Key Information: ICD-10 code for hyperreflexia

Essential facts and insights about Hyperreflexia

The ICD-10 code for hyperreflexia is R29.2, used for abnormal reflexes without a definitive diagnosis.

Primary ICD-10-CM Code for hyperreflexia

Abnormal reflex
Billable Code

Decision Criteria

clinical Criteria

  • Presence of hyperreflexia without a known cause

coding Criteria

  • Underlying condition should be coded first if known

Applicable To

  • Hyperreflexia

Excludes

  • Hyperactive gag reflex (J39.2)
  • Abnormal pupillary reflex (H57.0)

Clinical Validation Requirements

  • Reflex testing confirms hyperreflexia (e.g., 3+ patellar reflexes bilaterally with clonus)
  • No definitive neurological diagnosis established

Code-Specific Risks

  • Using R29.2 when a more specific code is available could lead to audits.

Coding Notes

  • R29.2 should not be used as a principal diagnosis if a definitive diagnosis exists.

Ancillary Codes

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

Sequelae of cerebrovascular disease

I69.3
Use when hyperreflexia is due to a stroke.

Differential Codes

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

Multiple sclerosis

G35
Use G35 when hyperreflexia is a manifestation of multiple sclerosis.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Hyperreflexia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R29.2.

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 specific reflex grading and associated findings.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use J39.2 for hyperactive gag reflex.

Impact

Failure to code underlying conditions first.

Mitigation Strategy

Review coding guidelines for sequencing rules.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Hyperreflexia, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Hyperreflexia

Use these documentation templates to ensure complete and accurate documentation for Hyperreflexia. These templates include all required elements for proper coding and billing.

Neurological examination for hyperreflexia

Specialty: Neurology

Required Elements

  • Reflex grading
  • Presence of clonus
  • Associated upper motor neuron signs

Example Documentation

Patient exhibits 4+ patellar reflexes with sustained clonus and positive Babinski sign.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Increased reflexes noted.
Good Documentation Example
3+ bilateral patellar reflexes with spread to adductors, sustained clonus (4 beats) in right ankle.
Explanation
The good example provides specific reflex grading and associated findings.
