ICD-10-PCS BL4 Imaging: Connective Tissue Ultrasonography

The ICD-10-PCS root operation Ultrasonography (code BL4) refers to an imaging procedure that uses ultrasound waves to visualize internal structures, specifically connective tissues in this classification. This operation captures detailed images without the need for invasive methods.

Within the Imaging section, Ultrasonography is applied to various body parts such as connective tissue and tendons of the extremities. For example, the code BL40ZZZ represents ultrasonography of the upper extremity connective tissue, while BL41ZZZ is the equivalent for the lower extremity connective tissue. Additionally, ultrasonography of upper extremity tendons corresponds to BL42ZZZ, and BL43ZZZ denotes the procedure on lower extremity tendons. These codes document the use of ultrasound imaging to assess musculoskeletal components with precision, aiding in diagnosis and treatment planning without causing tissue disruption.

List of ICD-10-PCS codes used to specify BL4 - Ultrasonography (real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves). There are a total of 5 procedure codes in this section.

  • BL4 - Imaging, Connective Tissue, Ultrasonography

  • BL40ZZZ - Ultrasonography of Upper Extremity Connective Tissue

  • BL41ZZZ - Ultrasonography of Lower Extremity Connective Tissue

  • BL42ZZZ - Ultrasonography of Upper Extremity Tendons

  • BL43ZZZ - Ultrasonography of Lower Extremity Tendons
