Sequelaq

A sequela is the residual effect (condition produced) after th t h f ill i j h t i t d

62

the acute phase of an illness or injury has terminated. There is no time limit on when a sequela code can be used. The residual may be apparent early, such as in cerebral infarction or it may occur months or years latercerebral infarction, or it may occur months or years later, such as that due to a previous injury. Coding of sequelagenerally requires two codes sequenced in the following order: The condition or nature of the sequela is sequenced fi t Th l d i d dfirst. The sequela code is sequenced second.

An exception to the above guidelines are those instances where the code for the sequela is followed by a manifestation code identified in the Tabular List and title ormanifestation code identified in the Tabular List and title, or the sequela code has been expanded (at the fourth, fifth or sixth character levels) to include the manifestation(s). The code for the acute phase of an illness or injury that led to code o t e acute p ase o a ess o ju y t at ed tothe sequela is never used with a code for the late effect.

BorderlineDiagnosesg

If the provider documents a "borderline" diagnosis65

If the provider documents a borderline diagnosis at the time of discharge, the diagnosis is coded as confirmed, unless the classification provides a specific entry (e.g., borderline diabetes). If a borderline condition has a specific index entry in ICD 10 CM it should be coded as such SinceICD-10-CM, it should be coded as such. Since borderline conditions are not uncertain diagnoses, no distinction is made between the care setting g(inpatient versus outpatient). Whenever the documentation is unclear regarding a borderline

diti d d t fcondition, coders are encouraged to query for clarification.

ICD-10-CM coding guideline I.A.17 states67

In contrast, the Code First/Use Additional Code notes provide sequencing order of th d ( d l i diti f ll dthe codes (underlying condition followed by the manifestation).

Codes for signs and symptoms may be reported in addition to a Codes for signs and symptoms may be reported in addition to a related definitive diagnosis when the sign or symptom is not routinely associated with that diagnosis, such as the various signs and symptoms associated with complex syndromes. The definitive diagnosis code should be sequenced before thedefinitive diagnosis code should be sequenced before the symptom code.

Signs or symptoms that are associated routinely with a disease process should not be assigned as additional codes, unless otherwise instructed by the classification.

ICD-10-CM contains a number of combination codes that identify both the definitive diagnosis and common symptoms of that diagnosis When using one of these combination codes andiagnosis. When using one of these combination codes, an additional code should not be assigned for the symptom.

Falls161

Code R29.6, Repeated falls, is for use for encounters when a patient has recently fallen and the reason for the fall is being investigated. C d Z91 81 Hi t f f lli i f Code Z91.81, History of falling, is for use when a patient has fallen in the past and is at risk for future falls Whenis at risk for future falls. When appropriate, both codes R29.6 and Z91.81 may be assigned together.

Sequelaq170

7th character S, sequela, is for use for complications or conditions that arise as a direct result of a condition such as scar formationresult of a condition, such as scar formation after a burn. The scars are sequelae of the burn. When using 7th character S, it is necessary to use both the injury code that precipitated theuse both the injury code that precipitated the sequela and the code for the sequela itself. The S is added only to the injury code, not the sequela code The 7th character S identifiessequela code. The 7th character S identifies the injury responsible for the sequela. The specific type of sequela (e.g. scar) is sequenced fi t f ll d b th i j dfirst, followed by the injury code.
