Sequelae of cerebrovascular disease

This range includes codes for hemiparesis as a sequela of cerebrovascular disease, such as stroke.

Key Information: ICD-10 code for hemiparesis

Essential facts and insights about Hemiparesis

The ICD-10 code for hemiparesis following a cerebral infarction is I69.351 for right dominant side.

Primary ICD-10-CM Code for hemiparesis

Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side
Billable Code

Decision Criteria

clinical Criteria

  • Documented right-sided weakness post-stroke with dominance specified

documentation Criteria

  • Lack of dominance specification defaults to right as dominant

Applicable To

  • Residual right-sided weakness due to previous stroke

Excludes

  • Acute cerebrovascular disease (I63.x)

Clinical Validation Requirements

  • MRI/CT confirming prior infarction
  • Neurological exam documenting right-sided weakness

Code-Specific Risks

  • Incorrect dominance documentation
  • Lack of temporal relationship to stroke

Coding Notes

  • Ensure documentation specifies laterality and dominance for accurate coding.

Ancillary Codes

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

Personal history of transient ischemic attack (TIA), and cerebral infarction without residual deficits

Z86.73
Use when documenting resolved hemiparesis with no current deficits.

Differential Codes

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

Unspecified neurological neglect syndrome

R29.5
Use R29.5 for acute phase neurological symptoms not yet classified as sequelae.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Hemiparesis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I69.351.

Impact

Clinical: Inaccurate clinical records., Regulatory: Non-compliance with coding guidelines., Financial: Potential for incorrect billing and reimbursement.

Mitigation Strategy

Use standardized templates., Educate clinicians on documentation importance.

Impact

Reimbursement: Incorrect coding can lead to overpayments or denials., Compliance: Non-compliance with CMS guidelines., Data Quality: Inaccurate patient records and risk adjustment scores.

Mitigation Strategy

Code I69.3xx when weakness is directly tied to prior stroke

Impact

Lack of dominance documentation can lead to audit failures.

Mitigation Strategy

Implement mandatory fields in EHR for dominance.

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 Hemiparesis, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Hemiparesis

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

Chronic hemiparesis post-stroke

Specialty: Neurology

Required Elements

  • Affected side
  • Dominance
  • Temporal relationship to stroke
  • Functional impact

Example Documentation

Patient presents with residual right-sided weakness due to left MCA infarct from 2023. Dominant side affected, limiting ADLs.

Examples: Poor vs. Good Documentation

Poor Documentation Example
History of stroke with weakness.
Good Documentation Example
Residual left non-dominant hemiparesis from 01/2024 thalamic infarct.
Explanation
The good example specifies the side, dominance, and links the weakness to a specific stroke event.
