Use when inattention is the primary symptom without significant hyperactivity. |
|
| F90.1 | Attention-deficit hyperactivity disorder, predominantly hyperactive-impulsive type | Use when hyperactivity and impulsivity are the primary symptoms without significant inattention. |
|
| F90.2 | Attention-deficit hyperactivity disorder, combined type | Use when both inattention and hyperactivity-impulsivity are present. |
|
| F90.9 | Attention-deficit hyperactivity disorder, unspecified type | Use when ADHD is diagnosed but the specific subtype cannot be determined. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Attention Deficit Hyperactivity Disorder
Primary ICD-10-CM Codes for attention deficit hyperactivity disorder
Decision Criteria
clinical Criteria
- Presence of ≥6 inattentive symptoms
documentation Criteria
- Symptoms documented in multiple settings
Clinical Validation Requirements
- ≥6 inattentive symptoms in children or ≥5 in adults
- Symptoms present in two or more settings
- Symptoms persist for at least 6 months
Code-Specific Risks
- Misclassification if hyperactivity is present
- Inadequate documentation of symptom settings
Coding Notes
- Ensure documentation specifies the inattentive symptoms and their impact on daily functioning.
F90.1 - Attention-deficit hyperactivity disorder, predominantly hyperactive-impulsive type
Use when hyperactivity and impulsivity are the primary symptoms without significant inattention.
Applicable To
- Predominantly hyperactive-impulsive presentation
Excludes
- F90.0
- F90.2
Clinical Validation Requirements
- ≥6 hyperactive-impulsive symptoms in children or ≥5 in adults
- Symptoms present in two or more settings
- Symptoms persist for at least 6 months
Coding Notes
Ensure documentation specifies the hyperactive-impulsive symptoms and their impact on daily functioning.
F90.2 - Attention-deficit hyperactivity disorder, combined type
Use when both inattention and hyperactivity-impulsivity are present.
Applicable To
- Combined presentation
Clinical Validation Requirements
- ≥6 inattentive and ≥6 hyperactive-impulsive symptoms in children or ≥5 of each in adults
- Symptoms present in two or more settings
- Symptoms persist for at least 6 months
Coding Notes
Ensure documentation specifies both inattentive and hyperactive-impulsive symptoms and their impact on daily functioning.
F90.9 - Attention-deficit hyperactivity disorder, unspecified type
Use when ADHD is diagnosed but the specific subtype cannot be determined.
Applicable To
- ADHD NOS
Excludes
- F90.0
- F90.1
- F90.2
Clinical Validation Requirements
- Symptoms present but insufficient information to classify subtype
- Symptoms present in two or more settings
- Symptoms persist for at least 6 months
Coding Notes
Use as a last resort when specific subtypes cannot be determined.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Encounter for routine child health examination with abnormal findings
Z00.121Encounter for routine child health examination without abnormal findings
Z00.129Encounter for screening for certain developmental disorders in childhood
Z13.4Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Attention Deficit Hyperactivity Disorder to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code F90.0.
Impact
Clinical: Inaccurate diagnosis, Regulatory: Non-compliance with ICD-10 guidelines, Financial: Claim denials
Mitigation Strategy
Include symptom duration in documentation, Use standardized assessment tools
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreased accuracy in patient records.
Mitigation Strategy
Ensure thorough assessment and documentation to identify specific subtypes.
Impact
Reimbursement: Potential denial of claims., Compliance: Failure to meet clinical documentation standards., Data Quality: Incomplete patient records.
Mitigation Strategy
Document symptoms in at least two settings (e.g., home and school).
Impact
High risk of audit if F90.9 is overused without justification.
Mitigation Strategy
Ensure thorough documentation and assessment to identify specific subtypes.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
