F05Primary Range
Delirium due to known physiological cause
Primary range for delirium, often used when confusion is due to an acute medical condition.
Disorientation, unspecified
Used for non-specific confusion when no underlying cause is identified.
Encephalopathy, unspecified
Used when confusion is due to global brain dysfunction without acute delirium features.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| F05 | Delirium due to known physiological cause | Use when confusion is acute, with a known physiological trigger. |
|
| R41.0 | Disorientation, unspecified | Use when confusion is non-specific and no underlying cause is identified. |

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

Excludes
- Delirium (F05)
Clinical Validation Requirements
- Normal labs and imaging
- Documentation ruling out delirium
Coding Notes
Avoid using R41.0 if a specific cause of confusion is documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Increased Confusion to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code F05.
Impact
Clinical: Ambiguous diagnosis, Regulatory: Non-compliance with coding guidelines, Financial: Potential reimbursement denials
Mitigation Strategy
Clarify if AMS is acute or chronic., Link to specific etiology.
Impact
Reimbursement: Incorrect DRG assignment, Compliance: Potential audit risk, Data Quality: Inaccurate clinical data
Mitigation Strategy
Use F05 with the underlying cause (e.g., hyponatremia).
Impact
Incorrect sequencing or lack of physiological cause documentation.
Mitigation Strategy
Ensure thorough documentation of underlying causes.
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.
