Diagnosis Codes
ICD-10 Decimal Handling
Ritten automatically removes the ICD-10 decimal point when submitting claims to Stedi. The decimal is visible in the Ritten UI and on PDFs — this is expected and correct. It is stripped in the electronic submission.
If you receive a diagnosis rejection, it is almost always because the diagnosis code itself is not accepted by the payer, not because of decimal formatting.
Diagnosis Timing on Claims
Diagnoses are captured at the time the claim is created.
If a diagnosis was added to the client chart after the service was generated but before the claim was created, it will appear on the claim.
If a diagnosis was added after the claim was already created, delete the claim and recreate it to include the new diagnosis.
ICD-10 vs. DSM Codes
Ritten uses ICD-10 codes exclusively. If you previously saw codes listed under DSM, those have been consolidated into the ICD-10 list — duplicate entries were removed and only the ICD-10 version is kept. The codes themselves remain valid for billing.
Primary Diagnosis
If no primary diagnosis is explicitly designated on the client chart, Ritten will default to the first diagnosis in the list when evaluating diagnosis-based service rule overrides. Make sure clients have a designated primary diagnosis to ensure accurate rule matching.
Diagnosis Filtering on Service Rules
Service rule outputs can be configured to include only mental health diagnoses, only substance use disorder diagnoses, or all diagnoses on the claim.
