Four tasks that form a single chain

The four tasks are in the order a claim actually travels, and writing them as four separate essays wastes the structure the brief has handed you. Medical necessity is the thread. A payer will pay for a service when the documentation shows the service was reasonable and necessary for the patient's condition, and every element of the assignment is a place where that showing either succeeds or fails. The record supplies the longitudinal context; the SOAP note supplies the encounter-level reasoning, where the assessment section is the load-bearing one because that is where the diagnosis justifying the service is stated; the operative report supplies the procedural detail that determines which procedure code is defensible. The coverage determination then decides whether the showing was accepted, which is why the four tasks appear in this order. Write it as one chain and the paper stops being four essays stapled together.

The operative report deserves the most attention because it is the section where students usually generalise. A coder cannot assign a procedure code from the header alone: the indications establish medical necessity, the findings often differ from the preoperative diagnosis and it is the postoperative diagnosis that codes, and the body of the report determines the extent of the procedure, whether an approach converted, and whether an additional procedure was separately identifiable rather than bundled. Say those things specifically. Then finish on coverage determinations, which are the rules that decide the question at the payer's end. A national determination applies uniformly across the programme; a local determination is issued by a regional contractor and can differ between jurisdictions, which is why the same service with the same documentation may be covered in one state and denied in another. That fact is the single most useful thing in the paper.

Likely learning objectives

  • Trace medical necessity as the thread connecting record, note and claim.
  • Identify the assessment section as the diagnostic justification in a SOAP note.
  • Explain why the postoperative diagnosis codes rather than the preoperative one.
  • Distinguish national from local coverage determinations and their consequences.

In order to properly code a bill for medical necessity, it is important to understand the electronic medical record. This record contains information about the patient’s health both before and after the treatment and has the data needed to assure a payer that the treatment was necessary. Tasks: Explain the contents of the medical record. Describe SOAP notes—subjective, objective, assessment, and plan. Explain operative reports function in medical necessity coding. Explain National and Local coverage determinations. Submission Details: Submit the report as a 5- to 10-page Microsoft Word document. Use APA standards for citations and references. Cite a minimum of three outside peer-reviewed sources to support your assertions and save it as SU_HCM1201_W3_Project_LastName_FirstInitial.doc. Submit the report to the Submissions Area by the due date assigned. Cite any sources using correct APA format on a separate page. The majority of procedures and services are reported using CPT (HCPCS level I) codes. However, CPT does not describe durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS), as well as certain other services reported on claims submitted for Medicare and some Medicaid patients. Therefore, the CMS developed HCPCS level II national codes to report DMEPOS and other services. (Medicare carriers previously developed HCPCS level III local codes, which were discontinued December 31, 2003. Medicare administrative contractors (MACs) replaced carriers, DMERCs, and fiscal intermediaries. HCPCS Level I HCPCS level I includes the five-digit CPT codes developed and published by the American Medical Association (AMA). The AMA is responsible for the annual update of this coding system and its two-digit modifiers. (CPT coding is covered in Chapter 7 of this textbook.) HCPCS Level II HCPCS level II (or HCPCS national codes) were created in 1983 to describe common medical services and supplies not classified in CPT. HCPCS level II national codes are five characters in length, and they begin with letters A–V, followed by four numbers. HCPCS level II codes identify services performed by physician and nonphysician providers (e.g., nurse practitioners and speech therapists), ambulance companies, and durable medical equipment (DME) com- panies (called durable medical equipment, prosthetics, orthotics, and supplies [DMEPOS] dealers). Orthotics is a branch of medicine that deals with the design and fitting of orthopedic devices. Prosthetics is a branch of medicine that deals with the design, production, and use of artificial body parts . ● Durable medical equipment (DME) is defined by Medicare as equipment that can with- stand repeated use, is primarily used to serve a medical purpose, is used in the patient’s home, and would not be used in the absence of illness or injury. ● Durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) include artifi- cial limbs, braces, medications, surgical dressings, and wheelchairs. ● Durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) dealers supply patients with DME (e.g., canes, crutches, walkers, commode chairs, and blood- glucose monitors). DMEPOS claims are submitted to DME Medicare administra- tive contractors (DME MACs) that replaced durable medical equipment regional carriers (DMERCs) that were awarded contracts by CMS. Each DME MAC covers a specific geographic region of the country and is responsible for processing DMEPOS claims for its specific region. When an appropriate HCPCS level II code exists, it is often assigned instead of a CPT code (with the same or similar code description) for Medicare accounts and for some state Medicaid systems. (Other payers may not require the report- ing of HCPCS level II codes instead of CPT codes, so coders should check with individual payers to determine their policies.) CMS creates HCPCS level II codes: Medical Billing And Coding DQ 2 For services and procedures that will probably never be assigned a CPT code (e.g., medications, equipment, supplies) ● To determine the volumes and costs of newly implemented technologies New HCPCS level II codes are reported for several years until CMS initiates a process to create corresponding CPT codes. When the CPT codes are published, they are reported instead of the original HCPCS level II codes. (HCPCS level II codes that are replaced by CPT codes are often deleted. If not deleted, they are probably continuing to be reported by another payer or government demonstra- tion program.) ExAMPlE: HCPCS level II device code C1725 is reported for the surgical supply of a “catheter, transluminal angioplasty, nonlaser method (may include guidance, infu- sion/perfusion capability)” during vascular surgery. Thus, when a CPT code from range 35450–35476 is reported for a transluminal balloon angioplasty procedure, HCPCS level II device code C1725 is also reported as the surgical supply of the catheter. cOding tip: HCPCS LeveL ii NatiONaL COdeS The HCPCS level II national coding system classifies similar medical prod- ucts and services for the purpose of efficient claims processing. Each HCPCS level II code contains a description, and the codes are used primarily for billing purposes. ExAMPlE: DMEPOS dealers report HCPCS level II codes to identify items on claims billed to private or public health insurers. HCPCS is not a reimbursement methodology or system, and it is important to understand that just because codes exist for certain products or services, cover- age (e.g., payment) is not guaranteed. The HCPCS level II coding system has the following characteristics: ● It ensures uniform reporting of medical products or services on claims. ● Code descriptors identify similar products or services (rather than specific prod- ucts or brand/trade names). ● HCPCS is not a reimbursement methodology for making coverage or payment determinations. (Each payer makes determinations on coverage and payment outside this coding process.) Responsibility for HCPCS Level II Codes HCPCS level II codes are developed and maintained by the CMS HCPCS Work- group and do not carry the copyright of a private organization. They are in the public domain, and many publishers print annual coding manuals. Some HCPCS level II references contain general instructions or guidelines for each section; an Appendix summarizing additions, deletions, and terminol- ogy revisions for codes (similar to Appendix B in CPT); or separate tables of drugs or deleted codes. Others use symbols to identify codes excluded from Medicare coverage, codes where payment is left to the discretion of the payer, or codes with special coverage instructions. In addition, most references provide a complete Appendix of current HCPCS level II national modifiers. CMS has stated that it is not responsible for any errors that might occur in or from the use of these private printings of HCPCS level II codes. Types of HCPCS Level II Codes HCPCS level II codes are organized by type, depending on the purpose of the codes and the entity responsible for establishing and maintaining them. The four types are: Effective January 1, 2005, CMS no longer allows a 90-day grace period (tradition- ally, January 1 through March 31) for reporting discontinued, revised, and new HCPCS level II national codes on claims. There is also no 90-day grace period for implementing mid-year HCPCS level II national coding updates. Permanent national codes Miscellaneous codes Temporary code Medical Billing And Coding DQ 2
