Excludes

  • Nocturnal enuresis (R32)

Clinical Validation Requirements

  • Documented episodes of urination during the night
  • Bladder diary showing nocturnal voiding frequency

Code-Specific Risks

  • Incorrectly using as primary code when an underlying condition is identified

Coding Notes

  • Ensure nocturia is not coded as primary if an underlying cause is identified.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Frequency of micturition

R35.0
Use when documenting urinary frequency alongside nocturia.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Benign prostatic hyperplasia with lower urinary tract symptoms

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Nocturia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R35.1.

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.

Mitigation Strategy

Use structured templates for nocturia documentation., Ensure all nocturnal voids are quantified and timed.

Impact

Reimbursement: May lead to incorrect DRG assignment and affect reimbursement., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Identify and code the underlying condition first, then add R35.1 as secondary.

Impact

Incorrect sequencing of nocturia and underlying conditions.

Mitigation Strategy

Educate coders on proper sequencing rules and use of additional codes.

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.
