Case Mix Indexratio

case_mix_index
Typical: 1.20-2.50
Definition

Average DRG weight across discharges — a complexity proxy.

Why it matters

Each 0.05 CMI uplift ≈ 0.75% of Medicare revenue. CDI initiatives target this lever.

How calculated

Σ (DRG weight × discharges) / total discharges. CMS DRG weights are the rate table.

Clean Claim Rate%

clean_claim_rate
Typical: 85-96% (best ≥96%)
Definition

Share of claims accepted on first submission without rework.

Why it matters

High clean-claim rate cuts follow-up FTE cost and shortens AR. Each 1pp lift saves the cost of one rework × claims volume.

How calculated

Claims accepted first-pass / total claims submitted. Front-end coding + eligibility verification drive this.

Commercial Payer %%

commercial_pct
Typical: 20-50%
Definition

Share of total revenue or patient days attributable to commercial (non-government) payers.

Why it matters

Highest reimbursement index (~1.0). Each pp of commercial mix lifts NPR/charge directly. Concentration risk if a single payer >40%.

How calculated

Commercial revenue / total revenue (or commercial days / total days).

Cost to Collect%

cost_to_collect
Typical: 2-5% (best ≤3%)
Definition

RCM operating cost as a share of net patient service revenue.

Why it matters

Direct EBITDA leverage — every 1pp reduction drops to the bottom line. Above 4% suggests automation upside.

How calculated

Total RCM cost (FTEs + tech + outsourced vendors + bad debt processing) / NPSR.

Days Cash on Handdays

days_cash_on_hand
Typical: 30-200 (≥100 healthy)
Definition

How many days of operating expense the hospital can cover from current cash.

Why it matters

<30 days = covenant-trip risk; <15 = restructuring territory. Above 100 = healthy.

How calculated

Cash + cash equivalents / (annual operating expense / 365).

Days in A/Rdays

days_in_ar
Typical: 38-65 (best <38)
Definition

Average days accounts receivable spends outstanding before collection.

Why it matters

Each day reduction releases ~NPSR/365 of working capital. Long DSO ties up cash and predicts bad debt write-offs.

How calculated

(AR balance / annual NPSR) × 365. National median ~45 days; >55 = working-capital trapped; <38 = best in class.

Debt to Revenueratio

debt_to_revenue
Typical: 0.2-1.5x
Definition

Long-term debt as a multiple of net patient service revenue.

Why it matters

>1.0x typically requires above-average margin to service. Drives covenant attention.

How calculated

Long-term debt / NPSR.

Denial Rate%

denial_rate
Typical: 5-15% (best in class <5%)
Definition

Share of submitted claims initially denied by the payer (before appeals).

Why it matters

Each 1pp reduction recovers ~35% × NPSR in avoidable revenue. Denials drive bad debt and rework cost — the highest-leverage RCM lever.

How calculated

Denied claims / total claims submitted. Source: HFMA MAP Keys; partner-supplied or predicted from public-data features.

EBITDA Margin%

ebitda_margin
Typical: 8-18%
Definition

Earnings before interest, tax, depreciation, amortization, divided by NPSR.

Why it matters

PE benchmark for sponsor-quality cash generation. <8% raises questions; >15% is the platform-grade band.

How calculated

EBITDA / NPSR. EBITDA reconstructed from HCRIS operating income + D&A + lease normalization.

Expense per Bed$/bed

expense_per_bed
Typical: $0.7M-$2.0M/bed
Definition

Total operating expense normalized by licensed bed count.

Why it matters

Cost-density benchmark. High expense/bed with low revenue/bed signals labor or supply inefficiency — the synergy diligence target.

How calculated

Operating expenses / licensed beds. Source: HCRIS Worksheet G-3.

First-Pass Resolution%

first_pass_resolution_rate
Typical: 80-92%
Definition

Share of claims paid in full on the first attempt (no resubmission, no appeal).

Why it matters

Catches both denial and underpayment leak. Each 1pp lift saves rework-cost and shortens AR aging.

How calculated

Claims paid in full first-pass / total claims. Tighter than clean_claim_rate because it tracks payment, not acceptance.

FTE per AOBratio

fte_per_aob
Typical: 4.5-7.0
Definition

Full-time-equivalent staff per adjusted occupied bed — the canonical staffing intensity metric.

Why it matters

>7.0 = overstaffed (right-sizing opportunity); <4.5 = lean (often a quality risk).

How calculated

Total FTEs / adjusted occupied beds. Source: HCRIS Worksheet S-3 Part II + S-3 Part I.

Interest Coveragex

interest_coverage
Typical: 2.0-8.0x
Definition

EBIT divided by interest expense — how many times over EBIT covers interest.

Why it matters

Below 2.0x is the credit-attention zone; <1.5x raises restructuring discussion.

How calculated

EBIT / interest expense. From HCRIS G-2 + footnotes.

Labor % of NPSR%

labor_pct_of_npsr
Typical: 45-60%
Definition

Total labor cost as a share of net patient service revenue.

Why it matters

>60% is the labor-pressured band. Right-sizing or wage normalization typically takes 1-3pp out.

How calculated

Total labor cost (Worksheet A col 1+2 + benefits) / NPSR.

Medicaid Day %%

medicaid_day_pct
Typical: 10-30%
Definition

Share of total inpatient days attributed to Medicaid beneficiaries.

Why it matters

Lowest reimbursement index (~0.58). High Medicaid % drives DSO + denial rate up.

How calculated

Medicaid patient days / total patient days.

Medicare Day %%

medicare_day_pct
Typical: 30-55%
Definition

Share of total inpatient days attributed to Medicare beneficiaries.

Why it matters

Drives reimbursement index — higher Medicare % means lower NPR per gross charge (~0.79 vs 1.00 commercial).

How calculated

Medicare patient days / total patient days. Source: HCRIS Worksheet S-3 Part I.

Net Collection Rate%

net_collection_rate
Typical: 92-99% (best ≥97%)
Definition

Share of net realizable revenue actually collected (after contractual allowances).

Why it matters

Every 1pp lift drops to EBITDA. Below 95% signals process leak; <93% is distressed.

How calculated

Cash collected / (gross charges − contractual adjustments). Excludes bad debt write-offs.

Net Patient Revenue$

net_patient_revenue
Typical: varies by bed count and acuity
Definition

Patient-service revenue net of contractual allowances and bad debt — the topline line underwriters anchor every multiple to.

Why it matters

Primary scale driver. Multiples (EV/NPR, EV/EBITDA) and lever-impact estimates all flow from NPR. Trend is the leading indicator of demand and pricing power.

How calculated

Gross charges − contractual allowances − bad debt provision. Source: HCRIS Worksheet G-3 Line 3 or partner-supplied audited financials.

Net-to-Gross Ratio%

net_to_gross_ratio
Typical: 22-38% (acute care)
Definition

Net patient revenue as a fraction of gross charges — the realization rate.

Why it matters

Payer-mix-driven; highly stable within a hospital. Sudden compression signals contract loss or payer aggression. Wide variance vs peers (>5pp) warrants a contract-by-contract walk.

How calculated

Net patient revenue / gross charges.

Occupancy Rate%

occupancy_rate
Typical: 55-80%
Definition

Share of staffed beds occupied — patient days / bed-days available.

Why it matters

Drives fixed-cost absorption. Below 50% the hospital can't cover overhead; above 80% constrains throughput.

How calculated

Total patient days / bed-days available. Source: HCRIS Worksheet S-3 Part I.

Operating Margin%

operating_margin
Typical: -5% to +12%
Definition

Operating income as a share of net patient service revenue.

Why it matters

The single best summary of asset health. <0% is distressed; >5% is sustainable; >10% is best-in-class for community hospitals.

How calculated

(Net patient revenue − operating expenses) / net patient revenue. Source: HCRIS Worksheet G-2.

Payer Diversity Indexindex (0-1)

payer_diversity
Typical: 0.55-0.78 (best-in-class >0.7)
Definition

Inverse-Herfindahl concentration index across the payer mix; higher = more diverse, lower = more concentrated.

Why it matters

Concentration is the silent risk: one Medicare Advantage contract renegotiation can move 20% of revenue. Higher diversity = lower contract-renewal risk.

How calculated

1 − Σ(payer_share²) across the mix. Range 0 (single payer) to ~0.8 (very diverse).

Revenue per Bed$/bed

revenue_per_bed
Typical: $0.8M-$2.5M/bed
Definition

Net patient revenue normalized by licensed bed count.

Why it matters

Captures pricing × throughput in one number. Best-in-class acute hospitals run $1.5-2.5M/bed; lower suggests under-occupancy or weak payer mix; higher suggests outpatient skew or premium markets.

How calculated

Net patient revenue / licensed beds.

Total Patient Daysdays

total_patient_days
Typical: varies by bed count
Definition

Annual total of inpatient days across all service lines.

Why it matters

Volume baseline for occupancy, payer-mix calculations, and capacity-planning. The denominator most other partner ratios are normalized against.

How calculated

Sum of daily inpatient census across the fiscal year. Source: HCRIS Worksheet S-3 Part I.
