Orthopedic CPT Codes Cheat Sheet: 2026 Coding Guide

Orthopedic coding is more than choosing a procedure from a CPT list. A clean orthopedic claim depends on the relationship between the documented procedure, CPT code, ICD-10-CM diagnosis, laterality, modifiers, NCCI edits, global surgery rules, and payer-specific requirements.

This orthopedic CPT codes cheat sheet provides a practical 2026 reference for orthopedic providers, coders, billing teams, and practice managers. It covers common orthopedic CPT codes, E/M coding, injections, arthroscopy, fracture care, joint replacement, spine procedures, ICD-10-CM diagnosis coding, modifiers, coding scenarios, documentation requirements and selected 2026 updates.

Overview: What CPT Codes Are Used in Orthopedics?

Orthopedic practices use CPT codes across several service categories, including office E/M visits, injections and aspirations, arthroscopy, fracture treatment, joint replacement, spine surgery, nerve procedures, imaging, and other musculoskeletal services.

Five commonly encountered orthopedic CPT codes include:

CPT code	Common service
27130	Total hip arthroplasty
27447	Total knee arthroplasty
29881	Knee arthroscopy with meniscectomy
29888	Arthroscopic ACL reconstruction
29827	Arthroscopic rotator cuff repair

These are examples rather than a complete orthopedic CPT codes list. The correct code depends on the documented procedure, anatomical site, technique, and applicable CPT instructions.

What Are Orthopedic CPT Codes?

CPT or Current Procedural Terminology, is used to describe healthcare services and procedures. In orthopedics, CPT coding covers services involving the bones, joints, muscles, tendons, ligaments, nerves, and related musculoskeletal structures.

Many orthopedic surgical procedures are found in the 20000–29999 musculoskeletal surgery section, but an orthopedic claim can also contain codes from other CPT sections.

Most Common Orthopedic CPT Codes

The following table provides a practical starting point for frequently encountered orthopedic services.

CPT code	Common service	Coding focus
99202–99205	New patient office/outpatient E/M	MDM or time
99212–99215	Established patient office/outpatient E/M	MDM or time
20610	Major joint or bursa aspiration/injection without ultrasound guidance	Site, laterality, medical necessity
20605	Intermediate joint or bursa aspiration/injection without ultrasound guidance	Site and documentation
20550	Injection into a single tendon sheath, ligament, or aponeurosis	Exact structure and indication
27130	Total hip arthroplasty	Hip and procedure documentation
27447	Total knee arthroplasty	Knee, procedure, and global period
29881	Knee arthroscopy with meniscectomy	Meniscus and operative findings
29888	Arthroscopic ACL reconstruction	Reconstruction and graft documentation
29826	Arthroscopic shoulder procedure for subacromial decompression	Bundling and primary procedure relationship
29827	Arthroscopic rotator cuff repair	Tendon and operative findings
64721	Carpal tunnel release	Median nerve/carpal tunnel documentation
63030	Lumbar laminotomy with decompression of nerve root	Level and procedure
63047	Lumbar laminectomy/decompression	Level and surgical documentation
22633	Lumbar spinal fusion procedure	Approach, level, and instrumentation
22513	Vertebral augmentation procedure	Vertebral level and technique
73030	Shoulder radiographs, complete	Views and documentation
73562	Knee radiographs, 3 views	Views and laterality
73221	MRI of an upper-extremity joint	Anatomy and technical/professional reporting
73721	MRI of a lower-extremity joint	Anatomy and technical/professional reporting

Coding warning: Code descriptors and reporting instructions should be verified against the current CPT code set. A code appearing in a general orthopedic CPT list does not establish that it is separately reportable in a particular encounter.

Orthopedic CPT Codes by Procedure Category

1. Orthopedic E/M Codes

Office and outpatient E/M services are common in orthopedic practices.

New patients

99202–99205 are used for new patient office or other outpatient E/M services.

Established patients

99212–99215 are used for established patient office or other outpatient E/M services.

For current E/M reporting, code selection generally depends on medical decision-making or total time, according to the applicable E/M guidelines. The documentation should support the level reported.

Examples include:

• New evaluation of knee pain
• Follow-up for osteoarthritis
• Review of diagnostic imaging
• Surgical treatment planning
• Evaluation of a new orthopedic problem
• Postoperative evaluation when separately reportable

Do not select an E/M level simply because a note is long. The coding decision must be supported by the applicable E/M rules and documentation.

2. Orthopedic Injection and Aspiration Codes

Injection and aspiration services are common in orthopedic practices.

Examples include:

• 20605 for intermediate joint or bursa aspiration/injection without ultrasound guidance
• 20610 for major joint or bursa aspiration/injection without ultrasound guidance
• 20550 for injection into a single tendon sheath, ligament, or aponeurosis

The documentation should establish the:

• Anatomical site
• Laterality
• Clinical indication
• Procedure performed
• Medication or substance administered when applicable
• Relevant imaging or guidance when applicable
• Medical necessity

A common billing mistake

An injection does not automatically justify separately reporting an E/M service on the same date.

If an E/M service is separately reportable, the documentation must support the distinct evaluation and the applicable modifier and payer requirements.

3. Orthopedic Arthroscopy CPT Codes

Arthroscopic procedures are among the areas where orthopedic coding requires careful review of the operative report and bundling rules.

Common examples include:

CPT	Common service
29881	Knee arthroscopy with meniscectomy
29888	Arthroscopic ACL reconstruction
29826	Arthroscopic shoulder subacromial decompression
29827	Arthroscopic rotator cuff repair

The coder should verify:

• Joint
• Side
• Specific procedure
• Structures treated
• Surgical approach
• Findings
• Graft or implant details when applicable
• Whether additional procedures are separately reportable

Do not assume that every procedure documented during arthroscopy should produce a separate claim line.

CMS maintains NCCI guidance specifically addressing correct coding and procedure-to-procedure relationships. The 2026 NCCI Policy Manual includes a dedicated chapter for musculoskeletal surgery CPT codes 20000–29999.

4. Joint Replacement and Arthroplasty

Major orthopedic practices frequently report joint replacement procedures involving the hip and knee.

Common examples include:

• 27130 — total hip arthroplasty
• 27447 — total knee arthroplasty

Joint replacement claims require more than identifying the replacement procedure.

The record should support:

• Joint and laterality
• Underlying diagnosis
• Surgical indication
• Procedure performed
• Components or implants when required
• Surgical approach when relevant
• Complications when applicable
• Global surgery considerations
• Payer authorization requirements

Major orthopedic procedures may also involve extensive preoperative authorization and postoperative care workflows. These should be coordinated with coding rather than handled as isolated administrative tasks.

5. Orthopedic Fracture Coding

Fracture coding requires detailed clinical information.

Depending on the fracture and treatment, the coder may need to establish:

• Bone involved
• Anatomical location
• Laterality
• Fracture type
• Displacement
• Open or closed status when applicable
• Encounter type
• Healing status for subsequent encounters
• Manipulation
• Open or closed treatment
• Internal or external fixation

The diagnosis should not be reduced to a generic “fracture” when the medical record provides more specific information.

For ICD-10-CM, the official guidelines emphasize the importance of complete documentation and review of the entire record to determine the reason for the encounter and conditions treated.

6. Spine CPT Coding

Spine coding deserves separate attention because procedures may involve multiple levels, decompression, fusion, instrumentation, grafting, and other components.

Common spine coding categories include:

• Lumbar decompression
• Laminectomy
• Laminotomy
• Discectomy
• Spinal fusion
• Instrumentation
• Bone grafting
• Vertebral augmentation
• Other spinal procedures

Examples of commonly encountered codes include:

• 63030 — lumbar laminotomy/decompression of nerve root
• 63047 — lumbar laminectomy/decompression
• 22633 — lumbar spinal fusion
• 22513 — vertebral augmentation, thoracic

Why older spine cheat sheets can be misleading

A search for “spine coding cheat sheet 2023” may return older resources, but coding rules are not static.

CPT is updated annually, while Medicare NCCI edits and other payer requirements can also change. CMS’s 2026 NCCI materials are effective beginning January 1, 2026, and CMS publishes subsequent quarterly updates.

Always verify the code set and payer policy applicable to the actual date of service.

Orthopedic ICD-10-CM Coding

CPT answers:

What service was performed?

ICD-10-CM answers:

Why was the patient treated?

A strong orthopedic coding workflow therefore connects the procedure to the diagnosis that supports the encounter and medical necessity.

What Are the Most Common ICD-10 Codes Used in Orthopedics?

There is no single universal list of “most common” orthopedic ICD-10-CM codes across every orthopedic practice. Code frequency varies according to the practice’s specialty, patient population, procedures, and referral mix.

Common diagnosis categories include:

• Knee osteoarthritis
• Hip osteoarthritis
• Shoulder disorders
• Meniscal injuries
• Ligament injuries
• Fractures
• Tendon disorders
• Carpal tunnel syndrome
• Spine disorders

For 2026, use the applicable ICD-10-CM release for the date of service. CDC/NCHS identifies the April 1, 2026 FY26 release as applicable for services from April 1 through September 30, 2026, with the FY27 release beginning October 1, 2026.

Orthopedic Coding Guidelines: 7 Rules to Check Before Submission

1. Code From the Documentation

The operative note, procedure note, and clinical record should support the reported service.

Do not code from assumptions.

2. Confirm Anatomical Site and Laterality

Orthopedic claims frequently involve paired structures.

Verify:

• Right
• Left
• Bilateral
• Specific joint
• Specific bone
• Specific anatomical structure

3. Match CPT and ICD-10-CM

The diagnosis should support the procedure and medical necessity.

The 2026 ICD-10-CM Official Guidelines emphasize complete and accurate documentation and state that the entire record should be reviewed to determine the reason for the encounter and conditions treated.

4. Check NCCI Edits

Before reporting multiple procedures on the same date, review applicable NCCI procedure-to-procedure edits.

CMS updates NCCI edit files during the year, so an old coding spreadsheet may not reflect the current edit configuration. CMS issued a 2026 quarterly NCCI update effective July 1, 2026.

5. Validate Modifiers

A modifier should explain a legitimate coding circumstance.

Do not append a modifier merely because a claim would otherwise deny.

CMS specifically states that modifiers should not be used solely to bypass an NCCI edit when the clinical circumstances do not support the modifier.

6. Review the Global Period

Orthopedic surgery frequently involves procedures with global surgical periods.

CMS uses global surgery indicators including:

• 000 — day-of-procedure global concept
• 010 — 10-day postoperative period
• 090 — 90-day postoperative period

CMS explains that a 090 global includes a one-day preoperative period and 90-day postoperative period in the Medicare fee schedule payment.

7. Verify Payer Requirements

Medicare, Medicaid, and commercial payers can have different coverage, authorization, documentation, modifier, and claim-submission requirements.

A CPT code being valid does not automatically mean the payer will reimburse it under every circumstance.

Orthopedic Modifiers Every Billing Team Should Understand

Modifier 25: Significant, Separately Identifiable E/M

Modifier 25 may be appropriate when a significant, separately identifiable E/M service is performed on the same day as another procedure.

The documentation must support the additional E/M work.

Do not use Modifier 25 simply because an office visit and procedure appear on the same claim.

Modifier 50: Bilateral Procedure

Modifier 50 may identify a bilateral procedure when the applicable coding and payer instructions permit that reporting method.

Always check payer-specific requirements because bilateral reporting can vary.

RT and LT: Laterality

RT and LT identify right and left sides when applicable.

These are especially important in orthopedic billing because the same procedure may be performed on either side of the body.

Modifier 57: Decision for Major Surgery

Modifier 57 may apply when the E/M service results in the decision to perform major surgery, subject to the applicable global surgery rules and documentation.

Modifier 59: Distinct Procedural Service

Modifier 59 is one of the most misunderstood modifiers in orthopedic billing.

It should not simply mean:

“I performed two procedures, so I need Modifier 59.”

CMS explains that NCCI-associated modifiers must be supported by the clinical circumstances. Appropriate circumstances can include separate encounters, separate anatomical sites, or other qualifying circumstances.

CMS also provides the more specific modifiers:

• XE — separate encounter
• XS — separate structure
• XP — separate practitioner
• XU — unusual non-overlapping service

When appropriate, a more specific modifier may be preferable to Modifier 59. CMS published updated 2026 guidance specifically addressing 59, XE, XP, XS, and XU.

Modifiers 54 and 55

These modifiers can be relevant when surgical care and postoperative management are divided between practitioners.

CMS’s global surgery guidance addresses transfer-of-care situations and the reporting of surgical and postoperative portions of global packages.

Modifier 78

Modifier 78 may apply when a related procedure requires an unplanned return to the operating/procedure room during the postoperative period.

CMS’s 2026 NCCI manual discusses return-to-operating-room situations, including certain postoperative complications that require treatment in the operating room.

Modifier 79

Modifier 79 may apply when an unrelated procedure is performed during a postoperative global period, provided the applicable requirements are met.

Orthopedic Surgery Coding Scenarios

Real-world cases help illustrate how documentation, CPT codes, modifiers, NCCI edits, and payer rules work together.

• Knee Evaluation + Injection: Confirm whether the E/M service is separately identifiable and whether Modifier 25 is supported. An evaluation before an injection is not automatically separately billable.
• Arthroscopy + Multiple Procedures: Identify each documented procedure, review CPT and NCCI rules, and report additional codes only when separately supported.
• Bilateral Procedure: Verify whether Modifier 50 or RT/LT reporting applies and follow the payer’s billing requirements.
• Postoperative Visit: Check the global surgery period before billing a separate E/M service. Routine postoperative care may be included in the global package.
• Return to OR: Review the original procedure, global period, documentation, and whether Modifier 78 is appropriate for an unplanned return to the operating room.

2026 Orthopedic CPT Coding Updates

The 2026 CPT code set includes 418 changes, with several updates relevant to orthopedic and musculoskeletal procedures.

Two notable new orthopedic codes are:

• CPT 27458: Femoral osteotomy with insertion of an externally controlled intramedullary lengthening device.
• CPT 27713: Tibial osteotomy, including fibula when applicable, with insertion of an externally controlled intramedullary lengthening device.

For orthopedic practices, these updates make it important to review EHR code lists, charge masters, authorization rules, claim edits, and payer policies regularly. Keeping coding workflows current can help prevent avoidable claim errors and denials.

2026 NCCI and Orthopedic Coding

NCCI is particularly important in orthopedic surgery, where multiple procedures may be performed during the same operative session. CMS’s 2026 NCCI Policy Manual includes specific guidance for musculoskeletal surgery.

Before claim submission, coders should review procedure-to-procedure edits, modifier rules, add-on codes, anatomical distinctions, separate procedures, and global surgery relationships. CMS also updated its NCCI edit files during 2026, making regular review important for accurate orthopedic coding and billing.

Orthopedic Global Surgery Coding

Global surgery is particularly important for orthopedic practices because many major orthopedic procedures carry 90-day global periods.

CMS explains that:

• 000 indicates a day-of-procedure global concept.
• 010 represents a 10-day postoperative period.
• 090 represents a major surgical procedure with a 90-day postoperative period.

The global package can affect whether postoperative E/M services are separately payable.

CMS also continues to examine global surgery payment accuracy. For CY 2026, CMS solicited comments on how global surgical service valuation and transfer-of-care modifiers should be evaluated for 90-day packages.

That makes global-period review an important part of orthopedic revenue-cycle management.
