Cardiac Arrhythmia and Conduction Disorders with MCC in Washington
44 Washington hospitals report Medicare totals for this DRG, averaging $13,117 (above the $11,768 national mean), with a 3× spread from $6,912 to $17,334. 1 carry an A grade, 0 carry an F.
The Cardiac procedure Cardiac Arrhythmia and Conduction Disorders with MCC carries DRG code 308 in the CMS classification system. 2,745 hospitals in Washington report payment data, averaging $11,768 per procedure — median $11,444, ranging from $4,039 to $25,428. The $4,039-to-$25,428 payment range is wide: the same DRG code can attract very different reimbursements across hospitals, reflecting differences in cost structure, patient complexity within the DRG, and regional pricing dynamics. The Medicare DRG system bundles cases by diagnosis-and-procedure groupings, so payment differences within a single DRG mostly track hospital-specific factors rather than case-mix.
Within Washington, the 2,745 hospitals reporting this procedure span the full range of ownership types and hospital sizes. The state-specific average ($11,768) is shaped by which hospitals in the state see enough volume to report the DRG code at all. For patients with elective scheduling on Cardiac Arrhythmia and Conduction Disorders with MCC, the cost-comparison logic is straightforward: the per-procedure payment range is meaningfully wide, so the hospital chosen affects total cost. For patients in an emergency, the choice is functionally fixed — but the listed prices still matter for insurance-coverage and out-of-pocket planning.
About This Procedure
Cardiovascular DRGs cover heart attack, coronary bypass, valve replacement, vascular surgery, and arrhythmia management. These procedures combine high implant costs with intensive perioperative monitoring, which is why they consistently rank among the most expensive Medicare DRGs.
Cardiac Arrhythmia and Conduction Disorders with MCC is Medicare DRG 308 in the Cardiac category. National Medicare average for this DRG is $11,768 across 2,745 reporting hospitals. The state-level view here filters that universe down to Washington only.
Cost Picture in Washington
Washington's average for this DRG sits above the national Medicare mean. State-level differences are explained primarily by the regional Medicare wage index — the multiplier CMS applies to standardize DRG payments to local labor costs — alongside hospital case mix and the concentration of academic referral centers in the state's larger metros.
Within the state, the 3× spread between the lowest- and highest-reporting facility usually reflects length-of-stay differences, complication adjustments for sicker patients, teaching-status add-ons, and outlier payments for unusually long stays. Two hospitals reporting the same DRG can post meaningfully different totals without anything “wrong” happening at either site. For non-Medicare patients, the more relevant figure is the negotiated commercial rate published in each hospital's machine-readable file under the CMS Hospital Price Transparency Rule.
Quality Alongside Price
For a planned admission, the most useful complement to the cost view is the hospital-specific quality data on CMS Care Compare. The site publishes risk-adjusted measures of mortality, readmission, complication, infection, and patient experience for every Medicare-participating hospital. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators feed many of these CMS measures.
For complex procedures, hospital-level case volume correlates with outcomes in published research, even after risk adjustment. CMS publishes case counts on Care Compare alongside outcome measures.

Frequently Asked Questions
How much does cardiac arrhythmia and conduction disorders with mcc cost in Washington?
Cardiac Arrhythmia and Conduction Disorders with MCC (DRG 308) averages $13,117 in total Medicare payment across 44 Washington hospitals reporting this code. Within the state, payments span $6,912 to $17,334 — about 3× from cheapest to most expensive.
Is Cardiac Arrhythmia and Conduction Disorders with MCC more or less expensive in Washington than nationally?
Washington's state-level average of $13,117 sits above the national Medicare average of $11,768 for this DRG. State differences are driven primarily by the regional Medicare wage index, case mix, and the share of high-acuity referral hospitals.
Why is the spread between hospitals so wide?
Variation within a state runs 3× because the same DRG can come with different lengths of stay, complication adjustments, teaching-status add-ons, and outlier payments. The CMS Hospital Price Transparency Rule publishes machine-readable rate files that allow direct comparisons against negotiated commercial rates, which often differ from Medicare totals.
Are these the prices a privately insured patient would pay?
No. Figures here are Medicare DRG payments. Privately insured patients are billed under their plan's negotiated network rate, published in each hospital's price-transparency file. Uninsured patients should ask the hospital for the cash-pay rate, also disclosed under federal price-transparency rules.
Should I choose a hospital based only on price?
No. HospitalCostData is informational. Surgeon experience, hospital volume for the procedure, complication rates, and your specific clinical situation matter at least as much as price. Always discuss options with your physician and review CMS Care Compare quality data alongside any pricing benchmark.
