CO-282 Denial Code: Code Inconsistent With Type of Bill

What CO-282 means

CARC 282 says the procedure or revenue code is inconsistent with the type of bill. It applies to institutional claims (UB-04 or 837I). The type of bill tells the payer what kind of facility is billing, what kind of care was provided (for example inpatient, outpatient, or skilled nursing), and where the claim sits in the billing sequence. Every revenue code and procedure code on the claim has to make sense for that combination.

When a line doesn’t fit, such as an inpatient room and board revenue code on an outpatient bill, or a service that type of facility can’t bill, the payer denies it with CO-282. The usage note points to the 835 Healthcare Policy Identification segment for the payer’s specific edit.

Common causes

  • Inpatient versus outpatient mix-ups, such as outpatient observation services billed on an inpatient type of bill or the reverse.
  • Revenue codes limited to certain facility types, like SNF, home health, or hospice codes on a hospital bill.
  • Services not allowed for the facility type, such as professional-only codes on a facility claim.
  • Wrong frequency code, so the type of bill implies an interim or replacement claim that doesn’t match the lines.
  • Swing bed or distinct part units billed under the wrong facility type.

How to fix it

  1. Check the patient’s status and setting for each date, including admission orders and observation periods.
  2. Review the type of bill in form locator 4 for facility type, care type, and frequency.
  3. Review revenue and procedure codes for each line against payer and program rules for that type of bill.
  4. Correct the claim and submit a replacement using the payer’s frequency code rules.
  5. Split the claim if services belong on different bill types.

How to prevent it

  • Map revenue codes to allowed bill types in your charge master and billing system.
  • Confirm patient status changes, such as observation to inpatient, before final billing.
  • Train staff on type of bill structure for each facility and unit type.
  • Scrub claims for code and bill type conflicts. A Claims Validator can flag revenue codes that don’t fit the type of bill.

Specialty notes

Critical access hospitals with swing beds, facilities with distinct part units, and hospital-based clinics are especially prone to CO-282 because the same patient can move between bill types.

Remark codes that may appear with CO-282

  • MA30 (Missing/incomplete/invalid type of bill.): The type of bill is missing, incomplete, or invalid.
  • N34 (Incorrect claim form/format for this service.): Incorrect claim form or format for this service.

  • CO-306 (Type of bill is inconsistent with the patient status.): Type of bill inconsistent with the patient status.
  • CO-135 (Interim bills cannot be processed.): Interim bills can't be processed, a frequency-code issue.

CO-282 FAQ

What is a type of bill?

A code in form locator 4 of the UB-04 (or the claim frequency and facility codes in the 837I) that identifies the facility type, the type of care, and the billing sequence, such as admit-through-discharge, interim, or replacement.

What causes CO-282 most often?

Using an inpatient type of bill for outpatient services or the reverse, billing services that the facility type can't provide, or using a revenue code limited to a different setting.

How do I fix CO-282?

Confirm the patient's status and setting for the dates billed, then correct the type of bill or the revenue and procedure codes. Submit a replacement claim using the payer's frequency code rules.

Does CO-282 affect professional claims?

No. Type of bill applies to institutional claims. Professional claims use place of service instead, where CO-5 and CO-58 are the related codes.
