CO : Contractual Obligations denial code list

MCR - 835 Denial Code List  

CO : Contractual Obligations - Denial based on the contract and as per the fee schedule amount.

CO should be sent if the adjustment is related to the contracted and/or negotiated rate Provider’s charge either exceeded contracted or negotiated agreement (rate, maximum number of hours, days or units) with the payer, exceeded the reasonable and customary amount for the rendered service(s). Use this category when a joint payer/payee agreement or a regulatory requirement  has resulted in an adjustment that the member is not responsible for, or the provider’s charge exceeds the
reasonable and customary amount and for which the  patient is responsible.

CO (Contractual Obligation) assigns financial responsibility to the provider. When CO is used to describe an adjustment, a provider is not permitted to bill the beneficiary for the amount of that adjustment; or PR (Patient Responsibility) assigns financial responsibility to the patient. Medicare beneficiaries may be billed only when Group Code PR is used with an adjustment.


For CO denial code, We could not bill the patient but we could resubmit the claim with necessary correction according to Denial.


SOME IMPORTANT CO DENIAL CODES

Denial code CO 4 says that the code for the procedure is inconsistent along with the modifier used or that a necessary modifier is supposedly missing. Denial code CO 11 says that the diagnosis may be inconsistent with the involved procedure. Denial code CO 16 says that the service or claim lacks the necessary information needed for the adjudication. The denial code CO 18 revolves around a duplicate service or claim while the denial code CO 22 revolves around the fact that the care can be covered by any other payer for coordination of the benefits involved.


The denial code CO 24 describes that the charges may be covered under a managed care plan or a capitation agreement. The denial code CO 27 revolves around the expenses that are incurred after the coverage is terminated. The denial code CO 50 is about the non-covered services as these are not deemed a medical necessity by the concerned payer. The denial code CO 96 revolves around non-covered charges while the denial code CO 97 is about service and its benefit, whether or not it is included with the allowance or payment for any other service or any other procedure which has been already adjudicated. The denial code CO 109 deals with a service or claim that is not covered

  1. a intelligent as well as astute financial transfer for people who need their own household or some other dependents for being in financial terms secure even after they expire. Regrettably, on the other hand, quite a few policyholders are below insured, placing their loved ones at risk. Conversely, lots of people are in addition over-insured, investing in insurance they don't have the need forTruckers Insurance
