| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E10.9 | Type 1 diabetes mellitus without complications | Use when Type 1 diabetes is documented without any complications. |
|
| E10.65 | Type 1 diabetes mellitus with hyperglycemia | Use when hyperglycemia is documented as a complication of Type 1 diabetes. |
|
| T85.614A | Mechanical complication of insulin pump, initial encounter | Use when there is a documented mechanical failure of an insulin pump. |

E10.65 - Type 1 diabetes mellitus with hyperglycemia
Use when hyperglycemia is documented as a complication of Type 1 diabetes.
Applicable To
- Type 1 diabetes with hyperglycemia
Excludes
- Type 2 diabetes mellitus with hyperglycemia (E11.65)
Clinical Validation Requirements
- Documented hyperglycemia with glucose >200 mg/dL

Excludes
- Non-mechanical complications of insulin pump
Clinical Validation Requirements
- Documented mechanical failure of insulin pump
Coding Notes
Ensure linkage between mechanical failure and underdosing.

T38.3x6xADocumentation & Coding Risks
Avoid these common documentation and coding issues when documenting Insulin-Dependent Diabetes to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E10.9.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Review medication list during each visit, Ensure insulin use is documented in the medical record
Impact
Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate data reporting and analysis.
Mitigation Strategy
Ensure documentation specifies Type 1 diabetes for E10 codes.
Impact
Reimbursement: May affect risk adjustment factor calculations., Compliance: Incomplete coding for diabetes management., Data Quality: Incomplete data for treatment analysis.
Mitigation Strategy
Always add Z79.4 when long-term insulin use is documented.
Impact
Failure to document and code complications accurately.
Mitigation Strategy
Implement regular chart audits and coder training.
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.
