Pulmonary angiography is a specialized vascular imaging procedure designed to assess blood flow within the lungs. This technique is crucial for evaluating the condition of the pulmonary vasculature, which includes the arteries and veins responsible for transporting blood to and from the lungs. The primary purpose of this procedure is to visualize the integrity of the vessel walls, allowing for the diagnosis of various vascular abnormalities such as narrowing (stenosis) or blockages (embolism) that can impede blood flow. Additionally, pulmonary angiography is instrumental in identifying and treating conditions like embolisms, arteriovenous malformations, pseudoaneurysms, and cavitary or inflammatory lung lesions. It can also be utilized to retrieve foreign objects, such as catheter fragments or inferior vena cava filters, that may pose a risk to the patient’s health. During the procedure, a large bore needle is typically inserted into a blood vessel located in the groin or neck. A guidewire is then introduced through the needle, followed by the advancement of a catheter over the guidewire. This catheter is carefully navigated through the right side of the heart and into the main pulmonary artery, all under imaging guidance to ensure precision. In a nonselective pulmonary angiography study, dye is injected into the main pulmonary artery, allowing for real-time observation of blood flow. In contrast, a selective study involves advancing the catheter into the right and/or left arteries that branch off from the main pulmonary artery, reaching the smaller lobar or segmental branches of the pulmonary vasculature. Following the injection of dye in a selective study, images are captured and analyzed in real time, providing detailed insights into the pulmonary circulation. The procedure encompasses the radiologist's supervision, interpretation of the findings, and the generation of a written report, which may include consultations with referring physicians regarding the diagnosis and potential need for further testing or interventions.

The indications for performing a pulmonary angiography include the following:
The procedure for pulmonary angiography involves several critical steps, which are outlined as follows:
After the completion of the pulmonary angiography, the patient is monitored for any immediate complications or adverse reactions to the contrast dye. It is essential to assess the insertion site for signs of bleeding or infection. Patients may be advised to rest and avoid strenuous activities for a specified period to facilitate recovery. Follow-up imaging or additional tests may be recommended based on the findings of the angiography. The radiologist will typically consult with the referring physician to discuss the results and any further management plans that may be required.

| 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. | 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. | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | GC | This service has been performed in part by a resident under the direction of a teaching physician | 22 | 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. | 51 | 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 | 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). | 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. | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | CR | Catastrophe/disaster related | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GW | Service not related to the hospice patient's terminal condition | 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 | 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 | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
