I15.9 - Secondary hypertension, unspecified
Use when hypertension is secondary but the specific cause is not documented.
Applicable To
- Secondary hypertension
Excludes
- Essential hypertension (I10)

- No specific cause identified
Coding Notes
Ensure secondary hypertension is suspected but not specified.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

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 Unspecified Hypertension to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I10.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Thoroughly investigate and document potential secondary causes., Use appropriate secondary hypertension codes when applicable.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate health records and statistics.
Mitigation Strategy
Use R03.0 for elevated BP without a formal diagnosis of hypertension.
Impact
Risk of incorrect coding due to lack of specificity in documentation.
Mitigation Strategy
Ensure detailed documentation of hypertension type and any related conditions.
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.
