Orthopedic billing in Athenahealth becomes difficult when one patient encounter touches several layers of coding: a surgical procedure, postoperative visits, staged procedures, unrelated E/M services, and NCCI bundling rules. The problem is not simply entering the right CPT code. Your billing team has to determine what is already included in the surgical payment, what can be reported separately, and what documentation supports the modifier on the claim.
That raises an important question: How does an orthopedic practice keep global surgical days, modifiers, and procedure-to-procedure edits from becoming separate revenue-cycle problems?
The answer is a specialty-specific workflow. By combining accurate surgical-date tracking, documentation review, modifier validation, NCCI checks, and disciplined claim follow-up within the practice’s Athenahealth environment, orthopedic teams can identify coding issues before they become avoidable denials.
Why Orthopedic Billing Requires a Specialized Workflow
Orthopedic practices manage a combination of office visits, injections, imaging, fracture care, durable medical equipment, and surgical procedures, which makes orthopedic billing services particularly dependent on specialty-specific coding and claim workflows.
CMS identifies 000-, 010-, and 090-day global indicators for services subject to different postoperative payment rules. A 090 indicator represents major surgery with a one-day preoperative period and a 90-day postoperative period included in the Medicare fee schedule payment.
That means the billing team cannot evaluate an orthopedic encounter in isolation.
A postoperative E/M visit may be included in the original surgical payment. Another procedure may require a modifier because it is staged or unrelated. A separate procedure may also trigger an NCCI edit because the code combination is not normally reportable together.
For orthopedic billing in Athenahealth, the workflow should connect these pieces rather than treating coding, claim scrubbing, and follow-up as separate tasks.
How to Build Surgical Global Service Days Tracking Into the Workflow
The first control is knowing which patient is inside a surgical global period before the next claim is released.
CMS explains that Medicare payment for many surgical procedures includes postoperative visits occurring during a 10- or 90-day global period. A practical orthopedic workflow should therefore capture:
- Date of the original surgical procedure
- CPT code and applicable global indicator
- Expected end of the postoperative period
- Subsequent encounters during that period
- Whether the encounter relates to the original surgery
- Whether another procedure occurred
- Documentation supporting any applicable modifier
- Whether the payer follows Medicare rules or has different requirements
Athenahealth states that athenaOne supports charge capture, claim scrubbing, and claim alarms within its billing and practice-management workflows. An orthopedic practice can use those capabilities as part of a broader internal control process, while maintaining human review for coding decisions that depend on the clinical record.
Why the surgical date matters
The surgical date establishes the reference point for determining whether a later service falls within the applicable global period.
Instead of asking a biller to remember whether a patient had surgery several weeks earlier, the workflow should surface the relevant surgical history during charge review. A simple internal control can follow this sequence:
Surgery performed → global period identified → subsequent encounter flagged → clinical relationship reviewed → modifier evaluated → claim scrubbed → claim released
This is more reliable than trying to correct global-period mistakes after a payer denial.
Modifier 24 and 58 Usage in an EHR Workflow
Modifiers 24 and 58 are not interchangeable. They address different circumstances, and the distinction should be built into the billing team’s review process.
Modifier 24: Unrelated E/M During a Postoperative Period
Modifier 24 identifies an E/M service furnished during a postoperative period that is unrelated to the original surgery.
CMS specifically states that postoperative E/M services related to recovery from surgery are included in the global surgical package. It also explains that an unrelated postoperative E/M service may be reported with modifier 24 when the documentation supports that the service is unrelated to the surgical procedure.
For example, consider a patient recovering from orthopedic surgery who returns during the postoperative period for evaluation of an unrelated medical problem. The billing team should not automatically apply modifier 24 simply because a different diagnosis appears on the claim. The record needs to support the distinction.
A useful review question is:
Is this visit addressing the surgical episode, or is it addressing a genuinely unrelated problem?
If the documentation does not support the answer, the claim should be reviewed before submission.
Modifier 58: Staged or Related Procedure
Modifier 58 serves a different purpose. CMS describes modifier 58 as applying to a staged or related procedure or service performed by the same provider during the postoperative period. The service may have been planned prospectively, may be more extensive than the original procedure, or may represent therapy following a diagnostic surgical procedure. CMS also states that reporting modifier 58 starts a new postoperative period for the subsequent procedure.
That makes modifier 58 particularly important for orthopedic surgical workflows involving planned subsequent procedures. The biller should therefore establish:
- What was the original procedure?
- What is the subsequent procedure?
- Was the subsequent service planned or expected as part of the treatment sequence?
- Does the documentation support the relationship?
- Does the payer apply Medicare’s rule or a different commercial policy?
Modifier 24 vs. 58: A Practical Comparison
| Modifier | General purpose | Billing-team question |
| 24 | Unrelated E/M during a postoperative period | Is the E/M service genuinely unrelated to the original surgery? |
| 58 | Staged or related procedure during the postoperative period | Was the subsequent procedure planned, staged, more extensive, or therapeutic following a diagnostic procedure? |
| 78 | Related procedure requiring a return to the operating/procedure room during the postoperative period | Is this a related return to the OR rather than a planned staged procedure? |
| 79 | Unrelated procedure during the postoperative period | Is the procedure unrelated to the original surgery? |
CMS separately identifies modifier 78 for an unplanned return to the operating or procedure room for a related procedure during the postoperative period, while modifier 58 addresses staged or related procedures.
Avoiding Unbundling Errors in Orthopedic Surgery
Global-period mistakes are only one part of orthopedic surgical billing. Procedure-to-procedure edits can create another problem when the billing team reports code combinations that are not separately payable.
CMS’s NCCI program is specifically designed to prevent inappropriate payment when certain CPT or HCPCS code combinations should not be reported together. For PTP edits, CMS identifies a Column One and Column Two code; the Column Two service is generally denied unless the edit allows an appropriate modifier and the clinical circumstances support its use.
This is why an orthopedic claim should not be evaluated solely by asking whether each individual code is correct. The more important question is:
Are these services separately reportable together under the applicable coding rules?
Common workflow points for preventing unbundling
Before releasing an orthopedic surgical claim, review:
- Code combinations subject to current NCCI PTP edits
- Whether the secondary service is inherently included
- Whether the documentation supports a separately reportable service
- Whether a modifier is permitted for the applicable edit
- Whether the payer follows Medicare NCCI or has its own commercial editing rules
- Whether the operative note supports the services reported
CMS updates its NCCI PTP files quarterly. The current 2026 Quarter 4 practitioner files became effective October 1, 2026, demonstrating why a static list of code combinations should not be treated as permanently current.
How Dedicated Orthopedic Billers Strengthen the Workflow
A general billing process can process orthopedic claims, but orthopedic practices benefit from staff who understand the relationships between surgical coding, global periods, documentation, and payer edits. A specialized orthopedics billing workflow should assign clear responsibility for:
1. Surgical charge review
The team verifies that the procedure documented by the surgeon corresponds with the billed service and that relevant anatomical and procedural details are captured.
2. Global-period review
The team checks whether the patient remains within an applicable postoperative period before separately reporting subsequent E/M services or procedures.
3. Modifier validation
Modifiers are evaluated according to the actual circumstances documented in the medical record.
4. NCCI review
Current NCCI edits are checked where applicable rather than relying on an outdated internal cheat sheet.
5. Claim-quality review
Claims are reviewed for coding, documentation, payer, and submission issues before transmission.
6. Denial feedback
When a payer rejects or denies a claim, the reason should feed back into the workflow. If the same modifier or procedure combination repeatedly generates denials, the practice should determine whether the problem is coding, documentation, payer policy, or workflow configuration.
Athenahealth states that its billing platform includes automated claim scrubbing and claim alarms designed to help identify downstream claim issues. Those tools can support the process, but they do not eliminate the need for qualified coding review when the correct billing treatment depends on clinical circumstances.
A Practical Orthopedic Billing Workflow in Athenahealth
A reliable process can be organized into six stages:
Stage 1: Capture the surgical event
Record the surgical date, procedure, provider, and payer information accurately.
Stage 2: Identify the applicable global period
Determine whether the procedure carries a 0-, 10-, or 90-day Medicare global indicator, or whether the relevant commercial payer uses different rules.
Stage 3: Flag subsequent services
When another encounter occurs during the applicable period, review it before treating the service as separately billable.
Stage 4: Match the service to the correct billing rule
Determine whether the service is:
- Included in the global package
- An unrelated E/M service
- A staged or related procedure
- A related return to the operating room
- An unrelated procedure
- A service affected by an NCCI edit
Stage 5: Validate documentation and modifiers
The modifier should reflect the documented circumstances. Do not use a modifier simply because it appears to be the fastest way around a denial edit.
Stage 6: Scrub and release the claim
Use the practice’s available Athenahealth claim-scrubbing and workflow controls, then perform any specialty-specific review required before submission. Practices that need additional support with these processes can use Athenahealth billing services to help manage claim processing, payment posting, and denial-related workflows.
What Orthopedic Practices Should Audit Monthly
A monthly audit can reveal whether the workflow is actually preventing revenue leakage. Track:
| Audit area | What to review |
| Global-period claims | E/M and procedures submitted during open global periods |
| Modifier 24 | Whether documentation supports unrelated status |
| Modifier 58 | Whether staged/related procedures meet the applicable criteria |
| Modifier 78/79 | Whether return-to-OR and unrelated procedures are classified correctly |
| NCCI edits | Repeated PTP edit failures |
| Denials | Modifier, bundling, documentation, and payer-policy trends |
| Unbilled services | Services potentially missed because staff assumed they were included |
| Claim corrections | Frequency and reason for corrected claims |
The objective is not simply to lower the number of denials. A better question is whether the practice is identifying both sides of the problem: services that should not have been billed separately and legitimate services that were never captured correctly.
Orthopedic Practice Revenue Cycle Solutions Should Go Beyond Claim Submission
Orthopedic revenue cycle management should connect coding accuracy with operational controls. For practices using Athenahealth, that can include:
- Specialty-specific charge review
- Surgical global-period monitoring
- Modifier review
- NCCI edit monitoring
- Denial trend analysis
- Documentation feedback
- Corrected-claim management
- A/R follow-up
- Regular billing audits
This broader approach is especially useful when the same orthopedic practice handles multiple surgeons, subspecialties, facilities, and payers.
The Bottom Line
Orthopedic billing in Athenahealth requires more than accurate code entry. The billing team has to connect the surgical date, global-period rules, documentation, modifier selection, NCCI edits, and payer requirements before the claim leaves the practice.
Modifier 24 should be reserved for appropriately documented unrelated E/M services during a postoperative period, while modifier 58 addresses qualifying staged or related procedures. CMS also maintains current NCCI edit files and updates them quarterly, so orthopedic billing teams should not rely on outdated bundling rules.
The most effective workflow is therefore one that combines Athenahealth’s billing capabilities with specialty-specific human review. That gives orthopedic practices a repeatable process for identifying global-period issues, preventing avoidable unbundling, and improving claim accuracy before problems reach the denial queue.
FAQs
How does global-period tracking affect orthopedic billing?
Global-period tracking helps the billing team identify services that occur during the postoperative period before deciding whether they can be reported separately. Medicare uses 0-, 10-, and 90-day global indicators for applicable surgical services.
When is modifier 24 used in orthopedic billing?
Modifier 24 is used for an appropriately documented E/M service during a postoperative period when the service is unrelated to the surgery. CMS states that documentation must support the unrelated nature of the service.
When should modifier 58 be used?
Modifier 58 is used for qualifying staged or related procedures during a postoperative period. CMS identifies prospective planning, a more extensive subsequent procedure, and therapy following a diagnostic surgical procedure among the circumstances associated with modifier 58.
Does every orthopedic surgery have a 90-day global period?
No. Medicare uses different global indicators. CMS identifies 000, 010, and 090 indicators, corresponding to different payment and postoperative-period rules. The applicable code and payer policy should be checked before billing.
How can orthopedic practices reduce unbundling errors?
Use current NCCI PTP edits, review code combinations before submission, confirm whether a service is separately reportable, and verify that any modifier used is supported by the documentation and applicable coding rules. CMS updates NCCI files quarterly.
Can Athenahealth automatically determine every orthopedic modifier?
The billing platform can support automated claim workflows, charge capture, claim scrubbing, and claim alarms, but modifier decisions can depend on clinical circumstances and documentation. Those decisions should still receive appropriate coding review.
