Why revenue missed forecast

A revenue miss is rarely one thing. This build uses an invented clinic network. It splits the gap into five causes that add exactly to the total, so volume is never mistaken for price, and it writes the explanation from the numbers.

What this shows

  • Five causes of the gap that add exactly to the total
  • A change in what one billing code pays, and the size of its effect
  • A drill from the network to a clinic to a billing code
  • Commentary written from the numbers, ranked by size

How I use it

  • Closing the month: finding the one or two lines behind most of a miss
  • Telling price from volume before anyone reacts
  • Writing the variance note so the text and the data agree

Sample build: why a clinic network missed its revenue forecast

An invented network of four clinics, billing five remote monitoring and care management codes for one month. Revenue came in under forecast. The bridge splits the gap into five causes that add exactly to it. A new fee schedule raises the rate for one code a lot and trims another. Drill from the network to a clinic to a billing code, and read the explanation the numbers write.

Invented network and numbers for illustration. Rates are rounded and illustrative, not the fee schedule.

What to try

  • Press Without the fee change. The miss grows, because the new rate was covering part of it.
  • Click East clinic. At the starting figures its miss is timing, which should post next month.
  • Set the East share posted to 90 percent. The timing bar disappears.
  • Split the network by billing code. The price change sits in two codes.
  • Click North clinic, then Device supply. One code, three causes.

Visits
More or fewer visits than forecast. A visit is one patient with a check-in in the month.
Code mix
A different number of units of each code billed per visit. Fewer added-time blocks per visit lowers revenue even when visits hold.
Price paid
A different rate paid for each unit. A fee schedule change lands here.
Share collected
A different share of the allowed amount actually paid, after denials and write-offs.
Timing
A different share of the month's collections posted before the month closed. The rest posts next month, so this gap should reverse.

Commentary: the network

Written from the numbers above, largest cause first. It rewrites itself when you change the selection or the levers.

Revenue for the network was $234,835.20 against a forecast of $245,430.00, a miss of $10,594.80 (4.3%).

  1. Price paid added $21,022.74 (8.6% of forecast): higher rates were paid per unit. The biggest source was North clinic (+$8,767.44).
  2. Timing took off $8,901.90 (3.6% of forecast): more collections slipped past the month end than forecast, and they should post next month. The biggest source was East clinic (-$8,901.90).
  3. Visits took off $8,181.00 (3.3% of forecast): fewer visits than forecast. The biggest source was South clinic (-$9,817.20).
  4. Share collected took off $7,607.52 (3.1% of forecast): a smaller share of the allowed amount was collected. The biggest source was North clinic (-$6,873.12).
  5. Code mix took off $6,927.12 (2.8% of forecast): fewer units were billed per visit than forecast. The biggest source was West clinic (-$4,082.40).

Causes that lowered revenue total $31,617.54. Causes that raised it total $21,022.74.

Timing should reverse next month. Leaving it out, revenue is $1,692.90 below forecast.

The forecast used one set of assumptions for every clinic, built on last year's rates. The actual month differs in the places marked below. In this invented case the payer's new fee schedule raised the rate for the first 20 minutes of treatment management a lot and trimmed the rate for device supply a little. Neither is a real rate change, and the rates are rounded and illustrative, not the fee schedule. A visit is one patient with a check-in in the month.
