Q: Can you explain when a neoplasm should be listed as the principal diagnosis? We have some coders who believe the neoplasm should always be the principal diagnosis.
Q: A patient presents with lower back pain and the physician documents findings of stenosis, degenerative “changes,” and mild facet arthropathy. Which diagnosis codes should we report? I would code 724.02 (stenosis, lumbar region, without neurogenic claudication) and 721.3 (lumbosacral spondylosis without myelopathy) for the facet degeneration. Another coder has stated that I cannot code 724.02, as the 721.3 diagnosis code will exclude the use of 724.02. Can you help with this scenario?

Q: When we send in a claim for CPT ® code 29898 (arthroscopy, ankle, surgical; debridement, extensive) to Aetna with modifier –AS (non-physician assisting at surgery) for our physician’s assistant, Aetna will deny the claim saying “assistant not covered.” However, that procedure code says it is covered for an assistant surgeon. I have sent appeal after appeal and printouts from the American College of Surgeon’s (ACOS) Coding Today website showing this procedure code is payable to Aetna, and Aetna still denies the claim. Medicare pays on this claim, why wouldn’t Aetna?
Q: In ICD-10-PCS, which root operation would we report for an obstetrical delivery? Would it change for a cesarean section versus a manually assisted vaginal delivery?
Q: How does CPT ® define "final examination" for code 99238 (hospital discharge day management; 30 minutes or less)? Does the dictation have to include an actual detailed examination of the patient? We have been coding 99238 for discharges that include final diagnosis, history of present illness, and hospital course along with discharge labs, medicines, and home instructions. Very few contain an actual exam of the patient. Have we been miscoding all this time?
Q: Can you ask a yes or no question in a query based on clinical information from a previous echocardiogram report or other diagnostic result from a previous admission?
Q: When a procedure is performed by laparoscopy, but only a code for the open approach is listed, do you use the unlisted procedure code? For example, the physician documented: laparoscopic pyloromyotomy, hypertrophic pyloric stenosis. We used CPT ® code 43520-22 (pyloromyotomy, cutting of pyloric muscle, Fredet-Ramstedt type operation, with the increased procedural services modifier) but the coding department corrected with 43659 (unlisted laparoscopy procedure, stomach). We are a pediatric surgical practice. I feel because the procedures are very common and performed often, our revenue will drop by using unidentified procedure codes, but I want to code them correctly.
Q: What recommendation would you give to the coder when the clinical indicators in the chart do not support sepsis but it’s in the final diagnostic statement?
Q: We recently had a situation where a patient had come in to have his port re-assessed. He had been complaining of the port being difficult to access. Preliminary x-ray showed the port accessed, with great blood return. Patient has an allergy to IV contrast, so we just flushed the port, and did not give the contrast. The port remained accessed. How do we code this? Do we use 36598 (contrast injection[s] for radiologic evaluation of existing central venous access device, including fluoroscopy, image documentation and report) with a modifier -52 (reduced services)? The other option is a modifier -73 (discontinued outpatient procedure prior to anesthesia administration) or -74 (discontinued outpatient procedure after anesthesia administration). However we have no documentation regarding anesthesia, and I'm not sure the patient would even get anesthesia for a procedure such as this.

Q: The patient has had a previous bilateral mastectomy and is now coming in for a revision of bilateral areola with a dermal fat graft to the left nipple and excision of excessive skin and subcutaneous tissue from both breasts. This would be CPT ® code 19380 (revision of reconstructed breast) with modifier -50 (bilateral procedure) and 19350-50 (nipple/areola reconstruction) for both procedures. I cannot locate information that tells me if the nipple revision on the reconstructed breast is part of the 19380 or can be separately coded with 19350.

Q: A patient presents with altered mental status/encephalopathy due to a urinary tract infection (UTI). The patient has a history of dementia. The final diagnosis is encephalopathy due to UTI. Should we code the encephalopathy as a secondary diagnosis because it’s an MCC and not always a symptom of a UTI?
