The short version
- 15876 through 15879 split by body region, not technique. Head and neck, trunk, upper extremity, lower extremity. The device in the operative note does not pick the code.
- All four carry status R and 0.00 RVUs in the 2026 Physician Fee Schedule. Medicare assigns them no payment amount, so a contract term written as a percentage of Medicare has nothing to multiply.
- The global period is 000, not 90. Post-op visits are separately billable, and a staged reduction is a series of separate procedures.
- Multiple-procedure indicator 2 applies. The second region and every region after it pays at 50 percent.
- Modifier 50 belongs on 15878 and 15879 only. The trunk and head/neck codes are not bilateral-eligible.
Four codes, split by where you worked
Four codes. The only thing separating them is where on the body you worked. 15876 head and neck, 15877 trunk, 15878 upper extremity, 15879 lower extremity.
Technique doesn’t pick the code. Tumescent, power-assisted, ultrasound-assisted, laser, whatever the rep sold the practice last quarter. It all lands in the same four codes. An operative note can describe the most advanced device in the building and the code still comes from the anatomy.
Trunk covers abdomen, flanks, and back. Two trunk sites in one session are still 15877, reported per site, with modifier 59 on the additional line. Stretching 15877 across an arm because the arm was done in the same sitting is where this goes wrong. The arm is 15878, and 15878 does not play by the same payment rules. Start from the anatomy list.
| Code | Region | Global | Modifier 50 | 2026 Medicare RVUs |
|---|---|---|---|---|
| 15876 | Head and neck | 000 | No | 0.00 |
| 15877 | Trunk | 000 | No | 0.00 |
| 15878 | Upper extremity | 000 | Yes | 0.00 |
| 15879 | Lower extremity | 000 | Yes | 0.00 |
Medicare does not price 15877
All four codes carry status indicator R in the 2026 Physician Fee Schedule relative value file. Work RVUs, practice expense, malpractice: 0.00 across the board. There is no national payment amount. Not a low one. None.
Which breaks something most practices never check. A commercial contract paying a percentage of Medicare has nothing to take a percentage of. Whatever gap-fill language sits in that agreement is your actual fee schedule here, whether that is carrier pricing, a percentage of billed charges, or a rate somebody negotiates by phone. No gap-fill language at all, and you are billing a code your own contract does not price.
The neighbors make it worse. 15830, excision of excessive skin of the abdomen, carries 31.95 total RVUs and a 90-day global. 15832, the thigh, carries 25.22 and a status of A.
Same patient population. Often the same consultation. One path has a Medicare price and the other has nothing at all.
Go find the sentence in your top three contracts that covers codes with no assigned RVU. On these cases it is worth more than the operative note.
15877 has no global period
The global period on 15876 through 15879 is 000. Zero days.
That runs against instinct, because the codes sitting right beside them do have one. 15830 and 15832 both carry 090. A practice doing excisional contouring and suction lipectomy ends up with two adjacent procedures on the same schedule following completely different post-op rules.
Three things follow from 000. Number one, post-op visits are separately billable and are not bundled into the surgical fee. Number two, a staged reduction is a series of separate procedures rather than a return inside a global window, so there is no modifier 58 argument to have. Number three, a same-day E/M can stand on its own with modifier 25 when the evaluation was genuinely separate.
Now go check what the practice management system actually has loaded. A system carrying a 90-day global on 15877 suppresses those post-op visits on its own, quietly, and nobody catches it, because the visits never reach a claim to be denied. Our global period lookup carries the current day counts.
The multiple-procedure cut, and where modifier 50 actually applies
Multiple-procedure indicator 2 on all four. The highest-valued procedure pays in full and everything after it pays at half, per the Medicare Claims Processing Manual.
Put a real case against that. Trunk plus both lower extremities is not three payments. It is one payment and two halves. Three regions of work, two regions of money. Quote the patient at full charge per region and you have promised something the claim will never deliver.
Bilateral is the line that gets miscoded most. The bilateral surgery indicator is 1 on 15878 and 15879, and 0 on 15876 and 15877. Modifier 50 goes on the extremity codes. Not the trunk. Not head and neck. Plenty of published guidance says otherwise, and an older version of this page was among it.
Estimates come off the reduced amounts. Modifier 50 loads against 15878 and 15879, nothing else.
Medical necessity gets the claim reviewed, not paid
Payers who cover lipedema reduction run a checklist: confirmed diagnosis with a stage, three months of failed conservative therapy of the right kind, documented functional impairment, a post-op compression plan. We work that checklist in why lipedema surgery gets denied as cosmetic, and the diagnostic half in lipedema vs. lymphedema.
Clear all four and you have an approval. You still do not have a rate.
Those are separate fights, and practices lose the second one constantly after winning the first. Medical necessity decides whether the claim gets looked at. The missing fee schedule decides what it is worth.
Generally speaking, in-network runs on an LOA or a single-case rate, because the contract lists no amount to fall back on. Out-of-network, it lands in the NSA lane and the QPA calculation runs against a code with no Medicare benchmark. Self-funded and out of scope, and you are negotiating off the operative note and nothing else. Sat in the billing seat, this is the one that sits in AR while everybody assumes the approval settled it.
If the surgeon is taking the direct-excision route, the coding changes completely. Lipedema excision (15832–39) has its own rules and, unlike 15877, a real price. Either way, settle the rate in writing before the date of service. An approval letter on a code Medicare prices at zero is not a payment promise.
Frequently asked questions
What is CPT 15877?
CPT 15877 is suction-assisted lipectomy of the trunk — liposuction of the abdomen, flanks, or back. It sits in the integumentary section of the CPT manual. The code is selected by body region, not by the liposuction technique or device used.
What is the global period for CPT 15877?
000 days. CPT 15876 through 15879 carry a 000-day global period in the Medicare Physician Fee Schedule, so post-operative visits are separately billable and staged sessions are separate procedures rather than returns inside a global window.
Does Medicare pay for CPT 15877?
Medicare assigns CPT 15877 status indicator R and 0.00 work, practice expense, and malpractice RVUs, so there is no national Medicare payment amount for the code. Coverage, when it exists, is handled through local coverage determinations and carrier pricing rather than a published fee schedule rate.
Can you bill modifier 50 with CPT 15877?
No. The bilateral surgery indicator is 0 for CPT 15877 and 15876, meaning the bilateral payment adjustment does not apply. Modifier 50 applies to CPT 15878 and 15879, the upper and lower extremity codes, which both carry a bilateral surgery indicator of 1.
How do you bill liposuction of multiple body regions in the same session?
Report the code for each region treated. Multiple trunk sites use CPT 15877 per site with modifier 59 on the additional lines. Because all four codes carry multiple-procedure indicator 2, the highest-valued procedure pays in full and each additional procedure pays at 50 percent.
What is the difference between CPT 15877, 15878, and 15879?
Body region. CPT 15877 is the trunk, 15878 is the upper extremity, and 15879 is the lower extremity. CPT 15876 covers head and neck. All four describe the same suction-assisted lipectomy service performed in a different anatomic area.
Is CPT 15877 covered for lipedema?
Some payers cover lipedema reduction when a documented checklist is met: a confirmed lipedema diagnosis with a stage, at least three months of failed conservative therapy such as compression or complete decongestive therapy, documented functional impairment, and a post-operative compression plan. Coverage varies by payer policy.
What is the difference between CPT 15877 and CPT 15832?
CPT 15877 is suction-assisted lipectomy of the trunk and carries no Medicare RVUs and a 000-day global. CPT 15832 is direct excision of excessive skin of the thigh, carries roughly 25 total RVUs, and has a 90-day global period. Different surgical approach, different payment rules.
This article explains how these codes tend to get paid — it is not coding, billing, or legal advice. Some of the codes here are bundled into the main procedure, or fall into grey areas that vary by payer. Before billing anything in a grey area, confirm it with your own coding and compliance team and the current guidance from the American Society of Plastic Surgeons (ASPS), Medicare (CMS), and AMA CPT. When in doubt, don’t bill it.
