CPT Code 10140: Incision and drainage of hematoma, seroma, or fluid collection

Key takeaways

CPT Code 10140 covers incision and drainage of a hematoma, seroma, or non-purulent fluid collection.

Abscess drainage belongs to CPT 10060 or 10061, so the fluid named in the note decides the code.

The 2026 Medicare national average runs roughly $165 to $200 in an office and $55 to $75 in a facility.

A 10-day global period bundles routine follow-up visits, wound checks, and drain removal into the procedure payment.

Practice management software like Pabau links the procedure note to the claim, so documentation and modifiers stay aligned.

CPT Code 10140 covers incision and drainage of a hematoma, seroma, or other non-purulent fluid collection. It sits in the integumentary section of the AMA CPT code set. The abscess codes 10060 and 10061 are a separate family. The fluid your operative note names decides which code goes on the claim.

Below you’ll find the official AMA description, the 2026 Medicare reimbursement rates, and the modifiers that apply. The 10-day global period, the ICD-10-CM crosswalk, and the documentation elements that support a clean claim follow after that.

Dermatology, plastic surgery, and urgent care teams bill 10140 most often, in offices, outpatient departments, and minor procedure rooms. Practices at that volume usually track it inside their skin clinic software alongside every other integumentary procedure.

What CPT Code 10140 covers

CPT Code 10140 is the right code when a clinician surgically opens and drains a collection of blood, serous fluid, or other non-purulent fluid. Those are the hematoma, seroma, and fluid collection named in the code description. In the AMA CPT codebook it sits under “Incision and Drainage Procedures on the Integumentary System.”

The procedure means making a surgical incision over the fluid collection and evacuating the contents. A drain or packing usually goes in afterward to stop the collection re-forming. It comes up most in post-operative hematoma, in trauma, and in soft tissue injury that develops a seroma.

The AMA CPT code set keeps 10140 separate from the abscess drainage codes. Mixing the two families is the most common source of 10140 denials.

CPT 10140 fee schedule and reimbursement rates (2026)

Medicare reimbursement for CPT Code 10140 depends on the place of service. Non-facility rates in an office are higher because they include practice expense for equipment and staff. Facility rates in a hospital outpatient department or ASC are lower, because the facility bills its own fee separately.

The figures below are 2026 national averages. Check them against the CMS Physician Fee Schedule lookup tool for your own payment locality before you bill. Every rate is adjusted by a Geographic Practice Cost Index multiplier, so the national figure is only a starting point.

Practices that also bill UK private insurers work from a separate procedure code fee schedule, so US figures do not carry across.

RVU breakdown for CPT 10140

Relative Value Units, known as RVUs, are the building blocks of Medicare reimbursement. Each CPT code carries three RVU components. Those get multiplied by a conversion factor and a geographic adjuster to produce the final payment. The FastRVU 2026 lookup returns the current values for 10140 in your locality.

Modifiers for CPT code 10140

Modifier use with CPT Code 10140 is payer-specific. The National Correct Coding Initiative, known as NCCI, governs the bundling rules. Individual Medicare Administrative Contractors can also publish local coverage determinations that restrict or require particular modifiers. Check both before you submit.

Global period for CPT 10140

CPT Code 10140 carries a 10-day global period. Knowing what that covers prevents overbilling and explains why some follow-up claims are denied. The window also matters when the drainage follows a larger operation such as 19380. That parent procedure carries its own global period, and it governs which modifier you need.

• What is bundled: All routine post-procedure evaluation and management visits related to the I&D during the 10-day window sit inside the global package. These cannot be billed separately.
• What is not bundled: An E&M visit for a distinct, unrelated diagnosis on the same day is billable with modifier 25. A complication that sends the patient back to the procedure room is billable with modifier 78. A service for a new or unrelated condition takes modifier 79.
• Same-day E&M: If the decision to treat was made at that visit, the E&M before the procedure can be billed with modifier 25. The documentation has to support a separately identifiable visit.
• Follow-up within 10 days: Do not bill a standard office visit for wound checks or drain removal inside the global period. Those are bundled.

ICD-10-CM codes commonly used with CPT 10140

Pairing the right ICD-10-CM diagnosis code with CPT Code 10140 is what establishes medical necessity. Payers cross-reference the two. If the diagnosis points to an abscess rather than a hematoma or seroma, the claim will usually deny.

For a traumatic collection, reach for the specific injury code, such as S33.4XXD. The CDC ICD-10-CM tool confirms whether you are using the most specific code available.

Always use the most specific code available. ICD-10-CM updates every October 1, so confirm the codes above are current for the fiscal year of service on the CMS ICD-10 codes page.

How CPT 10140 compares to the other I&D codes

The I&D family is small and often misapplied. CPT Code 10140 is one of four closely related codes, each tied to a specific clinical picture. Picking 10060 when 10140 is correct triggers a medical necessity denial, because the diagnosis on the claim will not match the procedure.

CPT 10060 vs 10140: key differences

The line between 10140 and 10160 matters most for seroma drainage. Needle aspiration with no incision is 10160, and image-guided aspiration moves you into codes like 10012. A scalpel incision is what puts you in 10140. Billing one when the other was performed creates a mismatch between the note and the claim, which payers catch in post-payment audits.

Documentation requirements for CPT code 10140

Clean documentation prevents denials and carries the medical necessity review. For CPT Code 10140, the operative or procedure note has to capture specific clinical elements. A note that says only “I&D performed” will not survive a request for records. Practices working to HIPAA-compliant documentation standards should make sure those workflows capture every element below at the point of care.

• Clinical indication: Name the type of fluid collection, whether hematoma, seroma, or another non-purulent collection, and its anatomical location.
• Presentation findings: Describe the size, fluctuance, and overlying skin appearance, plus any pain, limited range of motion, or wound dehiscence.
• Procedure performed: State that an incision was made, name the instrument, and record the depth of drainage and the volume of fluid evacuated.
• Drain or packing: Note whether a wound drain, wick, or packing was placed, and the plan for removing it.
• Post-procedure plan: Record the wound care instructions, the follow-up timing, and any antibiotic therapy prescribed.
• Medical necessity statement: Say briefly why drainage was clinically necessary, such as an expanding post-operative hematoma causing wound tension.

The standard is the same across integumentary procedures. It holds for a lesion excision like 11622 and for a layered repair like 13120. In every case the note has to let a non-reviewing clinician see exactly what was done and why.

Procedure-specific templates and digital intake forms can pre-populate those fields at the point of service. That keeps the note complete without extra typing after the list is closed.

Common denial reasons and how to avoid them

CPT Code 10140 denials follow predictable patterns. Most trace back to one of four things: wrong code selection, thin documentation, a global period conflict, or a missing modifier. A pre-submission checklist that covers all four raises your clean claim rate.

How practice management software streamlines CPT 10140 billing?

Billing 10140 means holding several rules in your head at once: global periods from earlier surgeries, payer-specific modifier requirements, and ICD-10 crosswalk accuracy. Doing that manually at volume produces errors. Claims management software inside a practice management platform builds the coding rules into the workflow. A single coder is no longer the last line of defense.

Pabau’s practice management software lets integumentary and surgical practices build the documentation and billing steps around procedures like 10140. Structured procedure note templates feed straight into the claims workflow, so fewer details are lost between the treatment room and the claim.

Practices running plastic surgery EMR workflows see post-operative hematoma drainage often. In Pabau they can link the original surgical encounter to the 10140 claim inside the client record, which is what modifier 78 review depends on.

The value of practice management tools in claim accuracy goes past code lookup. Tracking which patients sit inside a global period, flagging a follow-up visit that needs a modifier, and working a denial queue are all workflow jobs. On a procedure-heavy schedule they are where revenue leaks stop.

Conclusion

If you take one habit away from this page, make it naming the fluid in the operative note before anyone touches the claim form. That single line decides the code, the diagnosis pairing, and whether the claim survives a records request. Everything else here is downstream of it.

The trade-off worth remembering is the 10-day global period. It buys you a simpler follow-up schedule and costs you the ability to bill routine wound checks. Build the visit plan around that rather than fighting it afterward. Practices that template the note and audit before submission spend far less time on appeals.
