Automated claim validation keeps the side of service that the record documents

Work processed after September 29, 2026 at 12:00 UTC carries this change.

What you will see

Automated claim validation (ClaimCleaner) checks the side of service on each line: the RT and LT modifiers, and the side in each diagnosis code. Validation now changes the right or left side only when the line documents that side, with one exception below. The sides that a line documents are the sides of its diagnosis codes and of its RT, LT or 50 modifier.

No undocumented side. Validation does not add an RT or LT modifier, or a right or left diagnosis code, for a side that the line does not document.
No reversed side. Validation does not change a documented right side to left, a left side to right, or a sided code to an unspecified code.
Both sides on one line. When a line documents both sides, validation does not choose one side. It can only make the line bilateral: modifier 50, or the bilateral code of the same condition.
Same condition only. When validation adds the side to a diagnosis code with an unspecified side, the new code must describe the same condition. For example, a dislocation code does not become a subluxation code.
Every diagnosis stays on the line. When validation corrects the side of two or more diagnoses on one line, each diagnosis gets its own correction and keeps its place in the list. A secondary diagnosis does not move to the first-listed position.
No retired codes. Validation does not add a diagnosis code that is not valid for the date of service. For example, it does not add M54.5 (low back pain), which is not billable for dates of service after September 30, 2021.
One exception. Validation reads the side of a diagnosis code from the code set. A few bilateral codes, for example M17.0 (bilateral primary osteoarthritis of knee), do not carry a side there yet. Validation reads such a code as a code with no side, so it can still add that code to a line that documents one side or no side, or put it in place of a right or left code of the same condition.

For example: an interventional radiology claim bills a thrombectomy of the right leg veins (37187) with I82.411 and I82.421 (right femoral and right iliac vein thrombosis) and no side modifier. Validation adds RT and keeps both right-side codes.

Nerve block lines and the side of the surgery

Validation no longer changes the side of the diagnoses on the main anesthesia line to match the RT or LT modifier of a nerve block line. The main anesthesia line keeps the side that the surgery documentation states.
When a nerve block line carries RT or LT and the surgery documentation states the other side, validation reports the difference. The autocoder does not show this report to a coder yet, so no alert appears for it. In a sample of 2,336 recent fully automated anesthesia cases, the difference occurred on 1 case.

Alert changes

No alert is added or removed.
ClaimCleaner Added ICD Code, ClaimCleaner Added Anesthesia Modifier and ClaimCleaner Added Surgical Modifier can appear less often, because validation makes fewer side changes. On radiology claims, ClaimCleaner-Added Contralateral Diagnosis Stripped (Undocumented) can also appear less often.

What to look out for

Expect fewer side changes from validation on anesthesia and radiology claims.
When the record does not document a side, the line keeps the side as coded. Add the side from the record when your payer requires it.
On a line that documents one side or no side, check a bilateral diagnosis that validation added, for example M17.0.
On a claim with a nerve block, compare the side of the block line with the side of the surgery. The autocoder does not ask about a difference yet.
Nothing changes in your configuration.
