M51.A0-M51.A5Primary Range
Intervertebral annulus fibrosus defects
This range includes codes for annular defects in the lumbar and lumbosacral regions, which are relevant for coding bulging discs due to annular tears.
Other intervertebral disc degeneration
This range is used for coding disc degeneration that may present as a bulging disc without specific annular defects.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| M51.A1 | Intervertebral annulus fibrosus defect, small, lumbar region | Use when MRI confirms a small annular defect in the lumbar region. |
|
| M51.A2 | Intervertebral annulus fibrosus defect, large, lumbar region | Use when MRI confirms a large annular defect in the lumbar region. |
|
| M51.36 | Other intervertebral disc degeneration, lumbar region | Use for degenerative bulging without specific annular defects. |

Primary ICD-10-CM Codes for bulging disc lumbar
Decision Criteria
clinical Criteria
- MRI shows annular defect <5 mm
documentation Criteria
- No nerve compression documented
Applicable To
- Small annular tears <5 mm without nerve compression
Excludes
- Herniated disc without myelopathy or radiculopathy
Clinical Validation Requirements
- MRI showing focal annular tears <5 mm
- Absence of nerve compression
Code-Specific Risks
- Confusing with herniation codes
- Omitting radiculopathy if present
Coding Notes
- Ensure documentation specifies annular defect and size.
M51.A2 - Intervertebral annulus fibrosus defect, large, lumbar region
Use when MRI confirms a large annular defect in the lumbar region.
Applicable To
- Defects ≥5 mm or involving >25% disc circumference
Excludes
- Herniated disc with radiculopathy
Clinical Validation Requirements
- MRI showing large annular defect
- Absence of herniation
Coding Notes
Document defect size and absence of herniation.
M51.36 - Other intervertebral disc degeneration, lumbar region
Use for degenerative bulging without specific annular defects.
Applicable To
- Age-related degeneration with diffuse bulging
Excludes
- Annular defects
Clinical Validation Requirements
- Imaging showing diffuse bulging without focal herniation
Coding Notes
Ensure documentation of degenerative changes.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Herniated disc without myelopathy/radiculopathy
M51.26Herniated disc with radiculopathy
M51.16Intervertebral annulus fibrosus defect, small, lumbar region
M51.A1Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Bulging Disc Lumbar to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M51.A1.
Impact
Clinical: Misclassification of disc condition., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Ensure MRI reports are detailed, Train staff on documentation standards
Impact
Reimbursement: Incorrect DRG assignment may occur., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation specifies bulging without focal protrusion.
Impact
Reimbursement: Potential underpayment for services rendered., Compliance: Failure to capture complete clinical picture., Data Quality: Incomplete patient records.
Mitigation Strategy
Document and code radiculopathy if nerve involvement is confirmed.
Impact
Using herniation codes for bulging discs can lead to audit findings.
Mitigation Strategy
Ensure documentation clearly differentiates between bulges and herniations.
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.
