Local Coverage Determinations

“I am looking for a relatively concise explanation regarding Medicare’s policy on palliative care and coverage for diabetics and non-diabetics. As of late, fewer and fewer charges for nail debridement and keratosis debridement are being reimbursed. I have tried to search through Medicare’s guidelines but there is not enough time in a year to sift through the documentation. Is there such a thing as a concise explanation for Medicare’s guidelines for palliative care and CPT codes with ICD-10 codes?”
