Cpt Code For Hysteroscopy With Dilation And Curettage

Hysteroscopy with dilation and curettage (D&C) is a common gynecological procedure used for both diagnostic and therapeutic purposes. Accurately coding this procedure is crucial for proper billing and reimbursement. This comprehensive guide will delve into the CPT codes associated with hysteroscopy with D&C, providing detailed explanations, coding scenarios, and essential considerations to ensure accurate coding practices.

Understanding Hysteroscopy with Dilation and Curettage (D&C)

Hysteroscopy is a minimally invasive procedure that allows a physician to visualize the inside of the uterus using a thin, lighted tube called a hysteroscope. Dilation and curettage (D&C) involves dilating the cervix and then using a curette (a surgical instrument) to scrape or suction the uterine lining. The combination of these two procedures allows for a thorough examination and treatment of various uterine conditions.

CPT Codes for Hysteroscopy with D&C

The primary CPT codes for hysteroscopy with D&C are:

• 58558 - Hysteroscopy, surgical, with sampling (biopsy) of endometrium and/or polypectomy, with or without D&C

This code is used when a hysteroscopy is performed with a biopsy of the endometrium (uterine lining) or a polypectomy (removal of a polyp), and may include a D&C.

• 58120 - Dilation and curettage, diagnostic and/or therapeutic (nonobstetrical)

This code is used for a D&C when it's performed without a hysteroscopy. It's important to note that if a hysteroscopy is performed with a D&C and another procedure like a biopsy or polypectomy, code 58558 takes precedence.

Detailed Breakdown of CPT Code 58558

CPT Code 58558: Hysteroscopy, surgical, with sampling (biopsy) of endometrium and/or polypectomy, with or without D&C

This code encompasses several components:

• Hysteroscopy: The visual examination of the uterine cavity using a hysteroscope.
• Sampling (Biopsy) of Endometrium: The removal of a small tissue sample from the uterine lining for microscopic examination.
• Polypectomy: The removal of one or more polyps from the uterine cavity.
• D&C (Dilation and Curettage): The dilation of the cervix followed by scraping or suctioning of the uterine lining.

When to Use CPT Code 58558:

This code is appropriate in the following scenarios:

• Hysteroscopy with Endometrial Biopsy: The physician performs a hysteroscopy and takes a biopsy of the endometrium to investigate abnormal bleeding or other uterine conditions. A D&C may or may not be performed.
• Hysteroscopy with Polypectomy: The physician performs a hysteroscopy and removes one or more polyps from the uterus. A D&C may or may not be performed.
• Hysteroscopy with Endometrial Biopsy and Polypectomy: The physician performs a hysteroscopy, takes a biopsy of the endometrium, and removes one or more polyps. A D&C may or may not be performed.
• Hysteroscopy with D&C and either Endometrial Biopsy or Polypectomy (or both): This is the most comprehensive scenario covered by this code.

Key Considerations for CPT Code 58558:

• "With or Without D&C": The inclusion of "with or without D&C" in the code description means that you should still use 58558 even if a D&C is not performed during the same session as the hysteroscopy and biopsy/polypectomy. The key is that the hysteroscopy, biopsy/polypectomy, and D&C (if performed) are all part of the same surgical session and are performed to address the same underlying condition.
• Documentation is Crucial: The operative report must clearly document all the procedures performed, including the hysteroscopy, biopsy/polypectomy (if applicable), and D&C (if applicable). This documentation supports the use of CPT code 58558.

Detailed Breakdown of CPT Code 58120

CPT Code 58120: Dilation and Curettage, diagnostic and/or therapeutic (nonobstetrical)

This code describes a dilation and curettage procedure performed without a hysteroscopy.

When to Use CPT Code 58120:

This code is appropriate when:

• D&C is Performed Alone: The physician dilates the cervix and scrapes or suctions the uterine lining without using a hysteroscope for visualization.

Key Considerations for CPT Code 58120:

• No Hysteroscopy: This code is only used when a hysteroscopy is not performed. If a hysteroscopy is performed, even if it's only for visualization and a D&C is subsequently performed, you should not use 58120. The bundled nature of 58558 usually encompasses these procedures.
• Non-Obstetrical: The code description specifies "nonobstetrical," meaning it is used for D&Cs performed for reasons other than pregnancy termination or management of pregnancy-related complications. For obstetrical D&Cs, different CPT codes apply.

Coding Scenarios: Hysteroscopy with D&C

Here are several coding scenarios to illustrate the correct application of CPT codes 58558 and 58120:

Scenario 1:

A patient presents with abnormal uterine bleeding. The physician performs a hysteroscopy and visualizes a polyp. The polyp is removed (polypectomy), and an endometrial biopsy is also taken. A D&C is performed to further address the bleeding.

• Correct Code: 58558 (Hysteroscopy, surgical, with sampling (biopsy) of endometrium and/or polypectomy, with or without D&C)
• Rationale: The hysteroscopy, polypectomy, endometrial biopsy, and D&C were all performed during the same surgical session.

Scenario 2:

A patient presents with postmenopausal bleeding. The physician performs a hysteroscopy and takes an endometrial biopsy. No polyps are found, and a D&C is performed.

• Correct Code: 58558 (Hysteroscopy, surgical, with sampling (biopsy) of endometrium and/or polypectomy, with or without D&C)
• Rationale: The hysteroscopy, endometrial biopsy, and D&C were all performed during the same surgical session. The code includes "with or without D&C."

Scenario 3:

A patient presents with heavy menstrual bleeding. The physician performs a D&C without a hysteroscopy to reduce the bleeding.

• Correct Code: 58120 (Dilation and curettage, diagnostic and/or therapeutic (nonobstetrical))
• Rationale: A hysteroscopy was not performed.

Scenario 4:

A patient has a hysteroscopy performed, and a small fibroid is noted. The fibroid is too large to remove hysteroscopically. A D&C is performed.

• Correct Code: 58558 (Hysteroscopy, surgical, with sampling (biopsy) of endometrium and/or polypectomy, with or without D&C)
• Rationale: While the fibroid removal wasn't completed hysteroscopically, the hysteroscopy was performed. The D&C during the same operative session falls under 58558. If the fibroid were removed via a separate procedure (e.g., laparotomy), that would be coded separately.

Scenario 5:

A physician performs a hysteroscopy for visualization. Finding no polyps or other abnormalities, they proceed with a D&C due to the patient's reported heavy bleeding. No biopsy is performed.

• Correct Code: 58558 (Hysteroscopy, surgical, with sampling (biopsy) of endometrium and/or polypectomy, with or without D&C)
• Rationale: Even though no biopsy or polypectomy was performed, the hysteroscopy was done before the D&C in the same operative session. This makes 58558 the appropriate code. Documentation should support the medical necessity of both procedures.

CPT Coding Guidelines and Bundling Issues

Understanding CPT coding guidelines and bundling issues is critical for accurate coding of hysteroscopy with D&C.

• Bundling: CPT codes are often bundled, meaning that certain procedures are considered part of a larger, more comprehensive procedure. In the case of hysteroscopy with D&C, the hysteroscopy and D&C are often bundled together, particularly when performed during the same surgical session. This is why 58558 often takes precedence.
• Modifier Usage: Modifiers are used to provide additional information about a procedure or service. In some cases, a modifier may be necessary to unbundle a bundled code or to indicate that a procedure was performed separately. However, in the context of hysteroscopy with D&C, modifiers are rarely needed when using 58558 appropriately. If the hysteroscopy and D&C are performed on different days, then modifiers would likely be needed to indicate separate sessions.
• NCCI Edits: The National Correct Coding Initiative (NCCI) edits are a set of rules developed by the Centers for Medicare & Medicaid Services (CMS) to prevent improper coding and billing. These edits identify pairs of codes that should not be billed together because one code is considered to be included in the other. Coders should be aware of NCCI edits related to hysteroscopy and D&C to ensure accurate coding.

ICD-10 Diagnosis Codes

In addition to CPT codes, it is essential to assign appropriate ICD-10 diagnosis codes to reflect the reason for the hysteroscopy with D&C. Common ICD-10 codes associated with this procedure include:

• N93.9: Abnormal uterine and vaginal bleeding, unspecified
• N84.0: Endometrial polyp
• N85.8: Other specified noninflammatory disorders of uterus
• R10.2: Pelvic and perineal pain
• D25.9: Leiomyoma of uterus, unspecified

The selection of the appropriate ICD-10 code(s) should be based on the patient's specific diagnosis and the findings during the hysteroscopy and D&C. Accurate and specific ICD-10 coding is essential for proper reimbursement and for tracking the prevalence of various gynecological conditions.

Documentation Requirements

Comprehensive and accurate documentation is essential for supporting the CPT and ICD-10 codes reported for hysteroscopy with D&C. The operative report should include the following information:

• Patient Demographics: Name, date of birth, medical record number
• Date of Procedure: The specific date on which the hysteroscopy and D&C were performed
• Preoperative Diagnosis: The patient's condition or symptoms that led to the decision to perform the procedure
• Postoperative Diagnosis: The findings during the hysteroscopy and D&C, including any polyps, abnormalities, or other relevant information
• Procedure Details: A detailed description of the steps taken during the hysteroscopy and D&C, including the instruments used, the size and location of any polyps removed, and the method of endometrial sampling (if applicable)
• Complications: Any complications that occurred during the procedure, and how they were managed
• Anesthesia: The type of anesthesia used
• Physician Signature: The signature of the physician who performed the procedure

Clear and detailed documentation ensures that the coding accurately reflects the services provided and supports the medical necessity of the procedure.

Common Mistakes to Avoid

Several common mistakes can lead to inaccurate coding of hysteroscopy with D&C. Here are some pitfalls to avoid:

• Using 58120 When a Hysteroscopy Was Performed: This is a frequent error. Remember, if a hysteroscopy is performed, even if it's just for visualization, code 58558 is generally the correct choice if a biopsy or polypectomy (or D&C) occurs during the same operative session.
• Failure to Document All Procedures Performed: The operative report must clearly document all the procedures performed, including the hysteroscopy, biopsy/polypectomy (if applicable), and D&C (if applicable). Incomplete documentation can lead to undercoding or inaccurate coding.
• Ignoring Bundling Issues: Be aware of CPT coding guidelines and NCCI edits related to hysteroscopy and D&C. Understand which procedures are bundled together and when it may be appropriate to use a modifier.
• Using Incorrect ICD-10 Codes: Ensure that the ICD-10 diagnosis codes accurately reflect the patient's condition and the reason for the hysteroscopy with D&C. Avoid using unspecified codes when more specific codes are available.
• Lack of Medical Necessity: Ensure that the documentation supports the medical necessity of both the hysteroscopy and the D&C. Payers may deny claims if the procedures are not medically necessary or if the documentation does not support the medical necessity.

Conclusion

Accurate coding of hysteroscopy with dilation and curettage (D&C) is essential for proper billing and reimbursement. By understanding the nuances of CPT codes 58558 and 58120, following CPT coding guidelines, and ensuring comprehensive documentation, coders can avoid common mistakes and ensure that claims are processed correctly. Staying up-to-date on coding changes and payer policies is also crucial for maintaining accurate coding practices in the ever-evolving field of medical coding. By mastering these coding principles, healthcare providers can optimize their revenue cycle and provide high-quality care to their patients.
