How To Use CPT Code 27345

CPT 27345 describes the excision of a synovial cyst, commonly known as a Baker’s cyst, from the popliteal space to alleviate pain and improve range of motion. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 27345?

CPT 27345 can be used to describe the surgical removal of a synovial cyst, also known as a Baker’s cyst, from the popliteal space. This procedure is performed to relieve pain and improve the range of motion in the affected knee.

2. Official Description

The official description of CPT code 27345 is the “Excision of synovial cyst of popliteal space (eg, Baker’s cyst).” This code specifically refers to the removal of a synovial cyst from the back of the knee.

3. Procedure

1. To perform CPT 27345, the healthcare provider begins by making an incision over the popliteal space and extending it to the fascia.
2. Once access to the cyst is gained, the provider excises the cyst along with a portion of the gastrocnemius muscle.
3. The site is then flushed with sterile saline to ensure cleanliness.
4. Hemostasis is achieved to control any bleeding, and the site is closed with sutures in layers.

4. Qualifying circumstances

CPT 27345 is used when a patient presents with a Baker’s cyst, which is a fluid-filled pouch at the back of the knee that causes pain and cramps, particularly during knee movements. The excision of the cyst is performed to alleviate these symptoms and improve the patient’s quality of life.

5. When to use CPT code 27345

CPT code 27345 should be used when a healthcare provider performs the excision of a synovial cyst, specifically a Baker’s cyst, from the popliteal space. It is important to note that this code represents a unilateral service, meaning it is performed on one knee. If the procedure is performed on both knees, modifiers such as 50, RT, and LT should be appended based on payer preference.

6. Documentation requirements

To support a claim for CPT 27345, the healthcare provider must document the following information:

• Patient’s diagnosis of a Baker’s cyst
• Details of the procedure, including the incision, excision of the cyst, and closure of the site

• Signature of the healthcare provider performing the procedure

When billing for CPT 27345, ensure that the procedure is performed on a synovial cyst in the popliteal space. It is important to follow payer preferences regarding the use of modifiers, such as 50, RT, and LT, when the procedure is performed on both knees.
