- Paraplegia without specified cause
Excludes
- Paraplegia due to specific spinal cord injury
Clinical Validation Requirements
- Complete loss of motor function
- Spinal cord injury or chronic progressive myelopathy
Coding Notes
Ensure documentation specifies the absence of a specific cause.
I69.xxx - Sequelae of cerebrovascular disease
Use for post-stroke weakness with specific laterality and dominance.
Applicable To
- Post-stroke weakness
Excludes
- Acute stroke
Clinical Validation Requirements
- Temporal relationship to CVA
- Unilateral/bilateral weakness with NIHSS ≥1
- Imaging-confirmed infarct
Coding Notes
Ensure documentation specifies the stroke event and laterality.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Bilateral Leg Weakness to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M62.81.
Impact
Clinical: May lead to incorrect treatment plans., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation Strategy
Always document laterality, Use templates to ensure completeness
Impact
Reimbursement: Incorrect coding can lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data representation of patient condition.
Mitigation Strategy
Use I69.351 + R29.898 if <1 year post-CVA
Impact
Using generalized weakness codes instead of specific post-stroke codes.
Mitigation Strategy
Ensure documentation clearly links weakness to stroke event.
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.
