CPT code 49585 – Umbilical hernia repair (deleted 2023)

Key takeaways

CPT code 49585 (open repair of a reducible umbilical hernia, age 5 or older) was deleted on January 1, 2023. Use it only for earlier dates of service.

Umbilical hernia repairs from 2023 onward use 49591-49596 for an initial repair or 49613-49618 for a recurrent one.

The new codes are chosen by total defect size and by whether the hernia is reducible or incarcerated/strangulated, not by age or approach.

The 2023 codes include mesh when placed and carry a 0-day global period, where 49585 carried a 90-day one.

Record the total defect size in centimeters in the operative note, or the claim falls back to the smallest size band.

CPT code 49585: What it described and why it was deleted

CPT code 49585 was the code for repair of a reducible umbilical hernia in a patient aged 5 years or older.

The American Medical Association (AMA) deleted it from the CPT code set effective January 1, 2023.

So the code now has two answers, depending on the date of service. For a repair on or before December 31, 2022, 49585 is still the code that claim carries. For any later repair, payers reject 49585 as a deleted code, and the procedure is billed with the new anterior abdominal hernia codes.

The old codes split hernia repair by hernia type, patient age and approach. The 2023 codes drop all three. They group epigastric, incisional, ventral, umbilical and spigelian hernias together as anterior abdominal hernias, repaired by any approach. Each repair is then graded by total defect size and by whether the hernia is reducible or incarcerated/strangulated.

The same change deleted 18 hernia repair codes in all. That includes the open codes 49560, 49561, 49565, 49566, 49568, 49570, 49572, 49580, 49582, 49585, 49587 and 49590, plus the laparoscopic codes 49652-49657. Inguinal and femoral hernia repair codes were not part of this change.

What 49585 covered before 2023

For a pre-2023 claim, 49585 applied when three conditions were met. The hernia was umbilical or paraumbilical, the patient was at least 5 years old, and the hernia was reducible. An incarcerated or strangulated umbilical hernia in the same age group used 49587, and a laparoscopic repair used 49652 or 49653.

49585 carried a 90-day global surgical period. The surgical fee bundled the repair itself with routine follow-up visits, wound checks and suture removal for 90 days after surgery.

What to bill instead of 49585: The 2023 hernia repair codes

From January 1, 2023, an umbilical hernia repair is reported with one code from two parallel ranges. Use 49591-49596 for an initial repair and 49613-49618 for a recurrent repair at a previously repaired site. Each code covers open, laparoscopic and robotic approaches, and includes mesh when it is placed.

Two more codes complete the family. 49621 and 49622 cover parastomal hernia repair, initial or recurrent, reducible or incarcerated/strangulated respectively. Add-on code 49623 reports removal of total or near-total non-infected mesh at the time of any of these repairs.

Mapping a 49585 repair to the new codes

Most repairs that would once have been billed as 49585 now map to 49591, 49593 or 49595. The defect size in the operative note decides which one.

Approach no longer changes the code. A laparoscopic repair converted to open takes the same code as either approach alone. The operative note should still record the conversion and its reason. Three other facts in the note do pick the code, and the path below shows them in order.

How to measure total defect size

The size band is the step most likely to go wrong, because 49585 never asked for it. The CPT measuring rules, as summarized by the American College of Surgeons, work like this:

• Measure the defect before it is opened, since the fascia typically retracts during the repair.
• Measure in either the transverse or the craniocaudal dimension, using the larger figure.
• For one defect, or several close together, measure the width or height of an oval drawn around the outer edge of all repaired defects.
• For defects separated by 10 cm or more of intact fascia, add each defect’s measurement together.
• Report one code per session, based on the total size. If any repaired hernia is incarcerated or strangulated, report the whole repair at that higher severity.

If the operative note gives no defect size, the claim can only support the smallest size band. That makes the measurement a revenue issue as well as a coding one.

ICD-10 diagnosis codes for umbilical hernia repair

The ICD-10-CM codes for umbilical hernia split by complication status, which lines up with the reducible versus incarcerated/strangulated split in the procedure codes.

K42.9 is the usual pairing for a routine elective repair of a reducible hernia. K42.0 also indexes incarcerated and irreducible umbilical hernias without gangrene, so it rarely fits a reducible repair code. When the diagnosis and the procedure code disagree on presentation, payer edits may flag the claim for review.

Reconcile both codes against the operative note before you submit. A K42.1 diagnosis points to a strangulated hernia, so it pairs with an incarcerated or strangulated repair code. When the same session repairs a ventral, incisional or epigastric hernia, report those defects with their own K43 diagnosis codes.

Modifiers for umbilical hernia repair claims

Standard surgical modifier rules apply to both the deleted 49585 and the 2023 codes. The shorter global period changes how often some of them come up.

CMS NCCI edits exist between hernia repair codes and some concurrent abdominal procedures. Before billing a repair alongside another abdominal code on the same date of service, check the specific edit pair in the current NCCI table. Modifier 59 or an X-modifier overrides an edit only when the clinical scenario supports a distinct service.

Documentation requirements for hernia repair claims

The operative note has to support every element the new codes are built on. Payers reviewing hernia repair claims look for these details, and a missing one can lead to a denial or a records request.

• Total defect size: Record it in centimeters, measured before the defect was opened. It decides the size band.
• Presentation: State whether each hernia was reducible, incarcerated or strangulated. It decides the severity half of the code.
• Initial or recurrent: Note any prior repair at the same site, since a recurrent repair uses 49613-49618.
• Mesh: Record whether mesh was placed or removed. Placement is included in the code, while removal of non-infected mesh adds 49623.
• Approach: Record the approach and any conversion. It no longer changes the code, but it belongs in the clinical record.

Local coverage determinations from your Medicare Administrative Contractor may add criteria, so check your MAC’s current policy for hernia repair. Pabau, the practice management platform we build, includes claims management software that scrubs every claim for missing or invalid details before it leaves the practice. Its Claim.MD clearinghouse connection adds eligibility verification before the visit.

Reimbursement and global period: 49585 vs the 2023 codes

Medicare pays each code from its relative value units (RVUs) in the Medicare Physician Fee Schedule. The RVUs are multiplied by the annual conversion factor and adjusted by your locality’s geographic practice cost index (GPCI). RVUs and the conversion factor change each year, so look up current values in the CMS Physician Fee Schedule lookup tool.

Facility rates for a hospital outpatient department or an ambulatory surgery center are lower than non-facility rates, because the facility bills its own costs separately. Medicare Advantage and commercial plans pay according to their own contracts, so verify each plan’s rate for the new codes.

The global period changed with the codes. 49585 carried a 90-day global period, which bundled these services into the surgical fee:

• Routine postoperative office visits
• Wound checks and dressing changes
• Suture or staple removal
• Standard postoperative pain management by the operating surgeon

The 2023 codes, 49591-49596 and 49613-49618, carry a 0-day global period. After the day of surgery, postoperative E/M visits are separately reportable under these codes. Update any follow-up visit rules your practice built around the old 90-day window, or those visits go unbilled.

For teams reconciling payments, Pabau settles insurer payments from electronic remittance advice files in the US. The guide to electronic remittance advice processing shows how that workflow operates, from the remittance file to the posted payment.

Common denial reasons for umbilical hernia repair claims

Several common hernia repair denials since 2023 trace back to the code change itself. Each one below can be prevented before submission.

When a hernia repair claim is denied, the appeal depends on the reason. The CARC and RARC codes on the remittance state that reason, and a guide to decoding denial codes explains each one.

For a deleted-code denial, submit a corrected claim with the right 2023 code. For a medical necessity denial, attach the operative note with the size and presentation highlighted. Pabau’s guide to denial management in healthcare covers the full appeal workflow.

How Pabau supports hernia repair billing

The 2023 change moved the code decision into the operative note: defect size, presentation and repair history now pick the code. Practices that still handle claims by hand lose time at each handoff between the note, the coder and the clearinghouse.

Pabau keeps the note, the code and the clearinghouse submission in one system, so a claim error surfaces before the payer sees it.

• Claim validation: Pabau scrubs every claim for missing or invalid details before it leaves the practice.
• Authorization tracking: Each insurer authorization is stored as a case, and the authorization code carries through to the claim. Claims missing one are flagged to assign a case.
• Clearinghouse submission: Pabau submits CMS-1500 claims through Claim.MD, in line with the clean claim workflow, and verifies eligibility before the visit.
• Rejection handling: Rejected claims are flagged as needing action, with a fix link to the field that needs correcting.

For the compliance side of surgical billing, Pabau’s guide to medical billing compliance covers how to keep coding policies current as code sets change.

Conclusion

CPT code 49585 belongs to claims for repairs performed before 2023, and nowhere else. For any repair since, the work is reading the operative note correctly: initial or recurrent, total defect size, and reducible or incarcerated. Get those three facts into the note at the time of surgery, and the right code from 49591-49596 or 49613-49618 follows.

Pabau scrubs claims for missing or invalid details, tracks authorizations and submits through Claim.MD. A coding error gets caught before it costs you a denial. To see how it works for a surgical practice, book a demo.
