About Q4398: Summit AC skin-substitute product
Q4398 reports Summit AC skin-substitute material by square centimeter when supplied with a primary wound procedure that applies the product.
Q4398 identifies Summit AC, a skin-substitute product reported by the square centimeter. It represents the product material used in wound care, not the wound-preparation or application work itself. It is reported when a clinician applies Summit AC during a primary wound procedure, such as in an office or hospital outpatient setting. The record should identify the product and the wound treated.
Report Q4398 only with a primary procedure; it is an add-on, not a stand-alone service. Units follow the square-centimeter measure reported, so documentation should support the amount applied and link it to the wound and application encounter. CMS classifies this as a technical-component-only code, with interpretation covered by a separate code. Payment falls within the primary procedure’s global period. Keep Summit AC distinct from other Summit formulations and other separately coded skin-substitute products, even when they are used for similar wound-care needs.

Q4398 billing questions
Can Q4398 be billed by itself?
No. CMS identifies Q4398 as an add-on code that must be billed with a primary procedure.
How should units be supported?
Document the Summit AC product used and the square-centimeter amount applied to the wound during the primary procedure.
Does Q4398 include interpretation?
No. CMS classifies it as technical-component-only; a separate code covers interpretation.
How does the primary procedure affect payment?
Q4398 is paid within the primary procedure’s global period, rather than as a separate service outside that period.
Should Q4398 be used for another Summit product?
Use Q4398 for Summit AC specifically. Summit AAA and Summit FX have distinct codes, Q4397 and Q4399.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
