Automatic Insurance Downcoding: What NPs and Other Providers Need to Know—and Where States Are Fighting Back
Updated September 24, 2026
You submit a claim for a 99214. The insurer’s software decides the visit should have been a 99213, changes the code, and pays the lower amount—without requesting the medical record or having a clinician review the documentation. If you disagree, the burden falls on your practice to identify the altered claim, retrieve the record, prepare an appeal, and wait for the insurer to decide whether it will pay for the level of care originally provided.
That is automatic insurance downcoding, and healthcare providers across the country are reporting that it is becoming increasingly common.
The good news is that states are beginning to respond. As of September 24, 2026, 15 states have identifiable movement involving insurance downcoding. Some have enacted protections, some have pending legislation, and others now have previous bills that provide a foundation for renewed advocacy in 2027.
What is automatic downcoding?
Downcoding occurs when an insurer or claims administrator unilaterally replaces a healthcare service code submitted by a provider with a lower-level or lower-paying code.
The current controversy is not about whether insurers may investigate inaccurate coding, fraud, or improper billing. Insurers can request documentation, review records, deny unsupported claims, and conduct appropriate audits.
The concern is the sequence:
The provider submits a claim based on the service performed and the documentation in the medical record.
An algorithm or claims-editing system changes the code without reviewing that record.
The insurer pays the lower amount.
The provider must then appeal and submit documentation to prove entitlement to the original reimbursement.
In other words, the insurer reduces payment first and reviews the clinical evidence later—if the provider notices and has the time and resources to appeal.
Why this matters to NPs and independent practices
A difference of $30 or $50 on one claim may not seem catastrophic. Repeated across hundreds of visits, however, automatic downcoding can create substantial losses.
It also creates costs beyond the reduced reimbursement:
Staff time spent comparing claims and remittances
Time retrieving records and preparing appeals
Billing-company or consultant fees
Delayed payment
Interest and financing costs
Increased administrative burden
Distorted coding and utilization data
Pressure to avoid treating high-acuity or medically complex patients
Pressure to bill lower-level codes defensively
Small and independent practices are particularly vulnerable because they do not have large revenue-cycle departments devoted to identifying and appealing altered claims.
The national landscape
The states with direct movement currently fall into three categories:
States with enacted laws or regulatory protections
States with active bills or organized pre-legislative initiatives
States where bills did not pass but can provide a starting point for 2027
States with enacted laws or regulatory protections
Maryland: Proactive unilateral downcoding is prohibited
Maryland currently has the strongest immediate position.
In April 2026, the Maryland Insurance Administration issued Bulletin 26-9, stating that downcoding is not permitted under §15-1005 of the Maryland Insurance Article. The bulletin explains that a payer may pay the claim or issue a denial or partial denial, explain the reason, and request additional information.
A payer may not simply replace the submitted service code with a lower code, pay the reduced amount, and require the provider to prove entitlement to the original code afterward.
Maryland also considered SB 797/HB 1153 in 2026, which would have created more explicit downcoding procedures, but those bills did not pass. The failure of the bills does not eliminate the Insurance Administration’s existing interpretation of current law.
What Maryland providers can do: Review remittances for substituted codes. If a state-regulated payer proactively modifies a submitted code, cite MIA Bulletin 26-9 and Insurance Article §15-1005 in the appeal and report recurring patterns to the Maryland Insurance Administration.
Indiana: AI cannot be the sole basis without record review
Indiana enacted HEA 1271, also known as Public Law 88. Its downcoding provisions became effective July 1, 2026.
The law prohibits an insurer from using an automated process, system, or tool—including artificial intelligence—as the sole basis for medical-necessity downcoding unless an employee or contractor of the insurer reviews the patient’s medical record.
It also:
Prohibits downcoding based solely on diagnosis codes
Requires disclosure when AI is used
Requires appropriate claim-adjustment and remittance codes
Establishes notice and appeal protections
Permits providers to dispute groups of similar claims
The Indiana provisions do not apply to Medicaid or Medicaid managed-care claims.
What Indiana providers can do: Document cases in which records were not requested or reviewed. Cite Indiana Code Chapter 27-1-52 in appeals and complaints involving state-regulated plans.
Virginia: Electronic downcoding remains permissible, but with guardrails
Virginia enacted SB 164/HB 484 in 2026.
The Virginia law is not a complete ban on automatic downcoding. It expressly permits an initial decision to be made by either a natural person or an electronic system, provided the system reflects correct coding standards and considers all relevant patient data documented by the billing provider on the claim submission.
The law also requires:
Notice that a claim was downcoded
Appropriate claim-adjustment and remittance codes
At least 180 days to initiate a dispute
The ability to dispute multiple claims in batches
Natural-person review and adjudication of all downcoding disputes
The important limitation is that human review is required during the dispute—not necessarily before the initial payment reduction.
What Virginia providers can do: Use the 180-day dispute period and batch-appeal rights. Providers can also advocate for stronger legislation requiring medical-record review before the original claim is reduced.
Arkansas: Notice is required, but downcoding is not prohibited
Arkansas enacted Act 136/HB 1287 in 2025.
The law defines downcoding and requires a contracting entity that downcodes a claim to notify the provider within 30 days after processing the claim.
It does not:
Prohibit automatic downcoding
Require medical-record review
Require review by a licensed clinician
Create a detailed provider appeal process
Arkansas has therefore addressed silent downcoding, but not the underlying practice itself.
What Arkansas providers can do: Track whether notice is actually received within 30 days. Arkansas providers can use those examples to advocate for human-review, appeal, and enforcement provisions in future legislation.
Illinois: Strong protections are enacted but delayed until 2028
Illinois enacted SB 3114, the Transparency in Downcoding Act, as Public Act 104-0568 on July 10, 2026.
The law prohibits a payer from implementing a policy, algorithm, or automated system that bypasses evaluation of information submitted by the billing healthcare professional. Automated tools may flag claims, but a natural person must make or review the downcoding decision.
The law also:
Prohibits diagnosis-only downcoding
Requires specific notice and explanations
Establishes dispute and appeal procedures
Prohibits discriminatory targeting of providers treating complex or chronic patients
Applies to Illinois Medicaid managed-care organizations
The problem is timing: the law does not take effect until January 1, 2028.
What Illinois providers can do: Begin collecting baseline data now. Practices will need evidence showing whether payer behavior changes when the law becomes effective. Providers should also watch for implementation guidance from the Illinois Department of Insurance and Department of Healthcare and Family Services.
States with active bills or organized legislative development
New Mexico: The NP Council is preparing for 2027
The New Mexico Nurse Practitioner Council is leading an active pre-legislative initiative for the 2027 New Mexico legislative session.
NMNPC is currently collecting information from NPs and practices, including:
Insurance company
When the downcoding began
Codes affected
Number of affected claims
Cost of preparing and pursuing appeals
There is no bill number, named sponsor, or published draft yet. New Mexico’s current status is best described as organized data collection and legislative development.
That still counts as genuine movement. Legislators are far more likely to respond when an organization can present documented statewide evidence instead of isolated anecdotes.
What New Mexico providers can do: Respond to NMNPC’s request even if the loss on each individual claim seems small. Include examples from commercial plans and Turquoise Care, and document whether records were reviewed before or only after payment was reduced.
New Jersey: Bills remain pending
New Jersey S 1022 and A 238 were introduced for the 2026–27 legislative session.
The bills would prohibit a health insurance claims payer from using downcoding in a manner that prevents a provider from submitting a claim and collecting reimbursement for the service actually performed.
The proposal is broader than automatic downcoding, but its current language does not provide all the safeguards found in Indiana or Illinois. For example, it does not establish the same detailed requirements for human review, diagnosis-only downcoding, notice, or batch appeals.
What New Jersey providers can do: Contact bill sponsors and insurance-committee members. Ask them to add explicit protections against sole algorithmic decision-making and the practice of requiring providers to prove their claims only after payment has already been reduced.
New York: Active legislation, but with a narrower scope
New York S 4833/A 3707 remain active in committee.
The bills would classify certain downcoding decisions as adverse determinations and prohibit downcoding that reverses or alters an existing medical-necessity determination.
That is important, but it is not a comprehensive ban on automatic E/M downcoding. The current language is tied primarily to situations involving an existing medical-necessity, site-of-service, or level-of-care determination.
What New York providers can do: Ask the Senate and Assembly Insurance Committees to advance the legislation and expand it to cover automatic code substitution even when no previous utilization-review decision exists.
States where 2026 legislation did not pass
A failed bill is not the end of an issue. It creates bill language, identifies potential sponsors, generates testimony, and gives advocates a place to begin during the next session.
Arizona
HB 2407 would have prohibited an automated system from making the final downcoding decision. It required a documented clinical review by an Arizona-licensed healthcare professional of the same specialty as the treating provider.
It also included notice, appeal, batch-dispute, diagnosis-only and anti-discrimination provisions. It did not pass before the 2026 session adjourned.
Next step: Ask Rep. Willoughby and Arizona NP organizations to refile the measure in 2027.
California
AB 2431 would have required documented review of the clinical information supporting the billed service. It also included notice, appeal, enforcement and protections for clinicians treating high-acuity, complex and chronic patients.
The bill was held in the Assembly Appropriations Committee on May 14, 2026, and did not pass.
Next step: Request reintroduction in 2027, preferably with the introduced version’s clearer prohibition against automated downcoding restored.
Connecticut
SB 342 included restrictions on software tools used to downcode or deny certain health insurance claims.
The bill reached the House calendar on May 6, 2026—the final day of the Connecticut session—but was not enacted.
Next step: Ask Insurance and Real Estate Committee members to introduce the downcoding provisions as a focused, standalone bill early in the 2027 session.
Florida
HB 1015 and SB 1130 would have restricted downcoding, required medical-record review in specified circumstances, and established notice, interest, enforcement, and private-remedy provisions.
Neither measure advanced during the 2026 session.
Next step: Ask Rep. Hillary Cassel, Sen. Stan McClain, Sen. Ralph Massullo, or other interested legislators to sponsor a focused 2027 measure.
Iowa
SF 2226 addressed automated adjudication systems used by health carriers, including systems used for downcoding and adverse claim decisions.
The bill was introduced, referred to the Senate Commerce Committee, and assigned to a subcommittee, but received no further action.
Next step: Send claim examples and financial data to the bill’s sponsors and request reintroduction in the next General Assembly.
Oregon
HB 4054 would have required insurers to notify providers whenever AI or other automated technology was used to downcode a claim. It also required an appeal process.
The bill did not prohibit automatic downcoding or require prepayment medical-record review. It remained in committee and was not enacted.
Next step: Seek a stronger replacement requiring clinical review before—not after—the payer reduces reimbursement.
Tennessee
SB 2020 would have prohibited health insurers from downcoding provider reimbursement claims except in limited circumstances.
The sponsor withdrew the bill on February 2, 2026.
Next step: Determine why the measure was withdrawn and recruit House and Senate sponsors for a revised 2027 proposal.
Where no direct downcoding movement was found
As of September 24, 2026, we found no direct downcoding legislation or organized initiative in:
Alabama, Alaska, Colorado, Delaware, Georgia, Hawaii, Idaho, Kansas, Kentucky, Louisiana, Maine, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Texas, Utah, Vermont, Washington, West Virginia, Wisconsin, Wyoming, and the District of Columbia.
Some of these jurisdictions have broader laws governing AI, prior authorization, utilization review, or adverse insurance decisions. Those laws may provide related protections, but they should not be described as automatic-downcoding laws unless they specifically regulate code substitution or reduced-code reimbursement.
Providers in these states do not need to wait for someone else to begin. New Mexico demonstrates how legislative development often starts: collect the evidence, quantify the harm, and approach professional organizations and lawmakers with a solution.
What every affected practice should document
If your practice is experiencing downcoding, preserve the following information:
Insurance company and plan name
Whether the plan is commercial, Medicaid, Medicare Advantage, or self-funded
Date the practice first noticed the policy
Original CPT code
Adjusted or paid CPT code
Original billed amount
Contracted amount for the original code
Amount actually paid
CARC and RARC codes on the remittance
Number of affected claims
Whether records were requested before the code was changed
Whether a licensed clinician reviewed the record
Time required to prepare each appeal
Staff, billing-company, consultant, postage, and portal costs
Date the appeal was filed
Appeal outcome
Time between the original claim and final payment
Whether the affected patients had complex, chronic, or high-acuity conditions
Remove patient identifiers before sharing examples for legislative or advocacy purposes unless the information is being submitted through an authorized, secure process.
“The insurer downcoded us” identifies a problem.
“Our practice documented 417 altered claims, $18,600 in reduced reimbursement, no prepayment record review, and $7,200 in appeal labor” creates a legislative case.
Plan type matters
State insurance laws generally do not reach every health plan.
Self-funded employer health plans are usually protected from direct state insurance regulation by ERISA. Medicare Advantage plans are predominantly governed by federal Medicare standards. Some state laws also expressly exclude Medicaid, while others specifically include Medicaid managed-care organizations.
Before citing a state law in an appeal, confirm:
Which entity issued the plan
Whether the plan is fully insured or self-funded
Which state regulates the policy
Whether the claim involves Medicaid or Medicare Advantage
Whether the law covers third-party administrators and delegated claims vendors
Providers cannot fix what they cannot see
Automatic downcoding can hide inside normal-looking remittance data. Practices should compare the CPT code submitted on the original claim with the code reflected on the remittance—not merely compare the billed amount with the amount paid.
Billing systems may treat the transaction as a standard contractual adjustment rather than flagging it as a denial. That means a practice can lose reimbursement repeatedly without generating an obvious appeal work queue.
Run reports. Compare codes. Review payer patterns. Calculate the cost of appeals. Then share the evidence with your state NP organization, medical association, insurance regulator, and legislators.
Four states have enacted direct downcoding legislation. Maryland’s insurance regulator has declared proactive unilateral downcoding impermissible under existing law. New Mexico is preparing for 2027. New Jersey and New York still have pending bills. Seven additional states already have bill language that can be revived.
The states without movement are not states where the problem does not exist. They are states where providers have not yet turned the problem into legislation.
