icd whats further expansion of code sets for additional specificity

by Prof. Winston Connelly 6 min read

The granularity of ICD-10-CM and ICD-10-PCS is vastly improved over ICD-9-CM and will enable greater specificity in identifying health conditions. It also provides better data for measuring and tracking health care utilization and the quality of patient care.

Full Answer

Is your ICD-10 diagnosis code specificity correct?

But ICD-10 diagnosis coding to the correct level of specificity—a more recent requirement—continues to be a problem for many in the healthcare industry. While diagnosis code specificity has always been the goal, providers were granted a reprieve in order to facilitate implementation of ICD-10.

Why do I need to assign subdivisions to ICD-10 codes?

Each ICD-10 code represents a unique diagnosis. That’s why you must always assign subdivisions until you have coded to the highest level of specificity when reporting ICD-10 codes to payers, claims clearinghouses, or billing and collection agencies.

When does the transition to ICD-10-CM/PCS take effect?

Transition deadline. The transition to ICD-10-CM/PCS code sets will take effect on October 1, 2015 and all users will transition to the new code sets on the same date.

What are the characteristics of an ICD-10-CM code?

Codes in the ICD-10-CM code set can have anywhere from three to seven characters. The more characters there are, the more specific the diagnosis. The first character is always alpha (i.e., a letter), but characters two through seven can be either alpha or numeric. Let’s take a look at an example.

What does it mean to code to the highest specificity?

Clinicians who must select ICD-9-CM diagnosis codes should use codes that provide the highest degree of accuracy and completeness (i.e., the greatest specificity). That usually means providing an ICD-9-CM code carried to the fifth digit.

What is the expansion of ICD?

When can an additional place of occurrence be coded?

Generally, a place of occurrence code is assigned only once, at the initial encounter for treatment. However, in the rare instance that a new injury occurs during hospitalization, an additional place of occurrence code may be assigned. No 7th characters are used for Y92.

What does ICD stand for in medical coding?

Is it necessary to use unspecified codes?

Unspecified diagnosis codes have acceptable, even necessary, uses. The unspecified code rate is not an error rate, but rather an indicator of the quality of clinical documentation and a qualitative measure of coder performance and coding results. Even CMS explicitly recognizes that unspecified codes are sometimes necessary.
