Supply HCPCS Codes- A6234

The problem is not the revenue code but the HCPCS code.  In this instance the HCPCS code captures a dressing.  The only time you would report this code on a claim is if you were providing it as a take home supply, in which case, revenue code 623 would be appropriate.  

A-codes that represent supplies should not be reported to Medicare.  This was discussed several years ago in CMS literature.  Unless you have another payer who requires the reporting of these codes for reimbursement purposes, you may want to remove A-codes from your Chargemaster.  This supply in question should be reported under revenue code 272 without a HCPCS code.

HCPCS
The Healthcare Common Procedure Coding System (HCPCS), often pronounced by its acronym as "hick picks," is a set of health care procedure codes based on the American Medical Association’s Current Procedural Terminology (CPT). The Healthcare Common Procedure Coding System (HCPCS) was established in 1978 to provide a standardized coding system for describing the specific items and services provided in the delivery of health care. Such coding is necessary for Medicare, Medicaid, and other health insurance programs to ensure that insurance claims are processed in an orderly and consistent manner. Initially, use of the codes was voluntary, but with the implementation of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) use of the HCPCS for transactions involving health care information became mandatory.

CMS
The Centers for Medicare & Medicaid Services (CMS), previously known as the Health Care Financing Administration (HCFA), is a federal agency within the United States Department of Health and Human Services (DHHS) that administers the Medicare program and works in partnership with state governments to administer Medicaid, the State Children’s Health Insurance Program (SCHIP), and health insurance portability standards. In addition to these programs, CMS has other responsibilities, including the administrative simplification standards from the Health Insurance Portability and Accountability Act of 1996 (HIPAA), quality standards in long-term care facilities (more commonly referred to as nursing homes) through its survey and certification process, and clinical laboratory quality standards under the Clinical Laboratory Improvement Amendments.
