Orthopedic Coding Alert

Insurers that reimburse operating microscope are very finicky Before you assign 69990 every time the orthopedic surgeon uses the operating microscope, you must determine whether your payer follows CPT guidelines or CMS guidelines.
 
For non-Medicare payers that don't follow National Correct Coding Initiative guidelines, you can find instructions for when to report +69990 (Microsurgical techniques, requiring use of operating microscope [list separately in addition to code for primary procedure]) in a note preceding the code descriptor in the CPT manual.
 
Specifically, CPT instructs that you should not report 69990 with bone graft and osteocutaneous flap codes 20955-20973, toe-to-hand transfer codes 26551-26554, toe joint transfer code 26556, diskectomy codes 63075-63078, internal neurolysis code 64727, or sympathectomy procedures 64820-64823.
 
For all other procedures, you may report 69990 separately if the surgeon documents using the operating microscope for microdissection during the procedure. Apply 69990 Mainly to Hand, Spine Surgery Orthopedic practices most often encounter documentation of the operating microscope during hand and spine surgeries. Hand surgeons mainly use microdissection -for blood vessels and nerve repair, including free tissue transfer where vessels are usually done with the scope,- says Douglas T. Hutchinson, MD, a practicing hand surgeon and associate professor at the University of Utah Orthopaedic Center. 
 
For example: The orthopedic surgeon dictates that he used the operating microscope for microdissection during suture of a single digital nerve of the hand (64831, Suture of digital nerve, hand or foot; one nerve). In this case, you can report 69990 in addition to 64831.
 
Remember: Because 69990 is an add-on code and is valued for intraoperative work only, you do not need to append modifier 51 (Multiple procedures). Don't Bill Multiple Units of 69990 Once Per Session Because 69990 is considered a -primary procedure,- you can only report it once per operative session no matter how many times you use the operating microscope while in the OR. -We only code 69990 once per session,- says Susan Posten, CPC, coder at the Houston Center for Spinal Reconstruction and Disc Replacement.
  
Even if the surgeon addresses separate spinal levels during a procedure, you should only list one unit of 69990 on your claim.
 
In black and white: According to the Regence Blue Shield of Idaho policy, -Code 69990 is eligible for reimbursement once per operative session and not per procedure code.- CMS Limits When You Can Bill Medicare payers, or any payer that follows NCCI guidelines, allow you to report 69990 in far fewer circumstances than payers that follow CPT guidelines.
 
Specifically, the Medicare Carriers Manual, section 15055, allows separate payment for use of the operating microscope only with procedures 61304-61546, 61550-61711, 62010-62100, 63081-63308, 63704-63710, 64831, 64834-64836, 64840-64858, 64861-64870, 64885-64898 and 64905-64907.
 
For all other procedures, Medicare considers the operating microscope an inclusive component of the [...]
