HCPCS Level II code C9359 designates a porous purified collagen matrix bone void filler sold as putty (Integra Mozaik or Integra OS), reported per 0.5 cc. This code identifies a specific class of osteoconductive scaffold used to fill bone defects during surgical procedures, serving as a scaffold to support bone healing. Nationally, precise coding for bone graft substitutes affects device tracking, billing clarity, and consistency in reporting device-utilization across surgical specialties.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents, typical clinical settings where the product is used (hospital OR, ambulatory surgical center, outpatient surgical clinic), and the service type (bone graft substitute/osteoconductive scaffold placement).

The publication provides benchmarks and policy-relevant context related to device coding, utilization patterns, and payer coverage considerations where available. It also outlines clinical context for use in bone voids and surgically created defects. Data not available in the input is clearly noted where applicable.
