Destination Modifiers
A list of the most frequently used CPT (Current Procedural Terminology) modifiers,
HCPCS (Healthcare Common Procedure Coding System) modifiers has been compiled for your
reference.
Modifiers provide the means by which the reporting provider can indicate a service or
procedure has been altered by some specific circumstance but has not changed in its
definition or code.
Modifiers may be used to indicate that:
- A service or procedure has both a professional and technical component
- A service or procedure was performed by more than one physician
- A service or procedure has been increased or reduced
- Only part of a service was performed
- An additional service was performed
- A bilateral procedure was performed more than once
- Unusual events occurred
CPT MODIFIERS (Used in
Medicare Part B)
| 22 |
Unusual procedural service - Surgeries for which services performed are significantly greater than usually required, may be billed with the 22 modifier added to the CPT code. Include a concise statement about how the service differs from the usual. |
| 23 |
Unusual Anesthesia. |
| 24 |
Unrelated Evaluation & Management service by the same physician during a
postoperative period. |
| 25 |
Significant, separately identifiable E&M service by the same physician on the same
day of the procedure or other therapeutic service which has (0-10 day global period). A
separate diagnosis is not needed. This modifier is used on the E &M service |
| 26 |
Professional Component – Certain procedures are a combination of a physician
component may be identified by adding the modifier 26 to the usual procedure number. All
diagnostic testing with a technical and professional component done in an outpatient or
inpatient setting must reflect the 26 modifier. The fiscal intermediary (Part A Medicare)
will reimburse the facility for the technical component. |
| 50 |
Bilateral procedure – Bilateral services are procedures performed on both sides
of the body during the same operative session or on the same day. Medicare will approve
150 percent of the fee schedule amount for those services. |
| 51 |
Multiple Procedures – Internal use only by Carrier. |
| 52 |
Reduced Services - Use modifier 52 (reduced service) to indicate a service or procedure is partially reduced or eliminated at the physician's election. If claims are submitted electronically with Modifier 52, we will request medical records from the provider before we can process the claims. If claims are submitted on paper for Modifier 52, we expect that medical records will accompany the claim; without this information, your claim may be denied. Include office records, test results, operative notes, or hospital records to substantiate the reason for reporting a reduced service. |
| 53 |
Discontinued Procedure - Under certain circumstances, the physician may elect to terminate a surgical or diagnostic procedure. Due to extenuating circumstances, or those that threaten the well being of thepatient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. If claims are submitted electronically with Modifier 53, we will request medical records from the provider before we can process the claims. If claims are submitted on paper for Modifier 53, we expect that medical records will accompany the claim, without this information, your claim may be denied. Include office records, test results, operative notes, or hospital records to substantiate the reason for reporting a reduced service. If this information is not received, your claim may be denied.
One of the most common examples of modifier 53 (this is an exception to the rule) is when an incomplete colonoscopy is performed. Add modifier 53 to CPT code 45378. No documentation is required. |
| 54 |
Surgical care only - When one physician performs a surgical procedure and another
physician provides preoperative and/or postoperative management, the surgical service
should be identified by adding modifier 54 to the usual procedure code. |
| 55 |
Postoperative management only. When one physician performs the postoperative
management and another physician has performed the surgical procedure. |
| 57 |
Initial Decision for surgery (90-day global period). This modifier is used on E&M
service, the day before or the day of surgery to exempt it from the global surgery
package. |
| 58 |
Staged or related procedure or service by the same physician during the postoperative
period. If a less extensive procedure fails, and a more extensive procedure is required,
the second procedure is payable separately. Modifier 58 must be reported with the second
procedure. |
| 59 |
Distinct procedural service - The physician may need to indicate that a procedure or
service was distinct or separate from other services performed on the same day. This may
represent a different session or patient encounter, different procedure or surgery,
different site, separate lesion, or separate injury. However, when another already
established modifier is appropriate, it should be used rather than modifier 59. |
| 62 |
Two surgeons (co-surgery) - Under certain circumstances, the skills of two surgeons (usually with different skills) may be required in the management of a specific surgical procedure. Adding modifier 62 to the procedure code used by each surgeon should identify the separate service. |
| 66 |
Surgical team - Under some circumstance, highly complex procedures, requiring the accompanying services of several physicians, often of different specialties, plus other highly skilled specially trained personnel, and various types of complex equipment, are carried out under the surgical team concept. Claims with Modifier 66 cannot be processed without a copy of the Operative Report. If claims are submitted electronically with Modifier 66 we will request the operative report before we can process the claims. If claims are submitted on paper for Modifier 66, we expect the operative report will accompany the claim; without this information, your claim may be denied. |
| 73 |
Discontinued Out-Patient Hospital/Ambulatory Surgery Center (ASC) Procedure Prior to the Administration of
Anesthesia. |
| 74 |
Discontinued Out-Patient Hospital/Ambulatory Surgery Center (ASC) Procedure After Administration of

the repeat procedure in item 19 of the CMS 1500 Form or the electronic equivalent, |
| 77 |
Repeat procedure by another physician. Indicate the reason or the different times for
the repeat procedure in item 19 of the CMS 1500 Form or the electronic equivalent. |
| 78 |
Return to the operating room for a related procedure during the postoperative period.
The physician may need to indicate that another procedure was performed during the
postoperative period of the initial procedure. When this subsequent procedure is related
to the first, and requires the use of the operating room, it should be reported by adding
modifier 78 to the related procedure. |
| 79 |
Unrelated procedure or service by the same physician during the postoperative period.
The physician may need to indicate that the performance of a procedure or service during
the postoperative period was unrelated to the original procedure. |
| 80 |
Assistant surgeon. Add modifier 80 to the usual procedure in a non-teaching setting to
identify surgical assistant services |
| 82 |
Assistant surgeon when qualified resident surgeon not available in a teaching setting |
| 90 |
Reference (Outside) Laboratory - When laboratory procedures are performed by a party
other than the treating or reporting physician, the procedure may be identified by adding
the modifier 90 to the usual procedure number. For the Medicare program, this modifier is
used by Independent Clinical Laboratories when referring tests to a Reference Laboratory
for analysis. |
| 91 |
Repeat clinical diagnostic lab tests performed on same day to obtain subsequent
reportable test value(s). This modifier is used to report a separate specimen(s) taken at
a separate encounter. |
| 99 |
The Multi-Carrier System (MCS) will now allow you to send up to four modifiers per
line of service on your claims for both electronically submitted and paper claims. Please
indicate the pricing modifiers in the first two positions and processing or informational
modifiers in the third and fourth positions. Use modifier 99 when more than four
modifiers are needed on a line of service. In situations that require five or more
modifiers, indicate modifier 99 in the first modifier field on the line of service and the
remaining modifiers would be entered in the narrative field of an EMC claim or Item 19 of
a 1500 claim form. For Example: 79, RT, LT, QU, GA
99 in the first modifier field on the line of service
79, RT, LT, QU, GA in the narrative field of an EMC claim or Item 19 of a 1500 claim form
