Requesting assistance regarding this case. Multiple coders review and came to a road block because the provider code selections are not the same, we need additional assistance. Please!!!!

PREOPERATIVE DIAGNOSES: Left knee:
1. Medial meniscus tear.
2. Mild osteoarthritis.
3. ACL sprain.
4. Posterior ganglion cyst.
5. Chronic Osgood-Schlatter disease.
POSTOPERATIVE DIAGNOSES: Left knee:
1. Medial meniscus tear.
2. Mild osteoarthritis.
3. ACL sprain.
4. Posterior ganglion cyst.
5. Chronic Osgood-Schlatter disease.
PROCEDURES PERFORMED: Left knee:
1. Examination under anesthesia.
2. Diagnostic arthroscopy.
3. Arthroscopic partial medial meniscectomy.
4. Arthroscopic excision of posterior ganglion cyst.
5. Arthroscopic chondroplasty of patellofemoral joint medial femoral
condyle.
6. Open excision of Osgood-Schlatter ossicle with tibial tubercle plasty
and debridement/repair of patellar tendon

ANESTHESIA: General, supplemental regional nerve block.
ESTIMATED BLOOD LOSS: Minimal.
INTRAOPERATIVE COMPLICATIONS: None.
DESCRIPTION OF PROCEDURE: Regional nerve block was performed in the
preoperative holding area. The patient was brought to the operating room
and placed under general anesthesia. The left knee was then closely
examined. The patient Lachman's was stable. If there was any difference between
the 2 sides, it was pretty subtle, and he did have a negative pivot shift
and the knee was otherwise stable with full motion, just being limited by
soft tissues in flexion. The left lower extremity was then prepped and
draped in routine sterile fashion. The limb was exsanguinated and
tourniquet inflated to 300 mmHg. We performed diagnostic arthroscopy.
Standard anterolateral and anteromedial arthroscopies were created. The
arthroscope was introduced in the knee joint. Superior pouch was normal.
The patellofemoral joint had some mild degenerative changes with some loose
fragments of cartilage, mostly grade 2, some small areas of grade 3. These
were debrided back to stable margin, but no full-thickness areas were
present. Medial and lateral gutters were normal. The medial compartment
was then entered, and there was a tear of the junction of the mid body and
posterior horn of the medial meniscus. It was resected back to stable
margin using arthroscopic basket and shaver. Medial articular surfaces of
the medial femoral condyle had some mild chondromalacia, which was
debrided. The patient did have a cyst on his preoperative MRI scan that was just
posterior to the PCL attachment. I did just open the capsule in that area,
being very careful around the vessels, and was able to drain the cyst and
debride it somewhat in that area. Intercondylar notch showed his ACL was
intact and that he just had had a sprain to it, but did not disrupt any
significant fibers to it. The lateral compartment was then entered.
Lateral meniscus and lateral articular surfaces were still in good
condition. The arthroscope and instruments were then removed. We then
made a longitudinal incision centered over the tibial tubercle area.
Dissection was carried down through skin and subcutaneous tissue,
identifying the tibial tubercle and patellar tendon. We sharply incised
the patellar tendon longitudinally and shelled out Osgood-Schlatter's
ossicle that was present just proximal to the tubercle, debrided some of
the tendon in that area, and then the actual tibial tubercle had some
spurring of it and we debrided that down to nice smooth tubercle, debrided
some of the tendon in that area. We did not completely detach the tendon,
but we did repair it back down to the tibial tubercle using a double-loaded
suture anchor to nicely reapproximate the tendon back down to the smoothed
off tubercle. The wound was then irrigated. We did use mini C-arm to confirm we had a nice smooth tubercle, and that the ossicle had been
removed. Wounds were then closed. Sterile dressing was applied.
Tourniquet was deflated. He tolerated the procedure well and was
transferred to recovery room in stable condition. There were no apparent
intraoperative complications.
 
This is not 27360, 27380, and is 27389 a typo for #3? I can see why 27360 would be chosen though. I can also see why someone would pick 27380. In my view, these are not accurate.
Regarding 27418 - I am not seeing that the tibial tubercle was moved, transferred, a bone block piece, or elevated to move the point of attachment to re-align the patellar tendon. (Cut and moved like in Fulkerson). It was smoothed and the ossicle was removed and the pattellar tendon re-attached. It may be that the provider needs education on documentation or this op report is not specific enough.

This appears to be more of excision of the ossicle and reattachment of the tendon, but no actual re-alignment/moving/repositioning.
See AMA CPT® Assistant - 2017 Issue 3 (March) Surgery: Musculoskeletal System (Q&A) (March 2017)
March 2017 page 10a Surgery: Musculoskeletal System Question: What is the appropriate code to report the excision of a bony ossicle on the knee caused by Osgood-Schlatter disease? Answer: Currently, there is no specific CPT code that describes this procedure. Therefore, code 27599, Unlisted procedure, femur or knee, may be reported. When reporting an unlisted code to describe a procedure or service, it is necessary to submit supporting documentation (eg, procedure report) along with the claim to provide an adequate description of the nature, extent, and need for the procedure; and the time, effort, and equipment necessary to provid...

My thoughts in parentheses:
1. Examination under anesthesia. (incidental/included)
2. Diagnostic arthroscopy. (incidental /ncluded)
3. Arthroscopic partial medial meniscectomy. (29881)
4. Arthroscopic excision of posterior ganglion cyst. (incidental and/or included in the 29881 because would probably be reported with 29785 which cannot be separately reported with 29881)
5. Arthroscopic chondroplasty of patellofemoral joint medial femoral
condyle. (included in 29881)
6. Open excision of Osgood-Schlatter ossicle with tibial tubercle plasty
and debridement/repair of patellar tendon (if the op note is complete and that is what was done, I would follow CPT Asst. and report the 27599)
 
Thank you for your response but I would like to know your opinion.

"I can see why 27360 would be chosen though. I can also see why someone would pick 27380. In my view, these are not accurate."

27360 is for partial excision (craterization, saucerization, or diaphysectomy) bone, femur, proximal tibia, and/or fibula (eg osteomyelitis or bone abscess). This is *normally* seen for infection and divot or crater-like piece is taken out and graft or abx is put in. It's bigger than "shelling" or "smoothing down". This isn't what we see in your op note for Osgood Schlater. I guess some folks would use 27360 for this procedure. But, you can't take credit for both that and 27418 as suggested in your 1st code list. Also, CPT Assistant is telling us what to code this as. Unless there is new guidance or a reputable source directing otherwise.

27380 is coded when the patellar tendon is torn or ruptured and sutured/repaired (primary). Someone saw the words, "and debridement/repair of patellar tendon" and automatically chose 27380. That's not what this procedure was. The provider incised the patellar tendon to access the ossicle and debrided some of the tendon.

Further, what diagnoses would be attached to support these codes?

This is an old thread in this forum however, Dr. Pechacek (RIP) answered it perfectly. https://www.aapc.com/discuss/threads/excision-of-bony-ossicles.148264/
