ICD-10-CM presumes a causal relationship between two conditions that are linked by the terms “with” or “in” in the Alphabetic Index or instructional note in the Tabular List. With the clarification published of the understanding of the term “with,” there have been many eye-opening clarifications in coding (like in diabetes and now with GI bleeding). This differs from ICD-9-CM as the causal relationship was not assumed.
The word “with” in the Alphabetic Index is sequenced immediately following the main term, not in alphabetical order.
Please Note: As of October 1, 2018, the OCG FY 2019 clarify that “with” or “in” either under the main term or subterm presumes a causal relationship between the two conditions. Prior to this, the OCG only stated the main term.
GI Bleeding and Possible Sources “with” Bleeding:
The cause/etiology of GI bleeding is not always easily determined. During procedures, to work the bleeding up, there are often multiple potential sources of bleeding found but not identified as the culprit. Many of these findings have “with” or “in” in the main or subterms. When this is the case, the condition(s) would be coded as bleeding. If there are multiple findings all of these would be reported as bleeding if “with” or “in” is listed.
Causes (Common) of GI Bleeding:
Colon or rectal polyps (not specified as inflammatory)
Ulcerative esophagitis or esophageal ulcerations*
The “*” beside the diagnoses/causes above indicate that the causal relationship is made when the conditions are found, and the patient also has a diagnosis of GI bleeding.
The publication of this Q&A in the 3Q 2018 AHA Coding Clinic should help coders in determining when to code “with” conditions.
Outpatient Coding Tip
A combination code indicating a presumed linkage using the terms “with” or “in” is not appropriate for uncertain diagnoses in the outpatient setting. Instead, the Uncertain Diagnoses guideline applies for outpatient coding. The diagnosis should be coded to the highest degree of certainty for the visit.
