Septal Cartilage Graft and Septoplasty

Question:

My doctor did a septoplasty, CPT 30520, removed cartilage and fashioned it for a graft that he used in the surgical repair of vestibular stenosis, CPT 30465. Can we also code 20912 for the fashioning of the graft or just 30520 and 30465? I couldn’t find any CCI edits preventing this.

Answer:

Only one code, 30520 or 20912, may be reported as these procedures were performed through the same incision. What was the reason for the incision – to straighten the septum (30520) or to obtain the graft (20912)? Use whichever code is supported by the documentation but do not use both codes. .

Excisional Biopsy

Question:

My doctor’s documentation for a biopsy indicates he performed an “excisional biopsy of the skin”. Is this correct?

Answer:

No, CPT does not have a code for excisional biopsy. It is either a biopsy (11100 or 11101) or a benign or malignant excision code. (114xx, 116xx). It is important to use the appropriate terminology in the documentation to make it clear what type of procedure is performed. It is important to remember that all excision codes include a biopsy.

Pharyngoplasty With Free Flap Reconstruction

Question:

I’m doing the repair of the oral cavity defect with a free flap reconstruction after the head and neck surgeon has resected the cancer. Can I code both 42950 and the free flap code such as 15758?

Answer:

The free flap codes include the harvest, inset, microvascular anastomosis, and closure of both donor and recipient site defects. You may separately code the harvest of graft material through a separate incision (e.g., split thickness skin graft) to facilitate the donor defect closure. So the answer is no, it is not accurate to separately code for a pharyngoplasty when you are insetting the free flap.

A CPT Assistant article from April 2016 addresses this situation in great detail.

Question:

Is code 42950, Pharyngoplasty (plastic or reconstructive operation on pharynx), reportable in addition to code 15757, Free skin flap with microvascular anastomosis, when a free flap is used to reconstruct both a neck and tongue defect (after laryngectomy or glossectomy)? The microvascular free flap is de-epithelialized and the skin paddle is used to complete the pharyngeal closure. The rest of the flap is used to complete the esophageal closure.

Answer:

No, CPT code 42950 should not be reported in addition to code 15757, when a free flap is used to reconstruct both a neck and tongue defect (after laryngectomy or glossectomy). The intraservice work of code 42950 is encompassed in code 15757, which includes harvesting a donor free flap, insetting the free flap at the recipient site using microsurgical technique, and closure of both donor and recipient sites. The pharyngeal reconstruction should be included in code 15757, as it would for wherever the flap was inserted. In addition, the inclusion of the flap closure should be considered as part of the work included in the basic closure of the primary resection site. This basic closure is inclusive of code 15757.

Diagnosis Code for Laryngopharyngeal Reflux

Question:

I’m getting used to ICD-10-CM! Thanks so much for teaching me about it. I do have a question though. I can’t seem to find a diagnosis code for laryngopharyngeal reflux. What do you suggest?

Answer:

Actually, we’ve always suggested using K21.9, Gastro-esophageal reflux disease without esophagitis. Coincidentally, in a recent issue (first quarter 2016) of the American Hospital Association’sThe Coding Clinic, the same advice was provided.

Tympanostomy Tube with Intratympanic Injection

Question:

I did an intratympanic steroid injection and coded 69801 and 69433. Medicare paid 69801. Should I appeal the denial of 69433?

Answer:

No! CPT 69801 says Labyrinthotomy, with perfusion of vestibuloactive drug(s); transcanal. The CPT guidelines say: Do not report 69801 in conjunction with 69420, 69421, 69433, 69436 when performed on the same ear. By billing 69801 and 69433, for procedures on the same ear, you’ve unbundled the codes. The denial is accurate so you should not appeal. Furthermore, in the future, do not bill 69433 or 69436 (tympanostomy tube placement) or 69420 or 69421 (myringotomy) for the same ear when you also report 69801.

Repair of Nasal Vestibular Stenosis

Question:

I am trying to come up with the right CPT codes for a repair of nasal vestibular stenosis so we can get it pre-certified. Can you help?

Answer:

Yes, you are wise to determine the correct codes for pre-certification, otherwise the surgery might not be paid if you billed different codes.  Look at 30465 – Repair of nasal vestibular stenosis (e.g., spreader grafting, lateral nasal wall reconstruction).  You may also report a separate code if you harvest graft material through a separate incision.  For example, you may report 20912 (Cartilage graft; nasal septum) if you harvest septal cartilage graft when you have not performed a septoplasty at the same operative session.  If you did a septoplasty (30520) and repair of nasal vestibular stenosis (30465) then you may not report 20912 for the septal cartilage graft harvested/obtained from the septoplasty.
