CPT Code 45550: Every surgical specialty should care about proper cpt coding. It impacts claim approval, compliance and the amount a practice gets paid. The devil is in the details of colorectal surgery.
One such significant code is CPT 45550. It is short for partial proctectomy (removal of part of the rectum) and rectopexy (attaching the remaining rectum so it doesn’t prolapse).
This is a more complex operation than a straight forward rectopexy. Insurers routinely scrutinize claims for this code. Strong, straightforward documentation can help prevent denials and payments from being delayed.
1) What Is CPT Code 45550?
Official CPT description: Proctectomy, parietal; with rectopexy.
In plain language, the surgeon takes out a section of the rectum and then staples down what is left so it doesn’t shift.
Why surgeons perform it:
- Rectal prolapse repair: Keeps rectum from sliding forward.
- Significant rectal disease: Like diverticulitis, tumors or a redundant (extra-long) rectum.
- Alternative to total proctectomy: If you require only partial removal of the rectum and not the entire organ.
Through a single operation of resection and fixation, the patients can be spared two operations.
2) When to Use CPT code 45550
When to Bill CPT 45550:
- A partial proctectomy was performed.
- A concomitant rectopexy was performed at the time of the surgery.
- The patient has some rectal prolapse and the distal rectum or sigmoid colon is diseased.
Do not use this code when:
- If only rectopexy is performed → Then use CPT 45540.
- Total removal of the rectum → 45110 or 45112.
- If the surgeon does a sigmoidectomy with rectopexy, but no proctectomy → Use 45130 or 45135.
A code selected in error might result in denials or underpayment.
3) Documentation Requirements
The following criteria must be met and documented in the operative note for compliance/pay :
- Extent of proctectomy: Should specifically state “partial,” not total.
- Type of rectopexy performed: Explain how the rectum was attached.
- Cause for performing surgery: For example prolapse, tumour, or extreme constipation.
- Type of surgery: Abdominal or other.
- Pathology Tumor, inflammation or redundancy should be described.
- Supporting ICD-10 codes:
- K62.3 – Rectal prolapse
- D12. 8 – Benign neoplasm of rectum
- K63. 89 – Other disorders of intestine
Such details can justify medical necessity and the complexity of the case.
4) Reimbursement Insights
It was explained that CPT 45550 has more RVUs as compared to simple rectopexy or partial colectomy. And that means better reimbursement — so long as the documentation speaks for itself.
- Medicare: Coverage will be extended for this code once the operative report demonstrates a partial resection and rectopexy were performed.
- Private payers: Some may demand prior authorization, especially for prolapse- and tumor-related instances.
Common denial reasons include:
- Rectopexy was not described in the operative report.
- The note only says “sigmoidectomy,” leading to the wrong code ghostdoc pro kostenloser downloaden musik.
- Trying to charge for rectopexy as a separate procedure (it’s part of 45550).
Coders should also review payer bundling edits so that conflicting colorectal codes can be avoided.
5) Common Coding Mistakes
Some say the denials are the result of little more than simple mistakes. Avoid these:
- Mistaking 45550 and 45540: Keep in mind that, with 45540 you’re just doing rectopexy — there’s no proctectomy.
- Mistake: Using 45130 or 45135 These involve rectopexy with sigmoidectomy or levatorplasty but not a partial proctotectomy.
- Unbundling rectopexy: You’re Already Being Paid For It In 45550.
- Lack of appropriate diagnostic codes: Connect ICD-10 codes that support both resection and fixation.
These errors can result in less pay or a flat-out no.
6) Best Practices for CPT code 45550
Run through this handy checklist quickly before you bill:
- Ensure the operative note reads: “partial proctectomy performed.”
- Record rectopexy details If a laparoscopic ventral rectopexy is performed, this may also be recorded.
- Code the right ICD-10 (prolapse, tumor, redundancy).
- Investigate payer specific bundling, and edit rules.
- Scrub pre-op, post-op and op notes to ensure consistency.
Clean, comprehensive reporting minimises claim reviews and payment delays.
Conclusion
CPT 45550 represents integration of two procedures: partial proctectomy with rectopexy.
Once you know how to properly code it, your practice is in compliance and will not have costly denials. Colorectal is one of those complex claims that payers scrutinize, so it’s critical to document clearly and appropriately.
By verifying recommendation procedure details, confirming a match of diagnoses and following payer guidelines, you are able to eliminate delays and ensure appropriate reimbursement.

FAQs
Q: What does CPT Code 45550 represent in colorectal surgery?
A: It generally describes partial resection of the rectum with rectopexy, typically for prolapse or disease,
Q: How is CPT 45550 unlike 45130 and 45135?
A: 45550 includes partial proctectomy. There is no mention of proctectomy, whereas sigmoidectomy or levatorplasty with rectopexy are described for Cases 45130 and 45135.
Q: What are some other diagnoses that can be billed with CPT code 45550?
A: Rectal prolapse (K62. 3), benign rectal tumor (D12. 8) and other diseases of rectum (K63. 89).
Q: Is CPT 45550 reimbursed by Medicare for rectal prolapse?
A: Yes — providing the OP report demonstrates both partial resection and rectopexy.
Q: Why are CPT code 45550 denials so prevalent?
A: Lack of rectopexy information, inappropriate code selection, or failure to attach the correct diagnosis.
