CPT 22511 covers a minimally invasive procedure where a physician injects bone cement into a damaged or fractured vertebra in the lower back using a needle through the skin. This helps stabilize compression fractures and relieve pain without open surgery.

Billing tips
Verify site-of-service designation before scheduling as non-facility setting yields $1282.86 more per procedure
Impact: Site-of-service optimization can increase revenue by 326% compared to facility setting
Do NOT separately bill fluoroscopy codes (77002, 77003) as imaging guidance is included in 22511
Impact: Prevents automatic denials and audit flags; unbundling can result in recoupment of $150-300 per case
Bill additional levels using add-on codes 22512 (lumbar/sacral) or equivalent thoracic codes, never multiple units of 22511
Impact: Correct add-on code usage ensures payment for multiple levels; billing multiple units of 22511 will be denied
Document cement volume injected, fluoroscopic images obtained, and vertebral level treated with anatomic landmarks
Impact: Complete documentation reduces audit risk and denial rate by approximately 40%
Obtain pre-authorization for Medicare Advantage and commercial payers as most require prior approval
Impact: Pre-authorization prevents 100% denial; appeals success rate without pre-auth is only 30-40%
Ensure diagnosis code reflects acute fracture (not chronic pain) with specificity to vertebral level
Impact: Appropriate diagnosis coding increases first-pass approval rate by 60%; M80.08XA (osteoporotic fracture) supports medical necessity better than M54.5 (low back pain)
