Photodynamic therapy (PDT) is a medical procedure that utilizes photosensitive or photoreactive chemicals in conjunction with light to effectively target and destroy premalignant lesions located on the skin and adjacent mucosa. This therapy involves the topical application of these photoreactive agents to all lesions within a designated anatomical area, which may include regions such as the face or scalp. The process begins with the preparation of the lesions, which may involve the removal of any overlying crust or scale to ensure optimal contact between the photoreactive chemicals and the skin. Following this preparation, the photosensitizing drugs are applied to the lesions, and the area is subsequently illuminated with light of a specific wavelength. This light activation is crucial as it triggers a chemical reaction that leads to the destruction of the targeted lesions. The CPT® Code 96573 specifically refers to the provision of this therapy by a physician or other qualified healthcare professional, and it is important to note that this code is reported once per day for the photodynamic therapy performed.

The indications for photodynamic therapy (PDT) using CPT® Code 96573 include the treatment of premalignant lesions of the skin and adjacent mucosa. These lesions may present as actinic keratosis or other similar conditions that have the potential to progress to malignancy if left untreated. PDT is particularly indicated for patients who require a non-invasive treatment option to manage these lesions effectively.
The procedure for photodynamic therapy as described by CPT® Code 96573 involves several key steps that ensure the effective treatment of the lesions. First, the physician or qualified healthcare professional prepares the lesion(s) by removing any overlying crust or scale. This step is crucial as it enhances the efficacy of the photoreactive chemicals by allowing them to penetrate the skin more effectively. Next, the photoreactive chemicals are applied topically to all identified lesions within the specific anatomical area being treated, such as the face or scalp. After the application of these chemicals, the area is subjected to illumination with light of the appropriate wavelength. This light activation is essential, as it triggers the photochemical reaction necessary for the destruction of the lesions. The entire procedure is performed in a single session, and CPT® Code 96573 is reported once per day for the photodynamic therapy provided.
After the photodynamic therapy procedure, patients may experience some localized reactions, such as redness, swelling, or discomfort in the treated area. These reactions are typically mild and resolve within a few days. It is important for patients to follow any post-procedure care instructions provided by the healthcare professional, which may include avoiding sun exposure and using specific topical treatments to aid in the healing process. Regular follow-up appointments may be necessary to monitor the treatment area and assess the effectiveness of the therapy.

| 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. | 79 | 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.) | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | GA | Waiver of liability statement issued as required by payer policy, individual case | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | GC | This service has been performed in part by a resident under the direction of a teaching physician | 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. | 24 | 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 | 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. | 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). | 58 | 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. | 78 | 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.
