Claim edit: Invalid procedure code format

Stedi now rejects 837P professional, 837D dental, and 837I institutional claims with a procedure code that isn't exactly 5 alphanumeric characters or is made up entirely of letters.

How the edit works

Procedure codes, such as medical CPT/HCPCS codes and dental CDT codes, identify a service performed during a patient visit.

Procedure code

Claim type	JSON API field	X12 element
837P professional	`serviceLines[].professionalService.procedureCode`	`SV1-01-02` (Procedure Code) of Loop `2400` (Service Line)
837D dental	`serviceLines[].dentalService.procedureCode`	`SV3-01-02` (Procedure Code) of Loop `2400` (Service Line)
837I institutional	`serviceLines[].institutionalService.procedureCode`	`SV2-02-02` (Procedure Code) of Loop `2400` (Service Line)

In a claim, all valid procedure codes must be exactly 5 alphanumeric characters with no spaces or special characters. They must also include at least one digit. A code made up entirely of letters, such as PHONE, isn't valid; an all-numeric code, such as 87070, is.

If a claim contains a procedure code with spaces or special characters, Stedi automatically removes the spaces and characters during validation. If the resulting procedure code has a length other than 5, or is made up entirely of letters, Stedi rejects the claim. This prevents later payer rejections, which are slower and can delay payment for the provider.

For 837D dental claims, Stedi also checks that the procedure code starts with the letter D, following the CDT code format.
