Provider documentation states: “A patient is seen today with DM type 2, peripheral neuropathy with diabetic ulcer of the left great toe…

A query opportunity exists when documentation is conflicting, ambiguous, or incomplete. The documentation "diabetic ulcer of the left great toe" lacks the required ICD-10-CM specificity regarding the depth of the ulcer (e.g., with skin breakdown, fat layer exposed, muscle necrosis, bone necrosis). Clarifying this detail is essential for accurate code assignment (L97.- series) and reflects the severity of illness. While the presence of an ulcer already risk adjusts, capturing the correct severity through a specific code is a key CDI function that impacts data quality and can reflect a higher level of patient complexity.

A. Nicotine dependence

The note states the patient "stopped smoking 2 years ago," which supports a history code, not active dependence.

B. Diabetes with complications

This is already clearly documented with "peripheral neuropathy with diabetic ulcer," which maps to a high-level HCC (HCC 18).

C. Morbid obesity

The documented BMI of 43 is sufficient for a coder to assign the code for morbid obesity (E66.01), which maps to HCC 22.

1. National Center for Health Statistics. (2023). ICD-10-CM Official Guidelines for Coding and Reporting FY 2024. The tabular list for non-pressure chronic ulcers (Category L97) requires a 6th character to specify depth, making this a required element for a valid code.

2. ACDIS/AHIMA. (2019). Guidelines for Compliant Query Practice—2019 Update. This joint practice brief outlines the principles for when a query is appropriate, including when clinical indicators suggest a need for "greater specificity or completeness" (p. 3), as is the case with the unspecified ulcer depth.
