FIELD GUIDE AHCCCS SUD billing and coding field guide carries the level-to-code map this issue keeps pointing back to. Open the field guide The SUD Operator · Issue #1 · July 2026

Your claims file is now your patient's eligibility file.

A Medicaid interim final rule effective July 31 makes a substance use disorder a mandatory exclusion from the new community engagement requirement, and tells states to prove it from adjudicated claims or encounter data in the preceding 12 months. Nothing older counts. On the payment side, CMS opened the first real conversation about ASAM Level 1.7 coding, extended behavioral telehealth into 2028, and reproposed the 40 percent CMHC rate factor. Four comment windows close between July 27 and September 14. Every item below carries the primary source we pulled it from.

This is Issue #1 of The SUD Operator as a dated issue. Every claim below traces to a Federal Register document we pulled and read this week, and each story ends with the link. Where we could not reach a source, we say so instead of writing around it. Arizona is the example: the AHCCCS site would not serve us during this sweep, so this issue reports no Arizona-specific change. The AHCCCS rules that were verified stay where they live, in the field guide.

Lead story · 01SUD is now a Medicaid exclusion, and your claims prove it or nobody does.

CMS published the community engagement interim final rule, file code CMS-2454-IFC, on June 3. It is effective July 31, 2026, comments are due July 31, 2026, and states must implement by January 1, 2027. The requirement is 80 hours per month of qualifying activities as a condition of eligibility for applicable individuals.

Here is the part that lands on a treatment program. At 42 CFR 435.554(c)(5)(i)(B), an individual with a substance use disorder is medically frail and therefore a specified excluded individual, with one carve-out: individuals in stable recovery, meaning five or more years in recovery. CMS states plainly that it interprets the exclusion to apply to individuals with an SUD regardless of whether they are in an active treatment program, and to include people in early recovery (under 12 months) and sustained recovery (1 to under 5 years). The condition must also significantly impair the person's ability to do the 80 hours.

Now the operational hinge. Under 42 CFR 435.557(f)(1), the state must first try to verify medical frailty ex parte, using reliable information it already holds, including adjudicated claims or encounter data from the preceding 12 months. And the rule is explicit that states may not consider information older than 12 months. CMS also tells states the data should span condition, service utilization (it names intensive outpatient and SUD services), and level of impairment.

The verification chain
Encounter posts, or the exclusion does not exist
Step 1 Step 2 Step 3 Step 4 Service delivered Claim adjudicated State ex parte check Exclusion granted inside 12 months claims or encounter no member burden Break step 2 and the member has to prove medical frailty by hand
Chain drawn from the verification requirements at 42 CFR 435.557(f)(1) in the interim final rule. It is a rule about data, and the data is your billing output.
What to do before Jul 31
  • Pull your SUD panel and age every member's most recent adjudicated claim or encounter. Anything with no paid or adjudicated line inside 12 months is a member whose exclusion your data cannot support.
  • Fix the unbilled and the denied first, not the aged AR. In this rule an unpaid claim and a claim that was never filed look identical: absent.
  • If you carry risk-based or grant-funded members whose services never generate an encounter, that population has no ex parte footprint at all. Flag it now and raise it with the plan.
  • Comments close July 31, 2026 at docket CMS-2026-2047. If relies on encounter data that lags a quarter, that is a comment worth filing.

12 mo

The whole exclusion runs on a 12-month claims window. States must attempt ex parte verification from adjudicated claims or encounter data in the preceding 12 months, and the rule bars them from considering anything older. Your billing lag is not a finance metric in 2027. It is the difference between a member keeping coverage automatically and a member being asked to document a substance use disorder in writing.

42 CFR 435.557(f)(1), interim final rule CMS-2454-IFC

Lead story · 02Residential and IMD days can carry the short-term hardship exception.

The same rule builds a second, narrower door. Section 1902(xx)(3)(B) creates an optional short-term hardship exception a state may adopt, and CMS implements it at 42 CFR 435.555. The first triggering circumstance is receipt of inpatient hospital, nursing facility, ICF/IID, or inpatient psychiatric hospital services, or other services of similar acuity as the Secretary determines appropriate.

CMS filled that phrase in. At 42 CFR 435.555(d)(1)(ii), other services of similar acuity include inpatient services furnished in an institution for mental diseases, inpatient services in a critical access hospital, inpatient services in an emergency hospital, and inpatient services furnished by other facilities the state recognizes even where Medicaid does not pay for them. CMS reasons that an individual who is an inpatient in an IMD is equally unable to meet the requirement. Inpatient is defined at 42 CFR 440.2 as room, board, and professional services for 24 hours or longer, or an expected stay of that length.

Two limits keep this honest. The exception is a state plan option, so it exists only where the state elects it, and the individual has to request it for the institutional circumstance. Note also that CMS is clear the medically frail exclusion comes first: if the state finds a person excluded at application or renewal, it does not go on to test community engagement or hardship at all.

What to do this quarter
  • Check whether has elected the short-term hardship option. If it has not, your residential census gets no protection from this door and everything rides on the medically frail exclusion.
  • Make sure residential and withdrawal-management days are documented to the 24-hour inpatient standard at 42 CFR 440.2, not just as program days.
  • Build the request into discharge planning where the state has elected the option. The member has to ask; nobody asks on their behalf by default.

Lead story · 03CMS finally asked the ASAM Level 1.7 question out loud.

The CY2027 Physician Fee Schedule proposed rule, published July 16, carries a section titled Bundled Payments Under the PFS for Substance Use Disorders, covering G2086, G2087, and G2088. Two things happen there.

First, a real rate movement. CMS proposes to revalue the Behavioral Health Care Manager clinical labor input from $0.57 to $0.70 per minute, a 22.8 percent increase, by crosswalking that role to the CORF social worker and psychologist labor category instead of genetic counselors. Because G2086 through G2088 carry that same labor input, CMS states the increase would apply to those codes as well. The same proposal lifts the collaborative care work RVUs: G2214 from 0.77 to 1.13, G0568 from 1.88 to 2.75, and G0569 from 2.05 to 2.26.

Second, a request for information that matters more than the rate. Interested parties told CMS that OTPs and non-OTP outpatient addiction settings both deliver ASAM Level 1.7 medically managed outpatient treatment, and that the only clinical difference is methadone. They pointed out that the bundle codes align with the new Level 1.5, and that there is no PFS coding at all for Level 1.7. CMS asks whether it should update the rates for G2086 through G2088 and whether additional coding is needed for Level 1.7. Comments are due September 14, 2026.

Proposed labor input
$0.57 to $0.70

Behavioral Health Care Manager (L057B) per minute. Flows to G2086, G2087, G2088 and the collaborative care codes.

Work RVU refinements
G2214 · G0568 · G0569

0.77 to 1.13, 1.88 to 2.75, and 2.05 to 2.26 respectively, aligned to the CPT 99492 and 99493 crosswalks.

Coding gap named
ASAM 1.7

Medically managed outpatient treatment including withdrawal management. No PFS code describes it today. CMS is asking.

If you run office-based addiction treatment outside an OTP, this is the one comment window in this issue that can change your unit economics rather than your paperwork. The ASAM level has always driven the code on the Medicaid side, which is the point of our ASAM levels to billing codes walkthrough. Medicare is now conceding the same logic has a hole in it.

What to do before Sep 14
  • Pull your last 12 months of G2086, G2087, and G2088 volume and model the labor revaluation. That is the size of the rate move you are commenting on.
  • If you deliver medically managed outpatient treatment with withdrawal management, write the comment. CMS asked a direct question about Level 1.7 coding and the record closes September 14, 2026.
  • Document what you already deliver at Level 1.7 in service-line terms. A comment with utilization behind it reads differently than a comment with an opinion behind it.

Source: CY2027 PFS proposed rule, 91 FR 43842, Federal Register, Jul 16, 2026

Payment policyBehavioral telehealth got another year, and two new modifiers.

The CY2027 PFS proposed rule restates where the statute now sits after the Consolidated Appropriations Act, 2026 (Pub. L. 119-75, February 3, 2026). Section 6209 moved four dates. Geographic restrictions, originating site expansion, and the expanded practitioner list run through December 31, 2027. The in-person visit requirement for mental health services furnished by telehealth is delayed to January 1, 2028. Audio-only telehealth is extended to January 1, 2028. RHC and FQHC telehealth payment flexibility runs through December 31, 2027.

The item nobody has calendared yet is section 6209(g). It requires new telehealth modifiers effective January 1, 2027, and CMS states it is creating modifiers BB and BC, with guidance to follow on the CMS website. They do not affect payment. They are required on claims for telehealth furnished through a virtual platform where the practitioner contracts with or has a payment arrangement with the platform owner, and on claims for telehealth furnished incident to a practitioner's professional service. A required modifier that does not change payment is exactly the kind of edit that silently rejects a quarter of your telehealth volume in January while everyone is watching the rate table.

What to do before Jan 1
  • Inventory every telehealth arrangement that runs through a third-party virtual platform. Those are the claims that need BB or BC from January 1, 2027.
  • Put a watch on CMS subregulatory guidance for BB and BC. Section 6209(h) lets the Secretary implement by program instruction, so the operating detail will not arrive in a rule.
  • Do not rewrite your in-person policy on the strength of a proposed rule. The dates are statutory, but confirm the implementing text in the final rule this fall.

Rate mechanicsThe CMHC per diem is still 40 percent of the hospital rate.

The CY2027 OPPS and ASC proposed rule, published July 7, keeps the PHP and IOP methodology finalized for CY2026. Hospital-based rates for APCs 5861, 5862, 5863, and 5864 are built from the geometric mean per diem cost using the broader OPPS data set and CY2025 OPPS claims, split between 3-service days and 4-or-more-service days. The four CMHC APCs, 5851 and 5852 for IOP and 5853 and 5854 for PHP, are then calculated at 40 percent of the corresponding hospital-based APC, the MPFS Relativity Adjuster CMS adopted in CY2026 to stop the cost inversion where 3-service day costs exceeded 4-service day costs.

The CMHC outlier math is unchanged for CY2027 as well: an outlier pays when a CMHC's cost exceeds 3.40 times the APC rate, at 50 percent of the excess, capped at 8 percent of that CMHC's total per diem payments for the year. Comments close August 31, 2026.

Two structural facts worth restating for SUD programs. PHP is defined in statute to cover acute conditions that expressly include substance use disorders, and the IOP benefit created by section 4124 of the CAA, 2023 is furnished by hospital outpatient departments, CMHCs, FQHCs, rural health clinics, and opioid treatment programs. If you run IOP in a CMHC, the 40 percent adjuster is the single largest number in your rate build, and it survived another rulemaking cycle.

What to do before Aug 31
  • Rebuild your CMHC IOP and PHP model as 0.4 times the hospital-based APC. If your budget still assumes a separately calculated CMHC cost basis, it is two rule cycles out of date.
  • Check your 3-service day rate. Days with three or fewer services pay the 3-service APC, so a program routinely delivering three services is not being paid a full day.
  • If your CMHC runs high-cost cases, model against the 3.40 times threshold and the 8 percent outlier cap before assuming outliers cover the tail.

The SUD Operator editorial desk

Deadline storySAMHSA wants to hand CCBHC oversight to accreditors. Comments close July 27.

On June 26, SAMHSA published a solicitation for public comment on developing an independent accreditation system for CCBHC Expansion grant recipients. The stated intent is to evaluate and approve independent accrediting bodies and transition certain CCBHC-E grant recipients from the current arrangement to independent accreditation, with a federal monitoring framework behind it. SAMHSA notes grantees may use program funding to cover accreditation costs rather than relying on self-attestation. Comments are accepted through 11:59 PM EST on July 27, 2026.

CCBHCs are required to deliver substance use disorder treatment, so this is a SUD governance question wearing a behavioral health label. Accreditation changes the cost of being a CCBHC, the cadence of your survey calendar, and the evidence burden on your clinical documentation. Two days is short, and a two-paragraph comment from an operator who runs the services counts.

What to do today
  • If you hold a CCBHC-E grant, file a comment before 11:59 PM EST on July 27, 2026. Say what an accreditation cycle costs you in staff hours, because that is the number the record is missing.
  • Whether or not you comment, start pricing accreditation into your FY27 CCBHC budget. SAMHSA has already said grant funds may be used for it.

FIELD GUIDE The AHCCCS SUD billing and coding field guide carries the ASAM level-to-code map, the modifier rules, and the auth paths that this issue keeps assuming you already have in place. Read it
Operator's move

Run a 12-month encounter-coverage report on your Medicaid SUD panel this week.

One report answers the only question this issue really asks: for how many of your members can the state find a paid or adjudicated SUD line in the last 12 months? Every member who fails that test is a member who will be asked to document medical frailty by hand starting January 1, 2027, and a member who may not answer the mail.

  1. Export your active Medicaid SUD roster and join it to the most recent adjudicated or paid claim line per member. Bucket by days since last adjudicated line: under 90, 90 to 180, 180 to 365, and over 365.
  2. Work the over-365 and the never-billed buckets first. In this rule those two look the same to the state, and both produce a member with no ex parte footprint.
  3. Separate the members whose services never generate an encounter at all, such as grant-funded or non-billable supports, and raise that population with the plan and the state before January.
  4. Then run the denial cut. A denied claim is not an adjudicated finding of a substance use disorder in any usable sense, so your denial backlog is now an eligibility backlog. Our SUD denial recovery case study is the version of this work with the numbers attached.

Operator Q&AThree questions operators are asking.

Our patients have an SUD diagnosis in the chart. Is that not enough for the exclusion?

Not by itself, and not in the way that matters. The rule requires the state to verify both the condition and that it significantly impairs the individual's ability to do 80 hours per month of qualifying activities, and it directs states to try that ex parte from adjudicated claims or encounter data in the preceding 12 months. A diagnosis in your chart that never reached the state as an adjudicated line is invisible to that check. The chart supports the appeal; the claim prevents the appeal.

A patient has been in recovery for six years. Are they excluded?

No, on that basis. The rule at 42 CFR 435.554(c)(5)(i)(B) excludes an individual with a substance use disorder but carves out individuals in stable recovery, defined as five or more years in recovery. CMS keeps early recovery (under 12 months) and sustained recovery (1 to under 5 years) inside the exclusion. A patient at six years would need to qualify on another basis, and this is exactly the population your reengagement and relapse-risk workflows should be watching in the back half of 2026.

Should we hold telehealth investment given the in-person requirement?

The in-person requirement for telehealth mental health services is delayed to January 1, 2028 and audio-only runs to the same date, both by statute in the Consolidated Appropriations Act, 2026. That is real runway. The nearer risk is administrative: modifiers BB and BC are required from January 1, 2027 on virtual-platform and incident-to telehealth claims, they do not change payment, and the operating guidance will arrive as program instruction rather than in a rule. Budget the build, not the retreat.

Educational only, and every rule cited here except the community engagement interim final rule is a proposed rule or a request for comment that can change before it is final. Verify each code, rate, modifier, and date against the final rule, live payer policy, and Medicaid agency at the point of submission. Where a source could not be reached, this issue says so rather than summarizing it.

How many of your members have no billable footprint?

Free SUD exposure check. Send a de-identified roster count and a slice of your claim and denial data. We return a written read on your 12-month encounter coverage, your never-billed and over-365 buckets, and the denial categories that are about to become eligibility problems. Yours to keep.

Common questionsFrequently asked: July's SUD policy wave.

Does a substance use disorder exempt someone from the new Medicaid community engagement requirement?
Yes, with one carve-out. The interim final rule at 42 CFR 435.554(c)(5)(i)(B) lists an individual with a substance use disorder as medically frail, and CMS states the exclusion applies whether or not the person is in an active treatment program. The rule excludes only individuals in stable recovery, which it defines as five or more years in recovery. The condition must also significantly impair the individual's ability to perform 80 hours per month of qualifying activities.
How do states verify that a patient has a substance use disorder for the exclusion?
Ex parte first. Under 42 CFR 435.557(f)(1) the state must attempt to verify medical frailty using reliable information already available to it, including adjudicated claims or encounter data from the preceding 12 months. The rule bars states from considering information older than 12 months. A claim that was never filed, never paid, or filed outside that window does not exist for this purpose.
When does the Medicaid community engagement rule take effect?
The interim final rule CMS-2454-IFC is effective July 31, 2026, and comments are due July 31, 2026 at docket CMS-2026-2047. States must implement the community engagement requirement by January 1, 2027.
Does residential SUD treatment count under the short-term hardship exception?
It can, at state option. CMS specifies at 42 CFR 435.555(d)(1)(ii) that other services of similar acuity include inpatient services furnished in an institution for mental diseases and inpatient services furnished by other facilities the state recognizes. Inpatient is defined at 42 CFR 440.2 as room, board, and professional services for 24 hours or longer. The short-term hardship exception is a state plan option, not a mandate, and the individual must request it.
What did CMS propose for the SUD bundled payment codes G2086 through G2088 in CY2027?
Two things. CMS proposes to revalue the Behavioral Health Care Manager clinical labor input from $0.57 to $0.70 per minute, which flows through to G2086, G2087, and G2088. Separately, CMS opened a request for information on whether to update the rates for those codes and whether new coding is needed to describe ASAM Level 1.7 medically managed outpatient treatment, which has no PFS code today. Comments on the CY2027 PFS proposed rule are due September 14, 2026.
What happens to behavioral telehealth flexibilities in 2027?
The Consolidated Appropriations Act, 2026 extended them. Geographic, originating site, and practitioner flexibilities run through December 31, 2027. The in-person visit requirement for telehealth mental health services is delayed to January 1, 2028, and audio-only telehealth is extended to January 1, 2028. RHC and FQHC telehealth payment flexibility runs through December 31, 2027. Two new telehealth modifiers, BB and BC, are required beginning January 1, 2027.
How are CMHC partial hospitalization and intensive outpatient rates calculated for CY2027?
CMS proposes to keep the 40 percent MPFS Relativity Adjuster. The four CMHC APCs, 5851 and 5852 for IOP and 5853 and 5854 for PHP, are set at 40 percent of the corresponding hospital-based APCs 5861, 5862, 5863, and 5864. Hospital-based rates are built from CY2025 OPPS claims and geometric mean per diem cost for 3-service days and 4-or-more-service days. Comments on the CY2027 OPPS proposed rule are due August 31, 2026.

That is Issue #1. Issue #2 lands in August with the AHCCCS sweep we owe you once the site is reachable, the CY2027 OPPS comment recap, and the first state responses to the community engagement implementation deadline.
