Device specific C-codes replaced by category codes

Two codes are required to qualify for a transitional passthrough payment for devices—a CPT-4 code for the procedure performed and a C-code for the device inserted. C-codes are a special series of codes within HCPCS used only for pass-through items under OPPS (devices, drugs or biologicals). C-codes may not be used to bill services paid under other Medicare payment systems or other payors. C-codes were specific to a particular brand, trade name, or a specific model number.

Article Overview

This article covers the Medicare outpatient payment change that moved device billing away from item-specific HCPCS C-codes and toward category-based coding. It is relevant to hospitals, outpatient coding and billing staff, and device manufacturers who need to understand the transition period, related guidance, and the category structure used for qualifying devices. The discussion also addresses operational topics such as crosswalks, grace periods, multiple-component devices, kits, and reprocessed devices within the broader OPPS passthrough framework.

Why This Topic Matters

The change affects how hospitals report qualifying devices under OPPS and how they align billing practices with the newer category-code structure. It matters for compliant charge capture, device identification, and coordination with manufacturers during the transition period.

Article Sections

  1. Transitional passthrough payment and the move to category codes

    Introduces the shift from item-specific device reporting to category-based HCPCS coding under the outpatient prospective payment system. Summarizes the Medicare policy context and transition timeline.

  2. General eligibility and device classification guidance

    Outlines broad requirements and exclusions for devices under the transitional pass-through framework. Also discusses how the article distinguishes devices from supplies, equipment, and other nonqualifying items.

  3. General coding and billing instructions

    Provides high-level billing topics related to kits, multiple units, grace-period billing, and items with multiple components. It also notes how hospitals are directed to work with manufacturers and apply the new category structure.

  4. Reprocessed devices

    Addresses how reprocessed devices are treated in relation to single-use status and transitional pass-through payment eligibility. This section stays focused on the broader reprocessing context rather than specific coding outcomes.

  5. C-codes for categories

    Presents the category-code list associated with the device transition and includes examples of categories used for different device types. The section serves as the article’s main reference list for the new HCPCS device categories.
