What Q4220 covers
Q4220 represents the supplied Bellacell HD or SureDerm product, rather than the clinician’s work applying it. These products may be used in wound care, including in outpatient wound clinics and surgical or podiatric practices. The clinician separately performs and reports the appropriate application procedure; the product code identifies the specific material supplied for that treatment.
Report the product in square-centimeter units based on the amount used, and pair it with a qualifying primary application procedure. Keep documentation that identifies Bellacell HD or SureDerm and supports the quantity supplied and applied. CMS classifies Q4220 as an add-on: it is not billed alone, and payment falls within the primary procedure’s global period. It is a technical-component-only code; a separate applicable code covers interpretation.

Q4220 billing questions
Can Q4220 be billed by itself?
No. CMS identifies it as an add-on, so report it with the primary wound application procedure.
How should units be determined?
Use square-centimeter units for the Bellacell HD or SureDerm product supplied and applied. The record should support the product identity and quantity.
Is the application procedure included in Q4220?
No. Q4220 identifies the product; report the appropriate application procedure separately as the primary service.
Does Q4220 include a professional interpretation component?
No. CMS classifies Q4220 as technical-component-only, with interpretation covered by a separate applicable code.
Should Q4220 be reported instead of Q4221?
Select the HCPCS code that matches the product actually supplied. Q4221 identifies a different product, Amniowrap2, and is not selected based only on wound size.

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.
