| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R74.8 | Abnormal levels of other serum enzymes | Use when elevated amylase is present without a definitive diagnosis of pancreatitis. |
|
| K85.9 | Acute pancreatitis, unspecified | Use when acute pancreatitis is confirmed by clinical and imaging criteria. |

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 Amylase
Primary ICD-10-CM Codes for amylase
Decision Criteria
clinical Criteria
- Amylase levels elevated but lipase normal and no imaging evidence of pancreatitis.
coding Criteria
- No definitive diagnosis of pancreatitis present.
Applicable To
- Elevated amylase
Excludes
- Acute pancreatitis (K85.9)
Clinical Validation Requirements
- Amylase 1-3x ULN without clinical evidence of pancreatitis
Code-Specific Risks
- Using as principal diagnosis when a more specific diagnosis is available.
Coding Notes
- Ensure documentation supports the absence of pancreatitis when using R74.8.
K85.9 - Acute pancreatitis, unspecified
Use when acute pancreatitis is confirmed by clinical and imaging criteria.
Applicable To
- Acute pancreatitis
Excludes
- Chronic pancreatitis (K86.1)
Clinical Validation Requirements
- Lipase ≥3x ULN
- Imaging evidence of pancreatitis
Coding Notes
Ensure all three ACG criteria are documented for acute pancreatitis.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Chronic pancreatitis
K86.1Differential 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 Amylase to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R74.8.
Impact
Clinical: May lead to misdiagnosis., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.
Mitigation Strategy
Ensure imaging results are included in the patient record., Use standardized templates for documentation.
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Could lead to coding audits and denials., Data Quality: Impacts accuracy of clinical data.
Mitigation Strategy
Use K85.9 when pancreatitis is confirmed.
Impact
Using R74.8 as a principal diagnosis when pancreatitis is present.
Mitigation Strategy
Ensure documentation supports the absence of pancreatitis.
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.
