| 22 | http://www.ama-assn.org/go/cpt | Increased Procedural Services: When the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. Documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient''s condition, physical and mental effort required). Note: This modifier should not be appended to an E/M service. |
| 23 | http://www.ama-assn.org/go/cpt | Unusual Anesthesia: Occasionally, a procedure, which usually requires either no anesthesia or local anesthesia, because of unusual circumstances must be done under general anesthesia. This circumstance may be reported by adding modifier 23 to the procedure code of the basic service. |
| 24 | http://www.ama-assn.org/go/cpt | Unrelated Evaluation and Management Service by the Same Physician or Other Qualified Health Care Professional During a Postoperative Period: The physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. This circumstance may be reported by adding modifier 24 to the appropriate level of E/M service. |
| 25 | http://www.ama-assn.org/go/cpt | Significant, Separately Identifiable Evaluation and Management Service by the Same Physician or Other Qualified Health Care Professional on the Same Day of the Procedure or Other Service: It may be necessary to indicate that on the day a procedure or service identified by a CPT code was performed, the patient's condition required a significant, separately identifiable E/M service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. A significant, separately identifiable E/M service is defined or substantiated by documentation that satisfies the relevant criteria for the respective E/M service to be reported (see Evaluation and Management Services Guidelines for instructions on determining level of E/M service). The E/M service may be prompted by the symptom or condition for which the procedure and/or service was provided. As such, different diagnoses are not required for reporting of the E/M services on the same date. This circumstance may be reported by adding modifier 25 to the appropriate level of E/M service. Note: This modifier is not used to report an E/M service that resulted in a decision to perform surgery. See modifier 57 For significant, separately identifiable non-E/M services, see modifier 59. |
| 26 | http://www.ama-assn.org/go/cpt | Professional Component: Certain procedures are a combination of a physician or other qualified health care professional component and a technical component. When the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. |
| 32 | http://www.ama-assn.org/go/cpt | Mandated Services: Services related to mandated consultation and/or related services (eg, third party payer, governmental, legislative or regulatory requirement) may be identified by adding modifier 32 to the basic procedure |
| 33 | http://www.ama-assn.org/go/cpt | Preventive Services: When the primary purpose of the service is the delivery of an evidence based service in accordance with a US Preventive Services Task Force A or B rating in effect and other preventive services identified in preventive services mandates (legislative or regulatory), the service may be identified by adding 33 to the procedure. For separately reported services specifically identified as preventive, the modifier should not be used |
| 47 | http://www.ama-assn.org/go/cpt | Anesthesia by Surgeon: Regional or general anesthesia provided by the surgeon may be reported by adding modifier 47 to the basic service. (This does not include local anesthesia.) Note: Modifier 47 would not be used as a modifier for the anesthesia procedures. |
| 50 | http://www.ama-assn.org/go/cpt | Bilateral Procedure: Unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. Note: This modifier should not be appended to designated "add-on" codes (see Appendix D) |
| 51 | http://www.ama-assn.org/go/cpt | Multiple Procedures: When multiple procedures, other than E/M services, Physical Medicine and Rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. The additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). Note: This modifier should not be appended to designated "add-on" codes (see Appendix D) |
| 52 | http://www.ama-assn.org/go/cpt | Reduced Services: Under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. Under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. This provides a means of reporting reduced services without disturbing the identification of the basic service. Note: For hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for ASC hospital outpatient use). |
| 53 | http://www.ama-assn.org/go/cpt | Discontinued Procedure: Under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. Due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. This circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. Note: This modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. For outpatient hospital/ambulatory surgery center (ASC) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for ASC hospital outpatient use) |
| 54 | http://www.ama-assn.org/go/cpt | Surgical Care Only: When 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number |
| 55 | http://www.ama-assn.org/go/cpt | Postoperative Management Only: When 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number |
| 56 | http://www.ama-assn.org/go/cpt | Preoperative Management Only: When 1 physician or other qualified health care professional performed the preoperative care and evaluation and another performed the surgical procedure, the preoperative component may be identified by adding modifier 56 to the usual procedure number |
| 57 | http://www.ama-assn.org/go/cpt | Decision for Surgery: An evaluation and management service that resulted in the initial decision to perform the surgery may be identified by adding modifier 57 to the appropriate level of E/M service. |
| 58 | http://www.ama-assn.org/go/cpt | Staged or Related Procedure or Service by the Same Physician or Other Qualified Health Care Professional During the Postoperative Period: It may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. This circumstance may be reported by adding modifier 58 to the staged or related procedure. Note: For treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78 |
| 59 | http://www.ama-assn.org/go/cpt | Distinct Procedural Service: Under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-E/M services performed on the same day. Modifier 59 is used to identify procedures/services, other than E/M services, that are not normally reported together, but are appropriate under the circumstances. Documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. However, when another already established modifier is appropriate it should be used rather than modifier 59. Only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. Note: Modifier 59 should not be appended to an E/M service. To report a separate and distinct E/M service with a non-E/M service performed on the same date, see modifier 25 |
| 62 | http://www.ama-assn.org/go/cpt | Two Surgeons: When 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. Each surgeon should report the co-surgery once using the same procedure code. If additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. Note: If a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate |
| 63 | http://www.ama-assn.org/go/cpt | Procedure Performed on Infants less than 4 kg: Procedures performed on neonates and infants up to a present body weight of 4 kg may involve significantly increased complexity and physician or other qualified health care professional work commonly associated with these patients. This circumstance may be reported by adding modifier 63 to the procedure number. Note: Unless otherwise designated, this modifier may only be appended to procedures/services listed in the 20100-69990 code series and 92920, 92928, 92953, 92960, 92986, 92987, 92990, 92997, 92998, 93312, 93313, 93314, 93315, 93316, 93317, 93318, 93452, 93505, 93563, 93564, 93568, 93569, 93573, 93574, 93575, 93580, 93581, 93582, 93590, 93591, 93592, 93593, 93594, 93595, 93596, 93597, 93598, 93615, 93616 from the Medicine/Cardiovascular section. Modifier 63 should not be appended to any CPT codes listed in the Evaluation and Management Services, Anesthesia, Radiology, Pathologyand Laboratory, or Medicine sections (other than those identified above from the Medicine/Cardiovascular section) |
| 66 | http://www.ama-assn.org/go/cpt | Surgical Team: Under some circumstances, highly complex procedures (requiring the concomitant services of several physicians or other qualified health care professionals, often of different specialties, plus other highly skilled, specially trained personnel, various types of complex equipment) are carried out under the "surgical team" concept. Such circumstances may be identified by each participating individual with the addition of modifier 66 to the basic procedure number used for reporting services |
| 76 | http://www.ama-assn.org/go/cpt | Repeat Procedure or Service by Same Physician or Other Qualified Health Care Professional: It may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. This circumstance may be reported by adding modifier 76 to the repeated procedure or service. Note: This modifier should not be appended to an E/M service |
| 77 | http://www.ama-assn.org/go/cpt | Repeat Procedure by Another Physician or Other Qualified Health Care Professional: It may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. This circumstance may be reported by adding modifier 77 to the repeated procedure or service. Note: This modifier should not be appended to an E/M service. |
| 78 | http://www.ama-assn.org/go/cpt | Unplanned Return to the Operating/Procedure Room by the Same Physician or Other Qualified Health Care Professional Following Initial Procedure for a Related Procedure During the Postoperative Period: It may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). When this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (For repeat procedures, see modifier 76. |
| 79 | http://www.ama-assn.org/go/cpt | Unrelated Procedure or Service by the Same Physician or Other Qualified Health Care Professional During the Postoperative Period: The individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. This circumstance may be reported by using modifier 79. (For repeat procedures on the same day, see modifier 76. |
| 80 | http://www.ama-assn.org/go/cpt | Assistant Surgeon: Surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). |
| 81 | http://www.ama-assn.org/go/cpt | Minimum Assistant Surgeon: Minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number. |
| 82 | http://www.ama-assn.org/go/cpt | Assistant Surgeon (when qualified resident surgeon not available): The unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s). |
| 90 | http://www.ama-assn.org/go/cpt | Reference (Outside) Laboratory: When laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number |
| 91 | http://www.ama-assn.org/go/cpt | Repeat Clinical Diagnostic Laboratory Test: In the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. Under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. Note: This modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. This modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). This modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient |
| 92 | http://www.ama-assn.org/go/cpt | Alternative Laboratory Platform Testing: When laboratory testing is being performed using a kit or transportable instrument that wholly or in part consists of a single use, disposable analytical chamber, the service may be identified by adding modifier 92 to the usual laboratory procedure code (HIV testing 86701-86703, and 87389). The test does not require permanent dedicated space, hence by its design may be hand carried or transported to the vicinity of the patient for immediate testing at that site, although location of the testing is not in itself determinative of the use of this modifier |
| 93 | http://www.ama-assn.org/go/cpt | Synchronous Telemedicine Service Rendered Via Telephone or Other Real-Time Interactive Audio-Only Telecommunications System : Synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located away at a distant site from the physician or other qualified health care professional. The totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction |
| 95 | http://www.ama-assn.org/go/cpt | Synchronous Telemedicine Service Rendered Via a Real-Time Interactive Audio and Video Telecommunications System: Synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. The totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. Modifier 95 may only be appended to the services listed in Appendix P. Appendix P is the list of CPT codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system |
| 96 | http://www.ama-assn.org/go/cpt | Habilitative Services: When a service or procedure that may be either habilitative or rehabilitative in nature is provided for habilitative purposes, the physician or other qualified health care professional may add modifier 96 to the service or procedure code to indicate that the service or procedure provided was a habilitative service. Habilitative services help an individual learn skills and functioning for daily living that the individual has not yet developed, and then keep and/or improve those learned skills. Habilitative services also help an individual keep, learn, or improve skills and functioning for daily living |
| 97 | http://www.ama-assn.org/go/cpt | Rehabilitative Services: When a service or procedure that may be either habilitative or rehabilitative in nature is provided for rehabilitative purposes, the physician or other qualified health care professional may add modifier 97 to the service or procedure code to indicate that the service or procedure provided was a rehabilitative service. Rehabilitative services help an individual keep, get back, or improve skills and functioning for daily living that have been lost or impaired because the individual was sick, hurt, or disabled |
| 99 | http://www.ama-assn.org/go/cpt | Multiple Modifiers: Under certain circumstances 2 or more modifiers may be necessary to completely delineate a service. In such situations modifier 99 should be added to the basic procedure, and other applicable modifiers may be listed as part of the description of the service. |

| 27 | http://www.ama-assn.org/go/cpt | Multiple Outpatient Hospital E/M Encounters on the Same Date: For hospital outpatient reporting purposes, utilization of hospital resources related to separate and distinct E/M encounters performed in multiple outpatient hospital settings on the same date may be reported by adding modifier 27 to each appropriate level outpatient and/or emergency department E/M code(s). This modifier provides a means of reporting circumstances involving evaluation and management services provided by physician(s) in more than one (multiple) outpatient hospital setting(s) (eg, hospital emergency department, clinic). Note: This modifier is not to be used for physician reporting of multiple E/M services performed by the same physician on the same date. For physician reporting of all outpatient evaluation and management services provided by the same physician on the same date and performed in multiple outpatient setting(s) (eg, hospital emergency department, clinic), see Evaluation and Management, Emergency Department, or Preventive Medicine Services codes |
| 73 | http://www.ama-assn.org/go/cpt | Discontinued Out-Patient Hospital/Ambulatory Surgery Center (ASC) Procedure Prior to the Administration of Anesthesia: Due to extenuating circumstances or those that threaten the well being of the patient, the physician may cancel a surgical or diagnostic procedure subsequent to the patient's surgical preparation (including sedation when provided, and being taken to the room where the procedure is to be performed), but prior to the administration of anesthesia (local, regional block(s) or general). Under these circumstances, the intended service that is prepared for but cancelled can be reported by its usual procedure number and the addition of modifier 73. Note: The elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. For physician reporting of a discontinued procedure, see modifier 53. |
| 74 | http://www.ama-assn.org/go/cpt | Discontinued Out-Patient Hospital/Ambulatory Surgery Center (ASC) Procedure After Administration of Anesthesia: Due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). Under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. Note: The elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. For physician reporting of a discontinued procedure, see modifier 53. |
