Official Description

Cryotherapy (CO2 slush, liquid N2) for acne

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

CPT® Code 17340 refers to the procedure of cryotherapy specifically for the treatment of acne. This method utilizes cryotherapy techniques, which include the application of CO2 slush or liquid nitrogen (N2), to freeze surface skin lesions associated with acne. The procedure is designed to target and treat these lesions effectively by applying extreme cold to the affected areas. The freezing process can be performed using various tools such as cryospray, a cryoprobe, or a cotton-tipped applicator. Each lesion is typically treated for a few seconds, and if necessary, a double freeze-thaw cycle may be employed, where the lesion is treated a second time to enhance the effectiveness of the treatment. This approach is an alternative to chemical exfoliation methods, which involve the use of chemical agents to remove layers of skin. In contrast, cryotherapy directly freezes the lesions, providing a different mechanism of action in the management of acne. The procedure is part of a broader range of dermatological treatments aimed at alleviating the symptoms of acne and improving the overall appearance of the skin.

1. Indications

The procedure described by CPT® Code 17340 is indicated for the treatment of acne, specifically targeting surface skin lesions that are symptomatic of this condition. The following are the explicit indications for performing cryotherapy for acne:

  • Active Acne Lesions The procedure is performed on patients presenting with active acne lesions that require intervention to reduce inflammation and promote healing.
  • Surface Skin Lesions Cryotherapy is indicated for the treatment of surface skin lesions that are visible and may be contributing to the patient's acne condition.

2. Procedure

The procedure for CPT® Code 17340 involves several key steps to ensure effective treatment of acne lesions through cryotherapy. The following procedural steps are outlined:

  • Preparation of the Treatment Area The physician prepares the treatment area by cleaning the skin to remove any oils, dirt, or makeup that may interfere with the effectiveness of the cryotherapy. This step is crucial to ensure that the cryotherapy can be applied directly to the lesions without obstruction.
  • Application of Cryotherapy The physician applies cryotherapy using one of several methods, including cryospray, a cryoprobe, or a cotton-tipped applicator. The selected method allows for precise application of the freezing agent to the targeted acne lesions. Each lesion is treated for a few seconds, ensuring that the freezing effect penetrates adequately to achieve the desired therapeutic outcome.
  • Double Freeze-Thaw Cycle (if necessary) If the physician determines that a double freeze-thaw cycle is required for optimal treatment, the lesion is subjected to a second application of cryotherapy after a brief thawing period. This additional treatment can enhance the effectiveness of the procedure by ensuring that the lesion is thoroughly frozen.
  • Alternative Exfoliation Method In some cases, the physician may choose to exfoliate the entire surface of the involved area of skin using a cotton-tipped applicator. This method involves applying the cryotherapy agent over a broader area to treat multiple lesions simultaneously.

3. Post-Procedure

After the cryotherapy procedure is completed, patients may experience some immediate effects, such as redness, swelling, or a slight burning sensation in the treated areas. These symptoms are typically temporary and should resolve within a few hours to a few days. Patients are advised to avoid sun exposure and to follow any specific aftercare instructions provided by the physician to promote healing and minimize the risk of complications. Monitoring the treated areas for any signs of infection or adverse reactions is also recommended. Follow-up appointments may be scheduled to assess the effectiveness of the treatment and to determine if additional sessions are necessary for optimal results.

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).
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.
GA Waiver of liability statement issued as required by payer policy, individual case
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.
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.
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.)
