About Q4237: Cryopreserved umbilical cord tissue supply
Reports Cryo-Cord umbilical cord tissue supplied for wound treatment, measured by square centimeter and paired with the applicable skin-substitute application procedure.
Q4237 identifies Cryo-Cord, an umbilical-cord-derived tissue product used as a wound covering. The code represents the product supplied, not the clinician’s work applying it. It may be used in wound-care settings where a skin substitute is placed over a wound; the clinician performing the application and the practice furnishing the product should document the product used and the treated wound area.
Report Q4237 by square centimeter and only with a primary procedure, such as the applicable skin-substitute application code. The record should identify Cryo-Cord, the wound site and dimensions, the application performed, and the product area represented by the billed units. CMS classifies Q4237 as an add-on code paid within the primary procedure’s global period, so it is not reported by itself. CMS also identifies it as technical-component-only; interpretation is covered by a separate code.

Q4237 billing questions
When should Q4237 be selected instead of another skin substitute product code?
Use Q4237 when the product furnished is Cryo-Cord. Other product codes identify different products, even when they are measured by the same unit.
Can Q4237 be reported without an application procedure?
No. CMS classifies Q4237 as an add-on code that must be billed with a primary procedure.
How are Q4237 units counted?
The code is measured per square centimeter. Document the Cryo-Cord area represented by the units billed.
What documentation supports Q4237?
Record the product identity, wound location and dimensions, application procedure, and area of product used or represented on the claim.
Does Q4237 include interpretation?
CMS identifies Q4237 as technical-component-only and states that a separate code covers interpretation.
How does the global-period rule affect Q4237?
CMS pays this add-on within the primary procedure’s global period. Report it with the primary procedure rather than as a standalone service.
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.
