L98.0Pyogenic granuloma

L98.0 is the ICD-10-CM diagnosis code for pyogenic granuloma. It belongs to category L98 (other disorders of skin and subcutaneous tissue, not elsewhere classified), block L80-L99 (other disorders of the skin and subcutaneous tissue) and chapter 12 (diseases of the skin and subcutaneous tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within L98 (other disorders of skin and subcutaneous tissue, not elsewhere classified), L98.0 is specifically for pyogenic granuloma. Related codes cover Factitial dermatitis (L98.1), febrile neutrophilic dermatosis [Sweet] (L98.2), eosinophilic cellulitis [Wells] (L98.3), Non-pressure chronic ulcer of skin, not elsewhere classified (L98.4), Mucinosis of the skin (L98.5), other infiltrative disorders of the skin and subcutaneous tissue (L98.6), excessive and redundant skin and subcutaneous tissue (L98.7), other specified disorders of the skin and subcutaneous tissue (L98.8) and 2 more.

The conditions in its Excludes2 note aren't part of L98.0, but may be coded alongside it if the patient has both: pyogenic granuloma of gingiva (K06.8), pyogenic granuloma of maxillary alveolar ridge (K04.5) and pyogenic granuloma of oral mucosa (K13.4).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 602 (Cellulitis with MCC, relative weight 1.4273) and DRG 603 (Cellulitis without MCC, relative weight 0.8635), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 686.1 (pyogenic granuloma of skin and subcutaneous tissue).
