About the 0ST Code Range
The ICD-10-PCS root operation Resection (code prefix 0ST) refers to the surgical removal of all or a portion of a body part. In the Medical and Surgical section, this operation specifically applies to the Lower Joints, involving removal of various spinal discs and joints in the pelvic and lower extremity regions.
This classification includes codes for resections performed by an Open Approach on structures such as the Lumbar Vertebral Disc (code 0ST20ZZ), Lumbosacral Disc (0ST40ZZ), and joints including the Sacroiliac, Hip, Knee, Ankle, and Tarsal Joints (e.g., 0ST70ZZ for right sacroiliac joint, 0ST90ZZ for right hip joint). Each code precisely identifies the specific joint or disc targeted, along with laterality when applicable, such as right or left hip or knee joints. Correct use of these lower joints resection codes is essential for accurate procedural documentation and reporting in surgical cases involving joint removal or excision of spinal disc components.
