The Record ID communicates how the contents of a given row of data should be interpreted depending on which segment type the Record ID represents. Each type of segment collects different data elements so each segment type has a distinct layout. The first 3 characters identify the relevant file (e.g., ELG, PRV, CIP, etc.). The last 5 digits are the segment identifier padded with leading zeros (e.g., 00001, 00002, 00003, etc.). COT016 Values

For example, some states have Primary Care Case Management programs where the state pays providers a monthly patient management fee of $3.50 for each eligible participant under their care. This fee is considered a fixed payment. It is very important for states to correctly identify fixed payments. Fixed payments do not have a defined "medical record" associated with the payment; therefore, fixed payments are not subject to medical record request and medical record review.

For claims where payment/allowed amount is determined at the individual lines and when applicable, cost-sharing and/or coordination of benefits were deducted from one or more specific line-level payment/allowed amounts (PAYMENT-LEVEL-IND = 2), the allowed (ALLOWED-AMT) and paid (MEDICAID-PAID-AMT) amounts on the associated claim lines should sum to the total allowed (TOT-ALLOWED-AMT) and total paid (TOT-MEDICAID-PAID-AMT) amounts reported on the claim header.

For claims where payment/allowed amount is determined at the individual lines but then cost sharing or coordination of benefits was deducted from the total paid/allowed amount at the header only (PAYMENT-LEVEL-IND = 3), then the line-level paid amount (MEDICAID-PAID-AMT) would be blank and line-level allowed (ALLOWED-AMT) and header level total allowed (TOT-ALLOWED-AMT) and total paid (TOT-MEDICAID-PAID-AMT) amounts must all be populated but the line level allowed amounts are not expected to sum exactly to the header level total allowed.

For example, if a claim for an office visit and a procedure is assigned a separate line-level allowed amount for each line, but then at the header level a copay is deducted from the header-level total allowed and/or total paid amounts, then the sum of line-level allowed amounts may not be equal to the header-level total allowed amounts or correspond directly to the total paid amount. If the state cannot distinguish between the scenarios for value 1 and value 3, then value 1 can be used for all claims with only header-level total allowed/paid amounts.

COT068 Values
COT069 COT.002.069 MEDICARE-REIM-TYPE A code to indicate the type of Medicare reimbursement. COT069 Values
