🦴 CPT 63075 — Discectomy, Anterior, With Decompression of Spinal Cord and/or Nerve Root(s); Cervical, Single Interspace

Quick Reference

wRVU: 19.11 | Global Period: 090 | Assistant Payable: Yes (Indicator 02) | Co-Surgeon: Yes (Indicator 02) | Bilateral Indicator: 0
Rule: CPT 63075 describes standalone anterior cervical discectomy with decompression performed without fusion. It is heavily audited because of its mandatory bundling relationship with cervical fusion codes: 63075 must never be reported alongside 22554 or 22551 at the same interspace. When discectomy and decompression are performed in conjunction with anterior cervical interbody fusion at the same level, CPT requires the combination code 22551. 63075 may only be separately reported with modifier -59 or -XS when performed at a distinct interspace/level from an ACDF.

📋 Clinical Description

CPT 63075 describes an anterior cervical procedure performed to decompress the spinal cord, nerve roots, or both by excising intervertebral disc tissue and bony osteophytes from a single cervical interspace.

The surgeon makes a transverse or longitudinal anterior neck incision, dissects through the avascular plane between the carotid sheath laterally and the trachea/esophagus medially, and exposes the anterior cervical spine. Fluoroscopy or radiopaque markers confirm the target interspace. The anterior longitudinal ligament and annulus fibrosus are incised, and the degenerate or herniated disc material is completely excised. Bony osteophytes along the posterior vertebral margins are resected using rongeurs, curettes, or a high-speed burr to achieve thorough canal and foraminal decompression.

Critical Clinical Distinction:

• Standalone Discectomy (63075): Performed purely for decompression without arthrodesis, interbody graft placement, or spinal instrumentation.
• ACDF (22551): If an interbody graft, cage, or structural allograft/autograft is inserted into the disc space to achieve fusion (arthrodesis), the entire procedure is coded as 22551 (which inherently includes the discectomy, decompression, and disc space preparation at that interspace).

🔬 Anatomical & Procedural Considerations

• Anatomic Boundaries: Covers the cervical spine from C2-C3 down to C7-T1.
• Structures Decompressed: Spinal cord (central canal) and exiting cervical nerve roots (neural foramina).
• Anterior Approach Specifics: Traverses anterior neck structures; risks include transient or permanent dysphagia, recurrent laryngeal nerve injury (vocal cord paresis), superior laryngeal nerve injury, esophageal perforation, and Horner syndrome.
• Single vs. Multiple Interspaces: CPT 63075 is reported once for the primary interspace. Additional cervical interspaces decompressed without fusion during the same session are reported using add-on code 63076.

✅ Procedure Includes

• Anterior surgical approach and exposure of the anterior cervical spine at the target interspace.
• Incision of the anterior longitudinal ligament and annulus fibrosus.
• Excision of herniated or degenerated intervertebral disc material.
• Resection of posterior osteophytes (osteophytectomy) for cord and/or root decompression.
• Foraminal decompression and nerve root neurolysis at the target interspace.
• Closure of operative layers and routine postoperative care within the 90-day global period.

❌ Excludes / Do Not Report Together

Excluded Code / Service	Description	Correct Coding Action / Reason
22551	Anterior cervical interbody fusion (ACDF), initial level	Do not report 63075 at the same level. CPT 22551 inherently includes discectomy, decompression, and disc space preparation.
22554	Anterior cervical arthrodesis, single interspace	Do not report 63075 + 22554 at the same level. Use combined code 22551 instead.
22845	Anterior spinal instrumentation, 2 to 3 vertebral bodies	Instrumentation is a component of fusion. Do not bill with standalone 63075.
20930 / 20931	Structural bone allograft for spine	Bone grafts/cages are fusion components. Do not bill with standalone 63075.
63076	Cervical discectomy, additional interspace	63076 is an add-on code; report alongside 63075 for each additional level decompressed.

Bilateral Billing Rules

CPT 63075 has a bilateral indicator of 0. Because the anterior approach provides access across the entire interspace to decompress both right and left nerve roots through a single midline exposure, appending modifier -50 is inappropriate and will result in claim rejection.

🏷️ Modifier Reference

Modifier	Name	When to Apply
-62	Two Surgeons	Applied when two surgeons (e.g., a neurosurgeon and an vascular/general surgeon for approach) act as co-surgeons. Co-surgeon indicator is 2 (permitted). Both surgeons must report 63075-62.
-59 / -XS	Distinct Procedural Service / Separate Structure	Applied when 63075 is performed at a different cervical interspace than an ACDF (22551) performed during the same session.
-22	Increased Procedural Services	Applied when documentation proves substantial additional surgical work (e.g., severe epidural scarring from prior surgery, extreme anatomical distortion, or re-operation).
-51	Multiple Procedures	Applied when 63075 is performed as a secondary procedure during the same surgical session as another non-bundled primary procedure.
-78	Unplanned Return to OR	Applied for an unplanned return to the operating room during the 90-day post-op period for a complication (e.g., postoperative hematoma evacuation).
-58	Staged or Related Procedure	Applied for a staged or related procedure performed by the same physician during the global period.

🏥 MS-DRG Considerations

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

DRG	Description	CC/MCC Requirement
MS-DRG 518	Back & Neck Procedures Except Spinal Fusion w MCC or Disc Device or Neurostimulator	Requires qualifying MCC or disc device insertion
MS-DRG 519	Back & Neck Procedures Except Spinal Fusion w CC	Requires qualifying CC
MS-DRG 520	Back & Neck Procedures Except Spinal Fusion w/o CC/MCC	Default when no CC/MCC is present

Note: If a spinal fusion (e.g. PCS 0RG10ZZ) is performed in addition to discectomy, the admission groups to MS-DRG 471, 472, or 473 (Cervical Spinal Fusion).

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

For inpatient hospital facility coding, CPT codes are not used; procedures are assigned using ICD-10-PCS.

PCS Code	Full Description	Section / Body System / Root Operation
0RB30ZZ	Excision of Cervical Vertebral Disc, Open Approach	Medical & Surgical (0) → Upper Joints (R) → Excision (B)
0RB34ZZ	Excision of Cervical Vertebral Disc, Percutaneous Endoscopic Approach	Medical & Surgical (0) → Upper Joints (R) → Excision (B)
00BT0ZZ	Excision of Spinal Meninges, Open Approach	Assigned if open excision/resection of spinal dura or meninges is performed

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

📝 Coding Examples

Example 1 — Standalone Anterior Cervical Discectomy (Outpatient / ASC)

Clinical Scenario:
A 51-year-old man presents with six months of progressive right arm pain, numbness, and weakness that has failed physical therapy and epidural steroid injections. MRI confirms a large right paracentral disc herniation at C5-C6 causing nerve root compression without cord signal change. He undergoes an anterior cervical discectomy with decompression of the right C6 nerve root at C5-C6; no interbody device, graft material, or fusion instrumentation is used, and the surgeon documents the interspace was left without arthrodesis.

CPT Coding: 63075 (Cervical, single interspace)
ICD-10-CM Coding: M50.121 (Cervical disc disorder with radiculopathy, mid-cervical region)
Compliance Note: Confirm the implant log and operating room inventory show no interbody cage, allograft, or anterior plate was placed. If a cage/graft were placed, the procedure would constitute an ACDF and must be billed as 22551.

---

Example 2 — Multi-Level Discectomy Without Fusion

Clinical Scenario:
A 63-year-old woman with progressive gait instability, hand clumsiness, and hyperreflexia is found to have severe cord compression at C4-C5 and C5-C6 from disc herniations and posterior osteophytes. She undergoes anterior cervical discectomy with cord decompression at C4-C5 and C5-C6. No spinal fusion or hardware is implanted. Intraoperative neurophysiological monitoring is performed throughout by an independent neurophysiologist.

CPT Coding:
- 63075 (Cervical discectomy, single interspace — primary interspace)
- 63076 (Cervical discectomy, each additional interspace — add-on code for second level)
ICD-10-CM Coding: M50.021 (Cervical disc disorder with myelopathy, mid-cervical region)
Compliance Note: Add-on code 63076 is exempt from modifier -51. Both interspaces must be explicitly described in the operative narrative.

---

Example 3 — Distinct-Level Discectomy and ACDF

Clinical Scenario:
A 48-year-old male undergoes an anterior cervical interbody fusion (ACDF) at C5-C6 for symptomatic spondylotic myelopathy. At the adjacent C3-C4 level, the surgeon performs an anterior discectomy with nerve root decompression for a distinct herniated disc, but does not perform fusion at C3-C4.

CPT Coding:
- 22551 (ACDF, C5-C6 — primary fusion procedure)
- 63075--XS (Anterior cervical discectomy, C3-C4 — distinct structure/level)
Compliance Note: Append modifier -XS (or -59) to 63075 to document that the discectomy was performed at a different anatomical interspace from the fusion code 22551. Without the modifier, NCCI edits will bundle 63075 into 22551.

⚠️ Common Coding Pitfalls & Audit Red Flags

1. Unbundling 63075 with 22551 at the Same Level:

   • Violation: Reporting 63075 alongside 22551 (or 22554) for the same interspace.
   • Correction: 22551 includes discectomy, decompression, and disc space preparation. Never report 63075 at the fusion level.

2. Inappropriate Use of Modifier -50:

   • Violation: Appending modifier -50 to 63075 for bilateral nerve root decompression.
   • Correction: CPT 63075 has a Bilateral Indicator of 0. The code inherently covers decompression across the entire interspace via the anterior approach.

3. Billing 63075 When Instrumentation or Interbody Grafts Are Placed:

   • Violation: Coding 63075 + 22845 + 20930 for a procedure documented as a discectomy.
   • Correction: Insertion of interbody structural grafts/cages and plates constitutes an anterior cervical interbody fusion (ACDF), which requires code 22551.

4. Inpatient Procedure Coding Error (CPT vs PCS):

   • Violation: Submitting CPT 63075 on an inpatient hospital facility claim or using incorrect PCS code 00BT0ZZ as the primary discectomy code.
   • Correction: Inpatient hospital facility claims require ICD-10-PCS code 0RB30ZZ for open cervical discectomy.
