Hoping I can get some help on both ICD-10 Diagnosis and CPT on this one. Thanks in advance

Patient has Chronic Ulceration with Osteomyelitis thrid toe right foot (L97519;L03031;M86171)

Procedure: Attention was directed to the distal aspect of the patient’s third toe right foot where an
incision was placed circumscribing the toe just distal to the distal interphalangeal
joint. The incision was deepened down to bone. The distal interphalangeal joint was
identified and the toe was disarticulated at this joint. The distal aspect of the toe was
then excised in total and sent to Pathology for further inspection. Aerobic and anaerobic
cultures were then taken from the joint. The head of the middle phalanx was resected
using power instrumentation. The middle phalanx appeared to be healthy. The bone was
hard and white. No drainage was noted. The remaining portion of the middle phalanx was
rasped smooth. The surgical site was thoroughly irrigated with sterile saline. The deep
structures were closed wit h 3-0 Vicryl and the skin was closed with 4-0 Prolene. Sterile
compressive dressings were then applied. At this time, the tourniquet was released and
intravenous sedation was discontinued.

I am looking at 28825 with Modifier T7
