Time to Update ICD-10

ICD-10 launched a little over a year ago and has now undergone its first update. The October 1, 2017 update was a sizable list of changes that had accumulated during the enforced code freeze in our long transition from ICD-9 to ICD-10.

October 1, 2017 also marked the end of the CMS imposed “period of flexibility,” during which non-specific codes were accepted. Providers now must strictly avoid unspecified codes if possible. Physicians should also expect more stringent auditing of claims. Codes with unspecified laterality, for example, and other commonly known information at the time of encounter are all subject to scrutiny.

The Importance of Documenting and Reporting Laterality

Laterality is a unique concept found in ICD-10 and is an important component when documenting information in a medical record. If a diagnosis includes right or left side, for example, or proximal or distal in play, documentation should clearly state this information. Thirty-six percent of all ICD-10 codes distinguish laterality (right versus left). Physicians should always document complete and accurate information to support a specific diagnosis; this now includes specifying laterality details.

Below, are a few examples in which laterality is required. While these diagnoses are commonly found in primary care and the emergency department, they remain a good reminder for all physicians. You will note, that the laterality character is most often the fifth or sixth character of the code. You will also note, that while laterality is frequently right or left, there are several instances when laterality is simply designated by a more specific area.

As you can see in the examples provided, there is great importance in documenting laterality to the injury and/or treatment provided during the patient encounter to ensure proper reimbursement.

Important Coding Guideline Changes

New guidelines help define an episode of care when selecting the seventh character for injuries. The guidelines now explain that the seventh character “A” is appropriate for encounters when the patient receives active treatment for a condition to initiates the healing process.  By contrast, a seventh character “D” is used for encounters after the patient has completed active treatment of the condition, or in other words when the healing process has been established. Below is an example of how those seventh characters would be used.

A patient is evaluated in the Emergency Room and diagnosed with a Greenstick fracture of the shaft of the left radius. A splint is applied pending reduction of swelling.  Code S52.312A is assigned because the patient is receiving active management.

The same patient then goes to her family physician’s office for further treatment. Closed reduction and casting are performed. Code S52.312A is once again assigned because she is again receiving active management/treatment.  

The patient then returns for follow-up. The cast is replaced and code S52.312D is reported because the patient is now in the healing phase and active treatment has been completed.

Coding Changes To Be Aware Of

Here is a brief synopsis of some of the coding changes you should review and, if appropriate, use to update your coding systems including superbill/charge ticket (electronic and/or paper), EHR and practice management (PM)/billing system to prevent claims rejections, delays and denials.
