- Autonomic neuropathy with cold intolerance
Clinical Validation Requirements
- Documented autonomic neuropathy
- Abnormal QST or LASCA results
Coding Notes
Document autonomic testing results.
T33.5 - Frostbite of other and unspecified sites
Use when cold intolerance is a sequela of frostbite.
Applicable To
- Sequelae of frostbite with cold intolerance
Clinical Validation Requirements
- History of frostbite
- Persistent cold sensitivity
Coding Notes
Sequence frostbite code first if symptoms persist.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

R68.83Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Cold Intolerance to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R68.89.
Impact
Clinical: Inadequate assessment of symptom severity., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to insufficient documentation.
Mitigation Strategy
Ensure CISS score is recorded at each visit.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use R68.89 for cold intolerance without fever.
Impact
Inadequate documentation of QST or LASCA results.
Mitigation Strategy
Ensure all test results are clearly documented in the patient's record.
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.
