Which CPT Codes Cover Orthopedic Consultations
Orthopedic consultations in the outpatient setting are billed using CPT codes 99242 through 99245. These are the four active office and outpatient consultation codes recognized by most private payers. Each level corresponds to a different degree of medical decision-making complexity and total physician time. Code 99241 was deleted in 2023 and is no longer active.
For inpatient orthopedic consultations, the applicable codes are 99252 through 99255. These cover evaluations performed when the patient is admitted to a hospital or other inpatient facility and the consulting orthopedic specialist is called in by the admitting physician.
There is one critical exception that affects a significant portion of orthopedic practices: Medicare stopped recognizing consultation codes in 2010. If your patient is covered by Medicare, you cannot bill 99242 through 99245. Instead, you bill a standard office visit code for new patients (99202 through 99205) or established patients (99212 through 99215), depending on the complexity of the encounter.
Why Consultation Codes Are Different from Regular Office Visit Codes
A consultation code is not simply a synonym for a specialist visit. It has a specific meaning in the CPT system, and billing it incorrectly is one of the more common sources of denial and audit risk in orthopedic practices.
For a service to qualify as a consultation under CPT, three requirements must be met. These are sometimes called the three Rs: request, render, and report. First, there must be a documented request from another physician or qualified healthcare professional asking for the orthopedic specialist’s opinion on the patient’s condition. Second, the consultant must render the evaluation and form an opinion. Third, a written report of that opinion must be sent back to the requesting provider.
If any one of these three elements is absent from the documentation, the service is not a consultation under CPT. It is a regular office visit, and it should be coded as one. Billing a consultation code for a service that does not meet all three requirements is considered upcoding and creates compliance risk.
The Four Levels of Outpatient Orthopedic Consultation Codes
CPT 99242: Straightforward Medical Decision-Making
This code applies when the consultation involves straightforward medical decision-making or typically requires approximately 20 minutes of total physician time. In orthopedics, this level is appropriate for patients presenting with a single, well-defined problem of low complexity where the management options are limited and the data reviewed is minimal.
An example would be a consultation for a patient referred for evaluation of a stable, acute wrist sprain with a straightforward treatment path. The documentation must support the straightforward MDM designation or time-based selection.
CPT 99243: Low Complexity Medical Decision-Making
This code reflects low complexity medical decision-making or approximately 30 minutes of total physician time. It is appropriate for patients with a problem of low to moderate severity, where there are a limited number of diagnoses to consider and the management options involve minimal risk.
An example in orthopedics might be a new patient consultation for mild knee osteoarthritis with a straightforward conservative management plan. The visit involves reviewing imaging and forming a recommendation, but the clinical picture is relatively clear.
CPT 99244: Moderate Complexity Medical Decision-Making
This is the most commonly used consultation code in orthopedics. It applies when the encounter involves moderate complexity medical decision-making or approximately 40 minutes of total physician time. Moderate complexity situations involve multiple problems or conditions, more data to review and analyze, and management options that carry some risk.
A patient referred for evaluation of persistent shoulder pain with a history of prior procedures, imaging to review, and a decision between conservative management, injection therapy, or surgical planning is a typical 99244 scenario. The documentation needs to reflect the complexity of the data reviewed and the decision-making involved.
CPT 99245: High Complexity Medical Decision-Making
This code represents the highest level of outpatient consultation. It applies to encounters involving high complexity medical decision-making or approximately 55 minutes of total physician time. High complexity situations typically involve severe or multiple conditions, extensive data review, and management decisions that carry significant risk.
A complex spine consultation for a patient with multi-level pathology, prior surgical history, multiple comorbidities, and a decision about surgical intervention is the type of encounter that supports a 99245. The documentation must be thorough enough to demonstrate the high complexity of the clinical decision made.
| CPT Code | MDM Level | Time (Approx) | Typical Orthopedic Scenario |
| 99242 | Straightforward | 20 minutes | Acute, single-problem evaluation with clear path |
| 99243 | Low complexity | 30 minutes | Mild condition, limited options, minimal risk |
| 99244 | Moderate complexity | 40 minutes | Multiple considerations, imaging review, some risk |
| 99245 | High complexity | 55 minutes | Complex pathology, multiple comorbidities, high risk |
Inpatient Orthopedic Consultation Codes: 99252 Through 99255
When an orthopedic specialist is called to consult on a hospitalized patient, the inpatient consultation codes apply. These follow the same three-R documentation requirements as outpatient codes: request, render, report.
Code 99252 is the lowest active inpatient consultation level, reflecting straightforward MDM. Code 99253 represents low complexity, 99254 moderate complexity, and 99255 high complexity. Code 99251 was deleted in 2023. The same Medicare exclusion applies: Medicare does not recognize these codes and requires the use of initial hospital care codes 99221 through 99223 instead.

The Medicare Exception: What to Bill When Consultation Codes Do Not Apply
This point causes significant confusion in orthopedic practices. CMS eliminated consultation codes for Medicare patients in 2010, and that policy has not changed. If you bill 99242 through 99245 for a Medicare beneficiary, the claim will be denied.
For Medicare patients, the visit is billed as an office visit using the standard E/M codes. New patients use 99202 through 99205. Established patients use 99212 through 99215. The level is determined by the same MDM or time-based criteria that apply to consultation codes. The clinical complexity of the encounter drives the code level, but the code family is different.
The practical implication is that orthopedic practices need to know each patient’s payer before selecting the billing code for a consultation visit. Most private payers still recognize 99242 through 99245. Medicare does not. Applying the wrong code family is a denial waiting to happen.
Essential Orthopedic Procedure CPT Codes Beyond Consultations
Consultation codes cover the evaluation. Orthopedic billing also requires accurate coding for the procedures that follow. Here are the most frequently used procedure code categories in orthopedic practice.
Evaluation and Management for Follow-Up Visits
After the initial consultation, follow-up visits for established orthopedic patients use codes 99212 through 99215. Post-operative visits within the global period are included in the surgical package and are not billed separately for 90-day global procedures.
Major Joint Surgeries
Total knee arthroplasty is reported with CPT 27447. Total hip arthroplasty uses 27130. Total shoulder arthroplasty uses 23472. These carry 90-day global periods, meaning routine follow-up care within 90 days of surgery is bundled into the surgical fee and cannot be billed separately.
Arthroscopic Procedures
Arthroscopic knee meniscectomy is billed under 29881, specifying the compartment and laterality. Arthroscopic shoulder rotator cuff repair uses 29827. Hip arthroscopy for labral repair is coded as 29862. Laterality modifiers RT and LT are required when procedures are performed on one side.
Injection and Aspiration Codes
Large joint injection or aspiration such as the knee or shoulder uses 20610. Intermediate joints like the elbow or ankle use 20605. Small joints including fingers use 20600. All injection claims require documentation of medical necessity, the medication injected, laterality, and the anatomical site.
Fracture Care Codes
Fracture coding in orthopedics depends on the treatment approach, not the fracture type alone. Closed treatment of a distal radius fracture without manipulation uses 25600. With manipulation, it is 25605. Open reduction internal fixation uses 25607. Each carries its own global period and documentation requirements.
Documentation Requirements That Directly Affect Reimbursement
Since the 2021 E/M guideline changes, consultation code selection for the 99242 through 99245 range is based on either medical decision-making or total physician time. You choose whichever best supports the level of service provided. Choosing time requires documenting the total time spent on the date of service including all activities related to the visit. Choosing MDM requires documentation that reflects the complexity of problems addressed, the data reviewed, and the risk of the management decisions made.
For orthopedic consultations specifically, the documentation should also include the written referral or request from the sending provider, the clinical question being addressed, the specialist’s findings and assessment, and the written report back to the requesting provider. Without all of these elements, the service does not meet the definition of a consultation under CPT.
Common Billing Mistakes in Orthopedic Consultation Coding
- Billing consultation codes for Medicare patients instead of standard office visit codes
- Missing the written referral or request in the documentation, which disqualifies the service as a consultation
- Failing to send a written opinion back to the requesting provider
- Using modifier 25 incorrectly when billing an E/M service on the same day as a procedure
- Billing post-operative follow-up visits separately during the global period
- Applying the wrong laterality modifier or omitting it entirely on bilateral or single-side procedures
- Bundling errors on arthroscopic procedures where component services are incorrectly separated or incorrectly combined
Frequently Asked Questions About CPT Codes for Orthopedic Consultations
Can I Bill a Consultation Code for A Medicare Patient?
No. Medicare eliminated consultation codes in 2010. For Medicare beneficiaries, orthopedic consultation services are billed as standard new patient or established patient office visits using codes 99202 through 99215, depending on whether the patient is new or established and the complexity of the visit.
What Three Elements Must Be Documented to Support a Consultation Code?
The three required elements are a documented request from another physician, the rendering of the evaluation and formation of an opinion, and a written report sent back to the requesting provider. These are sometimes called the three Rs: request, render, and report. All three must be present in the documentation.
What Is the Most Commonly Used Consultation Code in Orthopedics?
CPT 99244, which reflects moderate complexity medical decision-making or approximately 40 minutes of physician time, is the most commonly used outpatient consultation code in orthopedic practice. It fits the clinical profile of most new specialty referrals involving imaging review, multiple management options, and some degree of treatment risk.
What Happens If I Use the Wrong Consultation Code Level?
Using a higher-level code than the documentation supports is considered upcoding and creates compliance risk. Payers conduct audits based on coding patterns, and consistently billing 99245 when 99244 or 99243 is more appropriate will eventually attract review. Undercoding, while less visible, results in lost revenue.
Are Post-Operative Visits Billed Separately from The Surgical Code?
No. For procedures with a 90-day global period, all routine post-operative follow-up care within that 90-day window is bundled into the surgical fee. Billing these visits separately results in a denial. If a patient presents during the global period for an unrelated condition or a complication that requires significant additional work, modifier 24 or 79 may apply, but these require careful documentation.
What Modifiers Are Most Important in Orthopedic Billing?
The most frequently used modifiers in orthopedic billing include RT and LT for laterality on single-side procedures, 50 for bilateral procedures, 59 to indicate a distinct procedural service, 25 for a significant and separately identifiable E/M service on the same day as a procedure, and 24 for an unrelated E/M service during a post-operative period.
How Do I Handle Billing When the Orthopedic Consultation Leads Directly to Surgery?
If the consultation and the decision to perform surgery occur during the same encounter, the consultation is separately billable as long as it meets the three-R documentation requirements and the surgeon documents the distinct consultation work. If the decision to operate was made by the referring physician before the visit and the specialist is simply scheduling the procedure, the encounter may not qualify as a full consultation.
