In the complex world of medical billing, modifiers play a critical role in ensuring accurate claim submission and reimbursement. Among these, Surgical Modifier 62 stands out as one of the most important for surgeries involving more than one primary surgeon. Understanding how and when to apply this modifier can make the difference between a clean claim and a costly denial. This guide from Allzone Management Services breaks down everything you need to know about Modifier 62 — its definition, use cases, documentation requirements, and billing guidelines.
What Is Surgical Modifier 62?
CPT Modifier 62 is used when two surgeons work together as primary surgeons during a single operative session. Each surgeon performs distinct parts of the same procedure, and both must actively participate in the surgery. Unlike assistant surgeon modifiers (such as 80, 81, or 82), Modifier 62 identifies co-surgeons, not assistants.
For example, in complex surgeries like cardiovascular, orthopedic, or neurosurgical procedures, two surgeons may collaborate, each bringing specialized expertise. The use of Modifier 62 ensures that both ...
... are properly recognized and reimbursed for their efforts.
When to Use Modifier 62
Modifier 62 should be reported only when:
The surgical procedure is extensive or complex enough to require two primary surgeons.

Both surgeons operate on distinct parts of the same surgical procedure.

Each surgeon dictates an individual operative report describing their contribution.

The CPT code description does not already include “two surgeons” or “team surgery.”

It’s essential that the operative documentation clearly supports the necessity of two primary surgeons to ensure payer acceptance and prevent claim denials.
Documentation Requirements for Modifier 62
Documentation plays a crucial role in Modifier 62 billing. Each surgeon must provide:
A separate operative note outlining the specific portion of the procedure they performed.

A statement explaining why the procedure required two surgeons.

Clear indication of collaboration and shared responsibility in the procedure.

Failure to include these details often leads to denials or payment reductions, especially under strict payer policies such as Medicare or commercial insurance plans.
At Allzone Management Services, our billing experts ensure all required documentation and supporting details are in place before claims are submitted — minimizing errors and maximizing reimbursement.
Common Coding Scenarios for Modifier 62
Let’s consider a few examples to illustrate when Modifier 62 applies:
Example 1: Two orthopedic surgeons perform a complex spinal fusion. Each handles a distinct portion of the spine. Both report the same CPT code with Modifier 62.

Example 2: A general surgeon and a vascular surgeon collaborate during a major abdominal procedure. Since both are primary surgeons, each bills the same CPT code appended with Modifier 62.

However, if one surgeon assists the other, Modifier 80 or 82 would be more appropriate instead of 62.
Billing Guidelines for Modifier 62
Here are the key rules to follow when billing Surgical Modifier 62:
Use the same CPT code for both surgeons.

Append Modifier 62 to the CPT code for each surgeon’s claim.

Ensure both operative reports support co-surgery.

Reimbursement is typically split between the surgeons — often 62.5% of the fee schedule per surgeon, though this may vary by payer.

Not all procedures are eligible for Modifier 62 — always verify with payer guidelines or CPT Assistant references.

The Allzone billing team emphasizes payer-specific rules, ensuring compliance while optimizing reimbursement for co-surgeon procedures.
Why Modifier 62 Is Often Misused
Despite being straightforward in theory, Modifier 62 is often misapplied due to misunderstanding between “co-surgeon” and “assistant surgeon” roles. Common errors include:
Using Modifier 62 when only one surgeon is performing the majority of the procedure.

Reporting Modifier 62 for team surgeries involving more than two surgeons (requires Modifier 66 instead).

Missing documentation of distinct portions performed by each surgeon.

These mistakes can lead to claim denials, audits, or compliance risks. Partnering with an experienced medical billing company like Allzone ensures accurate code selection and compliant billing practices.
