SECTION VI – BILLING ENTERALS TO MANAGED CAREORGANIZATIONS AND PRIVATE PAYERS FOR HOMECAREBilling enteral products to private indemnity andmanaged care payers uses many of the same principles asMedicare billing. However, these payers tend to be less strictabout the use of enteral products. In addition, the pricingmethodologies can differ significantly from Medicare.ENTERAL BILLING STRUCTURESMedicare uses a fee-for-service billing structure forpayment. In other words, there is a specific code for aproduct (e.g., a feeding tube) and a concurrentreimbursement amount or Medicare allowable rate.Private and managed care payers may accept thefollowing billing structures:Fee-for-ServiceSimilar to Medicare, in these billing structures, theprovider delineates a list of product codes as well asservice codes, then develops a price list that is eithernegotiated on a case <strong>by</strong> case basis with the payer orincorporated into a contract. Typical products and servicesincluded in this billing methodology are:❏ Specific enteral products❏ Enteral pumps❏ Enteral supplies❏ IV poles❏ Delivery and management servicesSometimes providers establish a fee-for-service rateon a product basis that includes delivery and managementservices, while other providers incorporate their servicechanges into their product fees in the same manner as withMedicare billing. When this methodology is used, theprovider typically uses the Medicare HCPCS codes.Per Diem RatesA per diem rate is a daily rate for products and services.This is a common methodology for billing enteral productsthat are delivered in a patient’s home. Because there are nospecific codes for per diem billing, the provider mustprovide a narrative explanation for the per diem rate.Example:Enteral products and services, 500 mL per day,pump, pole, supplies, inventory management, delivery- $35 per dayProviders use a number of different methods tocalculate per diem rates and these include:Method 1- Cost EstimatesEnteral Products Calories per day = $____________+ Supplies Cost per day = $____________+ Pump Cost per day = $____________+ Pole Cost per day = $____________+ Nursing or other service Cost per day = $____________+ Overhead Cost per day = $____________Total$______________May, 200271
Method 2 – AWP + Service ChargeMore and more payers are interested in an AverageWholesale Price (AWP) plus a service charge that includesenteral supplies and provider services. AWPs are found ineither the Red Book or the Blue Book and are established<strong>by</strong> independent sources. Private payers will negotiateeither a percentage off of AWP (e.g., -10% AWP), AWP oran AWP plus (AWP +5%) rate as well as the service chargefor the product. In order to establish a service rate, youhave to understand the costs including:❏ Enteral products❏ Enteral supplies❏ Enteral equipment❏ Pharmacy costs❏ Nursing costs❏ Delivery costs❏ Billing and collections costs❏ OverheadThese can be estimated for each product line or thefinance department can calculate a detailed Activity BasedCost (ABC) amount for typical enteral patients.CapitationCapitation is a form of payment which is made to aprovider on a per member per month (PMPM) basis.Capitation payments are generally made at the beginning ofthe month and they precede the provision of service tomembers. Per member per month rates are determined <strong>by</strong>estimating the cost of providing care to the given managedcare member population, then adding a profit factor to thecalculation. Capitation estimates are generally calculatedfor a period of one year because it is usually difficult tomake predictions beyond this period of time.Capitation payments are made to a providerregardless of the amount of services provided to thepopulation being serviced. If the provider’s costs ofservices are higher than expected, the provider losesmoney. If the provider’s costs of services are lower thanexpected, the provider makes money. The art of capitationis complex, and involves good estimation skills andappropriate financial information about the memberpopulation in order to calculate the best rate. The methodfor establishing capitation rates is to:❏ Make assumptions about the expected utilizationof provider services with the MCO enrolleepopulation; this is usually difficult to do becauseonly past and current utilization is available andoften this data is sketchy; providers should❏❏evaluate the potential volume in a managed careorganization and make assumptions about howmuch the current volume will increase ordecrease with their services.The average rate per service is determinedThe expected utilization is multiplied <strong>by</strong> theaverage rate per service, then this is adjusted <strong>by</strong>any member co-payment amount❏ This equals the pmpm capitation amountThe following is an example of a capitationcalculation:$600,000 utilization of providerservices expected÷ 20,000 enrollees$30 per member per year (pmpy)- $6 co-payment$24 pmpy÷ 12 month$2 pmpm capitation rateIn some capitation situations, enrollees areresponsible for paying a co-payment amount. If they are,the co-payment amount would be subtracted from the totalper member per month amount which would be paid <strong>by</strong>the managed care organization and the provider wouldcollect the co-payment amount directly from the enrollee.Managed care organizations may present providerswith data which they have generated internally.Oftentimes, this information is sketchy and may not beaccurate. Managed care organizations have differentcomputer systems, and it can be difficult for them to linkthese systems together to generate accurate data. In somesituations, the provider may be asked to work with theinformation systems department within the managed careorganization to develop a process to get specificinformation required <strong>by</strong> the provider.Managed care data, like internally generated data, willchange over time as the enrollee population shifts, newservices are covered, and the utilization of services shiftswithin the enrollee population. Ideally, providers will usea variety of methods to arrive at a capitation rate estimateand understand that it is nearly impossible to generate aperfect number. Capitation is a process of estimation, andas providers and MCOs work together, both become bettereducated about the meaning of these estimates.There are different methods of establishing capitationrates. These are percentage of premium, percentage ofpremium with a guarantee, flat per member per monthrates, and variable rates.72May, 2002
