SunKnowledge Guides Hospitals Through FY 2027 Medicare Inpatient Billing Changes

SunKnowledge Services Inc., a healthcare revenue cycle management company, is helping hospitals prepare their inpatient billing operations for the fiscal year 2027 Medicare payment changes. The Centers for Medicare & Medicaid Services issued the FY 2027 Hospital Inpatient Prospective Payment System and Long Term Care Hospital Prospective Payment System final rule on July 31, 2026. The rule updates Medicare fee-for-service payment rates and policies for inpatient hospitals and long-term care hospitals for the fiscal year beginning October 1, 2026.

CMS finalized a 2.3% increase in IPPS payment rates for hospitals that successfully participate in the Hospital Inpatient Quality Reporting Program and qualify as meaningful electronic health record users. The increase reflects a projected 3.2% hospital market-basket update, reduced by a 0.9-percentage-point productivity adjustment. CMS estimates that the finalized IPPS rate changes, combined with other provisions, will increase hospital payments by approximately $2.1 billion in FY 2027.

However, a national payment-rate increase does not automatically translate into the same reimbursement improvement for every hospital. Actual payment continues to depend on several factors, including the Medicare Severity Diagnosis-Related Group assigned to the case, documented severity of illness, geographic wage adjustments, hospital-specific qualifications, quality program participation and other applicable payment policies. This makes coding, documentation and claim accuracy important components of FY 2027 revenue-cycle readiness.

"Annual Medicare payment changes affect more than a hospital's reimbursement rates," said Ronnie Hastings, spokesperson at SunKnowledge. "They can influence coding reviews, claim validation, denial patterns, underpayment analysis and revenue forecasting, and hospitals need to understand how the updated requirements connect with their day-to-day billing workflows before problems begin appearing in their accounts receivable."

Under the IPPS, Medicare generally pays applicable acute care hospitals a predetermined amount for each inpatient case. Cases are classified into MS-DRGs based on factors such as the patient's diagnoses, procedures, discharge status, age and, when applicable, documented complications or comorbidities. Incomplete clinical documentation, unsupported code selection or an inaccurate discharge status can affect the assigned MS-DRG and the resulting payment. These issues can also expose hospitals to claim delays, additional documentation requests, coding denials, DRG downgrades and post-payment reviews.

SunKnowledge supports hospital revenue-cycle teams by reviewing the operational areas most likely to influence claim accuracy and reimbursement. These include patient and insurance information, authorization status, charge capture, clinical documentation, diagnosis and procedure coding, MS-DRG assignment, claim edits, payer responses and outstanding balances. The company's hospital billing support covers inpatient institutional claims as well as associated outpatient and hospital-owned professional workflows, depending on the organization's requirements.

SunKnowledge is encouraging hospitals to review whether their documentation and coding processes accurately capture the clinical circumstances of each inpatient admission. This includes evaluating principal diagnosis selection, secondary diagnoses, present-on-admission indicators, inpatient procedure coding, discharge disposition and documentation supporting complications or comorbidities. Hospitals should also examine whether changes in payment policy, MS-DRG classification and payer claim edits have been incorporated into their billing systems and staff workflows.

Preparing for FY 2027 also requires attention after a claim has been submitted. Hospitals need processes for identifying whether a claim was denied, reduced, incorrectly processed or paid below the expected contractual or regulatory amount. SunKnowledge assists hospital teams with denial categorization, root-cause identification, corrected claims, appeals, payer follow-up and underpayment review. The company also supports aged accounts receivable management by prioritizing unresolved accounts according to factors such as balance, payer, denial reason, filing deadline and likelihood of recovery.

"Hospitals should not wait until aging accounts begin accumulating to evaluate the effect of new payment requirements," added Hastings. "A proactive review of documentation, coding, claims and payer follow-up can reveal where revenue leakage is occurring and where workflow changes may be necessary."

With the FY 2027 IPPS requirements taking effect on October 1, 2026, SunKnowledge recommends that hospitals assess their inpatient revenue-cycle workflows, system configurations, staff readiness and payer-monitoring processes as early as possible.
