Montana policy summary. Montana has a materially updated 2026 physician-level reimbursement baseline for RPM, CCM and TCM, but the July transition creates a publication-status nuance that must remain visible to planners. DPHHS's June 30, 2026 provider notice says the July 1 fee schedules are used to reimburse providers beginning July 1 and reflect 2026 RBRVS RVUs plus statutory physician-services rate adjustments. As rechecked September 28, the current Physician provider page still lists January 2026 as its latest formally posted Physician Services schedule, while the July 2026 Physician Services files remain on the proposed-fee-schedule page. Because DPHHS identifies the July schedules as the operational reimbursement basis even though the provider-type page has not completed the formal publication handoff, this page does not present January dollar amounts as current planning values. Montana's published telemedicine policy supports reimbursement for covered services delivered through telemedicine or telehealth when medically necessary, clinically appropriate, consistent with the applicable provider manual, and not specifically required to be face-to-face; payment follows the applicable service rate. That coverage principle does not by itself prove payment of every Medicare RPM, CCM or TCM code. The August 21 PCMT notice adds an operational safeguard: the old Passport referral-ID requirement is removed for dates of service after June 30, 2026, but provider-specific rules for medical orders, referrals and prior authorization still apply. The September 14 temporary retroactive PMPM enrollment deadline has passed, so later qualified PCMT enrollment follows the normal payment methodology rather than the temporary July/August retroactive pathway. DPHHS's Medicaid-changes page, current through September 21, adds a separate October 1 collectibility checkpoint: certain noncitizen eligibility categories change and Medicaid Expansion applications routed through the Federally Facilitated Marketplace receive Montana community-engagement verification. These are eligibility controls, not RPM/CCM/TCM benefit expansions or reductions. Before billing or revenue modeling, verify the exact date-of-service code and amount in the current DPHHS file or with Montana Provider Relations, plus active member eligibility, payer assignment, provider participation, scope, medical necessity, modifiers or place of service, frequency, documentation, medical-order, referral, prior-authorization and PCMT enrollment requirements. Treat the legacy Montana workbook as planning material only when consistent with current Montana Healthcare Programs policy and the latest controlling fee schedule.
Freshness window: recheck the official source by October 1, 2026, or sooner after a material payer change. Effective/source context: Montana DPHHS continues to use the July 1, 2026 fee schedules as the reimbursement basis beginning July 1, 2026, reflecting 2026 RBRVS RVUs and statutory physician-services rate adjustments. As rechecked September 28, 2026, the Physician provider page still lists January 2026 as its latest formally posted Physician Services schedule while the July 2026 Physician Services files remain on the proposed-fee-schedule page pending the formal publication handoff. Current provider guidance confirms that the Primary Care Montana transition removed the former Passport referral-ID requirement for service dates after June 30, 2026 but did not remove provider-specific medical-order, referral, or prior-authorization requirements. Montana DPHHS also updated its Medicaid-changes guidance through September 21, 2026 and identifies October 1, 2026 as a state-specific eligibility transition date for certain noncitizen categories and for community-engagement review of Medicaid Expansion applications routed through the Federally Facilitated Marketplace. Those eligibility changes are separate from RPM, CCM, or TCM coverage policy and require date-of-service eligibility verification before revenue is treated as collectible.

October 1 Montana eligibility checkpoint — not a coverage expansion
Re-verify Montana Medicaid eligibility and payer assignment for October dates of service
Montana DPHHS says its Medicaid-changes guidance is current as of September 21, 2026. Beginning October 1, the July-through-September community-engagement hold-harmless period ends, and certain qualified noncitizen categories are affected by the federal eligibility transition, and Medicaid Expansion applications coming through the Federally Facilitated Marketplace are subject to Montana community-engagement verification by DPHHS. These changes do not establish or remove RPM, CCM, or TCM coverage. For October dates of service, verify active eligibility, delivery system, payer assignment, provider participation, authorization, and the applicable date-of-service fee schedule before treating expected Medicaid revenue as collectible.

October 1, 2026 eligibility transition: verify the member on the date of service
Federal Medicaid and CHIP matching rules change for certain noncitizen eligibility categories beginning October 1, 2026. CMS instructed states to redetermine potentially affected current beneficiaries by that date. State implementation and any state-funded coverage pathways can differ, so this notice does not replace Montana eligibility guidance. For RPM, CCM, and TCM collectibility, re-check the member's active eligibility, payer, delivery system, and managed-care assignment for the actual date of service rather than carrying a pre-transition result forward.
October 1, 2026 coding and claim-edit transition: use date-of-service rules
CMS has released FY 2027 ICD-10-CM codes for patient encounters from October 1, 2026 through September 30, 2027, plus the October 2026 HCPCS quarterly file, which CMS updated September 23, 2026. RPM, CCM, and TCM are billed with CPT/HCPCS service codes, but diagnosis coding and effective-dated HCPCS changes can affect medical-necessity edits, authorization, claim routing, risk adjustment, and claim acceptance. For dates of service on or after October 1, use the diagnosis and HCPCS sets applicable to that date and check Montana Medicaid and the member's managed-care plan for any separate claims-system or companion-guide instructions.
CMS has also posted Medicare and Medicaid National Correct Coding Initiative updates effective October 1, 2026, with Q4 change files posted September 1, 2026 and Medicare practitioner and hospital PTP production files posted September 2. The October releases include procedure-to-procedure edits, medically unlikely edits, and Medicare add-on-code edits. Do not infer that an RPM, CCM, or TCM code became covered, noncovered, payable, or denied merely because it appears in an NCCI file; evaluate the exact code pair, units, modifier indicator, payer, provider, and date of service. CMS expressly notes that a code's presence in a Medicaid NCCI edit does not establish coverage by a state Medicaid program.
What to verify in Montana
Build the reimbursement picture in layers
Medicare baseline
Confirm the applicable physician fee schedule, MAC/locality, clinician QP or non-QP status, code descriptors, supervision rules, device/data requirements, time thresholds, and any annual coding changes.
Montana Medicaid program
Review the current fee schedule, provider manual, telehealth or remote-monitoring guidance, eligible provider types, places of service, and billing limitations.
Managed care
Do not assume state-level policy equals MCO payment. Verify plan contracts, prior authorization, care-management benefits, alternative payment methods, and value-based arrangements separately.
Claims lifecycle
Check timely-filing, clean-claim, corrected-claim, reconsideration, appeal, recoupment, and payer-specific denial-recovery windows before treating an otherwise covered service as collectible.
Eligibility & coordination
Verify member eligibility and plan assignment for the date of service, then confirm Medicare, commercial insurance, other third-party liability, crossover, and payer-of-last-resort rules when they apply.
Revenue model
Model payer mix, eligible patient volume, realistic utilization, staffing, device/platform expense, contract-specific reimbursement, denial leakage, and realistic collection timing only after the policy and claims assumptions are verified.
Verified Medicare baseline
CY 2026 national policy, checked
CMS finalized CY 2026 Physician Fee Schedule policy effective January 1, 2026. CMS currently describes Medicare RPM as connected-device monitoring for acute or chronic conditions, with digitally uploaded physiologic data and program-specific service requirements. CMS's current fraud-prevention guidance tells providers to furnish all three main RPM components — education/setup, device supply, and treatment management — rather than treating an isolated setup event as a complete monitoring program. The 2026 RPM code set added CPT 99445 and 99470 for lower-day and lower-time monitoring scenarios. CMS's current Medicare RPM guidance also says an ordering physician or other qualified health care provider is not required for RPM services and ordering-provider information is not required on the Medicare claim; do not carry that Medicare claim-field rule into Montana Medicaid, an MCO, or an internal clinical protocol without confirming that payer's own ordering, referral, enrollment, and documentation requirements.
This Medicare baseline is national. It does not establish Montana Medicaid or MCO coverage, payment, provider eligibility, or billing rules.
September 2026 CMS billing-risk signal
Apply claim-integrity checks before projecting RPM revenue
CMS's Healthcare Fraud Prevention Partnership September 2026 analysis reviewed high-risk RPM/RTM outliers from January 2025 through May 2026 and flagged patterns involving excessive frequency, initial setup without subsequent monitoring, and services billed during inpatient or skilled-nursing-facility stays. These are program-integrity risk signals, not new Montana coverage rules. Use them as workflow controls, then apply the state and plan-specific rules above.
CMS HFPP September 2026 RPM/RTM analysis →Quarterly PFS timing safeguard
For a date of service of October 15, 2026, the applicable 2026 Medicare release is October 2026 (RVU26D / PFREV26D). Use the PFS release applicable to the actual date of service, not simply the newest file CMS has posted.
2027 Medicare policy watch · proposal only
Do not apply proposed CY 2027 RPM rules to 2026 dates of service
CMS's CY 2027 Physician Fee Schedule proposed rule would change remote-monitoring operations if finalized, including a separately reportable initiating visit when RPM or RTM begins, an established-patient requirement for RTM, and limits on payment when clinical-staff monitoring work is performed by contractors rather than staff employed by the billing practice. CMS also proposed valuation changes and sought comment on a possible future four-G-code bundled structure. The public comment period closed September 14, 2026; these provisions remain proposals unless CMS adopts them in a final rule. For current Montana planning, keep using CY 2026 Medicare requirements plus the state and plan rules above for the actual date of service.
Code families
RPM, CCM, and TCM planning reference
These code families identify the services that should be checked against current Medicare and Montana Medicaid rules. Inclusion here does not mean every code is payable by every payer or provider type.
Remote Patient Monitoring
99453 · 99454 · 99445 · 99457 · 99458 · 99470 · 99091
Verify device eligibility, data collection/transmission requirements, treatment-management time, interactive communication, supervision, and billing frequency. For 2026 Medicare planning, 99445 covers the 2-15-day device-supply tier and should not be reported with 99454 for the same monitoring period; verify payer-specific adoption before applying that rule to Medicaid or an MCO.
Chronic Care Management
99490 · 99439 · 99491 · 99437 · 99487 · 99489 · G0506
Verify patient eligibility, initiating-visit and comprehensive care-plan requirements, qualifying clinical staff time, complexity, add-on logic, consent, and overlapping-service rules. Medicare may allow HCPCS G0506 once with a qualifying initiating visit when the billing practitioner personally performs extensive assessment and care planning beyond the usual initiating-visit work; do not assume the same pathway applies to Medicaid or an MCO.
Transitional Care Management
99495 · 99496
Verify discharge eligibility, interactive contact timing, medical decision-making level, face-to-face visit timing, and payer-specific post-discharge requirements.
