🦴 CPT 63076 — Discectomy, Anterior, With Decompression of Spinal Cord and/or Nerve Root(s), Including Osteophytectomy; Cervical, Each Additional Interspace


Quick Reference

wRVU: 3.94 | Global Period: ZZZ | Assistant Payable: Yes (Indicator 02) | Co-Surgeon: Yes (Indicator 02) | Bilateral Indicator: 0 | Modifier -51 Exempt: Yes
Rule: CPT 63076 is an add-on code carrying a ZZZ global period. It must be reported in conjunction with primary code 63075 for each additional cervical interspace decompressed without fusion. It can never be billed as a standalone line item. If interbody fusion (ACDF) is performed at the additional interspace, report 22552 instead of 63076.


📋 Clinical Description

CPT 63076 describes anterior decompression and excision of intervertebral disc tissue, including posterior osteophytectomy, at each additional cervical interspace beyond the initial level reported under primary code 63075.

Through the extended anterior cervical approach, the surgeon exposes the additional interspace, performs annulus incision, and excises herniated or degenerated disc material. Bony spurs and posterior vertebral osteophytes compressing the spinal cord or exiting nerve roots are removed using high-speed burrs or curettes to achieve thorough canal and foraminal decompression.

Critical Billing & Regulatory Rules:

  • Primary Code Requirement: CPT 63076 can only be reported alongside 63075. CPT coding guidelines explicitly state: “Use 63076 in conjunction with 63075.”
  • Decompression vs. Fusion Distinction:
    • Standalone Discectomy Add-On (63076): Assigned when decompression alone is performed at an additional level without interbody graft, cage, or fusion hardware.
    • ACDF Add-On (22552): If an interbody graft/cage is placed to achieve arthrodesis at the additional level, report 22552 (which inherently includes the discectomy and decompression at that level) instead of 63076.
  • Level-by-Level Specificity: The operative narrative must explicitly identify each individual interspace treated (e.g., C4-C5, C5-C6). Generic statements such as “multilevel decompression” do not satisfy documentation requirements for multiple units.

🔬 Anatomical & Procedural Considerations

  • Anatomic Scope: Cervical spine interspaces from C2-C3 through C7-T1.
  • Target Structures: Central spinal canal (spinal cord) and neural foramina (excitatory cervical nerve roots) at secondary or tertiary levels.
  • Osteophytectomy Component: Removal of posterior vertebral body osteophytes at the additional level is bundled into 63076 and cannot be reported separately.
  • Unit Calculation: Report 1 unit of 63076 per additional decompressed interspace. (e.g., 2-level decompression = 1 unit of 63075 + 1 unit of 63076; 3-level decompression = 1 unit of 63075 + 2 units of 63076).

✅ Procedure Includes

  • Extended anterior surgical exposure to the additional cervical interspace.
  • Incision of the annulus fibrosus and excision of degenerated/herniated disc material at the additional level.
  • Posterior osteophytectomy for central canal and foraminal nerve root decompression.
  • Intraoperative fluoroscopy or radiopaque marker verification of the additional interspace performed by the operating surgeon.
  • Wound closure of the shared anterior surgical exposure.

❌ Excludes / Do Not Report Together

Excluded Code / ServiceDescriptionCorrect Coding Action / Reason
22552Anterior cervical interbody fusion (ACDF), each additional interspaceDo not report 63076 for an interspace receiving fusion. Use 22552 instead.
22551 / 22554Anterior cervical interbody fusion, initial levelNever report 63076 at the same interspace as a fusion code. 22551 includes the discectomy.
22845 / 22846Anterior spinal instrumentationInstrumentation is a component of spinal fusion; do not report with standalone decompression add-on 63076.
63075Cervical discectomy, single interspacePrimary procedure code. 63076 is billed in addition to 63075, never in place of it.

NCCI & Bundling Alert

Under CMS NCCI edits, anterior discectomy codes (63075 / 63076) are bundled into anterior cervical interbody fusion codes (22551 / 22552 / 22554) when performed at the same interspace. 63076 should only be assigned for interspaces where decompression was performed without fusion.

🏥 MS-DRG Considerations

Under the CMS Inpatient Prospective Payment System (IPPS), non-fusion anterior cervical discectomy procedures group to MDC 08 (Diseases & Disorders of the Musculoskeletal System & Connective Tissue) under the non-fusion surgical back and neck DRG triad:

DRGDescriptionCC/MCC Requirement
MS-DRG 518Back & Neck Procedures Except Spinal Fusion w MCC or Disc Device or NeurostimulatorRequires qualifying MCC or disc device insertion
MS-DRG 519Back & Neck Procedures Except Spinal Fusion w CCRequires qualifying CC
MS-DRG 520Back & Neck Procedures Except Spinal Fusion w/o CC/MCCDefault when no CC/MCC is present

Note: If spinal fusion (e.g., ACDF) is performed during the same admission, the inpatient encounter shifts to MS-DRG 471, 472, or 473 (Cervical Spinal Fusion).


🔧 ICD-10-PCS Equivalents (Inpatient Facility Coding)

Inpatient facility coding utilizes ICD-10-PCS rather than CPT codes.

PCS CodeFull DescriptionSection / Body System / Root Operation
0RB30ZZExcision of Cervical Vertebral Disc, Open ApproachMedical & Surgical (0) → Upper Joints (R) → Excision (B)
0RT30ZZResection of Cervical Vertebral Disc, Open ApproachMedical & Surgical (0) → Upper Joints (R) → Resection (T)

PCS Character Breakdown — 0RB30ZZ

  • 0: Medical and Surgical Section
  • R: Upper Joints Body System
  • B: Excision (Cutting out or off, without replacement, a portion of a body part)
  • 3: Cervical Vertebral Disc
  • 0: Open Approach
  • Z: No Device
  • Z: No Qualifier

Inpatient PCS Guideline Note: Under ICD-10-PCS, each distinct cervical disc excised is coded separately using 0RB30ZZ if required by health system coding rules or facility unit guidelines.


📝 Coding Examples

Example 1 — Multi-Level Standalone Anterior Cervical Discectomy

Clinical Scenario:
A 58-year-old male with progressive neck pain and bilateral C6 and C7 radiculopathy undergoes anterior cervical discectomy with nerve root decompression at C5-C6 and C6-C7. No interbody fusion device, bone graft, or fixation plate is placed at either level.

CPT Coding:
- 63075 (Cervical discectomy, C5-C6 — primary interspace)
- 63076 (Cervical discectomy, C6-C7 — add-on code for second interspace)
ICD-10-CM Coding: M50.121 (Cervical disc disorder with radiculopathy, mid-cervical region)
Compliance Note: Do not append modifier -51 to 63076. Both interspaces must be distinctly documented in the operative record.


Example 2 — Multi-Level Discectomy Performed by Co-Surgeons

Clinical Scenario:
A patient with severe cervical spondylotic myelopathy undergoes 3-level anterior cervical discectomy and spinal cord decompression at C3-C4, C4-C5, and C5-C6. A neurosurgeon and an orthopedic spine surgeon act as co-surgeons throughout the entire decompressive procedure. No fusion is performed.

CPT Coding:
- 63075--62 (C3-C4 primary interspace, co-surgeon)
- 63076--62 (C4-C5 additional interspace, co-surgeon)
- 63076--62 (C5-C6 additional interspace, co-surgeon — 2nd unit)
ICD-10-CM Coding: M50.021 (Cervical disc disorder with myelopathy, mid-cervical region)
Compliance Note: Both co-surgeons must submit claims with modifier -62 appended to 63075 and each unit of 63076.


Example 3 — Combined Session: ACDF at Primary Level and Decompression-Only at Secondary Level

Clinical Scenario:
A 50-year-old female undergoes an anterior cervical interbody fusion (ACDF) at C5-C6 using a PEEK cage and plate for focal instability. At the adjacent C4-C5 level, the surgeon performs an anterior discectomy and nerve root decompression, but places no cage or fusion hardware at C4-C5.

CPT Coding:
- 22551 (ACDF, C5-C6 — primary fusion procedure)
- 63075--XS (Anterior cervical discectomy, C4-C5 — distinct structure/level)
Compliance Note: Notice that CPT 63076 is not used here because 63075 was not billed for the primary level (ACDF 22551 was billed instead). CPT 63075 is assigned for the C4-C5 decompression with modifier -XS (or -59) appended to show it was performed at a separate interspace from the fusion.


⚠️ Common Coding Pitfalls & Audit Red Flags

  1. Reporting 63076 Without Primary Code 63075:

    • Violation: Submitting 63076 as a standalone code or paired with 22551.
    • Correction: CPT parenthetical rules require 63076 to be reported in conjunction with 63075.
  2. Reporting 63076 for Fused Interspaces:

    • Violation: Coding 63076 for an additional interspace where an interbody cage/graft was placed for fusion.
    • Correction: An additional interspace receiving fusion must be coded as 22552, not 63076.
  3. Inappropriate Application of Modifier -51:

    • Violation: Appending modifier -51 to add-on code 63076.
    • Correction: As an add-on code, 63076 is inherently exempt from modifier -51.
  4. Inappropriate Application of Bilateral Modifiers (-50 / -RT / -LT):

    • Violation: Appending -50 or -RT/-LT to 63076.
    • Correction: Bilateral Indicator is 0. Midline cervical interspaces are not lateral paired structures.
  5. Inpatient Hospital Facility Coding Error (CPT vs PCS):

    • Violation: Billing CPT 63076 on an inpatient facility UB-04 claim or using joint code 0RB20ZZ instead of disc code 0RB30ZZ.
    • Correction: Inpatient facility claims require ICD-10-PCS code 0RB30ZZ (Excision of Cervical Vertebral Disc, Open Approach).
