Billing and Coding Guide for OB-GYN Practices
Hysteroplasty for repair of uterine anomaly (Strassman-type) is reported with CPT 58540. This is a reconstructive gynecologic surgery done to improve some congenital uterine abnormalities, without removing the uterus.
The medical record must contain the correct information for the uterine anomaly, the surgery done to reconstruct the uterus, and the surgical technique. It's important to know when CPT 58540 applies and when other uterine codes apply in order to make clean claims and get proper reimbursement, as this code may be confused with other uterine codes.
CPT 58542: Laparoscopy, surgical, supracervical hysterectomy, for uterus 250 g or less; with removal of tube(s) and/or ovary(s).
This code is for a laparoscopic supracervical (or subtotal) hysterectomy, in which the surgeon removes the uterus corpus (body) and leaves the cervix intact.
CPT 58542 is the same type of hysterectomy as CPT 58541, but with the addition of removal of one or both fallopian tubes and/or one or both ovaries.
For CPT 58542 to apply, the uterus should be under 250 grams. It is carried out laparoscopically and the specimen removed via the abdominal route, possibly morcellated where appropriate.
Report code CPT 58542 for the entire service documented in the code.
The procedure should involve:
The uterine weight should be supported by appropriate documentation, such as the pathology report or operative documentation. When the uterus is evaluated for weight in the OR, the care team should not presume that it is below the 250-gram mark just because the pre-op estimation is below that weight.
One of the primary differences between CPT 58541 and 58542 is the removal of the tubes and/or ovaries. If the removal of the adnexal structures has been documented as part of the procedure, then the code selection should reflect what service was performed.
Since CPT 58542 is part of a four code family that has only a weight difference and adnexal removal, it is crucial to review the documentation carefully before using this code. When the following conditions are not met, do not report 58542:
Medical record supports only modifiers when the specific circumstances are in compliance with the modifier requirements.
Consider using Modifier 22 if the procedure requires significantly more work than is typical.
The operative report should describe the condition or conditions that caused the extra procedural services. A general statement like the procedure was difficult doesn't seem to be enough.
Modifier 51 may be used for multiple procedures performed during the same operative session where applicable, and subject to applicable rules of the payers.
It should not be relied upon to circumvent NCCI edits, or to report separately services that are already covered by the primary procedure.
Modifier 59 is used to indicate a separate and distinct service when a service is truly separate and distinct.
Does not belong to be added at the end just to be an NCCI edit. There should be a clear record of the circumstances which support separate reporting.
If an unplanned, related surgical procedure must be performed in the operating or procedure room during the postoperative period, then modifier 78 will be used when the requirements for modifier 78 are met.
When the surgical procedure is performed during the global period and it is a completely different procedure that is actually unrelated to the original hysterectomy, modifier 79 may be used if appropriate.
There are a number of factors that must be met for CPT 58542 to be used and accurate documentation is crucial.
The medical record should assist with:
In the operating report the surgeon should specify which adnexal structures were removed. Documentation should not be relied upon to indicate whether the procedure was a tube, ovary or both.
Uterine weight should also be checked against existing pathology or operative records as this will determine the procedure for categorization in either the 250-gram or greater than-250-gram category.
Reimbursement for CPT 58542 varies according to the payer, geographic location, contracted reimbursement rate, applicable fee schedule, and individual claim circumstances.
Before submitting the claim, the billing team should verify:
Some examples of coding distinctions between CPT 58542 and adjacent codes are illustrated below:
Scenario 1: A patient has a fully laparoscopic supracervical hysterectomy and bilateral salpingectomy at the same time. The uterus is confirmed as having a weight of 180g. CPT 58542 is reported.
Scenario 2: The same laparoscopic supracervical hysterectomy is done, but the tubes and ovaries are not removed. There is no distinction between the CPT codes 58541 and 58542 because the adnexal component is not present.
Scenario 3: A laparoscopic supracervical hysterectomy with bilateral oophorectomy has been performed and the uterus is seen on pathology to be 310 grams. This weight exceeds the 250 gram limit so the code should be CPT 58544 and not 58542.
Scenario 4: The patient returns to the operating room, two weeks after a laparoscopic supracervical hysterectomy with unilateral salpingo-oophorectomy, with a complication from the initial surgery. Moderator 78 is used to report the second procedure, as this was a return that was not planned during the period of the global procedure.
CPT 58542 is simple to under code or over code as it has three different codes in the same family, one step away. When a payer is looking at a hysterectomy note, for example, that doesn't explicitly include removal of the adnexa or a pathology report that contradicts the weight threshold billed for the procedure, it's likely enough to cause a payer inquiry or even a complete denial, even if the care itself was completely warranted.
CureCloudMD's OBGYN medical billing is designed to detect exactly this type of discrepancy: Coders who know how to read the operative notes and verify that they have everything needed for the claim and that the documentation includes the adnexal and weight modifiers; the right modifier logic based on the payer's NCCI policy as opposed to default overrides.
That skill is the one that helps practices with CureCloudMD consistently achieve a high clean claim rate and keep claim denials at less than 1%, even for hysterectomy claims, where it's not necessarily a clinical opinion, but generally coding accuracy.
