What Does CPT Code 0220T Mean?

CPT code 0220T is a Category III temporary code describing the placement of a posterior intrafacet implant in the thoracic spine. This procedure involves the surgical implantation of one or more allograft dowels, wedges, or synthetic spacers into the thoracic facet joints under image guidance (fluoroscopy or CT navigation), performed unilaterally or bilaterally at a single thoracic level. The implant expands and stabilizes the facet joint space, addressing pain from degenerative changes, facet-oriented back pain, or trauma in the thoracic vertebral region. As a Category III code, 0220T is designated for data collection and emerging technology and may have variable payer coverage.

Key Code Attributes:

• Category: III (Temporary - Emerging Technology)
• Code Type: Surgical - spine/facet procedure
• Primary Setting: Hospital operating room or ambulatory surgery center (ASC) with image guidance capability
• Provider Type: Orthopedic spine surgeon or neurosurgeon
• Anesthesia Type: General anesthesia (typically)
• billed under CPT 00620 (thoracic spine)
• Status: Active Category III code (verified through 2026)
• Typical Patient Population: Adults with thoracic facet joint syndrome, thoracic facet arthrosis, or instability of the thoracic posterior elements not responsive to conservative management
• Reimbursement: Variable - determined by individual payer policies; many Category III codes are considered investigational by commercial payers
• No RVUs: Category III codes are not assigned RVUs in the Medicare Physician Fee Schedule (MPFS)

What Services and Procedures Does CPT Code 0220T Cover?

CPT 0220T covers the surgical placement of a posterior intrafacet implant specifically in the thoracic spine at a single level. The procedure involves accessing the thoracic facet joint through a posterior approach, preparing the joint surface, and inserting an implant (dowel, allograft, or synthetic device) to maintain joint distraction and stability, with imaging guidance included. Covered Procedures and Surgical Indications:

• Posterior intrafacet implant for thoracic facet arthropathy
• Thoracic facet distraction and stabilization for facet-oriented back pain
• Thoracic facet joint arthrodesis using intrafacet dowel or wedge
• Posterior thoracic facet stabilization using allograft implant
• Image-guided thoracic intrafacet implant for chronic thoracic pain
• Facet wedge or dowel fusion (intrafacet implant) at a thoracic level
• Stabilization of thoracic facet joints in segmental instability
• Single-level thoracic intrafacet implant performed unilaterally or bilaterally
• Minimally invasive posterior thoracic intrafacet distraction
• Thoracic facet joint replacement using synthetic device
• Adjacent segment facet stabilization after a thoracic fusion Procedural Steps (Typical):

1. Patient positioned prone with the thoracic spine exposed
2. Posterior midline, paramedian, or percutaneous access at the target thoracic level
3. Image guidance (fluoroscopy or navigation) confirms the target thoracic facet joint
4. Facet joint capsule incision and preparation of the joint surfaces
5. Placement of the intrafacet implant (allograft/bone dowel or synthetic wedge) into the facet joint
6. Position confirmed under image guidance
7. Bone graft or synthetic device packed as needed
8. Wound closure in layers Excluded Procedures: | Excluded Procedure | Correct Code | Rationale | |-------------------|-------------|-----------| | Thoracic decompression laminectomy | 63046/63077 | Decompression without implant placement | | Posterior thoracic fusion with instrumented pedicle screws | 22610 | Instrumented arthrodesis | | Anterior thoracic interbody fusion | 22556 | Anterior approach interbody fusion | | Interspinous process distraction device (lumbar) | 22867 | Different device and region - not 0220T | | Facet joint injection (therapeutic thoracic) | 64489 | Injection - not surgical implant | | Lumbar facet implant | 0221T | Different anatomic region (lumbar) | | Cervical facet implant | 0219T | Different anatomic region (cervical) |

When Is CPT Code 0220T the Right Code to Use?

Step-by-Step Code Selection Criteria:

1. Confirm thoracic spine location

• 0220T is specifically for a single level in the thoracic spine
• Not for the cervical spine (use 0219T) or lumbar spine (use 0221T)
• Confirm the level is thoracic (T1-T12)

2. Verify intrafacet implant (not fusion, not decompression)

• The procedure must involve placement of an implant INTO the facet joint
• Not a traditional instrumented fusion (no pedicle screws leading to arthrodesis)
• Not a decompression (no laminectomy or foraminotomy alone)
• The intrafacet implant may include imaging, bone graft, or synthetic device placement

3. Confirm Category III code use

• 0220T is a temporary code for data collection
• Report is for a single level; for an additional level use +0222T
• Report with all applicable Category I codes that are performed concurrently

4. Verify single level

• The base 0220T is single level
• For each additional segment (cervical, thoracic, or lumbar) add +0222T
• Do not append -22 for multiple levels; use the add-on code

How Does CPT 0220T Differ From Related Codes?

Code	Procedure	Category	Typical Surgical Examples
0219T	Posterior intrafacet implant, cervical	III	Single-level cervical facet implant
0220T	Posterior intrafacet implant, thoracic	III	Single-level thoracic facet implant
0221T	Posterior intrafacet implant, lumbar	III	Single-level lumbar facet implant
+0222T	Each additional level	III	Additional surgical level beyond the first
22555	Anterior cervical discectomy and fusion	I	Anterior approach ACDF fusion
22610	Posterior lumbar fusion	I	Posterior instrumented fusion
22858	Cervical disc arthroplasty	I	Anterior disc replacement

What Documentation Is Required to Support CPT 0220T?

Preoperative Documentation:

• History of chronic thoracic or thoracic facet pain (minimum 6 months of conservative therapy often)
• Physical examination thoracic findings (tenderness over the facet joints, restricted range of motion)
• Imaging findings (MRI, CT, bone scan)
• facet degeneration, hypertrophy, synovitis, or instability- Failed conservative management (PT, medications, injections)
• Specific indication for intrafacet implant versus alternative procedures
• Informed consent noting Category III/emerging technology status
• Laterality (unilateral vs bilateral) and level(s) Intraoperative Documentation:
• Operative note describing the exact procedural steps
• Thoracic level(s) implanted (T4-T5, T9-T10, etc.)
• Image guidance method (fluoroscopy, CT, intraop)
• Implant type (dowel, allograft, PEEK, synthetic wedge) and manufacturer
• Implant size and position confirmed intraoperatively
• Estimated blood loss
• Number of vertebral segments treated (single vs additional, list add-on 0222T)
• Whether the implant was unilateral or bilateral (modifier 50 if bilateral) Postoperative Documentation:
• Imaging confirmation of implant position
• Pain scores and functional status
• Neurologic examination
• Wound status
• Follow-up plan (typically 2 weeks, 6 weeks, 3 months, 6 months, 1 year)

How Does CPT Code 0220T Affect Medical Billing and Reimbursement?

Reimbursement Characteristics:

Component	Detail
Category III Status	Temporary code - emerging technology
RVU Assignment	None - not assigned RVUs in the MPFS
Medicare Coverage	Typically non-covered - considered investigational under SSA 1862(a)(1)(A)
Commercial Coverage	Variable; many consider experimental/investigational
Anesthesia Code	00620 (Thoracic spine and cord, NOS)
ASC Eligible	Dependent on payer policy
Payer Considerations:

• Medicare: Category III codes are generally not covered. Medicare considers these investigational and denies payment as not reasonable and necessary. Some Local Coverage Determinations (LCDs) may provide coverage.
• Commercial Payers: Most commercial plans require prior authorization. Many consider thoracic intrafacet implants experimental/investigational and deny coverage. Check individual plan medical policies.
• Medicaid: Variable by state, most consider Category III codes as non-covered or require individual review.
• Medicare Advantage: Follows Original Medicare coverage rules - generally non-covered. Common Modifiers Used With CPT 0220T: | Modifier | Description | Use Case | |----------|-------------|----------| | 50 | Bilateral procedure | Bilateral thoracic facet implant | | 59 | Distinct procedural service | Performed with another distinct service | | 22 | Increased procedural service | Unusual complexity | | RT/LT | Right/Left | Unilateral facet implant | | GA | Waiver of liability on file | ABN obtained for non-covered service |

Understanding Base Units and Anesthesia for 0220T

Because 0220T is a Category III surgical code without RVUs, reimbursement for anesthesiology services is the key revenue component. General anesthesia for a thoracic spine procedure is reported with the anesthesia code 00620 (Anesthesia for procedures on the thoracic spine and cord; not otherwise specified). The national anesthesia base unit value for 00620 is 10 base units.

Anesthesia is reimbursed using the standard formula: (Base Units + Time Units + Qualifying Circumstance Units) x Conversion Factor = Payment

• Base Units: 10 (for 00620)
• Time Units: 1 unit per each 15 minutes of anesthesia time (most payers)
• Physical Status Modifiers (P1-P6): Required on every claim. P3 adds 1 unit, P4 adds 2, P5 adds 3 under most commercial payers.
• Qualifying Circumstances: Such codes (99100, 99116, 99135, 99140) may add units when documented.

A typical 3-hour thoracic open case at 10 base units with 12 time units (180/15) yields 22 total units before the conversion factor is applied.

What CPT or HCPCS Codes Are Commonly Billed Alongside CPT 0220T?

Associated Code/Service	Description	Billing Guidance
0222T	Additional level (add-on)	Bill for each additional facet level
00620	Anesthesia for thoracic spine	Separate bill by anesthesiologist
77002	Fluoroscopic guidance	May be included in surgical package
77011	CT guidance for spine procedure	May be separately billable
20938	Arthrodesis bone graft harvest	If autograft is used (check payer)
22867	Interspinous device	Different device - lumbar interspinous
0202T	Interspinous device placement	If performed concurrently
Important: CPT specifically prohibits reporting 0220T with fusion, instrumentation, and bone graft harvest codes at the same level, including +20930, +20931, 22600-22614, +22840, +22853, +22854, +22859. Image guidance is considered included.

What Coding Errors Should You Avoid With CPT 0220T?

Top Coding Errors Ranked by Frequency:

1. Using CPT 0220T for the Wrong Spinal Region CPT 0220T is specific to the thoracic spine. For cervical use 0219T and for lumbar use 0221T. Bill a lumbar implant as 0220T and you have an incorrect region - the claim is denied or upcoded.

2. Coding the Additional Level Incorrectly If more than one level is penetrated, do not bill 0220T twice. Use +0222T once for each additional level. Failing to use the add-on code produces an invalid claim and an overbilling risk.

3. Reporting 0220T With Fusion and Instrumentation Codes CPT guidelines prohibit reporting traditional fusion (22600-22614), instrumentation (+22840), and bone graft harvest (20931) codes at the same level. These are excluded. Including them results in unbundling edits (NCCI) denial.

4. Failing to Obtain an ABN Because Category III codes are frequently non-covered, obtain an Advance Beneficiary Notice before performing the procedure. Without it, you cannot bill the patient even when the payer denies coverage.

5. Applying Level Modifier Incorrectly The code descriptor includes “unilateral or bilateral” and single level. Do not use modifier 50 for bilateral unless your payer requires it, and do not append -22 for additional levels. The -22 modifier is for unusual complexity, not for extra levels.

6. Reporting Anesthesia Under the Wrong Code Anesthesia for the thoracic spine should be billed as 00620, not the general 01996 or a lumbar code. Verify the anesthesia provider’s or assign code matches the level.

How Does CPT Code 0220T Relate to Other CPT Codes?

0221T	Posterior intrafacet implant, lumbar	III	Same family - lumbar region
+0222T	Each additional level	III	Add-on for additional segments
22899	Unlisted spine procedure	I	Unlisted alternative if 0220T does not fit
00620	Anesthesia for thoracic spine/cord	I	Associated anesthesia code
0218T	Facet implant (older / other)	III	Related facet implant work

Real-World Coding Scenarios — How CPT 0220T Is Applied in Practice

Scenario 1: Single-Level Unilateral Thoracic Intrafacet Implant A 45-year-old female presents with chronic right mid-thoracic back pain from facet arthritis at T7-T8 refractory to 12 months of conservative management including physical therapy and two facet injections. MRI shows right T7-T8 facet hypertrophy and synovitis. She undergoes posterior right T7-T8 intrafacet implant (allograft bone dowel) under fluoroscopy. Anesthesia time 2.5 hours. Estimated blood loss 50 mL. Correct Coding (Surgeon):

• CPT 0220T - Posterior intrafacet implant (thoracic, single level), with modifier RT (right) if needed
• The procedure bundles imaging and bone graft into one code
• Anesthesia: 00620 billed separately by anesthesiologist Common Mistake: Billing a second 0220T for both T7-T8 levels when this was a single right-side implant. If there is only one thoracic level, one unit of 0220T is correct.

Scenario 2: Bilateral Single-Level Thoracic Intrafacet Implants With an Additional Level A 61-year-old female with bilateral thoracic facet syndrome at T9-T10 and an adjacent level T10-T11 undergoes bilateral posterior intrafacet implant placement at T9-T10 with an implant at T10-T11. Correct Coding (Surgeon):

• CPT 0220T-50 - Bilateral single-level intrafacet implant (thoracic)
• CPT +0222T - Additional level (T10-T11) (for the add-on level)
• Modifier 59 may apply as distinct procedural service if clinically appropriate
• Anesthesia: 00620 billed separately Common Mistake: Billing 0220T twice (once per side) instead of using modifier 50, and forgetting to bill +0222T for the extra level.

Frequently Asked Questions About CPT Code 0220T

Is CPT 0220T Covered by Medicare?

Generally no. Category III codes are considered investigational by Medicare under Section 1862(a)(1)(A) of the Social Security Act. An Advance Beneficiary Notice (ABN) should be obtained before proceeding.

Does CPT 0220T Include Imaging and Bone Graft?

Yes. The descriptor states the code “includes imaging and placement of bone graft(s) or synthetic device(s).” Do not separately report fluoroscopy or graft harvest at the same level.

What Anesthesia Code Is Used for CPT 0220T?

Anesthesia for the thoracic spine intrafacet implant is billed under CPT 00620 (Anesthesia for procedures on the thoracic spine and cord; NOS), which carries 10 base units, not under 0220T.

How Do I Code for Multiple Levels of the Implant?

Use 0220T for the first (single) level and +0222T (additional level, add-on) for each additional. The add-on code is reported in addition to the primary procedure.

Is CPT 0220T a Permanent Code?

No. Category III codes are temporary. If the procedure is established and meets Category I criteria, it may be converted to a Category I code; otherwise, it may be archived after 5 years.

What Is the Difference Between Intrafacet and Interspinous?

An intrafacet (facet wedge/dowel) implant goes into the facet joints. An interspinous device (22867) goes between the spinous processes. They address different pathologies and use different codes. 0220T is the intrafacet (facet) implant.

Key Takeaways for Billing and Coding CPT 0220T

• Code Scope: Category III code for a single-level posterior intrafacet implant in the thoracic spine
• Level-Specific: Use 0219T (cervical), 0220T (thoracic), 0221T (lumbar) based on region
• Add-On: Use +0222T for each additional level - never bill 0220T twice for levels
• Includes Imaging and Graft: The descriptor bundles image guidance and bone graft/synthetic devices
• Category III Limits: Considered investigational - obtain ABN; Medicare generally non-covered
• Anesthesia: Thoracic spine anesthesia is 00620 (10 base units), billed separately
• Documentation: Requires a documented failure of conservative management and the exact level/laterality
• Unilateral vs Bilateral: Use modifier 50 for bilateral; do not bill twice
• Payer Specific: Verify coverage and require prior authorization
• Combine Carefully: Some codes with fusion/instrumentation are excluded at the same level
