Here's how to model that risk before it drains your practice's cash. - Author: Human Business Works - Tags: healthcare, billing, cashflow, practice, finance-funding ## The Gap Between Seeing a Patient and Getting Paid A new practice owner sees patients steadily for the first two months. The schedule fills up, the front desk is busy, and the clinical work feels like it's going well. Then the owner checks the bank account and finds barely enough to cover payroll. Nothing about the clinical side went wrong. What went wrong is that the money for those first two months of visits hasn't arrived yet, and won't for weeks. This is the part of opening or expanding a practice that rarely gets modeled with any precision before the doors open. Everyone accounts for rent, equipment, staffing, and malpractice coverage. Far fewer people sit down and map out exactly how long cash takes to move from a patient encounter to a deposited payment, and how much of that money gets lost or delayed along the way. ## The Billing Cycle Has More Steps Than It Looks The basic mechanics: a patient is seen, the visit is coded, a claim is submitted to the payer, the payer adjudicates the claim, and eventually a payment (or a denial) comes back. On paper that's four or five steps. In practice, each step has its own timeline, and each timeline can stretch. Coding and claim submission usually happen within a few days of the visit if a practice is disciplined about it. New practices, though, are often still training staff, testing a new EHR, or working through a billing backlog, so claims can sit uncoded for a week or two without anyone noticing. Once a clean claim reaches a payer, adjudication typically takes somewhere between two and six weeks, depending on the payer and whether the claim requires manual review. Government payers like Medicare tend to have statutory processing windows; commercial payers vary more, and some build slower turnaround directly into their contracts. Add in that many practices submit claims in batches rather than daily, and the real average time from visit to first payment attempt is often 30 to 45 days even when nothing goes wrong. ## Denials and the Resubmission Clock Something going wrong is common. Claim denial rates across the industry are frequently cited in the range of 5 to 15 percent of first submissions, depending on specialty, payer mix, and coding accuracy. A denial doesn't just delay payment by a few days. It restarts a large part of the process. A denied claim has to be reviewed, corrected if the error is on the practice's side, and resubmitted. Many payers require resubmission within a defined window, often 90 to 180 days from the original denial, but the practical cost isn't the deadline itself. It's that the corrected claim goes back into the same adjudication queue and takes another two to six weeks to process. A claim denied on day 30 and resubmitted on day 40 might not see payment until day 70 or 80\. If it's denied a second time for a different reason, which happens more often than most new owners expect, the timeline extends again. Appeals for claims denied on medical necessity or coverage grounds take longer still, sometimes months, and often require documentation that eats staff time regardless of the outcome. None of this shows up in a simple revenue projection. It shows up in the bank account. ## Payer Contract Terms Set the Real Timeline The contract a practice signs with each payer determines a lot of this timeline before a single patient walks in. Contracts specify allowed reimbursement rates, timely filing limits, and sometimes the payer's own processing commitments. What they rarely specify, at least in plain language, is how aggressively that payer denies claims on first submission or how slow its appeals process runs in practice. This is information most new practice owners don't have, because they haven't billed that payer before. Practices that have been operating for years develop an informal sense of which payers pay in three weeks and which take three months, and they price their cash flow planning accordingly. A practice opening its doors for the first time is negotiating contracts blind on this dimension, which is one reason the first six months often produce the tightest cash position a practice will ever face. ## Modeling Your Own Reimbursement Risk Before opening or expanding, it's worth building a simple model rather than relying on a general sense that "insurance pays slowly." The inputs are: - Average days from visit to claim submission, based on realistic staff capacity, not best-case - Average payer adjudication time for each major payer in the expected mix - Expected first-pass denial rate, weighted by payer - Average time from denial to resubmission, and resubmission to payment - Percentage of revenue expected from self-pay or point-of-service collection, which arrives immediately and offsets the gap Running these numbers produces a weighted average collection period, often 45 to 90 days for a new practice with an unproven payer mix, sometimes longer. That number, multiplied by average monthly operating expenses, gives a rough estimate of the minimum cash reserve or credit access needed to survive the ramp-up period without missing payroll or rent. Practices that skip this exercise tend to find out the number the hard way, which is a pattern closely related to how [a solo medical practice outgrows the person who built it](https://human-business-works.ghost.io/solo-medical-practice-outgrows-owner/): the same owner absorbing every operational shock has less slack left to absorb a cash timing problem too. ## Bridging the Gap: Credit or Outsourcing Once the gap is quantified, practices generally choose between two tools, or some mix of both. A line of credit is the more common default. It's flexible and doesn't require handing billing to an outside party, but it carries interest costs that compound if the practice draws on it repeatedly during a slow reimbursement stretch rather than as a one-time bridge. Lenders also want to see receivables aging reports, which means the practice needs decent billing visibility just to qualify for the credit meant to cover billing delays. Outsourcing billing to a third-party service is the other common route. These services typically charge a percentage of collections, often somewhere between 4 and 9 percent, rather than a flat fee. The tradeoff is real: the practice gives up a slice of every dollar collected, but often gets faster claim submission, lower denial rates from experienced coders, and more consistent follow-up on aging claims. For a new practice without the staff or systems to manage billing well internally, the percentage fee can cost less than the interest and stress of financing a self-inflicted cash gap. Neither choice eliminates the underlying timeline. What they do is change who absorbs the float, and at what price, while the claims work their way through the system at their own pace. The practical takeaway for anyone opening or expanding a practice is to treat the reimbursement timeline as a financing decision, not a billing detail. Model it before signing a lease, not after the first slow month shows up in the bank statement.
