What Q4223 covers

Q4223 identifies the Dermabind SL Optic product by the area supplied, rather than the clinician’s work applying it. It is used in ophthalmic care involving an ocular-surface defect, with an ophthalmologist typically selecting and placing the membrane in an office procedure room or outpatient surgical setting. The product code is distinct from the procedure that prepares or treats the ocular surface.

Report Q4223 only with a primary procedure; CMS treats it as an add-on paid within that procedure’s global period. Document the product name and the square-centimeter amount used, and report the application or reconstruction procedure separately. CMS classifies Q4223 as technical-component-only, with a separate code covering interpretation. The product’s quantity is based on its documented area, not the number of eyes or visits.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

65778Amniotic membrane
65778 reports the ocular-surface procedure using a self-retaining membrane. Q4223 identifies the Dermabind SL Optic product by area; it does not describe the procedure.
65779Amniotic membrane
65779 reports an ocular-surface procedure using a sutured membrane. Q4223 reports the Dermabind SL Optic product supplied, not the method of placement.
Q4222Wound matrix
Q4222 identifies Progenamatrix by area, while Q4223 identifies Dermabind SL Optic. Choose according to the product documented as supplied.
Q4224Wound matrix
Q4224 identifies HHF10-P by area. Q4223 is specific to Dermabind SL Optic, even though both descriptors use a square-centimeter unit.

Q4223 billing questions

Can Q4223 be billed by itself?

No. CMS identifies it as an add-on code, so report it with a primary procedure. Its payment falls within that procedure’s global period.

How should the units be determined?

Use the square-centimeter amount of Dermabind SL Optic supplied, supported by the product documentation and the clinical record.

Does Q4223 include the ocular procedure?

No. Q4223 identifies the product supply; report the applicable ocular-surface procedure separately.

Does this code include professional interpretation?

No. CMS classifies Q4223 as technical-component-only, with interpretation covered by a separate code.

How does Q4223 differ from Q4222 or Q4224?

Q4223 identifies Dermabind SL Optic. Q4222 and Q4224 identify different named products, so select the code matching the product actually supplied.
