The CPT® Code 71100 refers to a radiologic examination of the ribs, specifically a unilateral examination that includes two views. This procedure is commonly performed to assess the rib cage following trauma, with the primary goal of identifying any fractures or internal injuries that may not be immediately visible. Rib radiographs, or X-rays, are essential diagnostic tools in emergency and trauma settings, as they help clinicians evaluate the integrity of the rib structure and surrounding tissues. The two standard views utilized in this examination are the anteroposterior (AP) view, which captures a frontal image of the ribs, and an oblique view, which provides a different angle to enhance visualization of potential injuries. In the oblique views, the patient is positioned at a 45-degree angle to the X-ray cassette, allowing for a comprehensive assessment of the ribs on the side being examined. The procedure is designed to ensure that the area of interest is adequately imaged, facilitating accurate diagnosis and subsequent management. The distinction between this code and related codes, such as 71101, 71110, and 71111, lies in the number of views obtained and whether the examination is unilateral or bilateral. The physician is responsible for reviewing the resulting images, identifying any abnormalities, and documenting a written interpretation of the findings, which is crucial for guiding further clinical decisions.

Radiologic examination of the ribs using CPT® Code 71100 is indicated in the following scenarios:
The procedure for CPT® Code 71100 involves the following steps:
After the radiologic examination is completed, the physician reviews the obtained images for any signs of abnormalities, such as fractures or other injuries. The physician will document their findings in a written report, which is essential for guiding further clinical management. Patients may be advised on any necessary follow-up care or additional imaging if required. Recovery from the procedure is typically immediate, as it is non-invasive and does not require any special post-procedure care.

| 26 | 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. | RT | Right side (used to identify procedures performed on the right side of the body) | LT | Left side (used to identify procedures performed on the left side of the body) | TC | Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles | X5 | Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician | FY | X-ray taken using computed radiography technology/cassette-based imaging | GW | Service not related to the hospice patient's terminal condition | 59 | 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. | GC | This service has been performed in part by a resident under the direction of a teaching physician | Q6 | Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | X4 | Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period | 52 | 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). | GA | Waiver of liability statement issued as required by payer policy, individual case | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | 50 | 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). | 76 | 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 | 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. | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | CG | Policy criteria applied | CR | Catastrophe/disaster related | F2 | Left hand, third digit | F4 | Left hand, fifth digit | FX | X-ray taken using film | GP | Services delivered under an outpatient physical therapy plan of care | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | GZ | Item or service expected to be denied as not reasonable and necessary | KX | Requirements specified in the medical policy have been met | MA | Ordering professional is not required to consult a clinical decision support mechanism due to service being rendered to a patient with a suspected or confirmed emergency medical condition | PC | Wrong surgery or other invasive procedure on patient | PD | Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days | Q5 | Service furnished under a reciprocal billing arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | QJ | Services/items provided to a prisoner or patient in state or local custody, however the state or local government, as applicable, meets the requirements in 42 cfr 411.4 (b) | SA | Nurse practitioner rendering service in collaboration with a physician | T1 | Left foot, second digit | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XP | Separate practitioner, a service that is distinct because it was performed by a different practitioner | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
