What A2009 covers
A2009 identifies Symphony wound matrix supplied for application to a wound. It is a product-specific supply code, not a general code for any skin substitute or wound covering. Wound care clinicians and surgeons may use the matrix during treatment of an open wound in an office, hospital outpatient department, or other setting where the related procedure is performed.
Report the quantity in square centimeters and pair A2009 with the primary procedure code for the wound application. Documentation should identify Symphony, the wound treated, the amount used, and the related procedure. CMS classifies A2009 as an add-on code: it is billed only with a primary procedure and paid within that procedure's global period. It is also a technical-component-only code, with interpretation represented by a separate code.

How to choose

- A2008 identifies Theragenesis, not Symphony. Select the code that matches the specific product supplied.
- A2010Wound matrixApis, per square centimeter
- A2010 identifies Apis. Its per-square-centimeter unit does not make it interchangeable with A2009.
- A2001Wound matrixAC, per square centimeter
- A2001 identifies Innovamatrix AC. A2009 is specific to Symphony, so the product documented determines the code.
A2009 billing questions
When should A2009 be selected instead of another wound matrix code?
Use A2009 when the product applied is Symphony. Other products have their own HCPCS codes, even when they are applied to a similar wound.
Can A2009 be billed by itself?
No. CMS identifies it as an add-on code that must be reported with a primary procedure.
How are units determined?
The code is measured per square centimeter. Document the quantity of Symphony used and report the corresponding units.
What procedure is reported with A2009?
Report the primary wound application procedure that matches the treated site and area. A2009 is paid within that procedure's global period.
Does A2009 include interpretation?
No. CMS classifies A2009 as technical-component-only; a separate code covers interpretation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
