Ultrasound is an easy way to confirm a Bakers cyst and rule out other lumps. At Sportdoctorlondon, we will often perform a Bakers cyst drainage using ultrasound. Also, we may inject the knee joint at the same time if there is excess joint fluid. Dr. Masci is a specialist sport doctor in London. He specialises in muscle, tendon and joint injuries.
Symptoms of a Baker’s cyst may include:
M71.21 is a billable diagnosis code used to specify a medical diagnosis of synovial cyst of popliteal space [baker], right knee. The code M71.21 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
CPT 10160 - Puncture aspiration of abscess, hematoma, bulla, or cyst. For imaging guidance, Check 76942, 77012, 77021. Procedure description: The patient is appropriately prepped and anesthetized by local anesthesia, the physician inserts a sterile needle into the cyst using imaging guidance. He then withdraws the fluid from the cyst.
ICD-10 Code for Synovial cyst of popliteal space [Baker], right knee- M71. 21- Codify by AAPC.
Synovial cyst of popliteal space [Baker], right knee M71. 21 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM M71. 21 became effective on October 1, 2021.
A Baker's cyst can form when joint-lubricating fluid fills a cushioning pouch (bursa) at the back of your knee. A Baker's cyst is a fluid-filled cyst that causes a bulge and a feeling of tightness behind your knee. The pain can get worse when you fully flex or extend your knee or when you're active.
A Baker cyst is seen medially (arrowhead). Transverse ultrasonographic image of the knee in a patient who had recent arthroscopy shows a complex, cystic mass (arrow) in the medial aspect of popliteal fossa. The mass communicates with the knee joint (arrowhead), which is consistent with a Baker cyst.

ICD-10-CM Code for Effusion, left knee M25. 462.
The condition is named after the 19th century surgeon who first described it, Dr. William Morrant Baker. Baker's cysts typically result from a problem inside the knee joint, such as osteoarthritis or a meniscus tear. These conditions cause the joint to produce excess fluid, which can lead to the formation of a cyst.
A Baker cyst is a fluid-filled sac that forms behind the knee. It's also known as a popliteal cyst or popliteal synovial cyst. The knee is a complex joint that has many parts. The lower end of the thighbone (femur) rotates on the upper end of the shinbone (tibia).
The popliteal arteries branch from the femoral arteries in your legs to deliver blood to your knees and lower legs. They run behind your kneecap, where you can feel the popliteal pulse.
The knee contains sacs of fluid, called bursa, that help to cushion the joint and reduce friction between the structures around it. A Baker's cyst is a swelling on the back of the knee, caused by a build-up of excess fluid inside the bursa.
A popliteal or Baker cyst is not technically a true cyst, but more of a distended knee joint recess that in most adult people communicates with the gastrocnemius- semimembranosus bursa and has accumulated fluid.
Ganglion cysts are filled with gelatinous and viscous fluid in the neighbourhood of joints or tendon sheaths. They are frequently seen at joints and tendons of the wrist but are rare in the region of knee joint. The most common cysts in the knee region are popliteal also called Baker's cysts.
This is not a "true" cyst, as an open communication with the synovial sac is often maintained. Specialty: Rheumatology. MeSH Code: D011151. ICD 9 Code: 727.51. Schematic drawing of a Baker's cyst.
The ICD code M712 is used to code Baker's cyst. A Baker's cyst, also known as a popliteal cyst, is a benign swelling of the semimembranosus or more rarely some other synovial bursa found behind the knee joint. It is named after the surgeon who first described it, William Morrant Baker (1838–1896). This is not a "true" cyst, as an open communication ...
In adults, a Popliteal Cyst is an extension of the Knee Joint. The cyst is a swelling/fluid collection in a bursa between the Semitendinosus and Medial Gastrocnemius Tendons deep behind the knee. For what it is worth, all humans have the potential of developing a "cyst" from this bursa. There is a connection between the joint and the bursa, ...
The fluid in the cyst is joint fluid derived, but if there long enough can become syrupy or even thicker and gelatinous. The problem is that the fluid flow is usually only one direction, from the joint into the cyst, and usually does not flow backwards from the cyst into the joint.
Even if the joint inflammation resolves and excess fluid formation stops (i.e. the effusion resolves), the cyst may remain distended/full. If large and tight enough it can cause symptoms. There probably some patients that have "two way" fluid flow, but they are infrequent in my experience.
So, the aspiration and injection (if done) of the cyst is in essence a treatment of the knee joint, and 20610 would be correct.
