Official Description

Therapeutic, prophylactic, or diagnostic injection (specify substance or drug); subcutaneous or intramuscular

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A therapeutic, prophylactic, or diagnostic injection refers to the administration of a specific substance or drug via subcutaneous or intramuscular routes. This procedure is essential in various medical contexts, as it allows for the delivery of medications directly into the body, facilitating immediate therapeutic effects. A subcutaneous injection involves placing the medication just beneath the skin into the fatty tissue, which is typically located in areas such as the abdomen, upper arm, upper leg, or buttocks. The process begins with cleansing the skin to minimize the risk of infection. A fold of skin is then pinched to create a stable surface for the injection, and the needle is inserted at an angle ranging from 45 to 90 degrees, depending on the specific technique and site. In contrast, an intramuscular injection is administered deeper into the muscle tissue, which allows for a more rapid systemic absorption of the medication. This method is particularly useful for delivering larger doses of medication that require quick action. Common sites for intramuscular injections include the gluteal muscles of the buttocks, the vastus lateralis muscle of the thigh, and the deltoid muscle of the upper arm, with the needle inserted at a 90-degree angle to ensure proper placement. Both methods are critical in clinical practice for the effective management of various health conditions, enabling healthcare providers to deliver necessary treatments efficiently and safely.

1. Indications

The therapeutic, prophylactic, or diagnostic injection is performed for various indications, which may include the following:

  • Therapeutic Use Administering medications to treat specific medical conditions or alleviate symptoms.
  • Prophylactic Use Providing preventive treatment to avert the onset of diseases or conditions.
  • Diagnostic Use Delivering substances that assist in diagnosing medical conditions through their effects or reactions in the body.

2. Procedure

The procedure for administering a therapeutic, prophylactic, or diagnostic injection involves several key steps, which are detailed as follows:

  • Step 1: Preparation The healthcare provider begins by preparing the injection site. This includes cleansing the skin with an antiseptic solution to reduce the risk of infection. The provider ensures that all necessary materials, including the syringe, needle, and medication, are ready for use.
  • Step 2: Subcutaneous Injection Technique For a subcutaneous injection, the provider pinches a 2-inch fold of skin between the thumb and forefinger. The needle is then inserted completely under the skin at an angle of 45 to 90 degrees using a quick, sharp thrust. This technique ensures that the medication is delivered into the fatty tissue just beneath the skin.
  • Step 3: Blood Check After inserting the needle, the provider retracts the plunger slightly to check for blood. If blood is aspirated into the syringe, it indicates that the needle may have entered a blood vessel, and a new injection site must be selected. If no blood is present, the provider proceeds to the next step.
  • Step 4: Medication Administration The medication is injected slowly into the tissue, allowing for proper absorption. Once the medication has been administered, the needle is withdrawn, and mild pressure is applied to the injection site to minimize bleeding and discomfort.
  • Step 5: Intramuscular Injection Technique For an intramuscular injection, the provider selects an appropriate muscle site, such as the gluteal muscles, vastus lateralis muscle, or deltoid muscle. The needle is inserted at a 90-degree angle to ensure that the medication is delivered deep into the muscle tissue, facilitating rapid systemic absorption.

3. Post-Procedure

After the injection, the patient is typically monitored for any immediate adverse reactions or side effects. The injection site may be observed for signs of swelling, redness, or infection. Patients are often advised to avoid strenuous activity at the injection site for a short period and to apply a bandage if necessary. Additionally, they may receive instructions on how to care for the injection site and when to seek medical attention if they experience unusual symptoms.

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.
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.
