Where revenue leaks out of a medical practice

When a practice tells us collections are down, the first instinct is usually to blame the payor. Occasionally that is right. Far more often the money is being lost inside the building, in five places that are easy to normalise because each one only costs a little.

1. Charge lag

Charge lag is the interval between the date of service and the date the claim leaves your practice. It is the single most controllable number in the revenue cycle and the one most practices never measure. A claim that sits for fourteen days is fourteen days of cash you will not see until next month, and a patient whose coverage may have changed in the meantime.

The fix is rarely more staff. It is a documented daily rhythm: encounters close the same day, charges post within twenty-four hours, and anything that cannot be coded today gets a reason and a name against it.

2. Undercoding

Physicians code defensively. After an audit, or a story from a colleague, it is tempting to downcode everything and avoid attention. The result is legitimate revenue left on the table, month after month, in a practice that is doing the work and documenting it.

Undercoding is not a compliance strategy. It is a revenue problem with a compliance-shaped justification. The honest fix is documentation support and periodic internal review, so the code reflects the note rather than the physician's mood.

3. Denial churn

Most denials are preventable and most preventable denials recur. A missing modifier, an eligibility gap, a registration error — the claim is denied, appealed, paid, and then the same error happens again next week because nobody traced it back to the source.

• Log every denial by reason code, not just by dollar amount.
• Assign each recurring reason to the person who can stop it upstream.
• Review the top three reasons monthly, and retire them one at a time.

4. Aged A/R

Every practice has an A/R bucket past ninety days that everyone knows about and nobody works. It is unattractive work: the claims are old, the payors are unhelpful, and the return per hour is worse than on fresh claims. Which is exactly why it sits there, and exactly why it is worth a scheduled, protected block of time each month.

5. Patient balances

Statements get sent once. Nobody follows up. The balance is small enough that pursuing it feels petty and large enough that, multiplied across a year, it matters.

The structural answer is to collect at the point of care where possible, set a clear financial policy, and use a consistent statement cycle with a defined escalation path. The behavioural answer is to stop treating patient balances as an afterthought in the last ten minutes of the month.

What to measure

Five numbers, reviewed monthly, will tell you whether the cycle is healthy: charge lag in days, first-pass clean claim rate, days in A/R, denial rate by reason, and net collection rate. If those five move in the right direction, the rest of the cycle usually follows.

The most common cause of declining collections is not a payor policy change. It is a process that stopped being watched.
