Deductibles, copays, coinsurance, and patient balances

Patient responsibility is the portion of an allowed amount the patient owes: deductible, copay, or coinsurance. It arrives on the 835 under group code PR, and in most practices it is now one of the largest single sources of revenue, and the hardest to collect.

​

The three forms of cost-sharing

Plus non-covered services (CARC 96, 204), which the patient may owe depending on your contract and whether you obtained proper advance notice.

​

Why patient AR became a top-tier payer

High-deductible health plans shifted a large share of cost onto patients. The consequence for practices is structural:

• A meaningful fraction of your revenue is owed by thousands of individuals rather than a handful of institutions
• Collection rates on patient balances are far lower than on payer balances, and they fall sharply the longer the balance ages
• The cost to collect per dollar is much higher, statements, calls, payment plans
• The deductible season effect: early in the plan year, most patients are pre-deductible, so payer payments drop and patient balances spike. This is a cash-flow pattern to forecast, not a surprise to absorb. See Working capital and AR lending.

​

Estimating at the point of care

The single highest-leverage collection practice, because money collected before the patient leaves is money you don’t chase for ninety days.

​

Balance billing and its limits

Balance billing means billing a patient for the difference between your charge and the allowed amount. For in-network care, your participation agreement prohibits it. The contractual adjustment (CO-45) is your write-off, full stop. Billing a patient for a CO amount is a contract breach and, in many states, a regulatory violation. For out-of-network care, balance billing was historically permitted, and the No Surprises Act (Consolidated Appropriations Act, 2021) sharply restricted it in specified circumstances, notably emergency services and non-emergency services delivered by out-of-network providers at in-network facilities. Where it applies, the patient’s cost-sharing is limited to in-network levels and the provider resolves the balance with the plan through an independent dispute resolution process rather than with the patient.¹ The Act also requires good faith estimates for uninsured and self-pay patients. See The No Surprises Act, briefly.

​

Financial policy

Write one, have patients sign it, and enforce it consistently. It should cover:

• When payment is due, at service, on statement, or per a plan
• Accepted payment methods and card-on-file authorization
• Payment plan terms and eligibility
• The no-show and late-cancellation policy, and its fee
• What happens to balances that age past a stated threshold
• Financial hardship and charity care, if you offer it
• Self-pay pricing and good faith estimates

A signed financial policy is also your best evidence in a chargeback representment. See Prevent chargebacks.

​

Collecting what’s owed

Two mechanics that move collection rates more than anything else: Text-to-pay and e-statements. Paper statements have poor response rates and cost real money per cycle. Digital delivery with a one-tap payment link performs dramatically better. Statement timing. Send within days of adjudication. A statement arriving six weeks after the visit gets treated as a mistake.

​

The collections decision

Sending patients to collections recovers a modest fraction of balances and carries genuine reputational cost — online reviews, community standing, and the ethical weight of pursuing medical debt. Weigh:

• Balance size, small balances rarely justify it
• Whether the patient was offered a plan and declined
• Whether hardship was assessed
• Your community position

Also note the regulatory environment for medical debt reporting has been in flux, with federal and state action on whether and how medical debt appears on consumer credit reports. Verify the current rules before relying on credit reporting as leverage. See Use collections agencies (carefully).

​

MSO-PC note

Patient collection is administrative and squarely an MSO function — statements, calls, payment plans, and processing. Two boundaries:

1. The money is the PC’s. Patient payments are practice revenue and land in the PC’s account, same as payer money. See Structure accounts across your entities.
2. Policy should be PC-approved. Financial policy affects the patient relationship and, at the margin, access to care. The PC should approve it even though the MSO executes it.
