When to give 57 modifier?

Modifier 57 is appended to an Evaluation and Management (E/M) service code to indicate that the visit resulted in the initial decision to perform a major surgery.

When to Use Modifier 57

• Major Surgeries Only: The procedure must have a 90-day global surgical period.
• Timing: The E/M service must happen on the day of or the day before the major surgery.
• Initial Decision: It must be the encounter where the physician first evaluates the problem and decides that the major surgery is medically necessary.
• Placement: Append it only to the E/M code, never to the surgical procedure code itself.

When NOT to Use Modifier 57

• Minor Surgeries: Do not use it for procedures with a 0- or 10-day global period (use modifier 25 for those instead).
• Preplanned Procedures: Do not use it if the surgery was scheduled days or weeks earlier.
• Surgical Codes: Never attach it to the actual operation code.

The main difference between Modifier 25 and Modifier 57 is the global period of the procedure performed and whether the evaluation led to the choice to operate. Both are added to Evaluation and Management (E/M) codes when a doctor performs an office visit and a procedure on the same day.

Modifier 25 (Minor Procedures)

• Definition: A significant, separately identifiable E/M service by the same provider on the same day of a procedure.
• Global Period: Used for minor procedures with a 0-day or 10-day global period (such as joint injections or simple skin biopsies).
• Purpose: Shows that the exam or consultation went above and beyond the normal pre-op and post-op care tied to that minor procedure.
• Rule: Do not use if the visit only involves the routine work-up for the scheduled procedure.

Modifier 57 (Major Procedures)

• Definition: Decision for surgery.
• Global Period: Used exclusively for major procedures with a 90-day global period (such as major joint replacements or spinal surgery).
• Purpose: Appended to the E/M service that prompts the initial decision to perform the major surgery, usually done within 24 to 48 hours of the operation.
• Rule: Never use for minor procedures with 0- or 10-day global periods.

Key Comparisons

• Global Length: Modifier 25 is for 0- or 10-day periods; Modifier 57 is for 90-day major surgery periods.
• Surgical Decision: Modifier 57 specifically marks the exact visit where the major surgery choice was made, while Modifier 25 does not apply when the visit results in that major surgical decision.

Modifier 24 and Modifier 57 are both appended to Evaluation and Management (E/M) codes during a global surgical period, but Modifier 24 is for an unrelated visit during an existing postoperative period, while Modifier 57 indicates an E/M service that resulted in the initial decision to perform a major surgery.

Core Differences

Modifier 24: Unrelated Postoperative Care

• When to use: Use when the same physician performs an E/M service during a global post-op period for a problem that is completely unrelated to the initial surgery.
• Example: A patient is in the 10-day global period following a skin lesion excision and returns to the clinic with an acute sinus infection. The E/M visit for the sinus infection takes Modifier 24.
• Key rule: Routine post-op care or treatment for surgical complications cannot use Modifier 24; the issue must be a distinct, separate diagnosis or problem.

Modifier 57: Decision for Major Surgery

• When to use: Use when an E/M evaluation leads to the decision to perform a major surgery (90-day global period) either on the same day or the day before.
• Example: A patient presents to the emergency room with severe abdominal pain; the evaluation results in a diagnosis of appendicitis and an immediate choice to operate. The initial E/M code is billed with Modifier 57.
• Key rule: Do not use Modifier 57 for pre-planned or prescheduled surgeries, or for minor procedures with 0- or 10-day global periods.

You can review official guidelines via the American Academy of Professional Coders or check detailed rules through the Centers for Medicare & Medicaid Services.

No, you cannot append both modifier 25 and modifier 57 to the same evaluation and management (E/M) service code on a single claim.

Key Differences

• Modifier 25 applies to a significant, separately identifiable E/M service performed on the same day as a minor procedure (0-day or 10-day global period).
• Modifier 57 applies to an E/M service that results in the initial decision to perform a major surgery (90-day global period) within 24 hours.

Why You Cannot Use Them Together

• Mutual Exclusivity: A single E/M encounter cannot represent both a minor procedure decision/separate service and a major surgical decision at the same time.
• Global Period Rules: The global period of the procedure performed dictates which single modifier is appropriate. If you perform a major procedure, you use modifier 57. If you perform a minor procedure, you use modifier 25.
• Multiple Procedures: If a patient undergoes both a major procedure and an unrelated minor procedure on the same day, coding guidelines generally require reporting the modifier that corresponds to the major procedure (modifier 57) on the E/M service, as the decision to operate takes precedence.

Yes, modifier 24 and modifier 57 can be billed together on the same Evaluation and Management (E/M) service line when a specific clinical scenario occurs.

When to Use Modifiers 24 and 57 Together

You append both modifiers to an E/M code when a patient is in the 90-day global postoperative period of one (earlier) major surgery, and during that visit, the physician evaluates the patient and makes the initial decision to perform a second, unrelated major surgery on that same day or the day prior.

• Modifier 24: Indicates that the E/M service is unrelated to the first (earlier) surgery's global period.
• Modifier 57: Indicates that the E/M service resulted in the decision to perform the new major surgery (90-day global period).

Real-World Example

• First Event: A patient undergoes a knee replacement (major surgery with a 90-day global period) performed by Surgeon A.
• Second Event: Within that 90-day window, the patient returns to Surgeon A with severe, unrelated abdominal pain.
• The Decision: Surgeon A examines the patient, diagnoses acute appendicitis, and decides to perform an emergency appendectomy that same day.
• Billing: On the E/M service code for that office visit, the billing team appends both Modifier 24 and Modifier 57 to explain why the visit is separate from the knee surgery global period and why it led to a new major procedure.
