Official Description

Subcutaneous injection of filling material (eg, collagen); 1.1 to 5.0 cc

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 11951 involves the subcutaneous injection of a filling material, which is typically collagen. This procedure is performed to enhance the appearance of the skin by addressing various dermatological issues such as acne scars and facial wrinkles. The injection is administered beneath the skin's surface, allowing the filling material to provide volume and support to the affected areas. The specific volume of the filling material used in this procedure ranges from 1.1 to 5.0 cc, which distinguishes it from other related codes that correspond to different volumes of injection. For instance, CPT® Code 11950 is designated for injections of 1 cc or less, while CPT® Code 11952 is used for injections ranging from 5.1 to 10.0 cc, and CPT® Code 11954 is for injections exceeding 10.0 cc. This structured approach to coding ensures that the specific details of the procedure are accurately captured for billing and documentation purposes.

1. Indications

The subcutaneous injection of filling material, as described by CPT® Code 11951, is indicated for various dermatological conditions. These include:

  • Acne Scars The procedure is often performed to improve the appearance of acne scars, which can be a source of distress for many patients.
  • Facial Wrinkles This injection is also utilized to reduce the visibility of facial wrinkles, helping to restore a more youthful appearance.
  • Dermatological Defects Other skin imperfections that may benefit from this procedure include fine lines and volume loss in specific areas of the face.

2. Procedure

The procedure for the subcutaneous injection of filling material involves several key steps:

  • Preparation of the Injection Site The physician begins by cleaning the area where the injection will be administered to minimize the risk of infection. This may involve the use of antiseptic solutions to ensure the skin is properly disinfected.
  • Selection of Filling Material The physician selects the appropriate filling material, typically collagen, based on the specific needs of the patient and the area being treated. The volume of the material is measured to ensure it falls within the range of 1.1 to 5.0 cc for this particular code.
  • Administration of the Injection Using a sterile syringe, the physician carefully injects the filling material subcutaneously. The injection technique may vary depending on the area being treated, and the physician may use a series of small injections to achieve the desired effect.
  • Post-Injection Assessment After the injection, the physician assesses the treated area to ensure that the filling material has been distributed evenly and that the desired cosmetic effect has been achieved. Any immediate reactions or complications are monitored closely.

3. Post-Procedure

Following the subcutaneous injection of filling material, patients may experience some swelling, redness, or tenderness at the injection site, which is typically temporary. The physician may provide specific aftercare instructions, such as avoiding strenuous activities or exposure to extreme temperatures for a short period. Patients are usually advised to monitor the injection site for any signs of infection or unusual reactions and to follow up with the physician if any concerns arise. The expected recovery time is generally minimal, allowing patients to resume normal activities shortly after the procedure.

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.
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).
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.)
82 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).
