The allowed amount is the most a health plan will pay for a covered service, counting both the insurer's payment and what the patient owes. For in-network care it comes from your contract with the payer, and for Medicare from its fee schedule, not from what your practice charges. Whatever you bill above it, an in-network practice writes off.
What is the Allowed Amount?
The allowed amount, also known as the allowable charge or negotiated rate, is the maximum a health plan will pay for a specific covered service. For in-network care, it is set in the contract between the insurer and the provider. Government programs such as Medicare set it through their own fee schedules. The allowed amount covers the whole payment for the service: the insurer’s share plus whatever the patient owes in deductible, copay, or coinsurance.
Importance of the Allowed Amount
For your practice, the allowed amount is the number that matters, not your charge. It is what you can actually collect for a service, so it is what to budget on and what to check each payment against.
It also sets the patient's bill. The deductible, copay and coinsurance are worked out from the allowed amount, so a patient balance calculated from your full charge will be wrong.
Factors Influencing the Allowed Amount
Several factors contribute to determining the allowed amount for a particular medical service. These include:
- Insurance Plan Coverage: Different insurance plans offer varying levels of coverage for medical services. The allowed amount is influenced by the specific terms and provisions outlined in the patient’s insurance policy.
- Provider Contracts: Healthcare providers enter into contracts with insurance companies, establishing the rates at which services will be reimbursed. These negotiated rates, which often represent a discounted fee schedule, form the basis for the allowed amount.
- Fee Schedules: Insurance companies may maintain fee schedules that outline the maximum allowable charges for specific procedures. Providers are typically reimbursed based on these predefined rates, subject to contractual agreements.
- Geographic Location: Rates vary by region. Medicare adjusts its fee schedule by location, and providers in higher-cost areas may negotiate higher rates with commercial plans.
How the Allowed Amount Is Split
The allowed amount itself comes from the payer’s contract or fee schedule, not from the provider’s bill. Once it is set, several components determine who pays what: the billed amount, deductible, coinsurance, and copayments. Here’s a breakdown of the key elements:
- Billed Amount: This represents the total charge for the medical service rendered by the healthcare provider. The payer compares it with the allowed amount and generally pays based on the lower of the two.
- Deductible: The deductible is the amount the patient must pay out-of-pocket before their insurance coverage begins. Once the deductible is met, the insurance company will typically cover a percentage of the remaining costs.
- Coinsurance: Coinsurance refers to the portion of the medical expenses the patient is responsible for paying after the deductible has been satisfied. It is usually expressed as a percentage, with the insurance company covering the remaining percentage.
- Copayments: Copayments are fixed amounts that patients must pay for certain services, such as office visits or prescription medications. These payments are separate from deductibles and coinsurance and are typically established in the insurance policy.
The patient’s deductible, coinsurance, and copayments are worked out from the allowed amount, and the insurance company pays the rest of it. For example, if a provider bills $200, the allowed amount is $120, and the patient has met the deductible and owes 20% coinsurance, the patient pays $24, the insurer pays $96, and an in-network provider writes off the remaining $80 as a contractual adjustment.
Where You See It on a Remittance
The payer's remittance, an ERA or an EOB, shows each step of that split as an adjustment with a reason code from the X12 claim adjustment reason code list. In the example above, the $80 write-off appears under code 45 ("Charge exceeds fee schedule/maximum allowable or contracted/legislated fee arrangement") with group code CO, a contractual obligation the practice absorbs. The patient's share appears under group code PR (patient responsibility), with code 1 for a deductible, 2 for coinsurance or 3 for a copay.
Billed Amount vs. Allowed Amount
It’s essential to distinguish between the billed amount and the allowed amount, as they serve distinct purposes in the medical billing process:
- Billed Amount: This is the total charge submitted by the healthcare provider for the services rendered. It reflects the standard rates for the services provided without consideration for insurance contracts or negotiated rates.
- Allowed Amount: The allowed amount, on the other hand, represents the maximum reimbursement the insurance company will provide for the covered services. It is determined based on contractual agreements between the insurer and the healthcare provider, often resulting in a discounted rate from the billed amount.
Implications for Patients
In-network providers agree not to bill patients for more than the allowed amount, so the patient owes only the deductible, coinsurance, or copayment. With an out-of-network provider, if the billed amount exceeds the allowed amount, patients may be responsible for paying the difference out-of-pocket (balance billing) on top of any deductibles, coinsurance, or copayments, although the federal No Surprises Act protects patients from balance bills for most emergency care and for certain out-of-network care at in-network facilities.
For your front desk, that means a patient's estimate should start from the allowed amount for their plan, and an in-network patient should never be billed the difference between your charge and the allowed amount.
Implications for Healthcare Providers
A payer can pay less than your contract allows, by mistake or after a fee schedule change, and the remittance won't say so. If the difference is written off as a contractual adjustment, nobody notices. Common slips:
- Posting every adjustment as contractual without checking the allowed amount against the contract.
- Billing the patient for the write-off on an in-network claim.
- Calculating the patient's share from the charge rather than the allowed amount.
- Not loading updated fee schedules into the billing system when contracts renew.
A short checklist for your billing team:
- Keep each major payer's fee schedule for your common codes in your billing system.
- When posting, compare the allowed amount on the remittance with the contracted rate.
- Send underpaid lines back to the payer, with the contract as support.
- Look for underpayments that repeat for one payer or one code; they usually have one cause.
