| I30.9 | Acute pericarditis, unspecified | Use when low voltage QRS is due to pericardial effusion. |
|
| R94.31 | Abnormal electrocardiogram [ECG] [EKG] | Use as an ancillary code when low voltage QRS is noted without a definitive underlying condition. |

Applicable To
- Cardiac amyloidosis with low voltage QRS
Excludes
- Non-cardiac amyloidosis
Clinical Validation Requirements
- Serum free light chains abnormal
- Myocardial wall thickness >12mm on echocardiogram
- QRS amplitude ≤5mm in limb leads
Code-Specific Risks
- Misclassification if not confirmed by biopsy or imaging
Coding Notes
- Ensure documentation includes specific measurements and confirmatory tests.
I30.9 - Acute pericarditis, unspecified
Use when low voltage QRS is due to pericardial effusion.
Applicable To
- Pericardial effusion with low voltage QRS
Excludes
- Chronic pericarditis
Clinical Validation Requirements
- Pericardial effusion on echocardiogram
- QRS amplitude ≤10mm in precordial leads
Coding Notes
Document specific echocardiographic findings and measurements.
R94.31 - Abnormal electrocardiogram [ECG] [EKG]
Use as an ancillary code when low voltage QRS is noted without a definitive underlying condition.
Applicable To
- Low voltage QRS without definitive diagnosis
Excludes
- Normal ECG findings
Clinical Validation Requirements
- Documented low voltage QRS without identified cause
Coding Notes
Should not be used as a primary diagnosis.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Abnormal electrocardiogram [ECG] [EKG]
R94.31Differential 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 Low Voltage QRS Complex to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E85.4.
Impact
Clinical: Inadequate clinical assessment, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials
Mitigation Strategy
Always document specific QRS measurements.
Impact
Reimbursement: Denials due to lack of primary diagnosis, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate representation of patient condition
Mitigation Strategy
Always pair with a primary diagnosis code for the underlying condition.
Impact
Improper use of R94.31 as a primary code.
Mitigation Strategy
Ensure R94.31 is used only as a secondary code.
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.
