*Prevalence of each ICD-10 subchapter among top 1% beneficiaries. For example, 12.2% of top 1% beneficiaries were treated for renal failure.
†Sum of total treatment costs per ICD-10 subchapter. For example, treatment of renal failure accounted for 6.8% of total expenditures of top 1% beneficiaries.
‡Percentage of top 1% with this ICD-10 subchapter as most cost-incurring condition. For example, 6.4% of top 1% beneficiaries had renal failure as most cost-incurring condition.
§Percentage most cost-incurring condition relative to prevalence: fourth column divided by second column. For example, for 52.4% of top 1% beneficiaries who were treated for renal failure, this was also their most cost-incurring condition.
¶Percentage of costs accounted for by the most cost-incurring condition. For example, among top 1% beneficiaries with renal failure as most cost-incurring condition, this disease accounted for on average 66% of total costs per beneficiary.
