Billing Audit Checklist for Women’s Health Practices

A billing audit checklist is not just a back-office task. For a midwifery practice, birth center, lactation practice, or OB/GYN office, it is one of the clearest ways to find the small breakdowns that turn completed care into delayed or lost revenue. A missing authorization, an outdated payer rule, or a charge entered under the wrong provider can create weeks of follow-up and unnecessary patient confusion.

The goal of an audit is not to search for blame. It is to confirm that your workflow supports clean claims, accurate patient balances, and timely reimbursement from the first verification of benefits through payment posting. The most effective audits look at both individual claims and the process that produced them.

Start Your Billing Audit Checklist With the Right Sample

Reviewing every claim at once can overwhelm a small practice. Start with a focused sample: recently paid claims, denied claims, claims still open after 30 days, and high-dollar maternity or facility claims. If your volume is low, review every claim for a defined period. If your volume is higher, select a representative sample from each payer and service line.

Your sample should include the services that create the most financial risk for your practice. For a birth center, that may include global maternity care, facility billing, newborn-related services, or claims with multiple providers. For lactation consultants, it may mean reviewing payer-specific coverage requirements and documentation tied to medical necessity. An OB/GYN practice may need to look closely at global versus non-global billing, surgical claims, and modifier use.

As you review, document patterns rather than treating each error as isolated. Three claims with the same missing modifier are not three separate mistakes. They are evidence that a template, training process, charge entry rule, or EMR workflow needs attention.

Billing Audit Checklist: Review Each Step of the Revenue Cycle

Verify patient and insurance information

Confirm that the patient’s demographic information matches the insurance card and eligibility record. Check the spelling of the name, date of birth, subscriber ID, group number, relationship to subscriber, and current address. Small discrepancies can cause avoidable rejections before a payer ever evaluates the claim.

Then review the verification of benefits, or VOB. The VOB should show active coverage on the date of service, network status, deductible and coinsurance details, authorization or referral requirements, visit limits, and any exclusions that affect the planned care. For maternity services, confirm whether the payer recognizes the provider type and setting. Coverage for a midwife, doula, birth center, or lactation service can depend heavily on the plan, state rules, and network arrangement.

A VOB is a snapshot, not a guarantee of payment. Still, a thorough VOB gives your team a documented basis for financial discussions and helps prevent claims from being submitted with an incorrect assumption about benefits.

Confirm credentialing, enrollment, and billing entities

A clean claim can still deny when the provider is not properly credentialed, enrolled, or linked to the correct billing entity. Review the rendering provider, billing provider, taxonomy, NPI, Tax ID, and service location on submitted claims. These fields must align with the payer’s enrollment records.

This step is especially important for group practices, birth centers, and providers who work across multiple locations. A provider may be credentialed individually but not enrolled under the group contract, or a facility may be recognized by one payer but not another. Do not assume a prior payment confirms everything is correct. Payer systems change, contracts renew, and enrollment records can become outdated.

Keep credentialing status visible to the billing team. When a new clinician joins, changes locations, or begins seeing patients under a new entity, billing should be involved before the first insurance claim is filed.

Match documentation, codes, and charges

Audit whether the medical record supports every diagnosis code, procedure code, modifier, unit, and date of service billed. The documentation should tell the same story as the claim. If a payer reviews the record, there should be a clear connection between the care provided, the diagnosis, and the code submitted.

For women’s health practices, this review often requires attention to global maternity billing rules. Determine whether the patient’s care meets the payer’s requirements for global billing or whether services should be billed separately due to transfer of care, pregnancy loss, late entry to care, or another exception. The answer depends on the payer contract and the actual care delivered. Using a global code because it feels administratively simpler can create recoupment risk if the documentation does not support it.

Check modifiers with the same care. Modifiers can be necessary to clarify distinct services, repeat procedures, assistant roles, professional versus facility components, or other billing circumstances. They should not be added automatically. An unsupported modifier may increase denial risk, while a missing modifier can make a correctly performed service appear duplicative or non-covered.

Review authorization and referral controls

For every service that requires prior authorization, confirm that the authorization was obtained before the service date, applies to the correct provider and location, and includes enough approved visits or units. Also confirm that the authorization number is transmitted accurately on the claim when required.

Referrals deserve the same attention. Some plans require a referral from a primary care provider even when the patient has been seen by your practice before. A referral that is expired, assigned to a different provider, or missing from the payer portal can lead to a denial that your team could have prevented.

Build a clear handoff between scheduling, clinical staff, and billing. Authorization failures often begin at scheduling, but the unpaid claim lands in billing’s queue.

Check claim submission and payer response timing

Look at the claim creation date, submission date, clearinghouse acceptance, payer acceptance, and adjudication date. A claim that sat unsubmitted for a week may not look serious on its own, but repeated delays can push claims closer to timely filing deadlines and slow cash flow.

Review rejections separately from denials. A rejection means the claim did not make it into the payer’s adjudication system, often because of a data or formatting issue. A denial means the payer processed the claim and decided not to pay it as billed. The correction path, appeal rights, and follow-up timeline may be different.

Create ownership rules for every unpaid claim. Someone should know whether the next action is correcting demographic data, submitting records, calling the payer, filing an appeal, billing the patient, or escalating a credentialing issue. Claims without a defined next step are the ones that quietly age out.

Validate payments, adjustments, and patient balances

Payment posting is where you learn whether the claim was paid correctly, not simply whether money arrived. Compare the electronic remittance advice or explanation of benefits against your contracted allowable amount. Verify the payer payment, contractual adjustment, deductible, copay, coinsurance, and any remaining patient responsibility.

Watch for underpayments. They can occur when a payer applies the wrong fee schedule, processes the wrong code, ignores a modifier, or misclassifies the provider or place of service. A small underpayment repeated across dozens of claims can become a meaningful revenue leak.

Patient balances also require careful review. Do not transfer a denied amount to the patient automatically. First confirm whether the denial resulted from a practice error, a payer processing error, a missing authorization, a non-covered service disclosed in advance, or a true patient responsibility under the plan. Accurate billing protects your revenue and your patient relationships.

Turn Audit Findings Into Process Changes

An audit only creates value when the findings change what happens next. Rank issues by financial impact, frequency, and ease of correction. A rare payer glitch may deserve monitoring, while repeated eligibility errors or unworked denials need an immediate workflow fix.

Assign each correction to an owner and set a due date. That may involve updating EMR charge templates, retraining staff on VOB documentation, correcting payer enrollment records, or creating a denial follow-up queue. Re-audit the affected workflow after 30 to 60 days to verify that the correction worked.

As maternity billing requirements continue to change ahead of 2026 and 2027, regular audits become even more valuable. A process that worked last year may not protect reimbursement under a new payer policy or coding requirement. Reviewing claims before revenue problems become a pattern gives your practice more control, less billing stress, and more time to focus on patient care.
