CPT Code 20610: Description

CPT code 20610 is used to represent a specific procedure in the medical field. In this case, it refers to the aspiration and/or injection of a major joint or bursa, such as the knee, shoulder, or hip. This procedure is commonly performed to relieve pain and inflammation in these areas.

Approximate Fee Amount

Fee: $64.12

The fee for CPT code 20610 can vary depending on several factors, including the geographic location, the healthcare provider, and the insurance coverage. On average, the fee for this procedure ranges from $100 to $500. However, it is important to note that these are just approximate figures and the actual fee may differ.

Insurance Guidelines

Documentation Requirements: It’s crucial that the patient’s medical record supports the medical necessity of the procedure, including detailed medical history, results of relevant diagnostic tests, and documented symptomatology reduction if treatment is repeated​ (CMS.gov)​.

Modifiers: Commonly used modifiers include JW (if part of the drug is wasted), RT, LT, and 50 (for bilateral procedures) to indicate the specific details of how and where the procedure was
performed​ .

Payer Specific Guidelines: Insurers might have specific guidelines, including the necessity for prior radiological exams and documentation supporting the initial diagnosis. The application of modifiers and billing separate line items for bilateral procedures can vary among commercial payers and should align with Medicare or other insurance requirements​ ​.

CPT Code 20610: Guidelines and Usage

Modifier Use: For unilateral procedures, the RT or LT modifiers are used. If the procedure is bilateral, modifier 50 is recommended. Modifier JW is applicable if there is any drug wastage during the procedure​​.

Medicare Considerations: For Medicare billing, any associated drug should also be included on the claim, and the medical necessity must be documented as per Medicare guidelines. The drug code is billed separately using the JW modifier​ .

Coding Guidelines
The aspiration and/or injection procedure code may be billed in addition to the drug. Indicate
which knee was injected by using the RT (right) or LT (left) modifier (FAO-10 electronically) on
the injection procedure (CPT 20610). Place the CPT code 20610 in item 24D. If the drug was
administered bilaterally, a -50 modifier should be used with 20610.
