The Complete Hysteroscopy Coding Guide: CPT Codes 58558 Through 58565

Hysteroscopy occupies a unique position in gynecological care.Hysteroscopy procedures offer both diagnostic and surgical solutions for a range of gynecological conditions, and each one comes with its own coding nuances.

For billing accuracy, coders must carefully review the operative report to confirm what was actually performed, whether tissue was removed, whether D&C was included, whether polyps or fibroids were treated, and whether the documentation supports the selected CPT code. 

The nuances of coding directly impact code selection, reimbursement optimization, and compliance. Even small documentation differences can lead to coding errors, denials, or underpayment.

When to Report CPT 58558 for Retained Products of Conception (RPOC)?

CPT® 58558 is used when a provider performs a surgical hysteroscopy that includes endometrial sampling or polyp removal, with or without dilation and curettage (D&C). This applies when the procedure involves:

• Endometrial biopsy
• Polypectomy
• Dilation and curettage performed under hysteroscopic guidance. Importantly with findings documented in the operative report

The operative report must clearly reflect hysteroscopic intervention. For this code, vague or incomplete documentation will not hold up against payer expectations. A real compliance risk. Common phrases that support accurate coding include:

• “Hysteroscopic polypectomy”
• “Endometrial biopsy under hysteroscopy”
• “Hysteroscopic D&C”
• “Endometrial sampling”
• “Visualization with removal of polyps”

Why Coding 58558 Can Get Tricky?

Although hysteroscopy may be used to remove retained products of conception (RPOC), that alone does not automatically justify reporting 58558. The key factor is the clinical context, not just the technique.

If the patient is still experiencing an incomplete abortion, then 58558 should not be reported, even if a hysteroscope is used during the procedure. In such cases, the correct code is 59812 (treatment of incomplete abortion, surgically completed).

Diagnosis selection carries equal weight in this process. The documentation should reflect an incomplete abortion diagnosis, such as O03.4, rather than a missed abortion. In this case, coding the wrong diagnosis can lead to claim denials or compliance issues. A distinction that payers will not overlook.

Modifier Consideration

Modifier 22 can be added to 59812 only when the procedure exceeds the standard expected level of work under CPT Code 59812. In this code, the hysteroscopic approach must be reflected directly in the operative report. For this code, the operative report needs to back that up with specifics, such as prolonged procedure time, noted technical difficulty, or increased patient risk. General language will not satisfy payer expectations, but with clear and detailed entries in the operative report, the modifier holds up.

Look for documentation terms like:

• “Incomplete abortion”
• “Retained products”
• “Hysteroscopic removal”
• “Persistent or continued bleeding”

When 58558 Is Appropriate for RPOC?

There are limited scenarios where 58558 can be correctly reported for RPOC. This usually occurs when the procedure is performed well after the initial pregnancy event (typically beyond 90 days) and is considered treatment of a sequela, rather than part of an active obstetrical condition.

In such cases:

• Use O94 (sequelae of pregnancy-related complications)
• Pair with a symptom-based diagnosis (e.g., abnormal uterine bleeding such as N93.8)
• In some situations, 58120 (nonobstetrical D&C) may also be appropriate depending on the procedure performed

Key Takeaways

Accurate coding depends on three major elements, such as:

• Timing where the case still obstetrical or now a sequela?
• Clinical status means Incomplete abortion vs nonobstetric condition
• Provider documentation required Clear indication of biopsy, polypectomy, or sampling

An ongoing incomplete abortion case gets reported under 59812. The moment a pregnancy-related indication is present, 58558 is off the table.

58558 only enters the picture when the procedure falls entirely outside the obstetrical context. Not partially outside. Entirely. For this code, the documentation must actively support that separation, but with language specific enough to remove any doubt about the clinical indication driving the intervention.

CPT 58559 for Hysteroscopic Lysis of Adhesions

CPT® 58559 is reported when a provider performs hysteroscopic lysis of intrauterine adhesions, regardless of the method used. This procedure is most often associated with conditions such as Asherman’s syndrome or uterine synechiae, which are commonly linked to infertility.

Accurate coding here depends heavily on identifying the true clinical indication and ensuring that the diagnosis reflects the reason for the procedure rather than unrelated or incidental findings.

Understanding the Clinical Context

One of the most common challenges with 58559 starts in the pathology report. Prior pregnancy-related findings show up. And coders react to them instead of the documented indication. That reaction is where the coding error begins.

A patient may undergo hysteroscopy with adhesiolysis and D&C, and pathology may reveal residual placental tissue from a delivery that occurred years earlier. This does not make it a postpartum case. The procedure was not performed to manage a pregnancy complication, but with a completely separate clinical indication driving it. That distinction matters more than most coders recognize.

If the operative report reflects infertility or intrauterine adhesions as the indication, the diagnosis should align with those conditions. Payer expectations follow the documented intent. Although it was not the incidental finding sitting in a pathology report from a prior pregnancy.

Appropriate diagnosis codes in this context include:

• N85.6 (Intrauterine synechiae)
• N97.2 (Female infertility of uterine origin)

Postpartum-related codes should be avoided unless the procedure was actually intended to treat a recent obstetrical complication.

Documentation Cues to Support 58559

Reviewing the operative note confirms whether the code selection holds up. For this code, look for terminology that clearly points to a nonobstetric purpose. These are the phrases that hold up against payer expectations:

• Uterine synechiae
• Asherman’s syndrome
• Lysis of adhesions
• Intrauterine scarring
• Infertility evaluation

These terms indicate a nonobstetric purpose and support proper code selection.

Coding with Multiple Procedures

Adhesiolysis performed alongside additional procedures such as D&C or endometrial sampling allows both services to be reported. Only when documentation actively supports each one.

A scenario in this case may be taken into account:

If there is a patient with a history of complicated placental removal presents with secondary infertility. Hysteroscopy reveals dense intrauterine adhesions, which are surgically lysed. Curettage is also performed, and pathology identifies trophoblastic remnants. Two separate, documentable services, but with the operative report carrying the weight of justifying both. Coders who miss that distinction leave the claim exposed.

In this situation:

• Report 58559 for adhesiolysis
• Report 58558-51 for D&C and sampling
• Assign diagnoses based on infertility and intrauterine adhesions, not the incidental pathology finding

Important Coding Considerations

The diagnosis must align with the intent of the surgery, not with what is incidentally discovered during the procedure. Misalignment between procedure and diagnosis is a frequent cause of claim denials.

CPT® 58560 for Hysteroscopic Resection of Uterine Septum

CPT® 58560 is reported when a provider performs a hysteroscopic procedure to divide or resect an intrauterine septum. This type of intervention addresses specific uterine conditions. It is typically performed in cases of recurrent pregnancy loss, infertility, or congenital uterine abnormalities. Not all cases present the same way.

What makes this code distinct is that septum resection is not the same as general adhesiolysis. It is a separate, clearly defined surgical objective, and should be coded independently when properly documented.

When to Report 58560 with Other Procedures?

There are situations where septum resection is performed alongside other hysteroscopic procedures, particularly lysis of adhesions. When both are clearly documented:

• 58560 can be reported for septum resection
• 58559 can be reported for adhesiolysis

These procedures are not restricted by bundling edits, which means they can be billed together without modifiers, as long as each service is supported in the operative report.

Laparoscopy Considerations

In some cases, the surgeon uses laparoscopy during hysteroscopic septum resection to monitor uterine integrity and reduce the risk of complications such as perforation. This is a supportive role, not a separately billable one. When laparoscopy is used solely for guidance, it is generally not reimbursable on its own.

A separate diagnostic laparoscopy may only be reported when documented medical necessity exists. The neccessities include evaluation of pelvic pain or suspected uterine injury. Without that specific indication clearly noted in the operative report, it should not be coded independently. Payers will not accept vague reasoning here.

Documentation Clues to Support 58560

For this code, these are the phrases that support accurate coding:

• Uterine septum
• Septum resection
• Division of septum
• Congenital uterine anomaly
• Hysteroscopic metroplasty
• Laparoscopic guidance for uterine safety

These terms confirm that the procedure focused on correcting a structural uterine defect.

Practical Coding Scenario

Consider a patient with a history of recurrent miscarriages who undergoes hysteroscopy. During the procedure, the provider identifies both intrauterine adhesions and a uterine septum. Adhesions are lysed, and the septum is surgically resected. A laparoscope is used only to ensure uterine safety, with no additional findings.

In this case:

• Report 58559 for adhesiolysis
• Report 58560 for septum resection
• Do not report laparoscopy separately, as it was used only for guidance

Key Takeaway

CPT® 58560 should be selected when the primary surgical objective is correction of a uterine septum. If additional hysteroscopic procedures are performed, each may be coded separately when supported by documentation. Any use of laparoscopy should be evaluated carefully and reported only when it meets clear medical necessity criteria.

Coding Fibroid Removal, IUD Management, and Endometrial Ablation

After understanding how to code procedures related to retained products of conception, intrauterine adhesions, and septum resections, the next step is to focus on another set of commonly performed hysteroscopic interventions.

Procedures which intend to perform are:

• Hysteroscopic fibroid removal
• Impacted intrauterine device (IUD) removal
• Endometrial ablation
• IUD removal and reinsertion scenarios

These cases often introduce a different layer of complexity, particularly when multiple procedures are performed during the same session or when documentation does not clearly distinguish between routine and surgical interventions.

CPT® 58561 for Hysteroscopic Fibroid Removal

CPT® 58561 is used when a provider performs a hysteroscopic surgical procedure to remove leiomyomata. It is commonly known as submucosal fibroids. This is a targeted surgical intervention and should not be confused with procedures like endometrial biopsy or polypectomy, even though they may occur in the same anatomical area.

This procedure is typically performed to address symptoms. It includes abnormal uterine bleeding, infertility, or pelvic discomfort caused by fibroids located within the uterine cavity.

Key Documentation Indicators

Clear terminology in operative notes is the key to accurate reporting of 58561. These terms are:

• Submucosal fibroid
• Leiomyoma
• Hysteroscopic myomectomy
• Fibroid resection
• Type 0 or Type 1 fibroid (based on FIGO classification)

These details help distinguish fibroid removal from other intrauterine procedures.

Coding with Multiple Procedures

Hysteroscopic fibroid removal is often performed alongside other procedures, which makes correct modifier usage essential.

For example, a provider may perform:

• Fibroid removal
• Endometrial ablation
• Dilation and curettage (D&C)

In this scenario:

• Report 58561 for fibroid removal
• Report 58563-51 for endometrial ablation

These two codes are not bundled under current coding guidelines, so they can be reported together using modifier 51 to indicate multiple procedures.

It is important not to use modifier 59 in this case, as there is no bundling edit that needs to be overridden. Misuse of modifiers can lead to unnecessary claim scrutiny or denials.

Also keep in mind that procedures like D&C may be included depending on the primary service performed, so documentation should always be reviewed carefully before assigning additional codes.

CPT® 58562 for Hysteroscopic Removal of an Impacted IUD

CPT® 58562 is reported when a provider performs a hysteroscopic surgical removal of an impacted foreign body, most commonly an intrauterine device (IUD) that is embedded within the uterine wall. This code applies only when the removal requires a true surgical approach due to the IUD being lodged in the endometrium or myometrium.

The key distinction here is that the device must be impacted. If the IUD is simply retained, difficult to locate, or has missing strings, this code would not be appropriate.

Documentation Requirements

To confirm complexity and embedding in 58562, the operative report should include terminology such as:

• Impacted IUD
• Embedded in endometrium or myometrium
• Hysteroscopic removal of foreign body
• Surgical dissection required
• Difficult extraction under hysteroscopic visualization

Without these details, reporting 58562 may lead to denials.

Coding IUD Removal with Reinsertion

In cases where the provider removes an impacted IUD hysteroscopically and inserts a new one during the same session:

• Report 58562 for the removal
• Report 58300 for the insertion of the new IUD

It is essential that documentation explicitly states the IUD was embedded. The use of hysteroscopy alone does not establish medical necessity for this code.

When the IUD Is Not Impacted?

If the IUD is not embedded but requires hysteroscopy only for visualization or guidance, a different coding approach should be used:

• 58555 for diagnostic hysteroscopy
• 58301-51 for IUD removal
• 58300-51 which is for IUD insertion

Some payers perform both together but may not reimburse removal and insertion. In that case, modifier 22 or 59 works. But importantly it is depending on payer-specific policies and whether the documentation supports increased complexity.

CPT® 58563 for Hysteroscopic Endometrial Ablation

CPT® 58563 is reported for hysteroscopic surgical procedures performed to ablate or resect the endometrium, most commonly in patients with abnormal uterine bleeding that has not responded to conservative treatment. The goal of this procedure is the controlled destruction or removal of the endometrial lining to reduce or eliminate uterine bleeding.

Documentation Indicators

Reporting 58563 accurately starts with the operative report. There must be clearly mentioned endometrial ablation through specific terminology such as:

• Endometrial resection
• Ablation of endometrium
• Electrosurgical ablation
• Thermoablation
• Hysteroscopic control of uterine bleeding

These terms confirm that the procedure is therapeutic and focused on endometrial destruction.

Reporting with Other Hysteroscopic Procedures

Endometrial ablation is often performed alongside other hysteroscopic interventions. In such cases, correct coding depends on NCCI bundling rules and proper modifier use.

For example, if a provider performs both:

• Endometrial ablation
• Submucosal fibroid removal

Then:

• Report 58563 for ablation
• Report 58561-51 for fibroid removal

These services are not bundled under current NCCI guidelines, allowing both codes to be reported when clearly documented.

However, procedures such as D&C or polypectomy are generally considered included within the ablation service and should not be separately reported unless documentation strongly supports a distinct, separately identifiable procedure.

Example Scenario

A patient presents with chronic menorrhagia and undergoes hysteroscopic endometrial ablation. During the same operative session, a submucosal fibroid is also identified and removed.

In this case:

• Report 58563 for endometrial ablation
• Report 58561-51 for fibroid removal

Always verify payer-specific guidelines, particularly regarding multiple procedure reimbursement and anesthesia billing rules.

CPT® 58565 for Hysteroscopic Sterilization with Tubal Implants

CPT® 58565 is used when a provider performs hysteroscopic sterilization by placing permanent implants into both fallopian tubes to achieve tubal occlusion. This procedure is associated with systems such as Essure, where the intent is permanent female sterilization.

Documentation Requirements

To support 58565, the operative report should include clear language such as:

• Essure placement
• Hysteroscopic tubal occlusion
• Bilateral fallopian tube cannulation
• Placement of permanent sterilization implants
• Hysteroscopic sterilization

The defining requirement is bilateral placement, meaning both fallopian tubes must be successfully cannulated and implanted.

When Only One Tube Is Treated?

If implants are placed in only one fallopian tube due to anatomical or clinical limitations (such as prior occlusion of the opposite tube), the code remains 58565, but should be reported with modifier 52 to indicate reduced services. Documentation must clearly explain why the procedure was unilateral.

Example Scenario

A patient undergoes Essure sterilization. The provider successfully places implants in both fallopian tubes. In this case, report 58565 without a modifier.

If only the left tube is successfully treated due to prior occlusion of the right tube, report 58565-52, supported by operative documentation explaining the limitation.

Key Coding Considerations

This code should only be used when the intent is permanent sterilization. It is not appropriate for:

• Diagnostic hysteroscopy
• Tubal evaluation without implant placement
• Incomplete or exploratory procedures
