Changelog

Some EMRs print the CPT code that was selected when the case was booked. The booked code does not always match the procedure that was performed. A common example is a colonoscopy booked under a polypectomy code when no polyp was removed.

The autocoder now treats a printed code number as scheduling data, not as proof. The words in the record still count, including words in the booking or scheduling area. But the autocoder does not expand a bare code number into its full code description to add details the record does not state.

What you will see differently:

• Surgical codes follow the documented procedure. If the booking shows a polypectomy code but the report documents a diagnostic exam with no polyp removal, the claim carries the diagnostic code.
• Anesthesia codes for GI cases no longer inherit polyp removal or biopsy from the booked code. A screening colonoscopy with no intervention codes as a screening exam, with the correct payer handling for the PT modifier.
• Diagnosis codes tied to an assumed intervention (for example, a colon polyp diagnosis) appear only when the record documents the finding.

What to look out for: claims where the booked code and the documentation disagree now follow the documentation. If a procedure was performed but not documented, the claim will not include it. Ask the provider to complete the record, then resubmit the case.

Two claim building defects are fixed.

Each case is handled on its own. When one case in a batch was a gastrointestinal or an obstetric case, the special note handling for that case could carry over into the cases processed after it. Those later cases could then read the record differently than they would on their own. The special handling now stays inside the case that needs it.

The surgeon on the first line is the surgeon on the claim. When a case documents more than one surgeon, the autocoder used whichever surgeon it read last. The surgeon on the first line item now fills the claim surgeon. A later line from a different surgeon is recorded in the notes on the claim and does not overwrite it.

What to look out for: in high volume batches, a case that follows a GI or an obstetric case should now code the same way it would code on its own. On a case with more than one surgeon, check that the claim surgeon is the one your billing rules expect.

The screening diagnosis stays on a combined upper and lower GI claim. On a combined endoscopy case coded as 00813, both procedures need a supporting diagnosis. The autocoder now keeps the screening code Z12.11 on the claim as the second ranked diagnosis instead of dropping it. The order is fixed: the upper GI diagnosis ranks first, the screening code ranks second, and the colon findings (for example K63.5 or K62.1) rank third.

A new alert names a claim where the screening code is dropped anyway. The diagnosis validation step, or the limit on how many diagnoses a line can carry, can still remove the code. When that happens the claim carries the informational alert "Screening Diagnosis Dropped from Combined GI Claim", and the alert names what was removed.

The PT modifier rule for 00813 is described in the July anesthesia update.

What to look out for: on combined GI claims, expect Z12.11 to stay on the claim in second position. If you see the dropped screening alert, check whether the screening diagnosis belongs back on the claim before you release it.

Z86.010 is not billable, and the autocoder no longer uses it. That code became non billable on 2024-10-01 and was split into five character codes. The autocoder now selects Z86.0101 for a history of adenomatous or serrated polyps, which is the most common surveillance case. It selects Z86.0100 when the record does not document the type of polyp. It selects Z86.0102 for a history of hyperplastic polyps only. It selects Z86.0109 for another documented history of colon polyps.

A documented family history of polyps now codes to Z83.71. The autocoder used the family history code for digestive cancer before this change. A family history of polyps is not a family history of cancer, and Z83.71 is the correct code.

What to look out for: lower endoscopy claims with a documented polyp history no longer carry the parent code Z86.010. Review any claim that you already submitted with Z86.010, because the payer rejects that line. Correct it to the five character code that the record supports, then resubmit.

Aetna no longer turns surveillance into diagnostic. Aetna treats surveillance as screening, per the commercial payer guidance dated 2025-12-02. Aetna is removed from the surveillance to diagnostic list, and from the 00811 with PT group.

One payer label is corrected. The row that read BCBS DE, NY, PA and WV now reads Highmark in any state, plus BCBS DE and BCBS WV. The old label mixed Highmark plans with BCBS Pennsylvania plans that are not Highmark. BCBS Independence (Pennsylvania) now has its own rows: 00811 with PT for a lower endoscopy, and 00813 with Z12.11 first for a combined upper and lower endoscopy.

Five payers move to a different group. BCBS Michigan and Priority Health (Michigan) move to the 00811 with PT group. BCBS Arkansas, Anthem Connecticut and BCBS Illinois move to the 00812 with PT group.

The surveillance rule for Cigna, UHC and BCBS Nebraska now applies. An ordering defect meant that this rule never took effect. A surveillance case for these three payers now becomes diagnostic and produces 00811 without PT.

What to look out for: the code and the modifier can differ for the payers named above. Accuracy improves for each of those payers on a screening colonoscopy that converts to diagnostic.
