Medicaid reimbursements create a bookkeeping challenge that most practice management systems don’t solve on their own. The lag between filing a claim and receiving payment averages 30 to 90 days, and some claims take considerably longer. If your books don’t account for this properly, your revenue looks inflated and your cash position looks better than it actually is.

The first thing to get right is recording claims at the expected reimbursement amount rather than your billed charges. Medicaid pays a contracted rate that’s almost always lower than what you bill. The difference between your standard fee and the Medicaid-allowed amount is a contractual adjustment, not real revenue. If you book a $200 procedure at $200 but Medicaid only pays $85, carrying $200 in accounts receivable misrepresents your financial picture. Record the $85 as expected revenue and post the $115 contractual adjustment immediately. This keeps your A/R honest and your revenue reports meaningful.

Separate your Medicaid receivables from commercial insurance receivables in your accounting system. This is not optional if you want usable cash flow projections. Commercial claims might pay in 14 to 30 days. Medicaid takes two to three times longer. When these are lumped together in one A/R bucket, your aging report tells you very little. You can’t distinguish between a commercial claim that’s overdue and needs follow-up and a Medicaid claim that’s simply moving through normal processing timelines.

Run your Medicaid aging report weekly or at minimum every two weeks. Claims sitting at 45 days might be normal. Claims sitting at 90 days probably need attention. Claims beyond 120 days are likely heading toward denial or have already been denied without your team catching it. The aging report by payer type tells you where to focus your follow-up efforts and how much of your outstanding A/R is actually collectible.

When claims get denied, don’t write them off immediately. File your appeals and track the status. Most practices have a window to appeal, and a meaningful percentage of initial denials get overturned with proper documentation. In your books, keep denied-under-appeal claims in a separate category or tag them so you know the difference between a clean claim waiting for payment and a claim you’re fighting for. Once you’ve exhausted the appeals process and the denial is final, write it off as a bad debt or adjustment. Tracking these write-offs by denial reason over time shows you patterns that might be fixable, like missing documentation or coding errors.

Cash flow forecasting for medical and dental practices that accept Medicaid requires looking at your payer mix closely. If 40% of your revenue comes from Medicaid, you need to plan for the reality that a large chunk of any given month’s production won’t convert to cash for two or three months. That means your operating expenses for the next 60 to 90 days need to be covered by collections from work you already did, not work you’re doing now. Practices that don’t plan for this end up short on payroll or scrambling to cover supply orders.

Getting this right takes discipline in how claims are entered, categorized, and followed up on. Many practice owners we work with as Phoenix bookkeepers inherited a system where everything was booked at billed charges with adjustments only posted when payments arrived. That approach makes it impossible to know your real revenue or real receivables at any point during the month. Cleaning this up and building a process that tracks Medicaid separately gives you financial data you can actually make decisions with.
