by | Sep 28, 2023

OB/GYN Claim Denials

In healthcare, OB/GYN (Obstetrics and Gynecology) claim denials can be challenging. Let’s explore it by picturing a dedicated healthcare provider, like a physician, who diligently submits a claim to an insurance company, seeking rightful reimbursement for services provided to a patient. However, despite their best efforts, the insurance company denies the claim. These claim denials can occur for various reasons, ranging from seemingly minor coding errors to issues with billing details, incomplete documentation, or even disputes over medical necessity.

If this is the situation, then what will your choice be?

This article will discuss the OB/GYN claim denials and equip you with valuable strategies to sidestep these obstacles. We’ll explore practical approaches to ensure your claims are submitted successfully and approved, helping you navigate the complex medical billing and reimbursement landscape. So, let’s start successfully avoiding OB/GYN claim denials, safeguarding your practice’s financial health and patient care quality.


Most Common Causes For Claims Denials For OB/GYN

Claims denials in Obstetrics and Gynecology (OB/GYN) can be a frustrating and common challenge for healthcare providers. These denials occur when insurance companies reject or refuse to pay for medical services provided to patients. Understanding the most common causes for claims denials in OB/GYN is crucial for healthcare practices to address these issues proactively and improve revenue cycle management.

Here are some of the most prevalent reasons for claims denials in OB/GYN:

1. Coding Errors

Incorrectly assigning medical codes, such as CPT (Current Procedural Terminology) and ICD-10 (International Classification of Diseases, 10th Edition), is a leading cause of claim denials. This may include using outdated codes, coding for services not performed, or failing to include necessary modifiers.

2. Incomplete Documentation

Insufficient or poorly documented patient records can lead to claims denials. It’s vital to provide detailed and accurate documentation of services rendered, including the patient’s medical history, examinations, procedures, and diagnoses.

3. Eligibility and Insurance Verification

To avoid claim denial, please verify a patient’s insurance eligibility and coverage details before providing services. Patients may have lapsed coverage, incorrect insurance information, or limitations on their policies that affect reimbursement.

4. Lack of Prior Authorization

Some procedures and treatments require prior authorization from insurance companies. Failure to obtain the necessary authorization can lead to denials, leaving the provider responsible for the costs.

5. Timeliness – Timely Filling Limit

Insurance companies often have strict deadlines for claim submission. They need to meet these deadlines, whether due to administrative delays or oversight, to avoid denied claims.

6. Coordination of Benefits (COB) Issues

In cases where patients have multiple insurance plans, COB issues can arise. Failing to coordinate benefits between primary and secondary insurers can lead to claim denials.

7. Medical Necessity Disputes

Insurance companies may dispute the medical necessity of certain procedures or treatments. It’s essential to provide clear and well-documented evidence of the medical need for services to prevent denials.


8. Duplicate Claims

Submitting duplicate claims for the same services can trigger denials. Healthcare providers should ensure their billing processes are free from redundancy and errors. 

How To Avoid Common Causes For Claim Denials For OB/GYN?

Indeed, the challenges can be overwhelming for healthcare providers, juggling patient care demands and administrative tasks like accurate billing. This is where specialized medical billing services come into play, offering extensive expertise to streamline the billing process. These services can significantly ease the burden of navigating the complexities of claims submission and denial prevention. By entrusting your billing needs to professionals well-versed in medical coding, documentation requirements, and insurance protocols, you can ensure that your claims are handled accurately and efficiently. This helps to smooth your revenue cycle and allows you to focus more on what matters most – providing high-quality patient care. Collaborating with medical billing experts can be a strategic and valuable decision for OB/GYN practices seeking to optimize their financial operations while maintaining excellence in healthcare delivery.


Best Practices For OB/GYN Coding

Coding for obstetrics and gynecology (OB/GYN) services is critical to healthcare billing and reimbursement. Accurate coding ensures that healthcare providers are appropriately compensated for their services and helps prevent denials. Below, I’ll provide a comprehensive coding guide for OB/GYN, including examples and key best practices.

1. Use the Correct ICD-10-CM Codes for Pregnancy and Related Conditions

    • O Codes: These are used to document pregnancy-related conditions and trimesters. Be sure to use the correct code for the specific trimester.
    • Example: O09.01 – Supervision of pregnancy with a history of infertility, first trimester.
    • 02 – Supervision of pregnancy with a history of infertility, second trimester.
    • 03 – Supervision of pregnancy with a history of infertility, third trimester.
  1. Document Specific Conditions and Complications
    • Ensure accurate documentation of any complications or conditions during pregnancy, such as gestational diabetes, preeclampsia, or fetal anomalies.
    • Example: O24.410 – Gestational diabetes mellitus in pregnancy, first trimester.
  1. Utilize CPT Codes for OB/GYN Services
    • CPT (Current Procedural Terminology) codes report procedures and services.
    • Example: 59400 – Routine obstetric care, including antepartum care, vaginal delivery (with or without episiotomy and forceps), and postpartum care.
  1. Specify the Number of Fetuses
    • If the pregnancy involves multiple fetuses, clearly document this and use appropriate codes.
    • Example: O30.001 – Twin pregnancy, an unspecified number of placenta, and an unspecified number of amniotic sacs, first trimester.
  1. Use Modifier -22 for Increased Procedural Services
    • Modifier -22 is used when a service or procedure requires significantly increased work, complexity, or time compared to the typical procedure. It indicates that the physician has gone above and beyond the usual framework of a particular procedure.
    • Example:If during a cesarean section (CPT code 59510), the OB/GYN encounters unexpected complexities that necessitate additional time or effort, Modifier -22 (e.g., 59510-22) should be appended to the code to indicate increased complexity.
    • Modifier -22 requires proper documentation to support the claim for increased procedural services, including a detailed explanation of why the procedure was more complex or required additional resources. This documentation is crucial for obtaining full provider reimbursement.
  1. Report Ultrasound Codes Accurately
    • Ultrasound codes require specificity regarding the number of fetuses, gestational age, and the purpose of the ultrasound.
    • Example: 76805 – Ultrasound, pregnant uterus, real-time with image documentation, limited or follow-up (e.g., for fetal position, placental location, fetal heart rate), first trimester.
  1. Document Time-Based Services
    • Some OB/GYN services are time-based. Ensure that you document the time spent on these services accurately. Time-based services may require the use of specific codes to reflect the duration of the service provided.
    • Example: For prolonged services in the office or other outpatient settings, use the appropriate codes based on the duration of direct patient contact beyond the usual service. Here are the correct examples:
    • For Medicare Prolonged Services:
      • G2212 x 1 + 99215: 69-83 minutes
      • G2212 x 1 + 99205: 89-103 minutes
      • G2212 x 2 + 99215: 84-98 minutes
      • G2212 x 2 + 99205: 104-118 minutes
      • G2212 x 3 + 99215: >98 minutes
      • G2212 x 3 + 99205: >118 minutes
      • (Add another G2212 for each additional 15 minutes.)
    • For CPT Prolonged Services:
      • 99417 x 1 + 99215: 55-69 minutes
      • 99417 x 1 + 99205: 75-89 minutes
      • 99417 x 2 + 99215: 70-84 minutes
      • 99417 x 2 + 99205: 90-104 minutes
      • 99417 x 3 + 99215: 84 minutes
      • 99417 x 3 + 99205: 104 minutes
      • (Add another 99417 for each additional 15 minutes)
  1. Avoid Unbundling
    • Do not unbundle services by reporting multiple codes when a single, comprehensive code is available.
    • Example: Instead of billing separately for antepartum care, vaginal delivery, and postpartum care, use code 59400 for routine obstetric care.
  1. Stay Current with Coding Changes
    • Regularly update your knowledge of OB/GYN coding guidelines, which may change over time. Utilize resources like the ICD-10-CM and CPT code books or online coding resources.
  1. Document Thoroughly
    • Accurate coding relies on complete and detailed documentation. Ensure the medical record includes all necessary information to support your codes.
  1. Code for Specific Encounters

Use the appropriate code for the type of encounter, such as initial prenatal visit, subsequent prenatal visit, or postpartum visit. Documentation should indicate the purpose of the visit.

    • Use code 0500Fto denote the initial prenatal visit. This code signifies the first prenatal visit in the medical record.
    • Use code 0501Fto indicate that a prenatal flow sheet was documented in the medical record during the first prenatal visit.
    • Utilize code 0502Ffor subsequent prenatal visits. This code reflects ongoing prenatal care beyond the initial visit.
    • Code 0503Fis appropriate for postpartum visits. This code signifies care provided in the postpartum period.
  1. Be Aware of Global Obstetric Packages
    • Some OB/GYN services, such as prenatal care, delivery, and postpartum care, may be bundled into a global obstetric package. Ensure proper coding and billing for these packages.
    • Example: Global obstetric packages typically include antepartum, delivery, and postpartum care. Use the appropriate global OB package code (e.g., 59400) for billing.
  1. Code for Cesarean Sections (C-Sections)
    • If a cesarean section is performed, use the correct CPT code for the surgical procedure.
    • Example: 59510 – Routine obstetric care, including antepartum care, cesarean delivery, and postpartum care.
  1. Understand Diagnosis-Related Groups (DRGs)
    • In hospital settings, reimbursement for obstetric services may be based on DRGs. Ensure accurate coding and documentation to assign the appropriate DRG.
  1. Use NCCI Edits
    • The National Correct Coding Initiative (NCCI) edits identify code pairs that should not be billed together in the same encounter unless specific clinical circumstances justify their use. Always check for NCCI edits when coding.
  1. Stay Informed About Local Coverage Determinations (LCDs)
    • Medicare and other payers may have specific LCDs affecting your region’s coding and billing. Familiarize yourself with these guidelines to ensure compliance.
  1. Update Codes for ICD-10 Changes
    • ICD-10 codes are periodically updated. Stay up-to-date with the latest coding changes and ensure your practice’s electronic health record (EHR) system reflects these updates.
  1. Regularly Audit Coding and Documentation
    • Conduct regular coding and documentation audits to identify errors or inconsistencies. Correct any issues promptly to avoid denials or compliance problems.
  1. Provide Ongoing Training
    • Ensure your coding and billing staff receive continuous training and education to keep their coding skills current.
  1. Seek Expert Consultation
    • If you encounter complex or unusual cases, consider seeking consultation from a certified medical coder or billing specialist with OB/GYN coding expertise.
  1. Understand Payor Policies
    • Different insurance payors may have varying policies and requirements for OB/GYN coding. Be aware of these policies and tailor your coding practices accordingly.

OB/GYN Modifiers Play a Vital Role In Successful OB/GYN Claims

Modifiers are crucial in OB/GYN coding to provide additional information about the services or procedures performed. Here are some common modifiers used in OB/GYN coding:


Modifier -24

(Unrelated Evaluation and Management Service by the Same Physician During a Postoperative Period)

  • Example: A patient recently had a hysterectomy returns for an unrelated issue, such as a urinary tract infection. You would append modifier -24 to the E/M code (e.g., 99212-24) to indicate that it’s unrelated to the previous surgery.

Modifier -25

(Significant, Separately Identifiable Evaluation and Management Service by the Same Physician or other qualified health care professional on the Same Day of the Procedure or Other Service)

  • Example: A patient comes in for a routine prenatal visit (e.g., CPT 99213) but also reports a new health issue that requires additional evaluation and management. In this case, you would append modifier -25 to the E/M code (e.g., 99213-25) to indicate that it’s a separate and significant service.

Modifier -27

(Multiple Outpatient Hospital E/M Encounters on the Same Date)

    • Example: A patient is seen multiple times on the same day in an outpatient hospital setting for various complications related to her pregnancy. You would append modifier -27 to each E/M code to indicate multiple encounters on the same date.

Modifier -57

(Decision for Surgery)

    • Example: During a recent ultrasound, a 2.0 cm left ovarian cyst was discovered in the patient. The patient is experiencing persistent vaginal bleeding with clot passage and has expressed a desire for NovaSure Ablation. The appropriate CPT code for the procedure is 58563.
    • Modifier -57 should be added to the Evaluation and Management (E/M) code used during a prior encounter when the physician examined the patient and decided on the surgical intervention due to these issues to document the decision for surgery properly. Modifier -57 ensures accurate billing and documentation of the surgery decision-making process.

Modifier -59

(Distinct Procedural Service)

    • Example: During a cesarean section (CPT 59510), the surgeon also performs a bilateral salpingectomy for sterilization. You would append modifier -59 to the salpingectomy code (e.g., 58700-59) to indicate that it is a distinct procedural service separate from the cesarean section.

Modifier -80

(Assistant Surgeon)

    • Example: During a complex obstetric surgery, an assistant surgeon assists. You would append modifier -80 to the procedure code (e.g., 59510-80) to indicate the involvement of an assistant surgeon.

Modifier -QW

(To Denote CLIA-Waived Lab Test)

    • Example: A point-of-care pregnancy test is performed in the OB/GYN clinic, and the test is CLIA-waived. You would append modifier -QW to the lab test code (e.g., 81025-QW) to indicate that it’s a CLIA-waived test.

Modifier -XE

(Separate Encounter)

    • Example: A pregnant patient visits the OB/GYN for routine pregnancy monitoring (CPT 59426). Later in the day, the patient returns to the clinic for allergy testing. You would append modifier -XE to the allergy testing code (e.g., 95004-XE) to indicate a separate encounter distinct from the prenatal visit.

Review the Rejection Explanation

    • Carefully review the rejection explanation provided by the payer. It will include a reason code or message explaining why the claim was rejected. Understanding the specific reason for the rejection is crucial for addressing it effectively.

Verify Patient and Provider Information

    • Double-check that all patient information, including demographics and insurance details, is accurate and up-to-date. Ensure that the provider’s information is also correctly listed on the claim.

Check for Coding Errors

    • Review the procedure and diagnosis codes used on the claim. Verify that they are accurate, up-to-date, and supported by proper documentation. Ensure that modifiers are used appropriately when necessary.

Review Documentation

    • Examine the medical records and documentation associated with the claim. Ensure that the documentation supports the services billed and meets the payer’s requirements for medical necessity and coding guidelines.

Address Billing Errors

    • If the rejection is due to billing errors, such as incorrect coding or missing information, make the necessary corrections to the claim. This may involve revising the codes, adding modifiers, or providing additional documentation.

Appeal if Necessary

    • Consider appealing the decision if you believe the rejection was unjustified and the claim is valid. Follow the payer’s specific appeal process, typically involving submitting additional documentation and a formal request for reconsideration.

Correct and Resubmit the Claim

    • After addressing the rejection issues, correct the claim and resubmit it to the payer. Ensure that the resubmitted claim includes all required information and documentation.

Monitor Claim Status

    • Keep a close eye on the status of the resubmitted claim. Payers may take time to process and review resubmitted claims. Check the claim status regularly through the payer’s online portal or by contacting customer service.

Follow Up with the Payer

    • If the claim continues to be rejected or there are delays in processing, proactively contact the payer’s customer service to inquire about the status and seek clarification on any outstanding issues.

Prevent Future Rejections

    • To minimize future rejections, establish a robust billing process that includes regular training for your billing staff, staying updated on coding and billing guidelines, and conducting internal audits to proactively identify and address potential issues.

Use Electronic Health Records (EHR) and Practice Management Software

    • Implementing EHR and practice management software can help reduce billing errors, streamline the claims submission process, and improve accuracy and efficiency in OB/GYN billing.

Seek Expert Assistance

    • If you encounter persistent billing rejections or complex issues, consider consulting with a medical billing expert or a certified professional coder (CPC) specializing in OB/GYN coding and billing.
