AR Days, Clean Claim Rate and the Other RCM Numbers a Hospital CFO Should Track
SRF Capital Studio Research DeskFunding Intelligence, SRF Capital StudioMost Indian hospitals know their revenue and their bed occupancy to the decimal, and their AR days only roughly. Here are the seven revenue cycle numbers worth tracking, with formulas and rupee examples.
Summary
- AR days is the single number that tells a hospital CFO how much earned revenue is sitting uncollected, and in Indian hospitals with heavy TPA and scheme exposure it is often far above the 30 to 60 days US benchmarks treat as normal.
- It only improves when the numbers upstream improve: clean claim rate, initial denial or disallowance rate, and how many rejected claims are fixed on the first attempt.
- Track them by payer, every month, and use the same set to judge any RCM vendor you hire or invest in.
Hospital finance teams in India track occupancy, average revenue per bed and doctor payouts closely. Ask for AR days by payer, or the share of claimed amount each TPA deducted last quarter, and the answer is usually an estimate.
That gap matters because the revenue cycle is where a hospital's margin is either banked or quietly lost. The seven indicators below are the ones we ask for first when we look at a hospital's finances, and the same seven are the right way to judge an RCM vendor. For how the stages behind them fit together, see our sector report on revenue cycle management.
1. Days in accounts receivable (AR days)
What it measures: how many days of revenue are sitting uncollected at a point in time.
Formula: closing receivables divided by average daily net revenue, where average daily net revenue is annual net revenue divided by 365.
Benchmark: HFMA's benchmarking for US providers commonly cites 30 to 60 net days as the normal range, with the best performers near the bottom of it. Indian hospitals with a large share of scheme and TPA business frequently run well above that. The benchmark matters less than the trend and the split by payer.
What it costs. Take a hospital with ₹80 crore of annual net revenue and ₹20 crore of receivables. Daily net revenue is about ₹21.9 lakh, so AR days are roughly 91. Bring that to 60 days and receivables fall to about ₹13.2 crore, releasing ₹6.8 crore of cash. If that cash would otherwise be borrowed at 10%, the saving is about ₹68 lakh of interest a year, before counting the claims that stop ageing into write-offs.
AR days is not a collections metric. It is the size of the loan your hospital is making to its payers, interest-free.
Always split AR days by payer group: cash, private insurers through each TPA, PM-JAY and state schemes, CGHS and ECHS, corporates. A single blended number hides the one payer that is dragging the rest.
2. Clean claim rate
What it measures: the share of claims that pass all checks and go to the payer without anyone having to correct them.
Formula: claims submitted without manual intervention divided by total claims submitted, over the same period.
Benchmark: HFMA's MAP Keys use 95% as the reference point in the US. Indian hospitals rarely measure it at all. Start by counting how many cashless files are returned by the TPA for missing documents or queries before a decision.
A low clean claim rate shows up later as higher AR days, more rework and more deductions. It is the earliest warning in the cycle, and the cheapest one to act on.
3. Initial denial rate, and its Indian cousin, the disallowance rate
In the US: the share of claims a payer initially refuses. Kodiak Solutions, which benchmarks more than 2,100 US hospitals, reported 11.81% in 2024, up from about 10.2% in 2020. Only 2.8% of claims ended as final denials, which tells you most initial denials are recoverable with work.
In India: outright rejections matter, but the bigger loss is usually partial: an insurer or TPA pays the claim and deducts items it considers non-payable, above the room-rent limit or unsupported by documents. IRDAI data for 2023-24 showed insurers disallowed about ₹15,100 crore, 12.9% of the amount claimed, and repudiated another ₹10,937 crore.
Formula: amount deducted divided by amount claimed, by payer and by reason. Track it monthly. Our piece on hospital payer mix and package rates explains why the same procedure can earn very different amounts across payers, and the denial management guide shows how to work the deductions.
4. First-pass resolution rate
What it measures: of the claims that were denied, queried or short-paid, the share fixed and paid on the first resubmission or appeal.
Why it matters: every additional round of correspondence costs staff time and adds weeks to AR days. A team that resolves most issues at the first attempt is working from root causes; a team that needs three rounds is guessing.
5. Net collection rate
What it measures: of what the hospital was entitled to collect after contractual adjustments (package rates, agreed tariffs, scheme rates), how much it actually collected.
Formula: payments received divided by (gross charges minus contractual adjustments), over a period long enough for claims to settle.
Why it matters: this is the number that separates a legitimate discount from a leak. A tariff agreed with an insurer is a pricing decision; a deduction for a missing discharge summary is a process failure. Net collection rate isolates the second.
6. Cost to collect
What it measures: everything the hospital spends to get paid, as a share of cash collected. That includes billing and insurance desk salaries, TPA coordinators, software, any outsourced RCM fees and the finance cost of carrying receivables.
Why it matters: it is the fair way to compare an in-house team with an outside vendor. A vendor that charges more but raises net collection and cuts AR days can lower the true cost to collect.
7. Discharge-to-bill and bill-to-settlement time
What it measures: the hours from a discharge decision to a complete final bill and claim file, and the days from submission to payment.
Why it matters in India: IRDAI's May 2024 master circular requires insurers to decide final discharge authorisation within three hours of the hospital's request. A hospital whose file takes six hours to assemble is the cause of its own delay, and of patients waiting in beds that could be earning.
Using the same numbers to judge an RCM vendor
An investor or acquirer looking at an RCM services company should ask for the same indicators, measured across the vendor's clients, plus four of its own:
- Client-level results over time: AR days, clean claim rate and denial or deduction rate before and after the vendor took over, for every client, not selected case studies.
- Revenue per employee: rising means productivity or pricing is improving; flat under a growing top line means the business is only adding seats.
- Attrition, costed: the vendor should know what it spends to recruit, train and ramp each replacement, and multiply it by the number who left. Few do.
- Revenue by service line: routine work such as payment posting and basic submission is re-pricing fastest; documentation, complex coding and outcome-priced denial work hold value.
What to do this quarter
- Build a one-page monthly report with all seven indicators, split by payer group. If the data does not exist, that is the first finding.
- Pick the payer with the worst combination of AR days and deduction rate, and review fifty of its recent files line by line. The causes are usually few and repetitive.
- Set targets in the same units you will hold a vendor to. "Improve collections" is not a target; "cut TPA deductions from 11% to 7% of claimed amount within two quarters" is.
- Tie these numbers into the monthly finance review, not a separate billing meeting. This is part of FP&A, and it belongs next to the P&L.
The hospitals that manage these seven numbers well do not usually have better software than their peers. They have a CFO who asks for them every month, by payer, and does not accept an average.
