ASC Billing Services · CY2026

The case is on the list. Does the facility fee actually cover the implant?

Two different questions decide whether an ASC case pays. First: is the procedure on the CMS ASC Covered Procedures List? Second: is it device-intensive? Schedulers who only check the first one keep booking cases that lose money on the hardware.

Short answer: A procedure earns an ASC facility fee only when it sits on the ASC-CPL (Addendum AA). Whether that fee covers a costly implant depends on device-intensive status, which CMS assigns when the device offset exceeds 30% of the procedure cost. On, but not device-intensive, means the standard packaged rate. On, and device-intensive, means the device portion is paid at the full hospital rate.

The decision your scheduler runs

Two yes-or-no questions, four very different outcomes

Do not treat covered and device-intensive as one status. Map every high-cost case against both axes before it hits the schedule. The gold quadrant is where an ASC actually clears the economics of an implant-heavy case.

Device-intensive
(offset > 30%)

Not device-intensive

On the ASC-CPL

Book it

Covered + device-intensive

The site gets the ASC facility payment and the device portion is paid at the full hospital (HOPD) device rate, so the implant does not sink the margin.

ASC PI J8 · fee = service portion + HOPD-rate device

Book, check margin

Covered, standard rate

Payable in the ASC at the standard packaged rate. Any low-cost supplies are bundled. Fine for labor-driven cases, tight for anything with real hardware.

Standard ASC rate · device packaged, not carved out

Not on the ASC-CPL

Redirect

Device-intensive, not covered

Device-intensive status means nothing if the code is not on Addendum AA. No ASC facility fee. Route to the hospital outpatient department.

Addendum EE / excluded · $0 ASC facility

Redirect

Neither

Excluded from ASC payment, often for clinical or overnight-stay reasons under the five general standards. Site of service is the hospital.

Addendum EE · not payable in ASC

Worked examples

Same list, different money: reading the two columns together

Illustrative codes showing how the two statuses diverge. Always confirm the covered flag on the CY2026 Addendum AA and the offset percentage on Addendum P for your exact date of service before you commit the case.

CPT	Procedure archetype	On ASC-CPL (Add. AA)	Device-intensive (Add. P, >30%)	ASC PI	What the facility fee covers
63685	Implant spinal neurostimulator pulse generator	Yes	Yes	J8	Service + generator paid at HOPD device rate
64590	Implant peripheral neurostimulator generator	Yes	Yes	J8	Device carved out, not buried in a flat rate
33285	Insert subcutaneous cardiac rhythm monitor	Yes	Yes	J8	Monitor cost recovered at hospital device rate
66984	Cataract removal with IOL insertion	Yes	No	Std	Standard ASC rate; IOL packaged, high volume carries it
29827	Arthroscopic rotator cuff repair	Yes	No	Std	Labor-driven; standard rate works, low implant cost
Add. EE	Procedure excluded under the five general standards	No	n/a	Excl	No ASC facility payment; redirect to HOPD

Why device-intensive changes the math

The offset percentage is the whole story

A device-intensive procedure

When the device offset is above 30%, CMS splits the payment. The hardware is reimbursed at the full hospital device amount, so an ASC is not eating the implant out of a single packaged rate.

Device portion (HOPD rate)>60%

Service portion (ASC rate)~40%

A non device-intensive procedure

Below the threshold, the supply is packaged into one standard ASC rate. Perfectly workable for labor-heavy cases, but a real exposure the moment the hardware cost climbs past what the flat rate assumes.

Offset below the line<30%

The default 31% offset CMS assigns to brand-new device codes with no claims history is what pushes many freshly added procedures over the line in their first year on the list.

Do this every rule cycle

The four-step verification a scheduler should never skip

Confirm covered status

Match the CPT against the CY2026 covered list. If it is not there, it is not an ASC facility case, full stop.

CMS ASC-CPL · Addendum AA

Check device-intensive

Pull the offset percentage. Above 30% means the implant is carved out and the case can carry its own hardware.

Addendum P · offset %

Read the payment indicator

PI J8 confirms device-intensive handling. A standard indicator tells you the supply is packaged into one rate.

Rule out exclusions

Screen against the excluded list so a redirect happens before scheduling, not after a denied facility claim.

Where these rules actually live

CY2026 OPPS/ASC Final Rule (CMS-1834)Sets ASC payment rates and covered-procedure policy for services January 1 through December 31, 2026.

CMS ASC Covered Procedures ListAddendum AA lists covered surgical procedures; Addendum BB covers ancillary services paid in the ASC.

Device-Intensive Procedures (Addendum P)Publishes the device offset percentage per code; above 30% triggers device-intensive payment handling.

ASC Excluded Procedures (Addendum EE)Procedures CMS excludes from ASC payment, often under the five general clinical-safety standards.

The specific codes CMS adds or removes shift with each annual rule. Treat the examples above as a reading method, not a substitute for pulling the current CY2026 addenda for your date of service. Booking off a stale list is one of the most common preventable ASC facility denials.

Stop scheduling implant cases that lose money on the hardware

ASP-RCM builds the covered-plus-device-intensive check straight into scheduling and charge capture, so every ASC case is screened against the current CY2026 addenda before it is booked, coded, and billed. Fewer redirects, cleaner facility claims, hardware that actually gets paid.
