CPT code 99024 documents a postoperative follow up visit that falls inside a patient’s global surgical package. It does not carry a dollar value on its own. Practices report it anyway, and the reason matters more than most billers realize.
If you run coding for a small or mid size practice, you have probably asked whether 99024 is even worth the click. Here is the direct answer: yes, and skipping it can quietly hurt your reimbursement rates down the road.
What Does CPT Code 99024 Cover?
CPT 99024 reports an evaluation and management service performed during a postoperative period for a reason connected to the original procedure. Think wound checks, suture removal, dressing changes, and routine recovery assessments. These visits sit inside the global surgical package, so they generate no separate payment.
The code exists for tracking, not billing. Payers already assume these visits happen when they price a procedure’s global period. CPT 99024 gives them the data to confirm that assumption.
Why CMS Cares About 99024 Reporting
CMS uses 99024 submission rates as claims based evidence of how often postoperative visits actually occur. When practices skip the code, CMS sees fewer reported visits than expected. Fewer reported visits can lead CMS to conclude that a procedure’s global period includes more visit value than it should, which opens the door to reduced reimbursement for that procedure over time. Consistent coding accuracy here connects directly to how your revenue cycle management performs over the long term.
CMS requires certain practitioners, including specific high volume group practices in select states, to report 99024 during defined data collection windows. Even outside a mandatory reporting state, submitting the code protects the accuracy of the data CMS uses to value your procedures. See the Medicare Claims Processing Manual for the CMS definition of the global surgical package.
Medical coding
Missed postoperative visits and inconsistent CPT reporting quietly erode your procedure valuations over time. Our Medical Coding Services team builds coding workflows that catch codes like 99024 before claims go out, so your data accurately reflects the care you deliver.
When Should You Report CPT 99024?
Report 99024 any time a postoperative visit meets two conditions. First, the visit falls within the assigned global period for the original procedure. Second, the care provided is routine recovery work directly tied to that procedure, not a new or unrelated problem.
If a patient comes in during the global period for something unrelated to the surgery, that visit gets billed separately using the appropriate E/M code with modifier 24 attached. Modifier 24 signals to the payer that the visit falls outside the bundled surgical package. Mixing this up is one of the most common coding errors we see in practices without a dedicated coding review step.
99024 and the Global Surgical Package
Every procedure with a global period, whether 10 days for a minor procedure or 90 days for a major one, bundles a defined set of postoperative services into the original payment. CPT guidelines define this package one way. Medicare defines it slightly differently. The payer’s published policy governs which definition applies to a given claim, per the AMA CPT code set.
This distinction trips up a lot of practices, especially ones handling a mix of Medicare and commercial payers under different global surgery rules. Getting it wrong in either direction creates real risk. Under reporting looks like your patients skip follow up care. Over billing outside the package creates denials and, in repeat cases, audit exposure.
Common Documentation Mistakes with 99024
- Skipping the code entirely because it carries no payment, which weakens your CMS reporting profile
- Using 99024 for visits that address a new, unrelated condition instead of the correct E/M code with modifier 24
- Failing to document medical necessity for the visit, even though 99024 itself is not separately reimbursed
Documentation still matters here. A thin or missing note for a 99024 visit creates a gap in the medical record, and that gap becomes a problem the moment a payer audits the global period.

Medical coding
Every global period visit you fail to code correctly is data CMS uses to price your next procedure. Our Medical Coding Services team keeps your postoperative reporting accurate and audit ready, specialty by specialty.
The Bottom Line
CPT 99024 will never show up on your revenue report. It shows up in how CMS values your procedures for years afterward. Reporting it consistently protects your practice’s long term reimbursement, and skipping it does the opposite, quietly and slowly.
Frequently Asked Questions
Does CPT code 99024 pay separately?
No. CPT 99024 carries no monetary value. It documents a postoperative visit already bundled into the global surgical package payment for the original procedure.
When was CPT 99024 introduced?
The American Medical Association introduced CPT 99024 with an effective reporting date of January 1, 2013.
What is the difference between 99024 and modifier 24?
CPT 99024 reports a routine postoperative visit related to the original procedure. Modifier 24 attaches to a standard E/M code and reports a visit during the global period for a reason unrelated to that procedure, which allows separate billing.
Is reporting CPT 99024 mandatory?
CMS requires reporting from specific practitioners, generally larger group practices in select states, for certain high volume or high cost procedures with global periods. Outside those mandatory windows, reporting is not required but is strongly recommended for data accuracy.
Why does CMS track 99024 submissions?
CMS uses submission volume as evidence of how often postoperative visits actually happen. Low reporting volume can lead CMS to lower the value assigned to procedures with global periods, since the data suggests fewer visits occur than the payment assumes.
Does the practice setting affect 99024 reporting?
No. Report 99024 for postoperative visits performed in the office, emergency department, hospital, or skilled nursing facility, as long as the visit falls within the global period and relates to the original procedure.
