CPT code for excision of posterior buttock ossification

E. maria Posted Fri 17th of April, 2015 17:00:57 PM

Help. How would you code for excision of posterior ossification 12 cm in lenght>

The left posterior buttock was addressed and an incision was made over the palpable ossification and extended about 2 inches in length. Superior flaps were made to both sides and the ossification was removed the majority was in the subcutaneous tissue just above the muscle. However, there were portions that did protrude into the muscle, this was excised in full. Specimen was 12-15 cm in length. The movement of the subcutaneous tissue was then done using electrocautery to close the defect and secured using a deep layer of Vicryl sutures. A second layer with 0 Vicryl sutures was placed in the subcutaneous space over the top of this and the skin was closed with Monocryl subcuticular stich. Can you please help with CPT and ICD-9?

AAE does not provide coding for operative reports and chart notes.

SuperCoder offers SuperCoding on Demand (SOD) ( for coding of an operative report or chart note and you can contact (866)228-9252 or e-mail for more information.

I wasn't asking you to code the operative report. I added additional information to describe the procedure done. Ossification would I use the excision codes?

From a CPT coding perspective, currently no specific code within the CPT code set describes excision of posterior buttock ossification. Therefore, unlisted code 27299, Unlisted procedure, pelvis or hip joint, should be reported. When reporting an unlisted code to describe a procedure or service, it will be necessary to submit supporting documentation (eg, the procedure report) along with the claim to provide an adequate description of the nature, extent, need for the procedure, and the time, effort, and equipment necessary to provide the service. Use ICD-9 code 728.X series.
