Guidelines tips

From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.

Each pressure ulcer gets its own L89 code for site and stage. A healing ulcer is coded to its documented stage, and deep tissue injury has its own stage code.

Guidelines I.C.12.a.1; I.C.12.a.5; I.C.12.a.7Pressure ulcer stagesRead the official text

Pressure ulcer stage, ulcer depth, BMI, NIHSS and coma scale may be coded from other clinicians' documentation. The diagnosis itself must be documented by the patient's provider.

Guidelines I.B.14Documentation by clinicians other than the providerRead the official text

Unstageable and unspecified stage are different codes. A completely healed ulcer at admission is not coded. If the stage progresses during an inpatient stay, two codes are assigned for the same site.
