CPT code 76825 – Fetal echocardiography, complete

Key takeaways

CPT Code 76825 covers a fetal echocardiogram with real-time 2D imaging, with or without M-mode recording. Doppler is reported separately with 76827 or 76828.

A complete fetal echo is usually billed as 76825 plus 76827 and add-on 93325, though some payers won’t pay 76827 alongside 76825.

Medical necessity needs a documented indication, such as family history of congenital heart disease, maternal diabetes, or a suspected cardiac anomaly on a prior scan.

Modifier 26 (professional component) and TC (technical component) apply when interpretation and equipment are billed by separate entities. Global billing needs neither.

Pabau’s claims management software helps maternal-fetal medicine (MFM) and OB/GYN practices flag missing modifiers and mismatched diagnosis codes before a 76825 claim goes out.

CPT Code 76825: Official descriptor and procedure overview

CPT Code 76825 covers echocardiography, fetal, cardiovascular system, real time with image documentation (2D), with or without M-mode recording.

The American Medical Association (AMA), which maintains the CPT code set, assigns it to a fetal cardiac study rather than a routine anatomy scan.

Real-time two-dimensional imaging of the fetal heart is what satisfies the 76825 descriptor. M-mode, which measures chamber dimensions and wall motion, is optional. Spectral Doppler of blood flow across the valves and great vessels is billed separately as 76827 or 76828. Color flow mapping is billed as add-on 93325.

The code sits in the Obstetrical subsection of Diagnostic Ultrasound (76801-76828), within the Radiology chapter of the CPT code set. Its partner, 76826, is the follow-up or repeat study of 76825. The study is typically performed between 18 and 24 weeks of gestation, though some indications prompt earlier or later imaging.

When is CPT Code 76825 used? Clinical indications and medical necessity

CPT Code 76825 is medically necessary when a clinical indication puts the fetus at elevated risk of congenital heart disease (CHD) or another cardiac anomaly. Routine low-risk pregnancy surveillance is explicitly excluded from coverage by most payers. Coders at OB/GYN practices should confirm the ordering diagnosis before submitting a 76825 claim.

Accepted clinical indications vary by payer Local Coverage Determination (LCD). Most major commercial insurers and CMS guidelines recognize the indications below. They follow the American Society of Echocardiography (ASE) and American Institute of Ultrasound in Medicine (AIUM) practice parameters:

• Family history of congenital heart disease in a first-degree relative (parent or sibling)
• Maternal pregestational or gestational diabetes with poor glycemic control
• Elevated nuchal translucency on first-trimester screening
• Suspected cardiac anomaly on prior obstetric ultrasound
• Maternal phenylketonuria (PKU) with elevated phenylalanine levels during pregnancy
• Fetal chromosomal abnormality associated with cardiac defects (e.g., trisomy 21, 18, or 13)
• Fetal hydrops or arrhythmia identified on surveillance scan
• Maternal lupus (SLE) with anti-Ro/SSA or anti-La/SSB antibodies (risk of fetal heart block)
• Maternal rubella or other teratogenic infection in first trimester
• In vitro fertilization (IVF) pregnancy in some payer policies

The ICD-10-CM diagnosis code attached to the claim must support the specific indication. Common supporting codes include:

• Z84.89 (family history of other specified conditions)
• O35.8XX (maternal care for other specified fetal abnormalities and damage)
• Z82.49 (family history of ischemic heart disease and other diseases of the circulatory system)
• O24.419 (gestational diabetes mellitus in pregnancy, unspecified control)

Payers check the diagnosis code against their LCD before adjudicating the claim. A generic diagnosis such as Z34.02 (encounter for supervision of normal first pregnancy) will trigger a medical necessity denial.

CPT Code 76825 vs 76826: Initial vs follow-up fetal echocardiography

CPT Code 76825 describes the initial fetal echocardiogram, and 76826 describes each follow-up or repeat study on the same fetus during the same pregnancy. The two codes form a defined pair. Billing 76825 for every session, after the initial study is done, is a coding error that payers deny.

Billing 76825 and 76826 on the same date of service for the same fetus needs modifier 59 (distinct procedural service) and a documented clinical basis. Even then, it invites scrutiny. The safer practice is to bill 76825 for the initial study and reserve 76826 for every later session.

Related codes: Fetal Doppler, 76816, 76830, and 93325

Several adjacent codes are frequently confused with CPT Code 76825. Selecting the wrong code is one of the leading causes of denials for fetal cardiac studies.

Doppler and color flow: Doppler is not part of 76825. According to the SMFM coding guidance, a full study with spectral Doppler and color flow is billed as 76825, 76827, and add-on 93325. Some payers still refuse 76827 on the same claim as 76825, so check the contract first. Billing 76816 and 76825 on the same date for the same fetus requires modifier 59 and a documented clinical rationale.

The map below shows which code each part of the study lands on, for the first scan and for every follow-up.

One caution on the Doppler line: it only pays if the report carries the Doppler findings, which the documentation section below covers.

Which modifiers apply to CPT Code 76825?

The modifier for CPT Code 76825 depends on who owns the equipment, who interprets the study, and the facility setting. A wrong or missing modifier leads to a payment reduction or a denial.

• Modifier 26 (professional component): Appended when the physician provides only the interpretation and written report. The facility or a separate entity owns and operates the ultrasound equipment. The physician bills 76825-26; the facility bills 76825-TC.
• Modifier TC (technical component): Appended by the facility or equipment owner when billing only for the technical component, including equipment, supplies, and non-physician labor. Cannot be used by the interpreting physician.
• No modifier (global billing): Used when the same provider owns the equipment and performs and interprets the study. Both components are captured in the global fee. Most private MFM or pediatric cardiology offices that bill under their own NPI bill globally.
• Modifier 59 (distinct procedural service): Used when 76825 is billed on the same date as 76816 or another bundled code. National Correct Coding Initiative (NCCI) edits would otherwise deny the second code. Documented clinical justification for both studies is required.
• Modifier 52 (reduced services): Used when fetal position, maternal habitus, or a technical limitation stops the physician from completing all required views. Reduces the allowable accordingly.

The CMS Physician Fee Schedule assigns 76825 a split-billing indicator, so the professional and technical components are separately billable. Verify the indicator each year, because CMS updates the fee schedule every January. The global period for 76825 is XXX, which means the global surgery concept does not apply to this diagnostic imaging code.

Documentation requirements: What must be in the fetal echo report

Incomplete documentation is the most common denial trigger for 76825 claims across commercial payers and Medicare. To hold up at audit, the fetal echocardiography report needs the following elements.

• Patient and fetal identifiers: Maternal name, date of birth, gestational age, and date of service.
• Clinical indication: The specific reason for the study, stated explicitly and linked to the ordering ICD-10-CM diagnosis code.
• Interpreting physician credentials: Name, specialty (MFM, pediatric cardiology, or other qualified specialty), and NPI. Some payer LCDs restrict coverage to studies interpreted by MFM or pediatric cardiologists.
• Views documented: Four-chamber view, left and right ventricular outflow tracts, ductal arch, aortic arch, superior and inferior vena cava, and pulmonary veins. Incomplete views must be explained by documented fetal position or technical limitation.
• M-mode measurements: Ventricular dimensions and wall motion, when technically feasible.
• Doppler findings (only when 76827, 76828, or 93325 is also billed): Spectral Doppler across the mitral, tricuspid, aortic, and pulmonary valves. Add a color Doppler map of the atrial and ventricular septa. State normal findings, and describe abnormal ones with measurements.
• Impression/conclusion: A clinical impression stating whether cardiac anatomy and function are normal or abnormal, with specific findings. Add a follow-up or referral recommendation if indicated.

Payer auditors look for a structured fetal echo report rather than a brief addendum to a routine obstetric ultrasound. Cardiac findings tucked into an anatomy scan report as a footnote will not support the claim.

Medicare and Medicaid reimbursement for 76825

Medicare pays 76825 under the Medicare Physician Fee Schedule (MPFS). The 2026 national payment for the global service is $261.86 before locality adjustment. Your rate varies with your geographic payment locality and the component you bill.

The figures above come from the FastRVU 2026 RVU lookup tool. Apply your locality’s geographic practice cost index (GPCI) for a precise estimate. The CMS lookup tool also lists the separate amounts for 76825-26 and 76825-TC, which this table does not reproduce.

Medicaid rates for fetal echocardiography vary widely by state. Most state Medicaid programs cover 76825 when medical necessity criteria are met, but prior authorization rules and payment rates differ. Some states apply their own coverage policies and may limit covered studies per pregnancy. Check the state agency’s current fee schedule before projecting revenue.

Prior authorization requirements by payer

Most major commercial payers and many managed Medicaid plans require prior authorization for CPT Code 76825. Medicare fee-for-service generally does not. A study performed without a required authorization is denied as non-covered, even when the clinical indication is clear. That denial cannot be appealed on medical necessity grounds alone.

Sound insurance eligibility verification before scheduling the study is the first line of defense. During the verification call or portal check, confirm whether the patient’s plan requires prior authorization for 76825. If it does, ask which clinical documents the payer needs to approve the request.

If your team is still mapping out its prior authorization process, start with the paperwork. A complete submission for fetal echocardiography typically includes:

• The ordering physician’s clinical note documenting the specific indication
• The referring obstetric ultrasound report that identified the concern (if applicable)
• Relevant laboratory results (e.g., nuchal translucency measurement, maternal diabetes labs)
• Family history documentation in the medical record
• The proposed CPT code (76825) and the supporting ICD-10-CM diagnosis code(s)
• The name and specialty of the performing/interpreting physician

Commercial payer turnaround for urgent obstetric authorizations is typically 24 to 72 hours. Standard requests may take 5 to 10 business days. When a payer denies a prior authorization, cite the ASE or AIUM clinical practice guidelines directly in the appeal.

Common denial reasons for CPT Code 76825 and how to appeal

Fetal echocardiography denials cluster around a predictable set of root causes, and the cause decides the appeal path. Payers report each one with a claim adjustment reason code, and our guide to denial codes explains how to fix them. Use a structured denial management workflow to sort and route each denial within 24 hours.

• Medical necessity not established: The diagnosis code on the claim does not match an accepted indication in the payer’s LCD. Appeal with a copy of the physician’s clinical note, the supporting diagnosis documentation, and a reference to the applicable ASE guideline section.
• No prior authorization on file: The service was performed without an approved authorization. If the clinical urgency was documented, appeal with a retrospective authorization request and supporting clinical records. Prevention is the only reliable solution.
• Incomplete documentation: The fetal echo report lacks required elements, such as a complete view list. Missing Doppler findings only count when 76827 or 76828 is also billed. Appeal with the complete, corrected report. If the original report was genuinely incomplete, submit a physician attestation explaining the technical limitation.
• NCCI bundling edit: 76825 and 76826 billed on the same date without modifier 59. Appeal by removing the incorrect secondary code or, if both were genuinely distinct services, by adding modifier 59 with a written clinical justification.
• Provider not credentialed for fetal echo: Some payer LCDs restrict coverage to studies performed by MFM specialists or pediatric cardiologists. Appeal with the performing physician’s credentials and board certifications. If the provider does not meet the payer’s specialty requirement, the denial usually cannot be appealed on medical grounds.
• Wrong diagnosis code: A general obstetric supervision code rather than a specific risk-factor code was submitted. Correct the claim with the appropriate ICD-10-CM code and resubmit.

Billing tips to keep 76825 claims clean

Most 76825 billing errors are preventable. A pre-submission checklist catches the majority of them before the claim leaves the practice.

• Confirm the diagnosis code before submission. The ICD-10-CM code must reflect the specific clinical indication, not a generic obstetric supervision code. Cross-reference the ordering note against the claim before submitting.
• Verify the interpreting physician’s credentialing status with each payer. MFM and pediatric cardiology credentialing for fetal echo is payer-specific. A physician credentialed for general OB ultrasound may not be recognized for 76825 by the same payer.
• Attach the fetal echo report to the claim or have it ready. Most payers request the report on any 76825 claim audit. Having it attached, or retrievable within 24 hours, shortens the appeal cycle.
• Apply the correct modifier for the billing setting. Modifier 26 for interpretation-only; TC for facility equipment billing; no modifier for global. Mismatched modifiers cause payment discrepancies that require corrected claim submissions.
• Check NCCI edits before submitting 76825 with 76826 or 76816. CMS updates the edit pairs every quarter, so recheck them in a tool such as AAPC Codify each quarter.
• Submit a clean claim the first time. A claim that clears every edit on the first pass gets paid without rework. A denial means staff time spent correcting and resubmitting before any payment arrives.

Run the checklist on every claim, not only the ones that look complicated. Our guide to the clean claim standard walks your billing team through what payers check on first pass.

How claims management software reduces denials for CPT Code 76825

Today, most MFM and OB/GYN billing teams catch a missing modifier or a mismatched diagnosis code only after the denial arrives. Pabau, the practice management platform we build, moves that check to before submission.

In Pabau’s claims management software, claim rules flag missing modifiers, mismatched diagnosis codes, and NCCI edit conflicts before a 76825 claim goes out. The built-in CPT and ICD-10 catalogs show coders the relevant code combinations at the point of entry.

Claims then go out through Pabau’s Claim.MD clearinghouse integration, which also runs real-time eligibility checks before the visit. When the payer pays, the 835 electronic remittance advice comes back into Pabau and matches the payment to the claim. Your team reconciles fetal echo revenue without logging in to a payer portal.

Simplify fetal echo billing with Pabau

Pabau flags missing modifiers and mismatched diagnosis codes before submission, then sends 76825 claims through the Claim.MD clearinghouse. Payments match back to each claim automatically.

Conclusion

Treat 76825 as one line of a fetal echo claim, not the whole claim. Code the 2D study, then add 76827 and 93325 when the report documents Doppler and color flow, after checking that the payer allows them together.

The payoff is that the study you already performed gets paid in full, the first time. The trade-off is discipline up front: the indication, the authorization, and the report all have to be in place before the claim goes out.

Pabau helps flag missing modifiers and mismatched diagnosis codes before submission, so fewer fetal echo claims come back denied. Book a demo to see how Pabau handles fetal echo billing for MFM and OB/GYN practices.
