Cost to collect

Write the formula before gathering data

One management formula is:

Cost to collect percentage = defined collection costs ÷ cash collected × 100

Another organization may use net patient service revenue, adjusted collections, or a mature service cohort. Each denominator answers a different question. Label it explicitly.

Define entity, locations, payers, service dates, cash dates, accounting basis, period, maturity window, adjustments, refunds, recoupments, patient collections, and intercompany activity. Keep the formula stable across comparison periods.

Build a complete numerator

Possible costs include billing and follow-up labor, payroll burden, coding review, credentialing work allocated by policy, clearinghouse and transaction fees, RCM software, payment processing, postage, lockbox, vendor fees, audit support, and management oversight.

Include each cost once. A vendor percentage may already cover staff or technology. Shared finance, IT, compliance, and leadership costs need a documented allocation method when included.

Separate one-time implementation, cleanup, acquisition, and project costs from ongoing operations. Show both views when leaders need them.

Match cost timing with the denominator

Current-month cash can come from services delivered many months earlier. Current-month RCM labor may work on newer or older accounts. A simple calendar ratio blends those periods.

For trend reporting, use a consistent calendar method and disclose the lag. For cohort economics, follow a locked service-date cohort through a defined maturity point and assign costs through an approved method.

Keep immature claims, holds, appeals, and payment plans visible. Excluding difficult work can make the ratio look cheaper while cash remains unresolved.

Distinguish remittance from cash

CMS explains that an electronic remittance advice explains claim-payment results and adjustments, while electronic funds transfer moves money. They can arrive separately.

Count cash under the selected bank and accounting rule. Reassociate deposits with remittances and claims before reporting collection detail. A posted ERA balance is not automatically cash received.

Track refunds and recoupments consistently. State whether they reduce collections, increase cost, or appear in a separate reconciliation line.

A fictional four-percent calculation

Fieldstone ABA defines monthly collection cost as internal RCM labor and burden, vendor fees, clearinghouse charges, payment processing, and allocated RCM management. The total is $58,000.

Cash collected under its stated policy is $1,450,000. The percentage is $58,000 ÷ $1,450,000 × 100 = 4.0% for the month.

Fieldstone also calculates a separate service-cohort view after twelve months. It never mixes that denominator with the calendar-month numerator or presents the two percentages as directly comparable.

Lower cost can carry hidden tradeoffs

A lower ratio may reflect automation, clean intake, timely documentation, accurate claims, or an effective vendor. It may also reflect understaffing, delayed follow-up, weak appeals, unposted cash, or excluded costs.

Pair the ratio with net collection rate, denial rate, first-pass acceptance, days in accounts receivable, aged balances, credit balances, appeal yield, payment-posting lag, complaint volume, staff workload, and compliance findings.

Keep clinical authorship and coding decisions with qualified roles. Financial pressure offers no authority to alter clinical records, services, dates, units, or rationale.

Govern source data and allocations

The IRS transaction-recording page emphasizes complete and accurate records. Reconcile payroll, invoices, vendor reports, bank deposits, remittances, and general-ledger accounts before calculation.

The SBA finance page stresses bookkeeping and cash-flow management. Version the policy, assign each line an owner, and document every allocation.

Useful control measures include numerator accounts reconciled divided by accounts due, deposits matched divided by deposits due, and cost allocations reviewed by target divided by allocations due. Report late work and exceptions beside the ratio.

Build a cost allocation map

List every revenue-cycle role, vendor, system, transaction fee, mailing stream, bank service, management function, and shared department that may enter the numerator. For each item, record the ledger account, owner, inclusion decision, allocation driver, period, and source.

Choose allocation drivers that match use. Headcount, logged time, claim volume, transactions, or direct assignment can produce different results. Document the reason and test sensitivity to another plausible driver.

Reconcile the map to the general ledger and vendor invoices. Flag costs that another fee already includes. Keep project work, refunds, payer recoupments, patient refunds, and bad debt in separate rows until the approved policy determines treatment.

When an RCM vendor changes, preserve the old and new scopes. Compare like services directly and account for transition work, implementation fees, internal oversight, and work retained by the practice.

Release the ratio only when scope, period, numerator, denominator, timing, allocations, and reconciliations are reproducible. Then choose an operational action from the paired quality measures. A lower percentage should never justify suppressed follow-up, altered clinical records, late refunds, or an understaffed revenue cycle.
