A modifier is used to indicate that a service or procedure has been altered by some specific circumstance but not changed in its definition or code. Modifiers may be used to indicate that a service or procedure has both a professional and a technical component, only part of a service was performed, a bilateral procedure was performed, or a service or procedure was provided more than once. A procedure modifier is required when a modifier clarifies or improves the reporting accuracy of the associated procedure code. This field links to the CPT Modifier reference file REF_CPT_MOD for Medical but to the REF_PROC_CODE_DENTAL for Dental.

This field contains the total charges for the service as reported by the provider. This is a money field containing dollars and cents. This field may contain a negative value.
This field includes all health plan payments, including withhold amounts, and excludes all member payments. This is a money field containing dollars and cents. This field may contain a negative value.
This is an amount that is required to be paid by a member before health plan benefits will begin to reimburse for services. It is usually an annual amount of all health care costs that are not covered by the member's insurance plan. To determine the total out-of-pocket/member responsibility for this service, you must sum this field with both Copay Amount (MC065) and Coinsurance Amount (MC066). This is a money field containing dollars and cents. This field may contain a negative value.
This amount is paid by the member and reflects the percent a member must pay toward the cost of a covered service. In many health insurance plans, the coinsurance a member is responsible for is capped after a certain dollar amount of eligible expenses has been incurred. Not all carriers can distinguish between the mutually exclusive fields of Copay Amount (MC065) and Coinsurance Amount. To determine the total out-of-pocket/member responsibility for this service, you must sum these two fields with Deductible Amount (MC067). This is a money field containing dollars and cents. This field may contain a negative value.
This field contains the preset, fixed dollar amount payable by a member, often on a per-visit/-service basis. Not all carriers can distinguish between the mutually exclusive fields of Copay Amount and Coinsurance Amount (MC066). To determine the total out-of-pocket/member responsibility for this service, you must sum these two fields with Deductible Amount (MC067). This is a money field containing dollars and cents. This field may contain a negative value.
This field contains the fee for service equivalent that would have been paid by the health care claims processor for a specific service if the service had not been capitated. Capitated services are services rendered by a provider through a contract under which payments are based upon a fixed dollar amount for each member on a monthly basis. Note that the provider did not receive this payment. Any payment for this service was made through capitation and that is not captured in this database. This is a money field containing dollars and cents. This field may contain a negative value.
This field indicates whether the current line is from an inpatient claim. The Inpatient flag is set to Y for any claim with at least one claim line having the following condition present: a REVENUE element (MC054) value of 110-239 or a BILLTYPE element (MC036) value of 11-12, 41-42, of 51-52. This flag is derived from the HCG value where the HCG high level category is hospital inpatient. Valid codes include: Y - Yes, an inpatient record; N - No, not an inpatient record
This is the key of the HCG value that links to the REF_HCG table to provide HCG information about the claim
Cases are a measurement of unique services. The meaning of the value found in cases vary by service type. For hospital inpatient services, cases represent admits. Hospital outpatient services, cases essentially represent unique events at the outpatient facility. For professional and other (ancillary) services, cases are visits, services, tests, etc. depending on the type of service. For prescription drugs, cases represent scripts. If cases are negative this represents an adjustment to a previously received service line.
Utilization is the count of the number of distinct services. Utilization counts differ according to the type of service. For hospital inpatient services it is the number of days spent in the facility. For hospital outpatient services it is the number of procedures delivered. For professional services it is the number of services delivered. For Rx services it is the number of prescriptions. For ancillary services it is the number of procedures performed. If the utilization is negative this represents an adjustment to a previously received service line.
This field contains the National Drug Code. Each drug product listed under Section 510 of the Federal Food, Drug, and Cosmetic Act is assigned a unique 10-digit, three-segment number. This number, known as the National Drug Code (NDC), identifies the labeler/vendor, product, and trade package size. The first segment, the labeler/vendor code, is assigned by the FDA. A labeler is any firm that manufactures, repacks, or distributes a drug product. The second segment, the product code, identifies a specific strength, dosage form, and formulation for a particular firm. The third segment, the package code, identifies package sizes. Both the product and package codes are assigned by the firm. The NDC will be in one of the following configurations: 4-4-2, 5-3-2, or 5-4-1.
This field contains the status of the claim as reported by the payer on the remittance. Note that the claim status code is specific to each service line of a claim. Claims processed as secondary may have dramatically lower payments for services rendered because another payer had primary responsibility. A small number of payers are unable to distinguish claims processed as primary from those processed as secondary. In studying the cost of a specific procedure, a claim that is not processed as primary may reflect only a partial payment. This field links to the REF_CLAIM_STATUS table. Valid codes include: 01:Processed as primary 02:Processed as secondary 03:Processed as tertiary 04:Denied 19:Processed as primary, forwarded to additional payer(s) 20:Processed as secondary, forwarded to additional payer(s) 21:Processed as tertiary, forwarded to additional payer(s) 22:Reversal of previous payment -1:Not specified (no claim status reported) -2:Not valid (invalid claim status code reported)
This field describes an injury, poisoning, or adverse effect using an ICD E-Code diagnosis. The user should search the Principal Diagnosis and Other Diagnosis fields (MC041, MC042, MC043, MC044, MC045, MC046, MC047, MC048, MC049, MC050, MC051, MC052, MC053) to identify all submitted ECodes. Note that the same E-Code may be reported in this field and in an Other Diagnosis field, depending upon the data reporter. This field links to the REF_ICD_DIAG file.
This code denotes the method of claim adjustment logic that was applied to create the final status of the claim for the Claim Final Status view. This is based upon information provided by data submitters during the registration process. However, it can be modified if the data proves that a different method is required. This field links to the REF_PROCESSING_RULES table.
This field contains an identification number representing a specific service defined as a unique member and date of service
