Spondylolisthesis, lumbar region
Billable Code

Decision Criteria

clinical Criteria

  • Imaging shows ≥3mm posterior displacement.

documentation Criteria

  • Documentation specifies 'retrolisthesis' and vertebral level.

Applicable To

  • Retrolisthesis of lumbar spine

Excludes

  • Anterolisthesis

Clinical Validation Requirements

  • Imaging confirmation (X-ray/MRI) showing ≥3mm posterior vertebral displacement

Code-Specific Risks

  • Confusing with anterolisthesis, which requires a different code.

Coding Notes

  • Ensure documentation specifies vertebral level and direction of slippage.

Ancillary Codes

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

Low back pain

M54.5
Use for unspecified low back pain without confirmed structural cause.

Radiculopathy, lumbar region

M54.16
Use when neurological symptoms like leg numbness are present.

Differential Codes

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

Cervical disc displacement

M50.2-
Use M43.16 for lumbar retrolisthesis, not cervical conditions.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Lumbar Retrolisthesis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M43.16.

Impact

Clinical: Leads to misdiagnosis and inappropriate treatment., Regulatory: Fails to meet documentation standards., Financial: Potential for denied claims due to lack of specificity.

Mitigation Strategy

Use specific terms like 'retrolisthesis' with measurements., Ensure imaging supports documentation.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate clinical data recording.

Mitigation Strategy

Verify imaging and documentation specify posterior displacement.

Impact

Coding M43.16 without imaging confirmation.

Mitigation Strategy

Ensure all codes are supported by imaging reports.

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.

Documentation Templates for Lumbar Retrolisthesis

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

Chronic low back pain with retrolisthesis

Specialty: Orthopedics

Required Elements

  • Vertebral level
  • Direction of slippage
  • Imaging findings
  • Symptoms

Example Documentation

Patient presents with chronic low back pain radiating to left leg. MRI reveals 4mm retrolisthesis of L4 over L5 with moderate foraminal stenosis and L5 nerve root compression.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Low back pain with possible slipped vertebra.
Good Documentation Example
MRI reveals Grade 1 retrolisthesis (3.2mm) of L4 over L5 with moderate foraminal stenosis and L5 nerve root compression.
Explanation
The good example provides specific imaging findings and clinical correlation.
