CPT code 49322 – Laparoscopic aspiration of cavity or cyst

Key takeaways

CPT code 49322 covers laparoscopic aspiration of any abdominal or pelvic cavity or cyst, and it is billed once per session however many are drained.

CPT 49320, diagnostic laparoscopy, is bundled into 49322 by NCCI edits and cannot be billed in the same operative session.

Modifier -59 is required when billing 49322 with CPT 58661, removal of adnexal structures (oophorectomy and/or salpingectomy). The operative report must support a distinct aspiration service.

49322 carries a 10-day global period, so related post-operative visits in those 10 days are included in the surgical payment.

Claims software such as Pabau flags NCCI edit pairs and missing modifiers before submission, which cuts denials on gynecologic laparoscopy claims.

CPT code 49322: Official descriptor and code family

CPT code 49322 is the surgical laparoscopy code for aspirating a cavity or cyst, such as an ovarian cyst. Its official descriptor, maintained by the American Medical Association, reads: Laparoscopy, surgical; with aspiration of cavity or cyst (eg, ovarian cyst) (single or multiple). It sits in the CPT surgery section, in the laparoscopy and peritoneoscopy range 49320 to 49329.

The “(eg, ovarian cyst)” parenthetical gives one example. The code also covers aspiration of any abdominal or pelvic cavity, cyst, or fluid collection approached laparoscopically. The “(single or multiple)” wording sets the unit rule. The code is billed once per operative session, however many cysts or fluid collections were aspirated.

CPT 49322 vs CPT 49320: Key differences

CPT 49320 is diagnostic laparoscopy only. CPT 49322 is surgical laparoscopy with aspiration. When a surgeon enters the abdomen and aspirates a cyst in the same session, only 49322 is billable. The National Correct Coding Initiative treats 49320 as a component of the more extensive surgical code, so submitting both triggers an automatic denial on 49320.

When to use CPT 49322: Covered procedures and clinical scenarios

CPT code 49322 is appropriate when the surgeon performs laparoscopic aspiration as the primary therapeutic intent of the procedure. Gynecologic and general surgery practices see this code regularly. The most common clinical scenarios include:

• Ovarian cyst aspiration (functional, follicular, corpus luteum, or paraovarian cysts)
• Peritoneal cavity fluid aspiration (ascites sampling or therapeutic drainage via laparoscope)
• Pelvic cyst or hematoma aspiration when approached laparoscopically
• Multiple cyst aspirations performed in the same session (billed as one unit)

What 49322 does not cover: Laparoscopic cystectomy or excision (where the cyst wall is removed) maps to a different code. Drainage of an intra-abdominal abscess uses a separate code family. If the operative report documents removal of ovarian tissue rather than aspiration alone, 49322 is not the correct code.

CPT 49322 and CPT 58661: Coding together in gynecologic laparoscopy

CPT 58661 covers laparoscopic removal of adnexal structures (oophorectomy and/or salpingectomy). It can be billed with 49322 when a distinct aspiration happens separately from the adnexal removal. By default, NCCI edits treat 49322 as a column 2 component of 58661, because aspiration is often inherent to the removal. Modifier -59 overrides this edit when the aspiration is a separate service.

The operative report must place the aspiration at a separate anatomical site, on a different cyst, or before the decision to remove the adnexa. Without that documentation, modifier -59 carries audit risk. Similarly, CPT 58662 (laparoscopic fulguration or excision of lesions) carries a related bundling relationship with 49322 requiring the same distinct-procedure justification.

Submission order for paired codes

Bill 58661 as the primary code and 49322-59 as the secondary when submitting both. Some payers require the higher-RVU code in the primary position, so confirm your payer’s rules before claim submission.

Modifiers for CPT code 49322

Correct modifier use on CPT code 49322 claims prevents the most common denials. Accurate superbill preparation should flag modifier requirements before the claim leaves the practice. The modifiers applicable to this code are:

ICD-10 diagnosis codes commonly linked to CPT 49322

Payers cross-reference the diagnosis code against the procedure to confirm medical necessity. For CPT code 49322, the ICD-10-CM codes below are the most commonly accepted on claims. Specificity matters. Selecting an unspecified code when the operative report documents laterality is a common audit finding.

Always verify diagnosis code pairing against the applicable Medicare Administrative Contractor (MAC) Local Coverage Determination (LCD) for your region. Some MACs restrict 49322 to specific ICD-10 codes under their gynecologic laparoscopy LCD. Look each diagnosis up in our ICD-10-CM codes library to confirm its full descriptor before you finalize the claim.

Documentation requirements for CPT 49322

The operative report is the single most important document for defending CPT code 49322 claims. Building a habit of medical billing compliance around documentation starts at the time of service. A report that will support 49322 on audit must include:

• Laparoscopic approach confirmed: Surgeon’s entry method, port placement, and camera visualization documented
• Cyst or cavity identified: Description of the structure aspirated, including anatomical location and laterality
• Aspiration performed as primary intent: The report must show aspiration was the planned therapeutic procedure. A cyst seen incidentally and aspirated as an afterthought does not meet this bar.
• Aspirate description: Volume, color, and character of fluid removed (serous, hemorrhagic, mucinous)
• Specimen disposition: Whether fluid was sent to pathology or discarded
• Distinct service justification: If modifier -59 was applied, the report must explain why the aspiration was separate from any concurrent procedure

Submitting a clean claim for this code depends on the operative report being finalized before submission. Billing from incomplete notes is the root cause of most 49322 audits.

Medicare and payer reimbursement for CPT 49322

Medicare reimbursement for CPT code 49322 is determined by the Medicare Physician Fee Schedule (MPFS), maintained by the Centers for Medicare and Medicaid Services. Use the CMS Physician Fee Schedule lookup tool to pull current-year rates for your geographic practice area, as rates vary by locality and change annually.

Under the 2026 MPFS, CPT 49322 carries the same RVUs in facility and non-facility settings:

The 10-day global period covers the day of the procedure plus 10 post-operative days. Related post-operative services in that window are included in the surgical payment and are not billed separately without a modifier. Commercial payer rates vary and may sit above or below Medicare. Prior authorization is increasingly common for elective gynecologic laparoscopy, so confirm it before scheduling.

Bundling rules and NCCI edits for CPT 49322

The National Correct Coding Initiative (NCCI) governs which code pairs can be billed together and which are automatically bundled. For CPT code 49322, the most consequential edit pairs involve 49320 and 58661. Pre-claim scrubbing in claims management software flags these edit pairs before submission. The key NCCI relationships are:

NCCI edit tables update quarterly. Always verify the current modifier indicator in the CMS NCCI procedure-to-procedure edits before submitting complex multi-procedure claims. A modifier indicator of 0 means no modifier can override the bundle under any circumstances.

Put together, these edits reduce to three billing paths, and the operative report decides which one applies.

Common claim denial reasons for CPT 49322 and how to appeal

Most CPT code 49322 denials fall into a short list of avoidable root causes. A structured denial management workflow should address each of these before claims leave the practice:

• Missing modifier -59 with 58661 or 58662: NCCI bundling kicks in automatically. Appeal with the operative report highlighting the distinct aspiration service and append -59 on resubmission.
• CPT 49320 billed in the same session: Payers deny 49320 as a component of 49322. Remove 49320 from the claim and resubmit 49322 alone.
• Inadequate operative report: Payers request records when the report does not explicitly describe aspiration as the primary surgical intent. Complete the report before initial submission.
• Medical necessity not supported by ICD-10: An overly nonspecific ICD-10 code (or one not on the payer’s LCD) triggers medical necessity denial. Match the diagnosis code to the operative findings with appropriate laterality.
• Billing 49322 as an add-on code: 49322 is a standalone code. Billing it as a secondary or add-on code without a primary is an automatic rejection.
• Global period conflict: Related post-operative services billed separately within the 10-day global window are denied. Check the procedure date before billing any follow-up encounter in the same surgical period.

How claims management software prevents CPT 49322 denials

Without a scrubbing step, a coder checks each 49322 claim against the NCCI tables by hand, often only after a denial comes back. Fixing it then means reworking the claim, attaching the operative report, and waiting another payment cycle.

Pabau, the practice management platform we build, runs that check before the claim leaves the practice. Its claims tools flag the 49320 bundle and a missing -59 on a 58661 or 58662 pairing while the claim is still a draft. US practices then submit through the Claim.MD clearinghouse integration and track each claim to payment.

The result is fewer resubmissions on gynecologic laparoscopy claims, and faster payment for surgery your team has already performed.

Conclusion

Billing CPT code 49322 cleanly comes down to one habit. Read the operative report before you choose the codes. If it shows aspiration alone, bill 49322 once and leave 49320 off the claim. If it shows adnexal removal or fulguration as well, add -59 only where the report places the aspiration at a separate site or cyst.

Coders who build that check into charge entry trade a few minutes per case for fewer appeals and a cleaner audit trail. The trade-off is strict discipline with -59, which payers watch closely.
