Indiana runs four separate Medicaid brands, lets one insurer act as both a commercial carrier and a Medicaid plan, and routes Medicare through a contractor most billing teams have never dealt with before. A practice that treats Indiana like a generic Midwest state loses money it never sees leave.
Most billing teams learn Medicaid once and reuse that knowledge everywhere. Indiana breaks that habit. The Healthy Indiana Plan, Hoosier Healthwise, Hoosier Care Connect, and PathWays for Aging are administered as four distinct programs, each with its own eligibility rules and its own mix of managed care entities.
Layer in a commercial market where the largest insurer is also the largest Medicaid plan, plus a Medicare contractor that only two states share, and a claim that looks routine anywhere else can still bounce here. Understanding why it bounced, not just resubmitting it, is most of the job.
Every claim a practice sends in Indiana lands in one of three systems, and each one plays by its own logic.
Four Medicaid programs, five plans between them. Hoosier Healthwise covers children and pregnant women, HIP covers working-age adults through a Section 1115 waiver approved through 2030, Hoosier Care Connect covers non-elderly adults with disabilities, and PathWays for Aging (launched July 1, 2024) covers members 60 and older with long-term service needs. Anthem is contracted across all four. CareSource and Managed Health Services (MHS) serve HIP and Hoosier Healthwise. Humana and UnitedHealthcare serve PathWays. Dental runs through a separate carve-out with DentaQuest and MCNA.
One insurer wearing two different hats. Elevance Health, headquartered in Indianapolis, operates Anthem as both a major commercial carrier and the broadest Medicaid MCE in the state. Anthem's commercial claims and Anthem's Medicaid claims are reviewed under different medical necessity criteria and different fee schedules. Billing them as if they're the same payer is how avoidable denials happen.
Medicare that doesn't run through a neighbor. Part A and Part B claims in Indiana are processed by WPS Government Health Administrators, the Jurisdiction 8 contractor shared only with Michigan. WPS handles roughly 1.56 million fee-for-service beneficiaries and close to 60,000 physicians, with its own local coverage determinations. A billing team used to a different MAC's edits is working from the wrong playbook.
None of this happens against a comfortable backdrop. RAND's most recent hospital price study ranked Indiana eighth highest in the nation for hospital prices, with employers and insurers paying 297 percent of Medicare rates against a national average of 254 percent. The flip side, according to the Indiana Hospital Association, is that Indiana's base Medicaid reimbursement rate sits at just 57 percent of what a non-Medicaid patient's care is billed at, the eighth-lowest rate in the country and one that hasn't moved in three decades. Lawmakers are now pressing back on the hospital side: House Enrolled Act 1004 requires the state's five largest nonprofit systems (Ascension St. Vincent, Community Health Network, Franciscan Health, IU Health, and Parkview Health) to offer direct-to-employer contracts at or below 260 percent of Medicare, a requirement all five met for 2025, with Ascension St. Vincent coming in lowest at 171 percent. Standalone hospitals face the same requirement starting September 1, 2026, and a statewide pricing benchmark tied to nonprofit tax status takes effect in 2029. For an independent physician practice sitting between high hospital prices and low professional fees, every uncollected dollar counts more here than in most states.
FSSA ended MDwise's participation in HIP and Hoosier Healthwise on January 1, 2026, citing cost and quality performance below its remaining plans. Affected members were reassigned to Anthem, CareSource, or MHS, prior authorizations only carry over for 90 days, and the nonemergency transportation broker for those members switched to WellTrans. A claim billed against a lapsed MDwise authorization reads like a clinical denial when it's really an administrative one.
HIP Plus and HIP Basic carry different cost-sharing rules under the POWER account structure that's unique to Indiana's waiver. Verifying that a patient has HIP without confirming the tier is how patient-responsibility errors show up as bad debt months later.
Since July 1, 2025, Indiana law bars private, fully-insured commercial plans from requiring prior authorization for the first 12 physical therapy or chiropractic visits of a new episode of care. It exempts Medicaid and state employee health plans entirely, and visit 13 still needs the same authorization it always did. Applying the exemption to the wrong plan type is the new way to get a PT claim denied.
IHCP Bulletin BT202510 tells providers not to use the GT modifier at all: telehealth claims need place-of-service code 02 or 10 with modifier 93 for audio-only or 95 for audio-video. Behavioral health claims billed under a supervising practitioner also switched from modifiers AH, AJ, or HF to modifier HE as of January 1, 2025. Old habits from Medicare billing don't transfer.
Indiana capped ABA lifetime coverage at 4,000 hours and moved to Early and Periodic Screening, Diagnostic and Treatment (EPSDT) eligibility, meaning coverage for members 21 and older phases out between April 1 and September 30, 2026. New ABA agency enrollment has been frozen since June 6, 2026 under a CMS-approved moratorium, and existing agencies now need formal accreditation. A practice that isn't tracking a client's remaining hours and enrollment status against these dates is billing into a wall.
Under IHCP Bulletin BT202647 and Senate Enrolled Act 222, home health agencies must be enrolled and recognized as Medicare providers by July 1, 2026, or show proof of a submitted application before April 1, 2026, with full completion required by June 30, 2027. Miss the window and IHCP reimbursement stops.
The eligibility change coming in 2027. Starting January 1, 2027, HIP members ages 19 to 64 must complete 80 hours a month of qualifying work, schooling, or volunteering, or show at least $580 in monthly income, verified on a three-month lookback. Anyone applying in January 2027 must already show compliance for October through December 2026. Indiana also resets Medicaid income limits every March 1, not January 1 like most states, a detail that trips up front-desk eligibility checks year after year.
As of January 2025, 71 of Indiana's 92 counties carried a federal primary care health professional shortage designation, and HRSA had 169 separate primary care shortage areas mapped across the state by the end of 2025. Hospitals aren't insulated either: the Indiana Hospital Association's January 2026 analysis put the median hospital operating margin at 1.9 percent against a 2.6 percent national median, with more than $717 million in 2025 care left unpaid because of denials and delayed insurer payments, part of a statewide backlog the association puts above $1.6 billion. Independent practices are absorbing all of this with the same one or two staff members who also answer phones and room patients.
We support healthcare practices across Indiana remotely. Because our team is based in Michigan, we already bill into the same WPS Jurisdiction 8 territory Indiana Part B providers use, so its local coverage determinations, portal quirks, and edit logic are part of our daily workflow, not a state we had to learn from scratch.
| Indiana pressure point | What we do about it |
|---|---|
| Post-MDwise reassignment | Re-verify MCE assignment and prior authorization status before the 90-day carryover window closes, and confirm which transportation broker now applies. |
| HIP Plus vs. HIP Basic | Capture the plan tier at scheduling, not at the point of denial, so patient responsibility is calculated correctly from the first bill. |
| SB 480 routing | Flag payer type (fully-insured commercial vs. Medicaid vs. state employee plan) before deciding whether a PT or chiropractic visit needs authorization at all. |
| Telehealth modifier rules | Modifier 93/95 and place-of-service logic built into claim scrubbing before submission, with GT blocked outright. |
| ABA hour caps and accreditation | Hours-remaining and EPSDT age checks run against every claim before it goes out, alongside current agency accreditation status. |
| Home health Medicare enrollment | Enrollment status tracked against the July 2026 and June 2027 deadlines so IHCP billing doesn't lapse without warning. |
The most heavily scrutinized category in the state right now. Coverage is moving to an EPSDT-only, under-21 model with a 4,000-hour lifetime cap, new agency enrollment is frozen, and accreditation is now required. Session documentation has to match exactly what was authorized.
Direct beneficiaries of SB 480's prior authorization exemption, but only for fully-insured commercial plans. Medicaid and state employee plans are excluded outright, and visit-count tracking still matters past the twelfth visit.
INSPECT PDMP compliance has to be documented alongside the E/M and procedural codes it supports, not filed as a separate afterthought.
Exposed to WPS Jurisdiction 8's local coverage determinations on high-dollar procedures, where a missing supporting diagnosis code can drop reimbursement for the whole claim.
The specialties most exposed to Indiana's low Medicaid and commercial physician rates. Complete chronic care and preventive care capture is what keeps these practices viable at Indiana's fee levels.
Has to correctly distinguish HIP Basic cost-sharing at the point of service rather than writing off the difference later, and increasingly sees telehealth-adjacent billing questions from patients routed there after hours.
Denials are prevented at the front end far more often than they're won on appeal. Every stage below is built around Indiana's specific payer rules, not a generic template.
Hiring and keeping billing staff who already understand four Medicaid programs, a dual-hat commercial carrier, and a shared Medicare jurisdiction is difficult almost anywhere in Indiana, and harder still with 71 of 92 counties designated primary care shortage areas.
The state's own rural health strategy acknowledges the strain: Indiana received $206.9 million in year one of its five-year, federally funded Rural Health Transformation Program, with $120 million of that going toward regional GROW grants meant to stabilize rural care access. That funding exists because 52 rural Indiana hospitals are already operating on thin margins, and roughly a quarter of them have already cut services.
Against a backdrop where the Indiana Hospital Association estimates over $1.6 billion in unpaid claims are sitting in the system statewide, a practice that outsources its billing to a team already fluent in these specific rules is closing a gap most others are still trying to name.
It depends on age and eligibility category: Hoosier Healthwise for children and pregnant women, HIP for working-age adults, Hoosier Care Connect for non-elderly adults with disabilities, or PathWays for Aging for members 60 and older. Each has its own MCE roster, so the program name alone doesn't tell you which plan to bill.
MDwise exited HIP and Hoosier Healthwise entirely on January 1, 2026. The patient was reassigned to Anthem, CareSource, or MHS, and any prior authorization from MDwise is only honored for 90 days under the new plan. Re-verify both the MCE and the authorization status before billing the next visit.
Only for the first 12 visits of a new episode of care, and only under fully-insured commercial plans. Medicaid and state employee health plans are specifically excluded from the law, so those authorizations still apply from visit one.
No. IHCP has explicitly instructed providers not to use the GT modifier. Claims need place-of-service code 02 or 10 paired with modifier 93 for audio-only visits or 95 for audio-video visits.
Start tracking eligibility documentation now. The requirement phases in January 1, 2027, but applicants for that month must already show three months of qualifying activity going back to October 2026. Front-desk eligibility verification is about to carry more weight than it has in years.
We're based in Michigan, which puts us inside the same WPS Jurisdiction 8 Medicare territory Indiana practices already bill into, so the Medicare side of your claims runs through a system our team works in every day.
If claims are aging past the payer's actual deadline, if a tier mix-up is quietly writing off patient balances, or if your team is still applying old telehealth modifiers, the revenue is already gone before anyone notices. A short review of your last quarter of denials usually shows exactly where it's happening.
