Strategic Plan for Navigating 2025-2026 Medical Coding and Reimbursement Changes

Introduction

The healthcare landscape is in a state of continuous evolution, driven by advancements in medicine, shifts in regulatory policy, and the integration of new technologies. For healthcare organizations, proactively managing the upcoming changes in medical coding, billing, and reimbursement is not merely an administrative exercise—it is a critical imperative for survival and success. The period of 2025-2026 marks a significant inflection point, with financial headwinds, new coding requirements, and foundational policy shifts converging to create a complex operational environment. This document serves as a strategic roadmap for healthcare executives and practice managers, providing the analysis and actionable intelligence needed to ensure financial stability, enhance operational efficiency, and maintain rigorous regulatory compliance in the years ahead.

1.0 The Evolving Regulatory and Reimbursement Landscape

Understanding the macro-level shifts in policy and payment methodology from the Centers for Medicare & Medicaid Services (CMS) is the first step in developing an effective strategic response. The prevailing trends signal a clear and accelerating movement towards greater diagnostic specificity, incentives tied to value and quality, and the deeper integration of technology into both care delivery and reimbursement. These high-level currents are the driving force behind the granular code set changes and payment adjustments that will directly impact every healthcare provider.

1.1 Analyze Key Financial Headwinds in the Medicare Physician Fee Schedule (MPFS)

The most immediate challenge facing providers is a direct and significant reduction in reimbursement rates. The 2025 Physician Fee Schedule (MPFS) Proposed Rule outlines several direct financial pressures that will compress margins and strain operational budgets.

Conversion Factor Decrease: The MPFS conversion factor is projected to decrease by 3.9% in 2025 . This continues a troubling downward trend that has seen the factor fall from approximately $36 in 2019 t o a p ro j ec t e d$ 32 in 2025, eroding the fundamental value assigned to physician services.
Severe Reimbursement Declines: The impact of these cuts is stark when viewed at the procedural level. For example, the national reimbursement for CPT code 96413 (chemotherapy administration) has plummeted over the past six years from $143 t o a p ro j ec t e df i gu reo f a pp ro x ima t e l y$ 20 in 2025.
Rising Administrative Burden: These steep financial cuts are occurring in parallel with increasing administrative burdens. Providers are navigating a landscape of expanding prior authorization requirements, the complexities of new coding rules, and the operational demands of electronic health records, all of which add cost and complexity without corresponding payment increases.

1.2 Evaluate Foundational CMS Policies Impacting Operations

Beyond direct payment cuts, two long-standing CMS policies continue to shape daily operations and carry significant compliance risk. A renewed focus on these rules is essential for avoiding denials and financial penalties.

The Two-Midnight Rule: Established to address extended outpatient stays, this rule serves as the benchmark for determining whether an inpatient admission is “reasonable and necessary” for Medicare Part A payment. It provides critical guidance for assigning correct patient status, a frequent target of payer audits.
The National Correct Coding Initiative (NCCI): The NCCI’s primary function is to promote correct coding and prevent improper payments for Medicare Part B claims. Based on CPT conventions, national policies, and standard medical practices, the initiative uses Procedure-to-Procedure (PTP) edits and Medically Unlikely Edits (MUEs) to identify and block services that should not be billed together. For example, PTP edits prevent payment for a component procedure if it is already included in a more comprehensive procedure performed at the same time, while MUEs prevent billing for a number of units of service that would be medically impossible or improbable in a single day.

1.3 Assess the Integration of Technology in Future Reimbursement Models

CMS is actively signaling its intent to integrate digital health tools into future payment models, creating both new opportunities and new complexities for providers.

In a forward-looking proposal for CY 2026, CMS is considering establishing separate coding and payment for digital tools that support healthy lifestyles as part of a mental health treatment plan.
More broadly, CMS is actively seeking comments and stakeholder feedback on how to appropriately pay for Software as a Service (SaaS) and devices utilizing augmented intelligence (AI) under the MPFS. This indicates that formal policy development is on the horizon, and providers who prepare now will be best positioned to capitalize on these future models.

These high-level policy directions are not abstract concepts; they are the strategic drivers that directly inform the granular changes to the medical code sets that will define operational and financial performance.

2.0 Strategic Analysis of Major 2025-2026 Code Set Updates

Mastering the annual updates to medical code sets is of paramount strategic importance. These changes are not merely administrative; they are a direct reflection of advancements in medicine, shifts in public health priorities, and an escalating demand for data-driven healthcare. The updates for 2025-2026 require a new level of documentation and coding precision to ensure accurate reimbursement and quality reporting.

2.1 Deciphering Key ICD-10-CM Updates (Effective October 1, 2025 )

The upcoming changes to the ICD-10-CM code set introduce greater specificity across a wide range of clinical areas. The following table summarizes the most significant updates that will require focused education and documentation improvement.

Clinical Area/Concept	Summary of 2025/2026 Updates
Oncology	New codes have been added to differentiate various types of lymphoma that are in remission, enabling more precise tracking of patient outcomes and resource use.
Endocrinology	Includes new codes for presymptomatic Type 1 diabetes and additions to specify the level and class for Hypoglycemia and Obesity, enhancing data on disease progression.
Genetic/Blood Disorders	A new code has been introduced for Fanconi anemia, a rare inherited blood disorder, allowing for better tracking and research.
Nervous System & Mental Health	New codes are available for serotonin syndrome. Additionally, new codes have been added to specify the type and severity of various eating disorders.
Cardiopulmonary	Introduces new codes for cement embolism of the pulmonary artery and fat embolism of the pulmonary artery, often linked to orthopedic procedures.
Social Determinants of Health (SDoH)	The Z-code category has been expanded to include new codes that capture problems related to upbringing (e.g., Z62 codes), reflecting the growing importance of SDoH data.

It is critical to note that the FY 2026 Official Guidelines for Coding and Reporting will be updated to incorporate these changes. Coders and clinical staff must be trained on the new instructions to ensure compliant reporting.

2.2 Evaluating High-Impact CPT® and HCPCS Level II Changes

Updates to the CPT and HCPCS code sets reflect new technologies, evolving standards of care, and revised payment policies.

Overall CPT 2025 Update: The American Medical Association (AMA) has released 420 updates for 2025, including 270 new codes. The largest proportions of new codes are assigned to proprietary laboratory analyses (PLA) and Category III codes, which represent emerging technologies and procedures.
Evaluation & Management (E/M): CMS has introduced two important add-on codes. HCPCS code G2211 is designed to capture the additional complexity inherent in managing ongoing care relationships. HCPCS code G2212 has been created for prolonged office or outpatient E/M services.
Telehealth Services: While many COVID-19-era flexibilities expired at the end of 2024, CMS has added new services to the permanent telehealth list for 2025, such as caregiver training. A significant new rule, effective January 1, 2025, allows for audio-only communication for telehealth services furnished to a patient in their home, provided the distant site practitioner is video-capable but the patient is not.
Surgical and Procedural Codes: A new postoperative add-on code, G0559, has been created for post-care services related to 90-day global procedures. Additionally, there are revisions regarding skin grafts, wound care, and advancements in surgical techniques for abdominal tumors.
HCPCS Level II (Drugs & Biologicals): CMS updates these codes on a quarterly basis to keep pace with pharmaceutical innovation. For example, in Q2 2025, new codes were established for biosimilars and other drugs, including Q5158 (denosumab-bnht) and J9011 (datopotamab deruxtecan-dlnk), underscoring the rapid pace of change.

2.3 Articulate the Strategic Value of Enhanced Coding Specificity

The consistent trend toward more granular and specific codes has profound strategic implications. This is not just an administrative burden; it is a fundamental shift in how patient care is documented, measured, and paid for.

The increased specificity in ICD-10-CM—for areas like SDoH, lymphoma remission status, and diabetes subtypes—directly impacts risk adjustment, Hierarchical Condition Category (HCC) coding, and quality reporting frameworks.
Precise coding is no longer just for submitting a bill. It is now fundamental to accurately demonstrating patient complexity, justifying resource utilization, and proving the value of care delivered. In value-based payment models, this level of detail is the foundation upon which financial performance is built.
This granularity is the raw data that fuels performance in the Quality Payment Program (as detailed in Section 3.3) and is foundational to succeeding in emerging payment models like the Ambulatory Specialty Model (ASM) mentioned in our long-term roadmap.

These code set modifications translate directly into tangible financial consequences, which must be carefully assessed and managed.

3.0 Financial Impact Assessment and Mitigation Strategies

This section provides the critical link between the identified regulatory and coding changes and the organization’s financial health. The following analysis quantifies the primary risks and opportunities presented by the new reimbursement landscape. This assessment provides the financial rationale for making strategic investments in compliance, training, and operational improvements to safeguard revenue and maintain fiscal stability.

3.1 Quantifying the Impact of the Medicare Physician Fee Schedule (MPFS)

The MPFS changes represent the most direct and immediate threat to provider revenue.

The projected 3.9% reduction in the 2025 conversion factor is the primary driver of revenue decline, applying a broad-based cut across nearly all physician services.
The practice expense (PE) Relative Value Unit (RVU) calculation, which is intended to cover both direct costs (supplies, clinical labor) and allocated indirect costs (rent, nonclinical staff), is also a source of financial pressure.
Using CPT 96413 (chemo administration) as an example, budget neutrality adjustments and shifts in cost allocation methodologies can lead to a year-over-year decrease in the PE RVU itself—from 3.53 to 3.36. This further compresses margins on top of the broader conversion factor reduction.

This illustrates a dual financial assault: a macro-level reduction in the value of all services via the conversion factor, compounded by a micro-level erosion of margins on specific, high-volume procedures through PE RVU adjustments.

3.2 Analyzing Inpatient Reimbursement under MS-DRGs

For inpatient facilities, the Medicare Severity-Diagnosis Related Group (MS-DRG) system remains the cornerstone of payment, and it carries its own distinct financial risks.

The MS-DRG system forms the basis for Medicare’s inpatient prospective payment system (IPPS), where hospitals receive a predetermined payment amount based on the patient’s principal diagnosis, procedures, and secondary conditions.
Accurate documentation and coding of all relevant Complications and Comorbidities (CCs/MCCs) is essential. The presence of a valid CC or MCC can shift a case to a higher-weighted, and therefore higher-paying, MS-DRG. Failure to capture these conditions results in lost revenue.
A significant financial penalty is associated with Hospital-Acquired Conditions (HACs). HACs are defined as harmful conditions or negative outcomes (such as a catheter-associated urinary tract infection) that a patient develops during an inpatient admission that were not present upon arrival. As mandated by the Deficit Reduction Act of 2005 (DRA), CMS eliminates any payment increase that results from a HAC. This policy underscores the critical importance of accurate Present on Admission (POA) indicator reporting to differentiate conditions that developed post-admission from those that were already present.

3.3 Evaluating Financial Risk in the Quality Payment Program (QPP)

Performance in the Merit-based Incentive Payment System (MIPS), a track within the QPP, is directly tied to future payment adjustments.

For the 2026 performance period (which will affect 2028 payments), CMS is maintaining the MIPS performance threshold at 75 points. Clinicians with final scores below this threshold will receive a negative payment adjustment of up to ** -9%**.
CMS data highlights a disproportionate risk for smaller organizations. It is estimated that 49% of solo practitioners and 21% of small practices will receive a penalty, compared to just 12% of MIPS-eligible clinicians overall. This makes successful MIPS participation a critical financial priority for these groups.

Mitigating these diverse financial risks is not possible without investing in robust operational processes, sophisticated systems, and a well-trained, knowledgeable team.

4.0 Operational Readiness and Implementation Plan

This section represents the action-oriented core of the strategic plan. The following four initiatives are designed to build the necessary infrastructure, skills, and workflows to navigate the identified changes effectively. These are not merely compliance measures; they are proactive investments designed to convert regulatory burdens into strategic assets that improve data quality, patient outcomes, and market position.

4.1 Initiative 1: Strengthen Clinical Documentation Integrity (CDI)

As advised by CMS, clear and concise medical record documentation is the foundation of quality care and correct payment. A robust CDI program is essential to meet the heightened specificity requirements of modern coding systems.

Mandate a formal documentation review process. This process must ensure every diagnosis is supported by related signs, symptoms, test results, and the clinical rationale for treatment. Medication lists must clearly link each drug to the condition(s) it is prescribed to treat.
Implement a formal physician query process. A structured, compliant query process is the most effective tool for clarifying ambiguous, conflicting, or incomplete physician documentation. This is critical for achieving the highest level of specificity required by new ICD-10-CM codes and justifying medical necessity.

A successful CDI program is the primary defense against the financial risks outlined in Section 3.0. It directly enables the capture of CCs/MCCs to secure appropriate MS-DRG payment, justifies medical necessity to withstand Two-Midnight Rule audits, and provides the specific data required to maximize MIPS scores.

4.2 Initiative 2: Enhance Coder and Clinician Education Programs

A well-educated team is the organization’s first line of defense against coding errors and compliance risks. A multi-faceted educational strategy is required.

Develop a multi-modal educational schedule. Utilize a mix of face-to-face training sessions, newsletters, and quick-reference fact sheets tailored to the specific needs of different audiences, including coders, physicians, and practice managers.
Deliver targeted training content. Curriculum must cover the new 2025/2026 ICD-10-CM and CPT codes, official updates to the coding guidelines, and the correct application of key coding conventions, such as ‘Excludes1’ notes (which indicate two conditions that cannot be reported together).
Focus on high-impact areas. Training must emphasize proper Evaluation & Management (E/M) code selection based on either time or Medical Decision Making (MDM), including the correct use of new add-on codes G2211 and G2212.

4.3 Initiative 3: Optimize Billing and Claims Adjudication Workflows

The revenue cycle team must be equipped with the knowledge and tools to navigate complex payment rules and prevent avoidable denials.

Master National Correct Coding Initiative (NCCI) edits. The team must regularly review the NCCI Policy Manual and use the Correct Coding Modifier Indicator (CCMI) to determine when a modifier is allowed to bypass a Procedure-to-Procedure (PTP) edit (Indicator ‘1’) versus when two codes can never be billed together (Indicator ‘0’).
Provide clear guidance on modifier application. Develop protocols for the appropriate use of key modifiers, including Modifier 25 (for a significant, separately identifiable E/M service on the same day as a minor procedure) and Modifier 57 (for an E/M service that results in the decision to perform a major surgical procedure).
Establish protocols for patient status determination. To ensure compliance with the Two-Midnight Rule and prevent costly inpatient-level-of-care denials, create clear, evidence-based protocols for assigning patient status. The 6-month look-back period for Recovery Auditor reviews serves as a powerful incentive for getting these determinations right the first time.

4.4 Initiative 4: Technology and Systems Assessment

The organization’s technology infrastructure must support and enable compliance with the new coding and billing requirements.

Mandate a review of all critical software. Work with vendors to confirm that the EHR, practice management, and billing software systems have been updated with the complete 2025/2026 code sets and associated payment logic.
Verify claims scrubber and editor alignment. Instruct IT and billing leadership to ensure that all claims scrubbing software is aligned with the latest NCCI PTP and MUE updates. This is crucial for preventing automated denials and improving first-pass payment rates.
Initiate a strategic review of emerging technologies. To prepare for future CMS payment policies, form a team to assess the potential of new SaaS and AI-powered tools that could enhance documentation, coding, and care management.

These operational initiatives are the foundational building blocks for executing the overarching strategic roadmap outlined in the final section of this plan.

5.0 Strategic Recommendations and Action Roadmap

Successfully navigating the multitude of changes coming in 2025-2026 demands a phased, deliberate, and coordinated approach. Simply reacting to new rules as they become effective is a recipe for compliance failures and financial shortfalls. The following roadmap provides a clear, actionable guide for leadership to execute this strategy over the next 24 months. Organizations that master these changes will not only protect their current revenue but will be better positioned to thrive in future value-based arrangements and outperform competitors in quality and efficiency metrics.

5.1 Immediate Priorities (Next 90 Days)

These are the most urgent action items to ensure foundational readiness for the upcoming changes.

System Verification: Confirm with all EHR, billing, and coding software vendors that the October 1 ICD-10-CM updates and the upcoming January 1 CPT/HCPCS updates have been fully integrated and tested in all production systems.
Initial Training Deployment: Roll out high-level awareness and training on the most impactful and immediate code changes to all clinical and administrative staff. This should include new E/M guidelines (G2211, G2212), key new diagnosis codes (e.g., lymphoma in remission, SDoH), and telehealth rule changes.
Financial Impact Modeling: Task the finance and analytics departments with modeling the projected revenue impact of the 2025 MPFS conversion factor reduction and PE RVU changes. This analysis should focus on the organization’s top 20-30 most frequently billed services to quantify the most significant financial risks.

5.2 Mid-Term Goals (6-12 Months)

This phase focuses on embedding new processes, validating performance, and optimizing operations.

Comprehensive Auditing: Conduct a baseline comprehensive coding audit across all major service lines to identify systemic documentation and coding gaps. Follow this with targeted DRG validation audits focused on high-volume, high-risk, and high-reimbursement inpatient cases to ensure financial accuracy.
CDI Program Optimization: Fully implement the formal physician query process outlined in the operational plan. Critically, establish a feedback loop where findings from coding audits are used to create targeted, provider-specific education to address root-cause documentation issues.
Process Refinement: Update and formalize all internal billing policies and standard operating procedures to reflect a deep, institutional understanding of NCCI edits, correct modifier application, and the documentation requirements of the Two-Midnight Rule.

5.3 Long-Term Strategic Positioning (12-24 Months)

This final phase transitions the organization from a reactive compliance posture to a proactive strategic stance, preparing for the future of reimbursement.

Prepare for New Payment Models: Begin detailed research and operational planning for participation in emerging CMS payment models. A key focus should be the proposed Ambulatory Specialty Model (ASM), understanding its participation requirements, performance measures, and financial implications.
Digital Health Integration: Develop a formal strategy for incorporating and correctly billing for new telehealth services, remote patient monitoring, and other digital health tools. This strategy should anticipate evolving CMS payment policies for Software as a Service (SaaS) and AI-driven technologies.
Continuous Improvement Framework: Establish a permanent, interdisciplinary Revenue Cycle and Compliance Committee. This group—comprising leaders from finance, compliance, Health Information Management (HIM), and key clinical departments—will be responsible for continuously monitoring the regulatory environment. Its mandate is to move the organization from a reactive, compliance-focused posture to a proactive, forward-looking one, enabling it to anticipate and capitalize on industry shifts rather than merely responding to them.
