Insurance panel drop order: net per clinical hour, denial drag, and days to money

Which panel should you drop first?

The one that returns the least per clinical hour after you subtract what it costs to collect and how long it holds the money. That ranking already sits in the files the practice receives each week: the electronic remittance a payer sends with each payment, the 835. Nothing published can produce it. A national average allowed amount belongs to no practice in particular, and a benchmark denial rate says nothing about which of your claims came back.

Three numbers do the sorting. Net per clinical hour is what a payer paid, divided by the hours of your time its patients occupied. Denial drag is what those dollars cost to chase. Days to money is the lag between the visit and the deposit, the part the practice finances itself.

None of the three is a number you can look up. Each is a fact about one practice: its codes, its contracts, its patients, its state. A dental practice ranking which PPO to drop first runs the same three columns against a different fee schedule and gets a different answer for the same reason.

Rank the panels and the bottom of the list is a candidate rather than a decision. Contract notice periods, the patients who would have to be told, and the referral flow a panel carries all sit outside the arithmetic, and they are the owner's to weigh.

Read the group code before counting a single denial

A remittance line that pays less than you billed is not automatically a denial, and the field that tells you which it is sits one column to the left. X12 publishes four Claim Adjustment Group Codes, and they classify who bears the adjustment 1Ref 1ASC X12 (Accredited Standards Committee X12) (2026).Claim Adjustment Group Codes.That four Claim Adjustment Group Codes classify who bears a payment adjustment, which is how the article separates a contractual write-off (CO) and patient responsibility (PR) from the payer-initiated and other reductions (PI, OA) that belong in the denial-drag count.. CO marks a contractual obligation, the payer applying the rate you agreed to. PR marks patient responsibility. Count either as a denial and the ranking breaks.

Alongside it, the reason code states why a line was paid differently than it was billed 2Ref 2X12 (2026).Claim Adjustment Reason Codes.That the reason code is the standard field stating why a claim or service line was paid differently than it was billed, and that the list is public, which is the lookup step behind sorting denials by payer and by reason.. X12 keeps that list public, so a code on your remittances gets looked up instead of guessed at, and the counts you build show which reasons cost the most at which payer.

The remark column adds detail and holds two different things. Some remarks explain a specific adjustment. Others are general processing notices tied to no adjustment at all 3Ref 3X12 (2026).Remittance Advice Remark Codes.That remark codes come in two kinds, supplemental detail attached to a specific adjustment and informational notices tied to no adjustment at all, so remark volume alone does not measure rework., so a remit crowded with remarks is not automatically full of rework.

Whatever software reads the remittances has to hand back these three columns per line rather than a monthly summary. A practice still buying the stack in order can test that before it signs; one already running something can usually export the line detail even when the dashboard hides it.

Net per clinical hour, computed from what landed

Take the paid amounts on a payer's remittances over a stretch long enough to be dull, twelve months if you have it, and divide by the clinical hours that payer's patients took. Hours rather than visits, because a panel that pays acceptably per visit can pay badly per hour once its patients need the longer code. The denominator is where this calculation usually goes wrong.

Comparing payers gets easier through a number they hold in common. CMS publishes a Physician Fee Schedule search returning the Medicare amount for a code in a given locality 4Ref 4Centers for Medicare & Medicaid Services (2026).Physician Fee Schedule Search.That CMS publishes a public look-up returning the Medicare amount for a CPT/HCPCS code in a given locality, used here only as the common reference for expressing several payers' allowed amounts on one scale. No figure is attributed to it., so each payer's allowed amount for the same code can be written as a percentage of the same reference. A wall of fee schedules becomes one column.

No published figure says what a panel should return per hour in your specialty, on your codes, in your market. The number is a fact about one practice, computed from its own remittances once a year.

But that figure counts only what arrived, and says nothing about what arriving cost.

Denial drag, the number that hides in staff time

Denial drag is what a payer's dollars cost to collect: the claims that come back, the ones needing a corrected submission, the appeals, and money already paid that is later recouped. Sort the reason codes from your remittances by payer and by frequency, and the shape shows up fast. One payer's drag is usually concentrated in two or three codes.

Recoupments deserve their own line. Overpayments a payer decides to reverse do not always arrive as a bill; some are netted against a later remittance, so a deposit shrinks for reasons that live in a different month's claims. A practice that has received the takeback letter knows the arithmetic. Rank on deposits alone and that cost disappears into what looks like a slow week.

Time the rework rather than look it up. No dependable published figure for staff minutes per denied claim transfers to a practice of one, and it matters here only as a comparison between your own payers. Two weeks of timing, written down as it happens, gives a per-code minute figure good enough to rank with.

Drag also has a shape. A payer whose denials cluster in one reason code may be describing a form problem the practice can fix in an afternoon, and that drag will not survive the fix. Denials spread across many reasons describe a policy posture, and that one tends to hold.

Days to money, set partly by statute and partly by contract

Days to money is the lag from the date of service to the deposit, and part of it is set by law. State prompt-pay statutes give a payer a fixed window to pay a clean claim or to contest it in writing, and many attach interest when the window is missed. The windows differ by state, so this one gets looked up where the practice bills.

New York gives a payer 30 days to pay or contest a claim submitted electronically, and 45 days when it arrives on paper or by fax 5Ref 5New York State Legislature (2026).Insurance Law § 3224-a. Standards for prompt, fair and equitable settlement of claims for health care and payments for health care services.New York's own payment clock, 30 days for an electronically submitted claim and 45 days for paper or fax, and its late-payment interest at the greater of the state corporate tax rate or 12 percent a year, given as one state example of the days-to-money variable.. Miss the window and interest runs at the greater of the state corporate tax rate or 12 percent a year 5Ref 5New York State Legislature (2026).Insurance Law § 3224-a.

California runs a single clock. An uncontested complete claim is due as soon as practicable and no later than 30 calendar days after the insurer receives it, with written notice inside the same window if the claim is contested or denied 6Ref 6California State Legislature (2026).Insurance Code § 10123.13.California's own payment clock, 30 calendar days after receipt for an uncontested complete claim with written contest or denial notice inside the same window, and interest at 15 percent a year from the first calendar day after it closes, given as the contrasting state example.. Late payment carries interest at 15 percent a year, beginning the first calendar day after that window closes 6Ref 6California State Legislature (2026).Insurance Code § 10123.13.California's own payment clock, 30 calendar days after receipt for an uncontested complete claim with written contest or denial notice inside the same window, and interest at 15 percent a year from the first calendar day after it closes, given as the contrasting state example..

Same claim, same submission date, two states, two clocks and two penalty rates. A colleague's number from elsewhere will not transfer, because the clock that binds is the one in your own state's code.

Two limits sit on top of that. Statutory interest penalizes a late payer, and it finances nothing in the meantime, so a chronically slow contract costs the practice its own cash long before any penalty accrues. And these are insurance statutes, reaching the payer through the insurance product; whether a self-funded employer plan administered by the same carrier sits under the same clock is a question for counsel rather than an assumption to rank on.

Putting the three numbers in one order

Build one row per payer with four columns: net per clinical hour, the share of that payer's lines that counted as denials after the group-code sort, the minutes those cost, and the median days from submission to deposit. Sort ascending on net per hour, then move any payer up the drop list whose drag or lag is bad enough to change the order. The top of that list is the first candidate.

A candidate is a place to start reading the contract. The termination clause sets the earliest date a decision can take effect, and some contracts run that clock from an anniversary rather than from the day the letter is sent, which can push an exit most of a year out.

Volume is the other correction. A panel carrying a large share of the schedule takes its patients with it, and the year after a termination usually runs thinner than the year before. That is the de-paneling year, and it is a cash-flow problem to plan for on the way in.

Where the terms are unclear, or the panel fills a large share of revenue, put the contract in front of a health care attorney with the ranking attached, so the conversation starts at consequences instead of arithmetic. The tax side belongs with your accountant in the same week.

Recompute the ranking once a year. Fee schedules move, a payer's denial pattern changes with a policy update, and the panel ranking last this year may not be the one ranking last when the next contract amendment lands.
